I Am SORRY; I mean of corse ING. I must be tired, because I start mix one author whith the next one. Just imagine what I will do with the alloys :-) Sincerly,

I am running a MYDATA MY19 machine.the problem is that the first 2 hours after turning on the machine it does not work throwing the following error: "transducers do not agree". After approximately 1 or 2 hours the machine starts working normally. T

According with temperature vs. wetting force diagram 245-250C/degrees is better, so lower temperature than 500F means better solder fill. If the speed is too lower the solder suck out form the hole. Usually 120-150cm/min. is good. (2-4s contact

Thanks Patrick, I our mixed standard HASL/RoHS production area; our customer have choosen Ni/Au plating for their RoHS boards. What You are saying (3.); is that we should be more attentive on the quality of the pcb manufactory. Even if our customer

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

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.
