I should specify that I am using SAC 305 as well.

It could be lack of preheat or flux. You can verify the flux by hand applying. I'll bet it's lack of preheat though. That's usually the case with selective solder.

I am doing lead free testing on a Vitronics selective machine with a 4 mm nozzle. The finishes I am testing are ENIG, ImSn, and ImAg. The problem I am encountering is achieving good top side wetting. Has anyone had any luck with this type of an ap

Check flux penetration and type of flux. How much is solid contents. The solder filling is better under Nitrogen. Check the time (speed) of the nozzle whether is correct. Usually For SAC305 the temperature of bath is 320C/degrees, but only for sel

Have anyone perform wave soldering on FR-2 and FR-1 printed circuit board with lead free soldering? Can you share the parameters(wave temperature,preheat temperature, contact time, wave height,etc,) used and did you do any changes to the wave solderi

Is anyone wave soldering 0603 leadfree succesfully? We have no problems soldering them leaded, but lead free we see a lot of random skips and some shorts. We use SAC. We have tried different fluxes, flux settings, playing around with preheat, sol
