High-temp ball Sn10Pb90 + eutectic solder paste is common place for MLC reflow. Temperatures necessary to alloy the high-temp ball Sn10Pb90 and eutectic solder would be high enough to compromise interposer, board and many components. What are your:

Here's what I use: Sn10/Pb90, 268C-302C

I am considering using high-temp ball Sn10Pb90 + eutectic solder paste for MLC reflow (no underfill). You can see that there is no Intermetallic bond for the paste and the balls. Under high stress/shock condition, the solder joints develop micro c

I was looking through a solderability spec and ran across the term Nordau (Terminal finish - 90Sn/10Pb, Nordau, Matte Sn). I've never heard of this finish before, what is it?

Tuan: Consider Sn 96.5/Ag 3.5 or Sn10/PB88/Ag02 also. As Glenn says, you had better get rid of that gold or you will never have a shiney connection. Not that a shiney connection means anything about the quality or reliability of your soldering. M

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

Kester makes a thermocouple solder: Alloy SN10PB88AG2 Flux "44" Core 58 Diam 0.031" I have used this to solder thermocouples to pcbs when profiling for lead-free temperatures. When done you can unsolder the thermocouple and reuse it again. This g

I have contacted both vendors with this issue and the both said they have never heard of such a problem and that they could offer no type of explanitation.The leads are 90 sn/10pb and 98sn/2pb respectivley. The parts are all connected to the vcc and

O.K., I give up. I am through trying to solder thermocouples on to 20 mil pitch QFPs. Whether it's my lousy technique (fairly likely), the wrong solder (Kester calls it thermocouple solder, and who am I to argue...it's a Sn10Pb88Ag2 alloy) or just
