Subject: ASSY:BGA Moisture Handling 1997.12.0310:37 AM Hi TechNetters, I have some questions about handling of moisture sensitive BGA's (and other components). 1. Where can I get a low RH (<5% RH) oven for baking BGA's at low temperature (40'C) ? (Tape and Reel does not appreciate the 125'C bake for 24 hours!) What method are you using for baking (eqmt, temp., time) ? 2. Are there other methods used to control "repeated" exposures of components other than a "follower" which travels with the Reel / Trays ? 3. Where can I get a proper sealer for MBBs (moisture barrier bags) ? Is there a method to verify that the seal is sufficient ? 4. Is there a commercial training package available for handling of moisture sensitive components ? Your help is greatly appreciated. Charles Elliott NPI Process Engineering Newbridge Networks Corp.
