15 years ago I was working at a place that I had many duties. We would make board like those. I would drill, etch, reflow solder, and electroplating at time. I would also inspect, test, and repair shorts. I didn't have the manual dexterity to repair open because it takes a gift to repair super small voids in the circuit from bad screening or the thin lines being over-etched. Some boards are so badly balance with super wide lines and just tiny ones you have to do a two part etch so you tape over "Mask" the thin ones then mostly etch around the large ones then take of the tape for doing the final etching. Also had much bigger parts than on that project. on my tester the risk chips were the size of a small box of matches, each one was 256K memory. But that machine was early 80's so we were lucky it still worked at all. Mostly electrical faults since the mechanics were pneumatic so that was a simple adjustment. Must have stood for a year in total on that machine testing like 200k boards over my years there. Must have make 5k fixtures for testing also. Was like a game to me. I got that testing unit productivity up by 5x with my changes. My boss was pissed I was spending all that time not working on product till he realized that something that took 4hr I finished in 1 and then in the other 3 hrs built the next 5 fixtures for tomorrow. It was all common sense shit because people were lazy finding the test fixture to over an hour since they'd just stack them in a random box. My fixing the storage I could find one in 2 minutes flat.
