Step by step guide to repairing circuit boards
Yes, I know, my hands are shaky.
I didn't say it in the video, but the epoxy doesn't have to be Super Glue brand. There are several different brands of 2 part plastic bonder epoxy. Any of them will do. Of course make sure the power is removed and all capacitors are discharged.
<p>my phone motherboard broke in half at the end any tips plz</p>
<p>kk cheers.</p>
<p>could you fill the crack with solder so a connection is meade ?. because the chip is cracked but into two seperate pieces.</p>
No
<p>do you know how to fix a cracked chip instead of replaceing it.</p>
<p>Are you saying you have a cracked IC (integrated circuit) like in the picture?<br>If it's still functional, a little 2-part epoxy can be used to strengthen it and prevent flexing. If it doesn't work, there is really no way to fix it. It would have to be replaced with an equivalent. </p>

Superb! I was busy resizing a keyboard circuitboard for a project but did not know how to put the pieces back together after cutting it to size. I tried the epoxy and it works great! it's quite strong too, thanx for the tip dude!
I had once in my professional life met one broken motherboard from a unique industrial robotic system. Due to extended vibrations years by years that motherboard cracked in the middle like a plastic toy!!!. Was impossible to find a substitute because the whole system was made from a company far closed. So what i did: 1st I rejoin the 2 parts with staples in some points that didn't influent the circuit. I drill some tiny holes and i placed the staples. Some of them i isolated by dying them in wax (properly made it for electronic components) 2nd I pass all the broken joints and circuit paths with a small quantity of solder. If I have to do with multiple joints i use a cable and so! So far after 5 years that robotic machine works fine. I put it in addition in an antiviibrating base and everything is perfect.. Of course every one has different perspective of the same issue, but that was mine experience.
You must've done a good job if it's been working for 5 years! I do recommend using epoxy though since it's the material which most boards are made from. In a board, the epoxy is strengthened by fiberglass, so for extra strength, a little glass mat should do the trick.
