DiscFerret -- PCBs have arrived

... Well, actually, they arrived at the beginning of last week and I didn't finish checking them against the netlist until today. My excuse is that my notes are all on Cougar (my laptop), which is currently refusing to boot without segfaulting in the kernel. Rather than deal with ASUS support, I replaced it -- the replacement (an MSI U230 named Ryoko) is far better behaved :) Scanned images: Top: http://www.discferret.com/images/discferret-pcb-top.jpg Bottom: http://www.discferret.com/images/discferret-pcb-bot.jpg They seem to have come out OK. The solder mask is a little discoloured around some of the thinner tracks, but that's a cosmetic issue. It still resists solder, thus it's OK :) For the pathologically curious: Substrate -- FR4 fiberglass, 1.6mm Track layers -- two copper, 1oz Layer stacking -- BOTTOM COPPER, FR4, TOP COPPER, TOP OVERLAY Surface finish -- looks like lead-free HASL or roller-tin. It's certainly not immersion tin or silver, the pads have roller marks on them. It turns out I hammed the entry of the order, and managed to order two sets of three boards, leaving me with six PCBs in total, and an additional 130 Euro bill. Ick. I'm still short of some parts (notably: the USB ESD suppressor chip, some pin headers, 7-pin SIL resistor packs and 10nF 0603 decoupling capacitors). A trip to the Farnell trade counter is being meticulously planned, as long as I can get someone to hang around the house and wait for my Rapid order to arrive (mouse microswitches... Logitech should be shot for using those nasty Omron things). Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
