300 million boards to date). I also have some reliability data for joints made with these 2 alloys wave soldered and then repaired with both. All of these results look good. The issue we see is mixing SN63 with any of the lead free alloys. Sn63 wave

USING LEAD FREE PARTS WITH LEAD PASTE

Electronics Forum | Sat Dec 10 20:58:05 EST 2005 | Mike

How about this scenario: Need to rework a BGA on a 2 year old board. Originally the board was assembled with Sn63/Pb37 and the BGA has eutectic spheres. Now this package only comes with lead free balls. I believe that the board finish is not idea

Sn100C HASL Finish on PCB

Electronics Forum | Wed Jan 26 17:36:22 EST 2011 | ck_the_flip

had a quick question regarding compatibility of Sn100C HASL finish and regular Sn63 solder paste. Does the thermal profile have to reach Sn100C eutectic temps. in order for the Sn 100C HASL to coaelesce with the Sn63 Solder paste? How reliable is t

Just some more info: PCB is HAL finished we are using Sn63 solder paste.

No problem in that.

Lead free SAC solder paste on Sn63 HASL PCBs

Electronics Forum | Tue Jan 06 16:31:41 EST 2015 | jacklucas

In switching to lead free processing, we find ourselves having over 400 PCB part numbers with Sn63 HASL finish. And there is no hope of quickly purging inventory and getting our drawings changed to call out a lead free finish. I want to avoid having

Lead Free solder Rework

I need information on where I can purchase Lead free solder paste and solder wire samples. I currently use SN63/PB37 no clean solder paste in a 35G tube and SN63/PB37 no clean solder wire for rework. I would like to try out some samples of Lead fr

Lead free SAC solder paste on Sn63 HASL PCBs

Electronics Forum | Wed Jan 07 14:33:00 EST 2015 | eezday

The assumption that a HASL Sn63 PCB can be soldered with SAC solder paste is likely a bad one. The board itself is likely FR4 which can be damaged by lead free temperatures. The HASL finish isn't an issue from the perspective of it's makeup and actu

We agree with Pat, but it's far from straight forward. [er maybe we should say we don't understand it.] We duplicated the results of a posting on the web. Flux, then dunk copper wire into tinning pots set at 250*C for measured periods of time. The
