I bought an ultrasonic cleaner from the states and thought it would run with the usual travel adapter. So, I have obviously run 240v through a 110v unit. Something inside went pop and it hasnt worked since. Does anyone know which component on the cir

We have used good industrial dish washers in the past. We washed very dense SMT boards with mulitiple BGA's. they always passed Ionic tests. You can buy these for as little as $500. The less expensive ones won't hold up to 140F water and suponifier b

You may need a glue despinser if you populate bottom side then wave. maybe a board deatacker at front of the line how about a multifunction pick and place machine so you can process all parts out there. we cleaned our stencils for years then we got a

1. Use ultrasonic cleaner after you manually wipe out the main amount of solder. 2. Ask yourself why you have misprints so often. I work in this industry for 20 years and can't recall having many misprints. Something in your process should be fixed.

At the beginning, we absolutely do this with the first board. However, we do have some problem child jobs where we end up wiping 1 in 5 prints. When searching the topic, most of what I got was "ultra-sonic" cleaners, but that isn't recommended for

We purchased a Aqueuos machine that I would highly recommend to anyone. Before that, we used the ultrasonic cleaners with great success. We'd just run it for 5 minutes (whether the board is populated or not) and let it air dry under a blower and it w

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'

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

Hello Paul, Prior to 1980, I would say that your concerns were real regarding the resonant frequency. However, since then all major ultrasonic cleaner manufacturers use a "sweep" frequency technology. By "sweeping" or alternating the frequency bet

I've worked at several companies that have used Smart Sonic ultrasonic cleaners. About a year ago, we purchased the Smart Sonic 1550 and Enviroguard. The Enviroguard produces DI water for rinsing and also handles the solder waste. Also, Smart Sonic h
