Hello experts, I wonder if you have any recommendation regarding reducing the boards needs to be washed out.... it is mainly generated due to first miss-printing after each Production Order setup.... but since board washing is a very manual process,

Hello Frank, Just a quick note regarding the use of your Smart Sonic Stencil Cleaning process for cleaning PCBs; if the boards are populated, some components my require an ultrasonic rinse with DI water as ultrasonics will deliver the wash solution

Also, get your PCB suppliers to send you BBT failures that they would usually throw in the bin. In addition to print testing you and use them for profiling. We use a sticky film for print testing, then wipe, peel off and throw in the bin.

It was a resonant frequency that brought down the Narrows bridge. Memorex can shatter a wine glass with resonance. Ultrasonic washers use frequency to do what they do. If anything on the pcb has a length width or mass that resonates at the washers fr

Hi Diego, Yes, we use a low tack Polyethylene tape, 300mm wide in reels of 250m. It's about 75 micrometers/ 0.075mm / 0.003", although we are looking at going down to about 0.06. Not all boards go through SPI, some just go through 2D - depends on

Mike Conrad's "matter of full disclosure" is not quite complete. He fails to mention that he only makes spray-in-air board cleaners and only ultrasonic stencil cleaners. He does not make ultrasonic board cleaners. So, he apparently he is "grinding

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.

Thank you guys. And Yes, the process and knowhow of the team has a lot to be worked on, but Work Orders are of 5k to 10k units, so miss-printings will occur everytime that the printer is setup at the very least. I wonder if you have a PCB washer to
