Kinda makes ya wonder why ya changed, eh? Some of our 20 pitch HASL boards come-out just as flat as a farm pond. Just got ta letum be. Pete is spot on!!

Pete, thanks for the input. These are microvias and dont go through the pcb -- they are laser cut to various depths into the board and are .006" dia. on gold plated pads. Paul.

Hello Russ, I'm not quite sure I understand your question. Are you saying that you must hand solder these connectors because the gold plating doesn't allow other though hole processing methods to wet the solder the length of the pin in the PTH? Reg

We have been encountering black pad contamination on gold plated boards mainly affecting BGA components during assembly. This problem has been noticed with many of our customers that are using an array of fab vendors. Does anyone have a solution fo

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.

YiEng, MA/NY DDave: Usually when the gold plating bath goes south, you loose solderability.

Hi Dave, Hmmm, pix F2? Do you meran figure 2 or second picture? The second picture is the bare board before printing. Gold plated pads. Is that what you mean? mk
