| Are square pads more difficult to wavesolder than round pads? | I am referring to a through hole board. | Usualy square pads are for indication of pin 1 on a DIP for example. There might be a difference in the capilary affect due to a different su

We have a new PTH board that utilizes lap pads on the B/S. Some of the pads are paired closely together and are aligned at angles (30,45,60 degrees)to the boards direction of travel through the wave. The pads most always bridge together. I realize th

| | I need to find out the benefits about having a spray fluxer.Right now we are using a foam fluxer on our electrovert wavesolder. We are thinking about investing in a spray fluxer and I want to know if anyone has used a spray fluxer and if any prob

Bob, The responses to my question kind of supported my first instinct to avoid waving TSOPs. Plan B may be to find a compliant pin connector and convection reflow both sides. Any comments? Greg : The first thing is all the TSOP suppliers like Inte

Adam, I would first check hole to lead sizes on the components that you are having hole fill issues with to see that the spacing is withing spec. Second, check for oxides on lead tips, and contaminated leads that cause poor wetting and insufficient

| Also the preheating of the board is done to help evaporate any water/alcohol that is in the flux - water is a big problem in No-clean processes. From our experience, a temp range around 200f - no more than 220f is ideal for the bigger boards, but t

Adam, Did some work on this a bit back via some good old Taguchi DOE and like Dave(the guru)F say's your component terminations is a big factor but I also foundthat the amount of flux you put on as well as the preheat's has an effect, generally we f
