Sounds to me like they are thinking since they have a gold board that it must be processed lead free. This kind of thing is happening all over since OEMs are starting to think about pb free and sending their purchasing and engineering to these semin

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

We have a simular problem with Ni/Au; especially whith pcb thickness more than 1.8mm. Note: These boards have been through reflow process also. 1.)Is there a maximum board thickness where it would be almost impossible to get a decent hole fil? 2.)Wi

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

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

Mika, 1.) Is there a maximum board thickness where it would be almost impossible to get a decent hole fil? Answer: The thicker the board the further the solder has to travel and the more you depend on solderability of boards and components, machine
