Some of our panels are gold plated. We use our normal production paste and/or wave soldering process. Shiny joints do not imply good reliability relative to dull joints. Look at the microstructure. I have not had any failures attributed to this come back from the field. The only difficulty I had was with top side fill on the solder machine. ______________________________ Reply Separator _________________________________ Subject: ASSY: Gold-to-Gold Soldering Author: [log in to unmask] at internet Date: 9/30/96 6:21 PM Does anyone have experience soldering gold-plated SMT components to gold-plated PCB's using a eutectic (Sn63/Pb37) solder? The solder joints exhibit a dull, grainy appearance. Although I know that longer liquidus dwell times and a maximum reflow temperature of 220 C are typically recommended when soldering to gold, will other solder alloys perform better (i.e,, Indium alloys)?
