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

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:

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

Hello Jon (?) Sounds like it's just plain too hot. The Panasonic VA series specifies a maximum preheat temp of 160C for

I worked for Electrovert for 20 years and up till today the 1421 is still the oil of choice. The chain doesn't care who's oven it's running in but it does require regular lubrication.

We use it and have had no issues on either oven. 1 Conceptronics, 1 Heller.

We have quite a few stencils that either are debonding, have debonded, or we suspect will debond when we can least afford for it to happen. The epoxy is coming loose from the foil, but remains attached to the webbing. All the stencils that are comi
