I looking for a beta site for a new drying process | 18 August, 1999

We have developed a new process for removing moisture from surface mount devices. We have one site where PCB laminate drying has been reduced to 1.5 hours. A standard oven took 4 hours to do the job. I am looking for a firm who does large scale board drying to beta site the TVP process application. Anybody getting tired of waiting for the stuff to dry?

He's been looking to DRY his very large solder mask output, but not over do it in, in a much shorter period.

What is the principle? If we knew how it worked, we could judge better.

We originally developed the process to dry thin, moisture sensitive surface-mounted IC packages. Sugsequently, ABPAC proved that it was equally effective in drying BT laminates used in PBGA assemblies. A West Coast military contractor is using TVP to dry some military PCB's but is super secretive about the product, keeping us in the dark. He does report that he was able to reduce his 4 hour cycle to 1.5 hours with the TVP process. The lack of answers to questions like solder masks is the reason that we are looking for a "technical partner." There is one "bright light". The process has been able to beat standard bake-out cycle times by 50% or better in all applications.

Sure didn't mean to be the least bit secretaive about TVP. I didn't think the forum would be happy with a posting of all the details in this format. You will have to forgive me, I'm a bit of a "newbie" to bulletin boards. I would be more than happy to post the process details for thermal vacuum processing anywhere at any time. Just need a little guidance on how to get the inormation out.
