Thanks for the advice regarding the ultrasonic spray fluxer ... we are currently using Delta Wave 6622c wave solder machine with dual spray heads (the ability to use two completely different kinds of flux chemistries). It's a great system that works

In almost every application an ultrasonic spray fluxer will out perform foam fluxing. Better soldering results are what most expereince after making the change to U/S spray. There are good ultrasonic units from USI and Sono-Tek. www.ultraspray.com w

Recently I completed a process evaluation on various stencil / misprinted PCB cleaning systems. They were both ultrasonic (theoretically can damage PCB�s) and the more conventional method of high pressure rotary bar method. I found that the best sys

| Does anyone have any recommendations on spray fluxers? Are there major differences between the high priced ultrasonic machines to the low priced flux/air spraying machines? We are going to be spraying an OA flux with 11% solids content. Are there a

We used to use spray machines. We now have a PMR ultrasonic cleaner. Ultrasonic is the best in my opinion.

Mike failed to list the company that introduced the first ultrasonic stencil cleaner in 1990. The company remains the leader in stencil cleaning worldwide: Smart Sonic Corporation Tel: 1(800)906-4407 Fax: 1(818) 909-6409 e-mail: smt@smatrsonic.com w

Spray cleaners are poor alternatives to todays ultrasonic stencil cleaners. Ultrasonics are the way to go and you can use rather benign water based chemistries to get the job done. As for screening adhesives and cleaning glue residue with spray wands

You are correct in your assessment that no-clean pastes are difficult to clean. I understand why you would need to clean lots of stencils, but why would you need to clean "high volumes" of PCB's? If you are planning on cleaning high volumes of PCB'
