Thanks you for the information LUPO, specially with component minimum clearance. I will also check the XY table for movement accuracy. What specific parameters do you check with your SPC charts. Thanks Crishan

Crishan, You must be seeing an incredible amount of Attrition on this component if this is the case. You should most definitely be able to put in a Pick-up offset either at the machine or in the part data. aj

For these type of connectors proper underside board heating, a customized nozzle and careful past printing are the keys to reworking properly. Pls contact BEST Inc at http://www.solder.net offline if you need someone to look at these for you. Regar

Fuji will not sell the reel by itself. also, you need to change the tape guide to 0.7 in order to place the 0402. Tape guide cost you almost a hundred bucks. I don't think it is a good idea to modify the feeder.

Joseph, What is the topside temp reading of your board before reaching the pot? Do you have top-heater in your wave machine? It sounds like; you got an insufficient per-heating issue.

Are we talking: * BGA that you've reballed and want to clean prior to attachment to a circuit board? * BGA that you've attached to a circuit board after correcting something or other? ... and we're talking a water soluble flux or what?

Stefan, I am surprised that you have made a un-wise purchase. You need to keep your eye out for unreliable suppliers. Sounds like he just wanted your money, not a good business relationship. Tommy
