We produce an ultrasonic soldering system, the G35. The system has unique
capabilities to solder without flux, attach dissimilar metals, attach metals
to glass, ceramic, etc. Please see our website www.fibrasonics.com for more
information, or contact us and our application engineers will be happy to
assist you.

>A couple of years ago I used an Ultra-Sonic solder for static solder dip.
>The solder pot was by Black Stone Ultra-Sonics. It had a foot peddle you
>pushed, which activated the Ultra-Sonics. It was very effective. I was
>having a major problem with the leads on some PGA substrates. They were
>KOVAR leads and the nickel plating over the KOVAR lead had spots where the
>plating was very thin (less than 100u inches, or non-existent). The iron
in
>the KOVAR lead was leaching through the nickel plating leaving black spots
>which were unsolderable. Since the substrates were expensive and the
>supplier would not accept responsibility for their defective parts we had
no
>choice, but to try and rework them. I stripped all the Lead/Tin plate off
>the leads. Soaked the leads in Nickel-Nu. Replated the leads with Nickel,
>and Ultra Sonically solder dipped the leads. In some cases I was able to
>perform the tinning process with no flux. The rework process was very
>successful (75% of the substrates were salvaged), and I believe the high
>success rate was partly due to the ultra sonic solder pot.

>If you're having an issue with unsolderable surfaces, and the product can
