DorkbotPDX PCB Order Review

I ordered the motor controller and temperature sensor boards from Laen’s PCB batch service. He charges a flat rate of $5.00 per square inch rounded down to the nearest hundredth of an inch, no setup or shipping charges, and you get three copies of each PCB you order. If you have a small board, or need more than one copy of a board, then it is definitely better priced than BatchPCB. ¬†Orders are sent in every two weeks, and there is a two week turn time. If you’re lucky, you only have to wait two weeks to get your boards, otherwise it could take up to a month. Another plus is that the PCBs are manufactured¬†in the US. The minimum specifications are 6 mil for trace widths and spacing, and 13 mil drill size, slightly ‘better’ than BatchPCB.

My first set of boards turned out great, if you ignore my own design mistakes. I rushed to make the order deadline, and overlooked several mistakes. I missed a power connection to one chip and even had a DC barrel connection oriented incorrectly. These are both issues that would have been caught if I gave the schematics a second look. Thankfully, they are both easily corrected with a knife and drill.
