The Zehntel Automatic Test Equipment was an In Circuit Component Tester using Hewlett Packard 9000 series desktop computer running Hewlett-
We were testing printed circuit board which were made in the factory and were checking for manufacturing defects. Each PCB type had an individual test interface box that connected the Zehntel’s test functions to each ‘node’ on the UUT PCB. This allowed the Zehntel to ‘look into’ the PCB and check that all the correct components were in the correct positions, the correct way around. This would all be done without the PCB being powered up. If ‘powered up’ tests were required, this could be added to the test routine. On average the Zehntel could check a PCB with 200 components in about one minute.
At various times we were in a position to take in sub-
After some reorganisation of departments and workloads I was taken in by the Test methods Department and went on to design test-
We had started, initially with a VAX-
The IBM PC had arrived. I was quick on the uptake with this and very quickly learned how to use and program it. I used to run informal classes on the DOS operating system and how to tweak DOS to get the best out of the PCs.
This led me to starting my own business.
