MLC reflow using high temp Sn10Pb90 solder balls

Electronics Forum | Mon Nov 12 15:21:09 EST 2012 | davef

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:

MLC reflow using high temp Sn10Pb90 solder balls

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

Kester has a special alloy for high temp soldering. Alloy 123. I would think that if you coocked 63/37 to 360c you would have a pot of dross in no time! Doug

Hi, I'm an SMT refugee working in component manufacture - hey, times are hard! I've been asked by a customer to test some of my parts at high temperature on the wave - up to 360 deg Celsius. I've checked my wave and it's only capable of getting up

Can you use 96s solder wire on a pcb that has been plated with standard 60/40? if so what are the effects on the proerties of the 96s? If you cannot mix the two solders is there a more effective way than braid of removing the 60/40 from the plating?

Russells: You can mix the two solders you mentioned, assuming by "96s" you meant "96Sn / 4Pb". If you heat the two tin / lead alloys to a liquid state, you�ll form a tin / lead solution with properties different from either of the two solders. The

I am having problems with SMT electrolytic capacitors expanding and changing values after going through our reflow. The reflow profile we use includes temperatures of 200 deg C for 60 seconds and 230 deg C for 30 seconds. We need to use this profil

we are using alphametals no clean 95sn/5ag CL775 paste. After reflow there are solder balls on the board. mainly are around the cap. We are using a conceptronic concept 60 air. There are 4 zones with 8 chambers. We are not sure what the profile
