How I Fixed My Cracked Circuit Board with Epoxy

circuit boards could use some repairs every now and then.


Sometimes we can crack due to pressure. This time, my PC motherboard cracked due to heat. I discovered that there weren’t enough fans in my computer to cool the circuit board properly and it split from the excessive thermal stress. Partly because I like fixing electronics for fun, and partly because I’m not rolling around in money to buy a new one, I decided to get a little crafty and repair the broken board using Super Glue’s Quick Setting Epoxy.

The Motherboard of All Repairs

To begin my repair, I made sure my workspace was clean and dry. Next, I took the blister the epoxy came in and with one push, the resin and the hardener came out equally. I mixed the resin and the hardener and applied the epoxy to my cracked circuit, smearing the adhesive gently into the crack. I took special care not to damage the circuit board traces.

Keeping the motherboard tight, I was impressed by how quickly the epoxy set, taking only about 4-6 minutes. I made a few other technical adjustments, and also added additional fans to cool my computer sufficiently this time. But before I knew it, my circuit board was back, without the crack, and working its communication magic once more.
