Compact, Fast and Precise In-circuit-Function Test System

At Electronica 2014 REINHARDT System- und Messelectronic GmbH presents the compact ATS-UKMFT 616 In-circuit- and Function test system. This test system for loaded electronic PCBs finds production faults such as solder short circuits, faulty component placements or defective components and displays these faults graphically. It checks the function of the PCB, adjustment of the components and programming ICs are further features of this test system.

The basic version comes with two programmable complementary PSUs, one programmable sine-square wave generator, 32 In-circuit- and Function measuring channels, 32 bi-directional logic channels and 32 stimulus channels. The test system can be expanded with another two of the many REINHARDT-modules. A total of max. 224 In-circuit- and Function measuring channels can be built into this test system.

The fast measuring unit of the test system includes the In-circuit test with short circuit and interrupt test, solder defect and component test as well as the function test with DC-, AC- and peak voltage, time and frequency, logic channels, transient recorder (oscillograph), distortion factor and Fourier analysis. Of course external sources can be integrated.

For fast generation of a test program, there are CAD-interfaces, wizards and a number of useful tools. Boundary Scan Test (RBS100) or optical display test are options. For quality management there is a statistics function (standard), an optional ODBC-interface helps in integrating databases and connection to an MES-system is available too.

ATS-UKMFT 616 replaces the widely used ATS-UKMFT 625 and is downwards compatible. REINHARDT develop and produce hardware and software themselves, this grants longtime availability and swift service.

Two fixture models are available for this test system, fixture type 127 with a working area of 191.5 x 172 mm and type 147 with a working area of 360 x 230 mm.

ATS-KMFT 670-6 New Multi-Function Test System

For 34 years, REINHARDT System- und Messelectronic GmbH have been developing and producing computer-controlled test systems for electronic PCBs, modules and devices. With new hardware and software the latest test system has gained speed enormously so that the tests are up to 30 % faster than before. More modules can be used in this test system: While formerly 1,248 In-circuit- and Function test channels could be used in the basic system, there is now room for 1,440 channels, with expansion racks even up to 4,320 channels. The most important feature of this test system is its highly praised test and edit software which is based on more than 120 engineers' years. It comes with the basic system and provides all functions which are required in the field.

The test system provides all that is required for stimulation and supply of the device under test, e.g. 4-quadrant PSUs, 0 to ±38 V, 500 mA, resolution 1 mV or 10 µA for In-circuit and Function test. ADM 670, the very fast analog-digital measuring unit is also part of the basic unit.

The new multi-function board is standard and provides a USB-Port up to 480 MHz. Its RS232/422/485-interface can be programmed between 300 Hz and 1.25 MHz. An SPI-Bus can be programmed from 2.5 kHz to 10 MHz with levels between 1.8 V and 5 V. Two I2C-bus systems can be programmed between 56 kHz and 1 MHz. For Inline-integration and control there is a 16 Bit wide bus which can be set between 1.8 V and 5 V. A pulse generator can be programmed from 1.8 V to 5 V or from 0.6 Hz to 10 MHz and pulse width from 50 ns to 0.8 s.

With options such as Boundary Scan-Test, LED, colour and intensity test as well as display test (LCD), solder defect test for BGAs and Beam Lead ICs, polarity test for Aluminium-elcaps and Tantals as well as own test fixtures, these test systems have become the most powerful test systems in the European market.

ATS-UKMFT 627 New Combined In-circuit-Function Test System

The basic version of the combined In-circuit-function test comes with 32 bi-directional logic channels, 32 multi-matrix channels and 128 In-circuit- and function measuring channels (expandable to max. 608). Its in-circuit- and function measuring unit has more than 60 measuring ranges incl. transient recorder functions and Fourier analysis. 2 programmable, complementary twin PSUs, 0 to 24 V, supply the DUT and stimulate signals as does the sine and squarewave generator. This test system is also available with optional test fixtures (working area 192 x 172 mm or 360 x 230 mm) for precise contacting of the PCB.

ATS-UKMFT 627 stands out due to its enormous speed in the practical test speed (typically 3.6 ms per component) and the short time for programming.
As usual high stability and careful handling of the PCBs under test has been a major concern, because many companies do not know that their PCBs are stressed unnecessarily. There are still test systems in the market which apply measuring voltages far above 280 mV to ICs and components. In the in-circuit test this can destroy or damage the component and cause early failures. REINHARDT has found the balance between extremely low test voltage and high currents, very fast test speed, but at high test accuracy. Therefore, other than some competitors, we do not execute the component test in 10-15 % limits and in a comparator window without exact statistical evaluation. Our measuring routines have been developed with the experience of many years and are constantly being worked on in order to reach the best test speed. ATS-UKMFT 627 is not only statistically fast, i. e. that only the theoretically possible test speed per component is summed up, it is also fast in practice with all the conditions of a typical analog-digital component. Test times can be improved by up to 50 % in the latest version, especially for components with a lot of analog technique. That the high speed-measuring unit and the resp. measuring matrix are only 50 mm below the DUT, also results in the fast test speed. For evaluating signals in function test, an own 50 MHz transient recorder can also be integrated. It also benefits from the short connections to the DUT.

ATS-UKMFT 627 can be expanded with the REINHARDT-software modules, such as the new RBS 100 Boundary Scan module. Apart from short-circuit and interrupt test, this boundary scan test can also be used in the analog and digital function test.

BOUNDARY SCAN Together with Analog and Digital Function Test

Since Boundary Scan Test was adopted by the IEEE-syndicate in 1990, the short-circuit and interrupt test with the Boundary Scan-method has become an important test method. The PCB under test has been designed and built especially for this test method. The currently used methods operate cryptically and require intensive computer skills and practice in order to create such programs with pretty high cost.

The programs for our test method are mainly generated automatically so that no engineer is required for creating a program in typically 1-2 hours. We have made programming easy and have adapted it to the usual REINHARDT-standard so that skilled workers can program it on their own after 5 hours instruction. As a producer of test systems who provides both in-circuit and function test, we offer evaluation electronics for analog and digital. With that, we execute short-circuit and interrupt test. With the help of serial digital information we generate patterns which then test the function in detail via logic and the logic boards which are connected to the interfaces. This method can also be used for the analog part or for the conversion into serial data such as e.g. interfaces, in order to stimulate them with the data via the Boundary Scan function and measure the resp. tests on the analog side or on the fieldbus side. Of course, it is also possible to feed in analog data via our test system and read and evaluate them via Boundary Scan so that a test of analog input values is possible with Boundary Scan.

In cost and practice-oriented operation we differ enormously from all other products in the market.

TRA670 Transient Recorder (Oscilloscope)

In testing electronic PCBs, it is necessary to check signals with any curve forms. For many years, this has been done with our TRA470 tranisent recorder which was used to up to 10 MHz. Compared to our new solution TRA670, the TRA470 was less efficient in its operation and convenience.

With 12 bit resolution, 50 MHz band width and samples up to 250 MHz, the TRA670 transient recorder is a lot more efficient than its predecessor. It is used for measuring and graphically displaying signal forms of any kind, from pure sine frequencies, squarewaves, completely free curve forms, distortion factor to Fourier analysis. Frequencies, periods, rise times, fall times, pulse widths and peak voltages can be measured. A special feature of the transient recorder is the envelope curve function. In a default window, the envelope curve can be learnt in a few seconds and can then be corrected and worked on very conveniently: You just touch the envelope curve with the mouse and form it as required. In this way, the envelope curve is modified in a few seconds. Special feature of the transient recorder are its 8 coaxial and 9 high frequency channels with 50 Ω input impedance (each channel can be switched between 50 Ω or 1 MΩ). With the standard measuring matrix, the transient recorder can still be applied to all points. The transient recorder is potential-free so that the signals need not necessarily be measured related to ground. Max. input voltage is 100 V, max. resolution is 250 µV. It is possible to use several TRA670 in a test system in order to measure curve forms in parallel too and display it via an external trigger output.

As ATS-KMFT 670-5 already covers the In-circuit- and Function test, Boundary Scan-test and high voltage test, the new TRA670 is another improvement in evaluating curve forms up to 50 MHz and it provides even more test accuracy and test depth for our test. The TRA670 transient recorder can also be used in the UKMFT-test system family.

MWS 3 Smallest Weather Station

MWS 3, the new and smallest weather station is made of high quality steel. It measures the environmental parameters temperature, humidity, wind direction and wind speed with 0.05 km/h resolution, wind peak and average wind; dewpoint and windchill are calculated. The magnetic scanning of wind speed reduces the mechanical resistance ot a minimum and provides  many years operation without wear. MWS 3 stands out due to its very small size and little current consumption.

The microprocessor within the sensor linearises and digitises the measured values. In our house, the serial interface can be configured as RS232, RS485 or RS422. The data in ASCII-format are faultlessly transmitted over 100 m with RS232 and more than 1,000 m with RS485/RS422. The baudrates can be set. As all REINHARDT-weather stations, MWS 3 offers highes stability and reproducibility. Voltage supply is below 10 mA in the range between 6 and 30 V.

With a connection cable and a multi-way connector, the weather station is commissioned in a single plug procedure. This takes just a few minutes.

Applications are e.g. mobile environmental measuring technologies, central building control systems, automobile and tyre manufacturers, electric companies, tourism.

High Voltage Test in the In-circuit and Function Test

For many years, In-circuit test and function test used to be in the range between ±15 V. The new technologies and especially the electronization of domestic engineering which are usually  230 V and 400 VAC require new modules which must be tested like the low-voltage current modules. To the contrary, they must be tested so that in the range between 230 V and 400 V neither man nor thing are damaged and the necessary security is ensured.

Our new stimulus matrix boards such as RML32, MMX670 and MMX72 were developed for up to 500 V. HSM670 covers another range up to 1,500 V so that voltages in this range can be stimulated and measured. In a suitable expansion, you can execute cable and wiring measurements up to 1,500 V and currents up to 5 A. The measuring technique of ATS-KMFT 670-5 support the high voltage matrix board and enables you to measure components, harness and devices which create or process voltages up to 1,500 V. The standard ATS-KMFT 670-5 is therefore used for In-circuit test, Boundary Scan test, Function test analog and digital, as well as for wiring test on harness or networks up to 1,500 V. Our comfortable programming is menu-driven and has various program generators. Our programming and the test that follows are as competitive, easy and convenient as no competitor can offer.

MMX670 New Stimulus Matrix with 2 Precision PSUs

The new MMX670 stimulus matrix is designed for applying external sources or signals and for measuring with external measuring devices. Applying sources and signals to different points of the device under test or of external signals such as e.g. Fieldbus systems or controlling external relays are only a few examples for the universal use of this matrix board. In the four-terminal resistance measurement of the In-circuit test these stimulus matrix channels are used as measuring channels. There are 48 stimulus channels (one-wire technique) for potentialfree stimulation and measurement in a total of 12 groups with 12 in- and outputs. The High and the Low branch of the new MMX670-board can be programmed individually.
The two 16 Bit precision PSUs on this board have improved resolution (1 mV) and accuracy. Two 16Bit-PSUs, 0 to + 38 V, max. 500 mA, can be programmed in 1 mV-steps. Current can be programmed in 10 µA-steps from 15–500 mA. Current limitation can be programmed with 10 µA resolution. PSU2 can also be coded from 0 V to -38 V.

Test Fixture Production System AAE-CNC 2

The bed-of-nails-fixture for the In-circuit- and Function test comes last in development and quality management, but it can only be built when the development is completed. If the bed-of-nails is contracted out, it often takes two days to get the functional specification document, documentation and the necessary signatures. Delivery times for a bed-of-nails are typically 3–4 weeks. A lot of time is needed for communication between the customer and the manufacturer of the bed-of-nails.
Our new test fixture production system AAE-CNC 2 enables you to produce a complete in-circuit test fixturing incl. wiring within half a day. You drill the exchange plates of the exchange fixtures for loaded electronic PCBs and place the contact pins automatically. Constructing, drilling and placing the contact pins on the bed-of-nails with typically 10–20 µ accuracy incl. wiring takes a few hours only. The bed-of-nails for the contact pins, reference pins, placing devices, maybe IC-Open-probes and polarity probes are drilled out of the data which were calculated and selected from the Gerber files. No offset or other special entries are required when the test fixture production system is set up. The contact pins incl. receptacle are pressed in very accurately with a special tool which is also controlled by the CNC-machine. Depending on the D-codes the system selects contact pins with different plunger tips from the bipartite magazine. Then comes the wire wrap-wiring. For that there are multi-way connectors which are already wrapped so that only the contact pins must be wired. In this way, a test fixture incl. the calculation times for the Gerber files can be finished in about 4 to 6 hours.

With two to three fixtures a year, the investment will be repaid within one year. With such low cost for a bed-of-nails (often less than 500 Euro original costs) bed-of-nails fixtures are cost-effective even for small series.

Open Database Connectivity - ODBC-Interface for ATS-KMFT 670, ATS-UKMFT 645 and ATS-UKMFT 625

Via this interface the REINHARDT-test system is integrated in quality management or production procedures with data base management. The data transfer can be configured so that the data base management system can process the information for quality management, statistics, etc.
The required data base is selected with the ODBC-interface and a connection text is generated. In the test run, this text is used for selecting the data base where the data are stored. Then the table is chosen which stores the data. For that you may use an existing table or generate a new one. When the table is selected, its fields are listed so that only the data sources must be assigned. If the name of a table which does not yet exist is entered, the required fields must be selected and connected to the data sources.

Quality Management - Reference Test

More often, reference tests are specified in testing requirements. Based on a test item which is known to be good, the function of the test system and the fixture must be checked and documented after a specified number of test runs or after a specified time interval. As soon as the number of test runs or the time interval is reached, the test system is blocked and testing can only continue after the reference test.

RMX 96 - Measuring Matrix Board with 96 Measuring Matrix Channels

Because of new technologies and miniaturised relays we could raise the number of Incircuit- and Function measuring channels of the measuring matrix board to 96 channels. Durability and contingency reserves made us again decide on the more expensive relay matrix instead of a semi-conductor matrix: The relay matrix guarantees higher interference resistance and stability in the harsh test department than a semi-conductor matrix. Unwantedly high voltages arise inevitably in the Incircuit and Functional test. The basic capacity of a relay matrix is lower than that of a semi-conductor matrix. This is advantageous when low capacitances are measured and improves the test speed.

The new RMX 96 measuring matrix board has the same features as its predecessor RMX 32/64 with 64 channels. We have allocated the interface in such a way that backwards compatibility is guaranteed. This board can be used in all current ATS-KMFT 670, ATS-UKMFT 645 and ATS-UKMFT 625 systems. All matrix boards have electronic board recognition so that the system recognises how many boards there are and their positions.

The used high-speed-relays allow switching voltages up to 200 V, 0.5 A maximum current at max. 10 VA. Each channel of the RMX 96 measuring matrix board can be used as High-channel, as Low-channel or as Guard channel.

Good-Fault Box

PCBs which are tested faulty must in no case get together with PCBs which are tested good so that only faultless PCBs are forwarded to production or sales.

We have therefore developed two boxes sized 615 x 495 x 200 mm which are controlled by the test computer via USB-interface. If a PCB is tested good, the Good-test box opens while the box for faulty PCBs remains closed. The test system can continue testing if you deposit the PCB and close the lid. If the lid is not closed, the test procedure is clocked and a message shows that the lid was not closed. For a faulty PCB, the „Fault“-box opens automatically and when the PCB is desposited and the lid closed, testing can be continued. The test boxes hold plastic trays sized 600 x 400 x 140 mm, which are marked with the type „good“ or „fault“. When one of the test boxes is filled, the complete test box is opened in order to remove the plastic tray and to insert an empty one. Additional good-fault-boxes help binning products. Max. 5 good-fault-boxes can be controlled.
In this way, the successfully tested electronic PCBs can be deposited with as much security as possible. This facility was mainly constructed for testing electronic PCBs, but it can as well be used for any quality tests in the electronics, cable or mechanical range.

Eagle-Interface for Data Transfer for REINHARDT Test Systems

For the widely used cost-effective Eagle CAD-system for developping and designing PCBs REINHARDT has developed a comfortable interface. Up to now, Eagle-data had to be adapted manually for use in the test system-software. This software tool helps to do this fast and cost-effectively: The software generates a bill of materials and Gerber data which can be displayed. This information is used for generating the graphical data for the display of fault location and the finished framework for the Incircuit test program. After the converted data are imported into the test system software only the automated autolearn tools such as e.g. for pin contact test, shorts and isolation test and the APG in the component editor must be activated. The procedure of the Eagle-data conversion is widely automatic and is finished in a few minutes.

New Electronic Component Counter ZE 300 Uses Laser Technology

Since 1977 REINHARDT System- und Messelectronic GmbH have delivered component counters for axial, radial, wired and SMT bandoliered components. Missing components can bring about high cost. Therefore they must be counted, be it for compiling production lots or the annual stock taking, in stock-receipt or goods outwards for checking numbers, from the producer as well as from the distributor.

Instead of the widely used photoelectric barrier technology a new measuring technology is used in the new electronic component counter ZE 300: The laser technology offers a measuring beam with higher energy density and therefore more precise counting and faster counting speed. The ZE 300 component counter is microprocessor-controlled. There are neither any miscounts in counting forwards or backwards nor if more than 100,000 components are counted. It can be used for axial, radial up to 16 component pins and tape widths up to 70 mm or 75 mm and, needless to say, SMT up to 8 mm to 60 mm width. The ZE 300 can be expanded with an optional tape winder for counting the typical 7 ", 13 " and 22 " component rolls, but as well rolls up to 680 mm diameter. Numbers can be pre-selected or can be set by the computer via an RS232-interface. There is an acoustic and graphical display on the tilting LCD-display when the selected number is reached. The ZE 300 electronic counter has an extremely robust steel-plate housing. There is an integrated, chargeable accumulator so that the ZE 300 can also be used up to 8 hours away from mains supply. It therefore offers very high flexibility.
