ANALYST EMS+FT 12KN ICT/FUNCTIONAL TEST SYSTEM

PRODUCT DESCRIPTION

The CheckSum Analyst ems+ft extends the testing power of the Analyst ems with an integrated functional test subsystem that includes flexible stimulus, measurement, and switching capabilities. It combines in-circuit test (ICT) with power-up functional test to provide high fault coverage in a single, low-cost platform that can be customized by the user to fit a variety of test requirements.

Including industry-unique features such as 250VAC switching and a fully integrated DMM, function generator and counter-timer, as well as available relay switching in 50 point increments, the Analyst ems+ft meets a broad range of functional test requirements from straightforward power up “board alive” tests to extensive functional test sequences.

A typical test sequence on the Analyst ems+ft would proceed as follows:

Power-off in-circuit test (ICT). Typically, test programs are written such that the test is aborted if any power-off faults are detected.

Apply board power and check critical voltage points including behavior of powered components such as operational amplifiers.

Perform more extensive functional testing such as checking input/output parameters.

Solid-state switching in 200-point increments and 50-point relay switch matrix cards may be mixed in any combination.

Circuits with voltages up to about ±12V will typically employ solid-state switching and voltages up to 250Vp-p are accommodated by relay switching. When greater than 40 volts is present at the UUT during test, the test fixture should be designed with safety shielding and operator interlocks to help prevent the operator from coming in contact with the signals.

In most cases functional test can be performed using the same test fixture as the in-circuit test so that minimal time is spent transferring, loading and unloading the UUT.

The Analyst ems+ft includes an additional 19-inch rack space, allowing the addition of off-the-shelf measurement/stimulus instruments or programmable power supplies to meet special requirements.

CONFIGURATION

Mechanical Format

The Analyst ems+ft 12KN includes the 12KN dual-level, long-travel pneumatic fixture press built into a rack-cabinet. This unit can be installed on your factory floor, and is ready for use once connected to standard compressed air and a 220VAC outlet. The standard configuration is complete for most testing operations. It requires only one load/unload cycle per test, with no lids or doors for the operator to manipulate between tests. CheckSum can ship the system to you complete with a ready-to-use test fixture and test program for one or more of your UUTs. You can use CheckSum’s fixturing division to handle all of your fixturing and programming needs; or you can modify or add UUTs yourself or with the use of third-parties.

 

Fixture Kits

The optional CheckSum fixture kits; KIT28, KIT20², KIT2KN-QC², or KIT1000-QC² can minimize your recurring costs. The fixtures include handles to make storage and moving easy. Installing the fixture kit simply involves sliding the top and base into place. The bottom assembly includes a fiberglass (G-10 / FR4) probe plate with a fixture interface section and pan covering the wiring.

 

The top assembly is a clear polycarbonate plate that is used with pressure rods to press the UUT down onto the spring-probes. The top assembly can be machined and milled. The front of the UUT is accessible during test time for adjustment access.

 

To run a test, the operator places the UUT on the fixture guide pins, then presses the start test button. Once the test is completed, the system displays the results and the fixture top automatically rises so the UUT can be removed.

PRODUCT DESCRIPTION

Designed for testing all types of circuit assemblies the CheckSum Analyst ils has all the features of the Analyst ems, but in a package with an integrated high-speed board handler for use in an automated production and test line. The CheckSum Analyst ils combines manufacturing process testing with TestJet Technology for high fault coverage in circuit test of a single assembly or a panel of multiple assemblies in minimum time with maximum fault coverage.

Providing features such as periodic sampling of UUTs passing down the line and automated recompression of probes and/or automatic retesting on failures, the Analyst ils meets sophisticated testing needs.

The Analyst ils performs effective power-down testing for most analog or digital assemblies being manufactured today quickly and easily testing through-hole and SMT circuit board assemblies for common manufacturing defects such as incorrect, missing or misoriented components, and opens and shorts. Equipped standard with TestJet Technology, Analyst can identify opens in and around most analog and digital IC packages. These faults comprise the vast majority of problems encountered in the today’s electronics manufacturing environment.

The optional power-up functional test capability is ideally suited for lower frequency analog assemblies with some digital content.

The Analyst ils tests the entire unit-under-test (UUT) and individual components without power applied to the UUT. Using sophisticated measurement techniques such as DC or complex-impedance measurements in conjunction with multi-point guarding, ICT systems quickly and accurately measure continuity, capacitors, resistors, inductors, voltages, semiconductor junction voltages, and SMT connections for opens. By finding the majority of faults while the UUT is in the safe unpowered mode, together with very specific fault diagnostic messages, faulty UUTs can be repaired quickly.

PRODUCT DESCRIPTION

The Analyst ems Low-Cost In Circuit Test (ICT) System provides the capability to quickly and easily test assemblies for common manufacturing defects such as incorrect, missing or misoriented components, and opens and shorts. These faults comprise the vast majority of problems encountered in the typical manufacturing flow. ICT systems can quickly and accurately measure continuity, capacitors, resistors, inductors, voltages, semiconductor junction voltages, and SMT connections for opens. With these basic tools, ICTs can find most faults in analog or digital assemblies before board power-up.

The CheckSum Analyst ems is designed for testing all types of circuit assemblies. The System combines manufacturing process testing with TestJet Technology to test a single assembly or a panel of multiple assemblies.

The Analyst ems tests the entire unit-under-test (UUT) and individual components without power applied. Using sophisticated measurement techniques such as DC or complex-impedance measurements in conjunction with multi-point guarding, it provides the capability to find the majority of faults such as shorts, opens and wrong or incorrectly installed components. By finding the majority of faults while the UUT is in the safe unpowered mode, and with very specific fault diagnostic messages, faulty UUTs can be repaired quickly.

Station Configuration

The station configuration software is used to set up the station’s software and hardware environment.

To manage the system hardware, the station configuration software provides for specification of the hardware configuration in the system and includes a comprehensive self-test facility for each module. The self-test software checks each module for proper operation. In many cases, the system also performs self-calibration of modules against internal standards. This data is then saved to the system disk for future use. If external traceability is necessary in your installation, the system can be checked against an external calibration module (included), and optional functional test electronics can be calibrated against typical external standards using included interactive software.

The login capability can be enabled to allow users to login to the system. This can be used so that reports and internal SPC logs contain the operator name. Optionally, passwords can be assigned for each user. Each user can be assigned privileges, to the level of each individual menu selection in the system.

Reporting capabilities can be configured to meet a wide variety of needs. Test reports can be output on demand, always, or on failure only. The reports can contain all results, or just results for failed steps. The header format, and amount and order of information for each step can be specified, as well as the destination device (e.g., which printer, or to the CRT). Test program reports can also be configured to include or exclude specific data. SPC data-logging can be disabled, or enabled for pass-only steps, pass and fail steps, or just test summary information.
