Dear all There are alot sockets in our products,BIB.These skts are lifted abit after being solderd with wave machine.If the skts become lifted, how much tolerance of the high is acceptable? as example 1mil~5mil,or,1mil~8mil. Pls advise me. Thanks in

| For some as yet unkown reason, we have started to have some boards sag and go under the wave. The boards are surface mount top side and conventional components wave soldered. We have checked the wave hight and both the profiles on the wave solder a

140..155 degrees celsus the limit is your inserted component temp schock tolerance

Lead free is not define as NO lead and "a maximum concentration value of 0.1% by weight in homogeneous materials for lead shall be tolerated." Check below link. So replaced your solder from the pot when exceed 0.1%. http://www.leadfree.org/files

Guys, what about hole to lead size? is it lead size + 0.010' + tolerance

Check the wave of each category ( ex. input , output ) . => Check these wave is in each tolerance or not . If you can forward to others who know, that would be helpful. Sunil Grover 408-245-9264x135 (O) 408-245-9284 (F)

The opening in the wave pallet for the TH connection in question would be a titanium insert rather than just a cutout in the durastone like normal. They're able to hold tighter tolerances with the titanium vs durastone as far as I understand.

Thanks for all of your suggestions. Since there are quite a few options, the selected method will depend on volume, tolerated cycle time, ROI, etc. I believe we will be dealing with relatively low volume, so I am going to investigate the selective w

Why don't you use peelable/washable solder mask on the SMT components next to the T/H pins? Then, you won't have to worry about keeping the tight tolerances.

Ideally? Never. You risk component break down by re-running the board over the wave machine. In a perfect world, your wave operator would make adjustments after one run, and you'd run another panel over the wave to judge the effectiveness of the a
