All correct except 8 8 if the shields are gold flashed don’t remove them. If that’s your flash find a new phone or camera, meany. Lol
9, this is a tuff one. As Chris said there’s both art and science in grading at the commercial level. The ISO markings tell me this is a flat board, which is wrong just from my own experience so this is a Chinese knockoff board. As such we are faced with pure experience. The IC population isn’t there for peripheral. Nor is the copper content. With switches and relays plus the base components I’m guessing around 5-8 ounces of copper here. The flashing isn’t gold. Based on experience and looking at the photo on an HDR 12-bit display. I can see the lines in the sheen. Any good scam can turn copper into ‘gold’ by adding tin and zinc. The more tin the golder copper looks. Zinc stabilises rf leakage. For reasons other than what CC was looking at I’m calling midgrade. And only just barely. Chris’s people don’t dive as deep into boards as I do. I’d be about a third the rate myself.
