Sn62Pb36Ag2 has a higher liquidus point of 189C as compared to Sn63Pb37 at 183C. You may need to slightly adjust your oven profiles to use it compared to SnPb. We have had good solder-ability and reliability with it in our IPC Class II products. A

Sir The board is flight critical

One of the things you need to know are the parts you are building Flight Critical. Meaning if the board fails will it bring down the aircraft. Or non critical meaning one of the over head light will fail as an example this determines how much latitud

Sir I more information i did not shared with you. The finish of this critical board is ENIG. Do you recommend ENIG finish for the flight critical boards

Hi everyone! I am looking for a lead-free solder that will survive a customer reflow of 260C. I am currently using SN10/Pb88/Ag02 but the reflow temperature is to high (320C) for the FR4 boards that we have. I know there are higher temp FR4 boards

This is the perfect combination for the Mission Critical PCBs you require. All of our Airborne Customer Prefer a Leaded Solder to a Lead Free, and often require it. ENIG PCB construction is the strongest method of producing Mission Critical Systems.

Logannsan, you may want to check into this a little more with your customer to find out what 2 is. It could be as Vlad say's 2Ag -silver, or it could be 2CU -copper or 2Ni- nickel. Also check this form for 62Sn 36Pb 2Ag just my 2 cent. Regards

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 bu
