Steve Not too sure how much help this would be, but you might want to check with Exselect Engineering about solder pots. You might find what you need, new and at a very good price. Will send you an email with additional used equipment locations. W

Is there anybody with knowledge in the process with PHT components (Components with terminals) - Cause with make board with top and bottom side, with SMD and Auto Insertion Technology. So we want to do a Entire Cell with both technology, and without

Dear SMTneter, I am loonkig for some information about how to rework a BGA. Some technical info explaing how to put solder past manualy, soldering manualy, tips and so on. Where can I find something about? Thanks in advance Marcos

Another thing we see is solder balls (sometimes fines, sometimes larger stuff) in the vias after a misprint has been poorly cleaned, as in wiped down but not washed. They end up in the plated through holes too, but those get nicely cleaned up in the

Hi, Have you tried increasing the vibration at the main wave or using a chip wave? try increasing the temperature of the solder by about 10 Deg C.

Dear Frank, could it be that your component legs are coated with a leadfree finish? This can have an inpact on soldering when your temp.peak in only 220�C and the melting point of pure Tin is 237�C. Best regards, Daniel

It would be uncontrolled reflow process. Solder paste smeared, outdate solder paste, contamination, and many else could lead to this issue. A longer time reflow window would help elimating it (make it max. of 60 seconds liquid time).
