I have listed it on E-bay but what grade would this be if I scrapped it
It was removed from a large industrial laser
Any help or info appreciated
Looks like lowgrade in my book.
No offense but the board is much to thick to be lowgrade and has to many silver connectors...........I may be wrong but I think it is at least mid-grade
I don't believe thickness has anything to do with grade except for when it is something like a server board with thicker gold trace.
Those boards are translucent and you can see exactly where the traces are - and there aren't many of them. That coupled with the large amount of weight in capacitors and the fuse relay and no IC chips would lead me to call this low grade.
If those are gold connectors on the edge, I would break those off, but that's it.
I'm suprised but mabye you guys are right....They have a date of 1981 stamped on them and came out of industrial laser....figured they would be better
Just because a board is old doesnt mean that it needed Pms to protect it. The lack of traces gave it away and unless you did a test on the connectors it would be low grade. most the time its just solder. Only in gold plating is board thickness a factor.
I had a couple of small ones with gold traces and pins and my last buyer called them low grade simply because they were tan colored. So I threw them back in the car and brought them home for now. No way they were gonna pay me .12-15 lb for gold pins and traces.Quote:

I'm gonna find a buyer (small refiner) for the odd stuff like that and the gold legged transistors and all the gold film from the printers. Almost have a small tote full, (cross fingers)Quote:

I brake down alot of printers and I find film that is like paper that has mostly copper but looks to have gold fingers were it plugs into aa circuit board.
I would call it low grade too, most of the weight are the capacitors. I would break off and gold pins ect and sell the rest as low grade.
I say low grade. From a designer point of view, it looks double sided very low component density, as opposed to multi layer high density interconnect. I would try hamfests. Most of the older guys like through hole components more than surface mount.
Well I have several watchers on these boards on e-bay so I hope they sell there for more than scrap..........I have several more inside the control panels of this laser so I'm hoping I can make a little money on this thing..(I paid a little to much for it) LOL..........$150 is my initial investment.......I sold the transformers for $30, the #1 copper out of it for $34 so far so I have already made almost 1/2 my money back......I also have the motor I pulled from it on ebay so we'll see
