[chbot] Costs of custom PCBs just keeps dropping....

[Quentin McDonald]

Hi Mark,

In fairness this was some time ago and I'm sure my technique was relatively
poor (more heat, more heat!). If I remember correctly it was a DIP16 socket
I'd inserted the wrong way around. Yes... I know it doesn't really matter
but I was having a compulsive moment.

The topic of Chinese manufactures did come up on another mailing list I
subscribe to recently. Bottom line appeared to be that if you do enough
boards eventually you'll get something weird, missing copper or poorly
plated holes or some other random failure. In general however it sounds
like design failures outnumber manufacturing ones by several orders of
magnitude. My one attempt to go straight to PCB reminded me of how handy
the breadboards are...
