Beyond just the cosmetic dewets reliability is very flux/coating dependent. Don't forget about any touchup or hand soldered parts after wave as well.

As a band-aid, consider running your chip wave when soldering these boards [Similar to Cals "dance with me babe" suggestion.] If the problem is as broad based as you say and the radial components have a tight fit, consider increasing the holes by a

New pcba supplier sent us first article pcbas (SMT, Wave & hand solder operations) that failed our testing due to no-clean flux residues found under ICs and around passive capacitors. Second lot came in and had 100% pass yield, but we still see a cl

Are you using no-clean solder, or just no clean flux? If you're using a solder with WS flux in the core, and a no-clean flux; we'd suggest switching to a WS flux to help during the soldering. If you are using a no-clean solder/flux combination, you

| I am looking for information regarding post wave soldering of stranded wires into a circuit board using OA core wire solder. We do a final pass thru the cleaner after the hand soldering but I'm concerned about any OA flux residue that may have wic

| Does anyone have info on the rotary chip wave(compare/contrast to z wave.....)? John, In my humble opinion, rotary chip waves are the best thing since forced convection. Great coverage; never clog. And here's a really cool perk: the rotary chip w

We have been monitoring our solder defects at post-SMT, post-Wave, etc.in our plant. I want to compare our process performance to a "bench mark" for solder defects at post-SMT. The question I have is what is the "bench mark" for soldering defects in

| I am building a board with T1/34 LED's in a 10X10 array there are 12 arrays in a panel. The LED's are body to body in the array, .1 spaced. The LEDS have been autoinserted on a Universal RAD III, so they are cut and clinched. The trouble I am havin

You are not correct in assuming bot side temp as related to top side. This is entirely dependant upont the board. e.g. a PCB that is .4mm thick will almost be exactly the same temp top and bottom whereas this 2.4mm will be significantly less at the
