Flash gold is just thin electrolytic gold plating over electroless nickel or electrolytic nickel. Flash gold plating ... * Less than 3 microinch thick will be porous and take solder poorly * Greater than 10 microinch thick will cause brittle solder c

Below is the long explanation. This defect is most commonly found with BGA components, but can arrise with all components. I see it happening more now with lead free boards that are being assembled with a no clean flux. Best short term remedy is t

My name is Geertjan de Beijer and I am new on this forum. I have a question about Electroless Nickel/Gold finishes. Until now we always use a HAL finish on our PCB's. Since we are using compontents with pitches of 0.5mm we notice that the HAL finis

I have a new customer who is recommending a Sulfamate Nickel Finish for his boards. I'm not really familiar with this process. Is anybody else? How does it differ from electroless nickel? Can a standard NC solder paste cut the mustard with this stuff
