SN100C is the Nihon solder. I had wave solder the board using SAC. Then had to put on solder pot, which had SN100C (nihon) solder. I think I went upto 130-135 deg C.. Let me try cooking it to 150degC Thanks

I have modules that come with a 4 x 2 pin header. The problem is the pins must be oxidized as they do not take solder (no wetting occurring). This occurs whether solder in our wave soldering machine or soldered by hand. I tried cleaning the module i

I just got back from a visit to our PCBA manufacturer. We have good flowthrough on the PTH, but solder skips and bridges on the SMT SO IC's. We have correct orientation and robber pads, but the results are still the same. I noticed the wave shape is

Hi Scott, Here is another thought. Check your wave solder machine visually. Does the wave flow on both sides of the nozzle? If not, you may have some dross build-up which may be causing your problem. Generally it will only happen on the very fir

It is possible to use a selective wave soldering fixture to "mask" the BGA devices from the wave. Unless you have a very thick board or one that is tough to heat, you should have no problem with BGA. Of course you should run some process experime

Larry, SOTs are a wonderful thing to try and wave solder! They are about as nice as Tant caps. I have found that shadowing is usually the biggest problem assuming that the other wave parameters are good, in your case it seems that they are. Couple

Amen to that Patrick. I am from a traditional Engineering background myself - they never taught wave solder in school. My curriculum was mostly theory and labs. When I got out, I read all the soldering books available at the time and also watched s

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

Hi, i try to collect data for solder wave process defects, but I dont know how I must calculate these data.Can anyone help me - may be there nave some free software for this.I want to calculate how many ppm is our deffects.And, how is acceptable ran
