It looks like solder dross there or flux residue that not activated well. Your speed is 43cm/60s, wave width contact is 2cm, so dwell time is 2x43/60=1.43s, it's short also.

We made much better contact of wave with board. There was not enough solder in bath. We increased it so wave height is higher with same pump power And now board is pushing dirty wave to the other side and board is much cleaner!

Look at this article http://circuitsassembly.com/blog/?p=191 The EU commission totally lost contact with the real world.

If you can, attach athermocouple to the locations where you are getting solder balls. A previous product I had showed the same thing and we found that we had inadequate preheat leaving the liquid flux to splatter when it hit the wave. It could aslo

We noticed unsufficient soldering on some 0805 chips located between pins from a plastic bloc connector . All chips are soldered with 45� angle. Flux quantity , preheating , contact time and PCB quality was checked. Do you know any international stan

Not as such. Choices are: 1 Cut and epoxy some board foil from your board fabricator. 2 Sacrifice part a pad repair kits from the likes of: * Engineering Lab 905-785-1982 * Circuit Technology Center 978-374-5000 * General assembly suppliers catalog

The best one is NOT one of the guns that the sales reps had to be deceiving to get their promotional pitch in without being up front on who he was or the other rep who tried to capitalize on the other A-holes deceiving tactics.... RIDICULOUS Contact

thanks again for reply, we have now configured speed of traveling so pcb can travel through preheat with one speed (call it v1) and through wave with other speed (call it v2). Lenght of preheat elements is fixed, so with speed v1 we can change pr
