| | 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 t

Cheers Dave, to answer some of your questions. � The component lead is copper with a tin / lead coating. The pads are standard Copper / Nickel / Gold. � The solder is standard Tin / Lead / Silver (2%) We have a lab that can determine the composition

use a solder join temperature of 200/210� whatever the pcb used (tin lead coated or osp or gold fash). 2nd ==> to adapt the temerature to the pcb used: - Reflow (200-210�) for tin lead coated pcb's (in this case we have just to reflow the solder

Teh amount of silver on an immersion silver board won't effect 62/36/2 tin/lead/silver solder, however if the silver on the board is on the thick side and you have a high trace silver content in a 63/37 tin/lead then with the combination of the two y

SAC BGA In A Sn/Pb Reflow Process Conclusion: Area array components (ball grid arrays, chip scale packages, flip chip packages) with Pbfree solder sphere alloys should not be reflowed using a tin/lead reflow profile due to the resulting non-uniform s
