| We process both tin/lead plated boards and gold plated boards in our surface mount group. I have used Sn62/Pb36/Ag2 solder paste on all gold plated boards to help prevent gold scavaging. To reduce the amount of different solder pastes we have to

When soldering your full tin (no lead) and Pb95/Sn5 solder components, you need to modify your PbSn reflow recipe to compensate for the higher melting point of the changed solder alloy [with your Sn62/Pb36/Ag2 solder paste] on those component leads.

Hi, I have read many articles about theromsonically bonding to soft gold. Many of these articles state you can bond to 10uinches of gold. I have worked with both Hughes and Panasonic bonders at two different companies and I have never been able to

For soldered areas, we like to keep gold thickness substantially below the maximum you propose. Search the fine SMTnet Archives for our discussions on the topic of acceptable levels of gold with solder connections. Let�s fix this �no one seems be s
