Well, here’s what you need to start.

- Solder paste for the LEDs: https://www.banggood.com/XG-Z40-10cc-Syringe-Solder-Paste-Flux-Paste-Sn63Pb37-25-45um-p-973158.html

- Solder paste for the springs and electronic pads: 2 Stück 50 g bleifreie Niedrigtemperatur-Schmelzpunkt 138 Grad Lötpaste Sale - Banggood Deutschland sold out-arrival notice-arrival notice

Keep these pastes inside of a ziploc bag in the fridge.

I guess you already have a good soldering iron, along with appropriate tips, correct?

- Any kind of temperature adjustable hotplate

And that’s about it.

There are also some other things you can get, but just PM me for more info. :slight_smile:
