Eli, a great part of the value of this thread is that we can meet and kick ideas and info around. GRNO itself is out of our control and is run by BC, but we can at least help ourselves and each other by discussing GRNO and providing helpful background. 20 years ago at the Avantek startup, the results of my efforts were combined with other product lines into one profit center. My end of it had absolutely no glamor for engineers because other products sold for many thousands each and took tremendous skill and knowledge to design and produce. But if one wandered out on the manufacturing floor, one would see 20 super technicians shipping the same dollar amount of glamor product that 6 testers shipped of my stuff. And my testers were minimum wage types hired off the street. Huge difference in cost. But I discovered by snooping that the test yields of my designs in production really stank. That was because the automated equipment that assembled and hooked up my circuits wasn't perfect in those days, and technicians needed to trouble shoot. But my minimum wage testers didn't use my circuit alignment procedures because they didn't understand them. So I volunteered to set a training class for my testers. After hours I gave them a handout and projected the same picture on a screen. The screen showed an assembly diagram along side a schematic. I pointed to each element on the schematic and pointed out what that looked like when they looked at the circuit under their microscopes. I told them to jam a sewing needle into the end of a toothpick, cut the needle off so only a tiny metal stub protruded from the toothpick, and poke at various places on the circuit while watching what happens on their oscilloscope screens. Then by following my test procedures, my 6 minimum wage testers were miraculously converted into super techs and my yield went to 97%. My product lines soon had their own profit center. There are people who read this stuff on here that never post, but who learn the same as any of us. The more we learn of the nitty gritty details of our investments, the better we feel about the choices we make. That is one way we can control and shape our own destinies. Charles
