In Circuit Test Development

In-circuit testing is an electrical inspection tool used to check that a printed circuit board has been built correctly.  It can ensure that all the testable components have been fitted and are the correct value, tolerance, and orientation. 

Abtest Limited offers the complete package for GenRad and Teradyne 1800 In-Circuit testing.

Experience

The engineers at Abtest Limited have over 10 years experience in developing GenRad and Teradyne 1800 In-Circuit test packages for high volume production environments.

Reliability & Safety

Our fixtures and software are designed to offer reliability, repeatability and safety in high volume production environments.

Turnkey Packages

We provide complete solutions for In-Circuit testing on GenRad 227X and 228X testers, as well as the Teradyne 1800 platform.

Platforms

Abtest Limited has the ability to develop In-circuit test programs for all GenRad 227X, 228X and Teradyne 1800 testers.  We have off-line development  capability using MVAX, UNIX and WindowsNT workstations.

Technical Information

Fixturing

We design and manufacture precision tests jigs and fixtures for production testing of electronic printed circuit boards. Our package includes: open top hat assembly incorporating a cover for operator safety, risk assessment report, purpose designed discharge and power supply status board, and spares kit.  Abtest Limited also offer customised fixtures to suit individual needs. These can be configured to incorporate, Vacuum, Pneumatic, Single Sided/Double Sided, Single and Dual Well configuration.

Programme Development

The test programs are written in-house to meet your specification and requirement using MVAX, UNIX and Windows NT work station offline development tools.
We offer individual device modeling to improve the test coverage of your product .  If access for test is a problem, we offer the facility of cluster testing components.

Computer Aided Design (CAD) Data

Abtest Limited offers the facility of being able to process CAD data files if available, by using a CAD interface software package such as CBTEST or C-LINK. This enables the engineers to produce accurate test programmes and fixturing data with reduced lead times. 

Opens Xpress

Abtest Limited caters for Opens Xpress hardware and software. We manufacture custom Opens Xpress probes for our fixtures, and include Opens Xpress tests in software.

Panel Test

We have the facility to develop programs for paneled boards using the GenRad Panel Test Software.

Installation

During installation it is our policy to run a batch of production boards through your tester to ensure stability of the fixture and test program.

Documentation

Test package documentation will be supplied with the fixture and test program. This will contain testability reports giving an overall percentage of test coverage, fixture specifications, wiring lists, schematics, parts lists of any hardware inside the fixture, audit and risk assessment reports. The documentation can also include graphical representations of the fixture layout and UUT layout - eg a picture of your PCB showing components that require visual inspection.

On-Site Support

Abtest Limited can provide a test engineer at your site for engineering support such as implementing ECOs.
