We bought a Ersa rework station (IR technology) recently and we found in trouble when having to replace BGA with metal heat sink cover. I am affraid that we will probably have to invest money again in a convection rework system. Does someone can refe

Forced gas (hot air or N2 according to solder paste or flux) will be the solution. To rework Ceramic (Aluminum lid Heat Sink)BGA (32 mm square ) or Ceramic Colum Grid Array C-CGA 1,25 and 1,00 mm colum (pitch 42,5mm square), also them capped with a

To be precise, the component is a Xilinx Virtex platform FPGA with 1152 balls. We also assemble some DSPs up to 1000 balls with metal cover. At best, we can remove the components but it is almost impossible to find a working solder profile using IR.

We received a contract job that requires a board with a heat sink integrated (glued onto the top layer) and the heat sink needs to be powder coated. So I need a board vendor that can provide: Multilayer board fab, Heat sink fabrication, Powder coat t

That might be tough. Board houses typically stick to boards. You might find a board house that already works with a vendor that can supply Powder coated heatsinks, and the Board House might integrate for you, but it doesn't sound like one stop sh

Yes, I agree that finding a vendor that can do fabrication plus the metalwork may be difficult. I am open to those board vendors who have relationships with others who can do the metal for them and then ship the final product to us. There must be so

Does anyone have experience with placing heat sinks on BGAs? I have limited experience with PSA (pressure sensitive adhesives)heat sinks, and am interested with the possibility of a clip-on device. I am specifically concerned with ease of assembly
