All: I am reaching out to get some suggestions on the right flux to use as well as a recommended cleaning process for soldering a KOVAR RF shield using 80/20 Au/Sn solder to a ceramic hybrid. The recommended profile is 4-5 min at 280C and at least

The chain and fingers for our Wave solder is getting a large amount of residue from the flux (high dissolved solids) we are using. Any recommendations for products that can clean polymerized flux.

Hi Clarissa, seems to be a real start up situation you are in. For the printing there is IMO no need to buy any sophisticated automatic-vision-alignment-self-cleaning-inline-and-more-machine. Features you need: - adjustable in X-,Y-,Z-axis (individu

Well first off I wouldn't evaluate paste for a wave process. I would use solder bar instead. Flux - top side fillets and no shorting on the solder side, does it clean well after processing if using water soluble flux. How wide is the process win

We follow IPC-2221 recommendations for Au and don't have a problem as long as the Ni is under 150 microinches.This ensures a consistent process for us.Also we do plasma clean after SMt and prior to wirebond.That makes a big difference. Rob

And what is the solder paste selection recommendation for the same. 1. Water soluble ( organic based flux solder based ) 2. No clean ( rosin or resin based solder paste ) customer is suggesting water soluble chemistry , which is having lot hot an
