I've seen this problem on more than one wave,What i've done is to run the conveyor a little faster,use a solder temp of 505 degrees F,and most important is to make sure that the solder is flowing over the back. this will keep the thin buildup of dros

It does sound like your leads are to long, speeding it up will reduce volume on lead and most will wick up the joint but when slow excess solder is left as long leads will have little flux left to aid drainage when it leaves the wave, thus giving a s

In reviewing the JEDEC 95 guidelines (2002) there is not a mention of tolerances that have been agreed upon for today's finer pitch devices. There was no mention of the solder diameter tolerances (low melt temp) allowed for 0.8mm, 0.6mm and 0.5mm pit

It seems that sceening at -20�C and using a vibration profile similar to the one you mentioned does a good job of high-lighting defective solder connections on assembled boards, but not affecting good connections. Why is this happening? In there a

I experience dull solder at the reflow station runing some SMD LED. It is a reject for dull solder. Is there anything wrong in the setting of the oven temperature? Temerature too high or too low? Pls advise. Thank You Rdgs.....

I like to know under what conditions the reflow profile of a solder paste is taken? Bare board, board with the solder paste, or board with high melt solder paste?

Hi, Friends, Could you please recommend me some solder mask materials and equitements for high quality solder mask? Details such as company name, phone numer et al are welcomed. Thanks! Have a good day Xingsheng

Agreed. In my experience you will not wet solder to: Platinum Iron Constantine Tungsten Carbide titanium Chromalloy allomega alloy 303, 304 ...and the list goes on and on. You will either need to weld or braze. These are high temperature prcesses

Hi, So about SPC by variable: flux drop-jet size, preheating, high of solder flow. attributes: soldering defects. I hope that the info will be helpful.

I am seeing high solder bridging for Nexlev Connector.Can someone advise what are the factors causing Solder Brdiging for Nexlev issues.
