After finally finding time, if not all the right parts, to start soldering the preamp board (see previous post) there are a couple of quick observations to fill the time until the next post, which will have files included with it:
- The resistor and capacitor pads in 0805 SMD cases look too small to solder on, but are actually not too bad. They’re a little less forgiving than the default Eagle pads, overall though that’s one less thing to worry about. I haven’t tried the SSOP packages yet, but they look substantially more tricky.
- On closer inspection, ie actually soldering on the boards, the quality of the BatchPCB boards has dropped significantly. The silkscreen is fuzzy and a number of the drill holes are not centered. For the time being, I will move over to Dorkbot PDX for PCBs as the quality is excellent, and you get the bonus of 3 boards instead of 1 for a similar price and usually faster turn around. That that multiplies the number of potential coasters by 3 is another matter..!
That’s all for now, and hopefully I’ll be able to finish up the project in the next couple of weeks and post up some more information and files.
