Testing with a massively parallel board test system

Testing for high-volume manufacturing boards requires a printed circuit board (PCB) panelization technique and a parallel test system that enables operators to test multiple boards. This technique fits smaller, less complex boards into a manageable panel size that is more cost-effective and reduces loading time and test time significantly. In addition, massively parallel testing enables simultaneous testing of multiple boards.

This reduces the need for additional fixtures, test operators, and floor space, ultimately saving costs and improving production scalability. Apart from in-circuit testing (ICT), manufacturers require in-system programming with a read / write capability to perform flash programming. The system should also support the integration of functional test instruments and power systems to meet various test requirements and to keep up with high production volumes.

High-volume PCBA test solution

High-volume printed circuit board assembly (PCBA) testing requires a test system that can conduct ICT, flash programming, and functional testing to keep up with high production volumes. The Keysight massively parallel board test system meets the challenges of high-volume manufacturing and testing, offering flexible scalability and configuration, the ability to maximize the test efficiency of various PCB layouts, and enables the testing of multiple (up to 20 boards) devices under tests (DUTs) simultaneously. The system can also perform unpowered and vectorless tests for component testing. By feeding the test system data into the Keysight manufacturing process software, manufacturers can obtain actionable insights to identify the root causes of functional test failures and scrap issues, resulting in improved efficiency.
