I take even all in one printers apart to gather chips for processing, which is basically loosing game, but once a while, I get rewarded with north/south bridge. The other value I collect is optical bar with linear ccd, right under the scanner glass. It moves there and back while scanning image. It is about 9" x 1/2" peace of circuit board, with exposed linear ccd almost as long as the board, some circuitry and between 100 and 200 gold bonding wires, depends on the model. It is mounted underneath black plastic with linear lens and illuminator. I have more than 200 of them, but not sure how to process them. The only process I could think of is HCl first, to get rid of tin and then AP to free ccd chips with bonding wires. I searched this forum some time back with very limited results. Any suggestions? Thanks.
