We did check for oven clearance thinking the same , but there is plenty clearance. We have however found that the problem was on several lots of PCBs. We ran a fresh lot and problem went away. There appears to be some kind of contamination on the PCb

Dear Pro, Pls, increase temperature up to 255ºC and considering solder's profile. Good luck

Dear pro, Could you show the solder's profile.

Thanks Anshang38 I'll try and get a profiler.

Thanks Evtimov, The flux is brand new and the amount of flux is enough and consistent across the surface of the boards.

Dear Pro, Pls, try to get solder's profile from solder supplier. That is the most important in wave soldering process... if not you will be difficult for improvement. Good luck.

Hi all, Could someone suggest a web site that contains good representations and pictures of SMT solder related defects?? I need to compare these with some pictures I'm using for a project presentation this week. Thanks, D.

Hello, Sorry for the mistake. The speed is 1m/min. We are using Alpha Vaculoy solder and a conveyor angle about 7º. We are not using pallets since the fingers hold the boards directly. Thanks!

Luciano, It looks you have no flux there. Please flux one board by hand and send it through the wave. That will eliminate a lot of the possibilities.

Dear Pro, I want to confirm with you about conveyor speed. is 1m/s? We are using wave soldering but it is 1.2m/min, min not second. Pls, check it agian. The flux is not relative this error. It is relative no sodering, bridge. The solder bar is the
