#137898 - BGA soldering Responding to: ???'s previous message |
I've soldered some BGA-25ish packages using a hot-air gun. Held the PCB with pliers over the air stream, moving it around to help heat everything more evenly. If I didn't have the hot air gun, an electric griddle should work well also.
Worked the best if I put a very small amount of solder paste on each of the pads before putting the part on. That helped transfer heat from the PCB to the balls on the component and melt them. As for placement, it just needs to be close. Once the solder melts, surface tension will pull the part around to the right place. Actually really cool to see when everything melts and the part moves to where it should be. But... this mainly depends on the size of the part. -Dave |
