Perfect pink PCBs

A project log for Light level geolocator

If you have a lot of time, you can decide your position on Earth just using watches and eyes. Or RTC and LDR.

I hope @oshpark will not mind abusing their motto for the PCBs not made by them, but the color is a bit similar.

I asked friend of mine to produce a few boards for me, as I know he is making some PCBs for himself, occasionally. He agreed and asked me what color of soldermask I want - I didn't care much, answering - "I don't know, let it be pink.". - "Say no more."

Searching for proper shade of the pink color.

Here it is:

Already drilled and etched PCB is covered by pink soldermask

Soldermask etched away

White on pink, nice combo

Separated forever

And detail to my little PCBs

One PCB populated

The red and black wires are for powering the board during development.

LCD works!

So far so good, now I'm going to transcribe the sunrise/sunset detection algorithms, as well as reverse sunrise equation for use with the MCU, do some minor tasks, like user interface and logging - and LLG is done!

It looks great, I also plan to make a pink solder mask PCB. How do you adjust the color? Are there detailed steps?

Do you know what material the soldermask is?  Not necessarily the pink, beautiful as it is, but just what kind of paint or whatever it is?

I'm going to try milling some PCBs and wonder about adding a soldermask to them.

It is classic two part solder mask (with hardener too), bought locally from here There are links to datasheets, where you can find a lot of Czech text with some english names of the products, like

CAWN1290 Imagecure XV501T-4 Gloss Screen Dark Green Resist

CAWN1292 Imagecure XV501T-4 Screen Clear Hardener


On ebay you can find some one-part solder mask substances, like or dry film solder masks but those do not have such as mechanical/thermal resistance as standard two part resist.

these are so pretty!

Pretty! Next time add some glitter!

We need a script that randomly adds vias to simulate glitter...
