Rivets/eyelets for PCB repair
« on: April 11, 2021, 06:59:20 pm »
Hello!

I am looking for PCB eyelets/rivets for PCB repair, but in local online and global stores (like Aliexpress) I see many offers, but only made of brass, not a clean copper.

https://pl.aliexpress.com/af/rivet-pcb-copper.html?trafficChannel=af&d=y&CatId=0&SearchText=rivet+pcb+copper&ltype=affiliate&SortType=price_asc&groupsort=1&page=1

Anyone have a nice store with real copper eyelets?:)

This is what I use and links therein.  The site I bought from originally is no longer alive. For me, 100 seems to be a lifetime supply.  They can be set with home made tools, if you have a lathe.

Edt:  Here's a link to Circuit Medic, which used to and maybe still does supply them:

Edit #2:

Will a piece of tinned copper wire, like 24 awg to 30 awg work?

Rembrandt electronics in the Netherlands is selling copper eyelets on Ebay.  You can get a nice assortment of various sizes for around $22 USD.  They also sell small lots of one size.  Just search for TH eyelets

Why would you want them made of copper? It corrodes in air and makes soldering harder. I've only ever seen PCB eyelets made of brass, which seems to stay solderable forever.
Unless you're repairing the drive electronics of a Tesla, I doubt the difference in resistance makes a difference.
