The assembly is HASL finished. The colour of the solder mask is green, ( sorry I dont know the technical name ).The flux is No Clean (Koki JS3000)which is seeing a preheat temp between 90-100degCel. The solder pot is set at 250degCel and is 63/37.

Any comment on the solder pot temperature setting, 500F (260C) or 482F (250C). Most of the manufacturer is using 500F in CA. Rgds. Dason

Speaker made of ABS material could not withstand temperature of 250 C after wave soldering, please advise what is the guidelines for such material to pass thru wave soldering process, is there any guide books for my reference.

Yes, that's what people are thinking. The 217�C melting temperature that you mention requires a ~250�C reflow temperature. Generally, boards, legend ink, and components cannot take that temperature. Further, few ovens can produce that temperature

Hi, I would like to have information about means to improve the stability of a SMD-Line: indeed the variation of the daily performance is too important (between 50 and 250 ppm). What is the solution to reduce these variations? climatisation, other re

Ken: At the end of arguing about how �myfloh� is calculating defect levels, reality sets in. �Between 50 and 250 ppm� is pretty darn good. Clearly, they have picked all the low hanging fruit.
