BGA Baking & Tape and Reel Issue| 14 September, 2004
At the moment I bake all BGA that are in unsealed trays, to reduce moisture etc. Is this common practice or are there particular manufacturuers that cause more problems.
Also, the tape for BGA tape & reel has a hole in the tape (as is normal practice). Should I see less problems with T&R BGA than Trays. Because the tape is not completly sealed, are the BGAs still taking in moisture or are they not as the hole is somewhat sealed from the overlap, from being reeled, on the reel.

Left to its own devices the plastic used to seal your parts will take-on moisture in the air. When you heat there parts the water in the part expands and can damage the part, if not properly demoisturized.
