Sizzling would be hard to hear our machine has forced air preheaters along with all the other ambient noise, so I'm going to say no sizzling. I've tried really slowing the conveyor down to see if it helped, I saw no noticeable difference.

A picture of the top side of the connector would be helpfull too. I assume the 2 large leads in the front are part of that connector too.

Lead spacing is probably an issue here. It would be better if your lead pattern was staggered, like the RJ-45 to the right. It appears there may not be enough flux on this part of the pcb.

I will give 90 deg turn a try, I want to say we've tried this in the past, but my memory is not what it once was, and the operators can't recall either. Thanks for the input, I'll keep you updated.

Try trimming the leads to no more than 0.020" instead of 0.040" (1mm). The extra labor on the front end may save on the back end especially if almost all your boards have bridges in this area.

Patrick and Dean, I'll try both suggestions in the next day or two and let you know what I find.

Yes, 45 degree will kill the shadowing effect. YOu can also consider the teardrop on its land. No need to tilt to 45 degree.

Dear All, can please tell specifications of heat resistant glass plate which is used to flux application and process control of wave soldering. can you tell the suppliers of the same in India. BR, Gupta.

Yes it is the massive ground plane stealing all heat. You need to have a thermal relieve design for that specific pad.

How full is the barrel actually getting? Per IPC-A-610, 100% fill is the target but 75% fill is acceptable for Class 1, 2, and 3.
