Electronics: cap-fun PCB fabrication results

I used JLCPCB to fabricate my cap-fun circuit (see part 1). It was under $20 including delivery, for 75 copies of this small PCB (4 x 4 cm).

And I’m glad to say the circuit works. Here it is with components soldered:

I’m happy with the quality.

I got it printed with 3 x 5 items per sheet, with easy-to-snap V-cut scoring:¹

A pretty good experience overall. Their website is decently made and I was surprised by how much feedback I got during the fabrication:

And I appreciated how the detailed delivery updates came directly through the JLCPCB site itself:

Thoughts on seeing the printed PCB

• the soldering pads should be bigger, especially for the resistors, given that this is an educational board. This is just a matter of footprint choice during layout
• be nice if the board had a shortened link to the blog post printed on it
• I done goofed and the 1000uF marking on the cap ended up on the wrong layer somehow, so it’s not visible on the board
