First off, are you planning on placing these parts with your placement machine since you mentioned that you do not have an alignment system for rework? I would be leery of handplacing a BGA into paste by steady hand and craned neck alignment. Seco

Fuji: Wonderful machine, very robust, Hardware second to none. Lacking on software Universal: Love the GSM, great platform. Sanyo HSP�s are ok, like the new 4796, not sure about the 4797 yet, have not had it long enough to give good data. Sieme

Hi, An interesting tread, Neat reading. Just pulled out a guide that was given at Nepcon West2000 entitled: Nepcon West 2000 Pick & Place Evaluation You might want to call them to get a copy of the report. As two or three others already pointed

1) Do people always bake, sometimes or never? Does this depend on whether MS sensitive components are near the rework site? If a BGA is to be removed and reballed, baking is a no-brainer. Sometimes, based on the proximity of the MS components. >2)
