Thanks Patrick for the replay, No, we do not mix the alloys nor Pb pcb:s/RoHS pcb:s in the case I described. It is simply as this: With both the different soldering processes we facing this phenomenon; but whith the RoHS SN100 or SAC305 it turns out

Hi, What is the speed of the conveyir (contact time) and alloy: Pb free or not? Temperature of bath? Quantity of flux? Regards

For LUPO: speed: 4.5 inch alloy: 63Sn/37Pb Solder pot temperature: 500 Quantity of flux: just to wet the board

Thanks Patrick. I understand your points. It gives us good results. I didn't know about the flux activity on Gold finish. It's a pleasure to get this kind of explanantion.

Looks like an X-belt problem. is it tensioned correctly, not too loose or too tight? Or the X motor is acting up.

Not really, just eyeball. Does it look too loose or feel too tight. Is it lubricated properly, is there enough grease on the sprockets? Also, check the ribbon cables. They might be damaged.

I checked it and there is no problem with the lubrication the cables are in good condition. The band feels a little loose I will try to make the adjustment to see if that is the problem.

Mika, If I understand you correctly you compare hole fill of Ni/Au plated boards in a lead-free process with HASL 63/37 boards soldered with leaded solder. If this is the case you might be facing the challenges in Pb free wave soldering with the lim

I suspect the problem is a surfactant issue in your flux. I have seen where boards are fluxed, hit the solder fountain and come out like they never touched the solder. There was an inadequate surfactant between the solder and the PCB. I know you
