I don't know about you but we use a ton of Kapton tape in our process. Does anyone have a good supplier for this?

Grainy finish of the solder joint also caused by higher reflow temp.So far we have observed grainy structure in case of gold plated board.

I have been using silver coated boards for over 3 years and with a Qualitek No-clean solder paste and have used primarily the same convection reflow profiles as Hasl boards.

I have heard that the profiles are pretty much the same but I have a visible solder joint difference... might half to start looking at the plating, might be something with that?

Hi Burb, I think you should try with paste which consist Ag.Or it might be other:Ag has different thermal characteristics, so you probably stay too long in the reflow zone.That's one reason for granular joints. good luck!

Yep, Across the board! It seems as though the resources available at our suppliers anyway have been diminished from the economy. But our orders and lead times are now getting shorter and shorter with more complex PCBs being demanded. another day,

Walt; How can I say this politely...Garth used to work for me. His enthusiastic support of the APS machines was not based on reality. We have had so many problems with our 2 machines that we are getting rid of them. I hope you make out better. G
