Hey everyone,
Every now and then a SMC dies and I'll have to steal one from a dead motherboard and this requires reballing of the chip in pretty much all cases.
Right now I got a basic reballing 'station', but even with the screws to the maximum the SMC isn't fully fitting and still slightly lose.
This is only a small issue, the biggest issue I'm having is that with solder paste, the flux dries up while heating the paste which ends up making the SMC stick to the stencil, ruining the reballing job in most cases. Or the balls end up floating inside the stencil, not touching the SMC so the balls are not being applied to the SMC. To make it even more of a chaos every now and then balls just merge from underneath the stencil with each other. If after two or three times I finally get it right, I have to pray I didn't fry the SMC and have to start over again.
Short story: My reballing is a mess
I was wondering if anyone had recommended tools, temperature settings and paste to use?
I don't even mind paying good cash for a amazing chip and stencil holder because its such a pain in the butt right now.
Cheers
