in-line automated electronics tester

A Tester in Every Line

Why is it the entire electronics assembly line is automated until test?  There are exceptions and it is becoming more automated, but why aren’t in-line testers the norm? The reason is speed.  Test times for PCBAs are typically much longer than any other single manufacturing step.  That time is called “Takt Time”, the time between […]

Piezo Sensor Project

When an internationally known producer of sensors came to CheckSum with a challenging ICT test requirement, we were ready.  The company produces sensors of all kinds but this particular product does not lend itself to traditional bed-of-nails testing. The product is a piezoelectric film sensor, produced on sheets just 32 micrometres thick (less than .002”) […]

How Can CheckSum Be So Much Faster? – Video

We developed this video for APEX 2019 to highlight the differences between our test process and traditional test processes. The CheckSum Parallel Technology paired up with our powerful V12 and Dual and Quad Core ICT delivers many fold speed increases especially for small boards manufactured in panels. This process reduces or eliminates human handling, drives […]
