He’s put that PCB on GitHub if you’re interested. To start off, JLBPCB is the Chinese clearing house of choice for [Jeremy], and they quoted a very cheap $7.10 for 20 boards.

1. Bob Pease made this prototype of the Philbrick P45 op amp back in the 1960s. The top-side of the board looks like a production PCB.

Grinding out copper is one way to create a printed circuit board, and low-cost CNC milling machines have improved to the point where it’s possible for many.

Prototype board for microcontroller with LCD Save time if you build a prototype with microcontroller and LCD. Because at least a part of such a circuit is the same you can often use the same PCB.

But if your goal is to prototype something and the PCB is just a means to an end, dump that ferric chloride, save the end mill, and find a board house. You’ll be glad you did.

I never find it easy to build op-amp prototypes using surface mount components. One can buy an adapter PCB that converts SM to through hole pins compatible with 0.1inch breadboards or prototype boards ...

I just got an email from Gail Balderas at Royal Circuits about their prototype PCB services. They are running a holiday special we can all appreciate: five 2-sided boards for $150 and that on a 3-day ...
