yes and thanks for this feedback. we clean with degreaser ( strong) and flux is rosin with 10% in the paste (koki). we clean after second reflow . the gap time from bottom to topside completion is 10 hours. cleans with this time. my even after 20 h

how long i can keep pcba after bottom reflow soldering to top side reflow soldering. like 12 hours or 24 hour or 48 hours........Enig board. leadfree soldering with 10% flux

There are multiple methods where you can perform top and bottom reflow soldering simultaneously. With this method, you might not worry about the type of flux there is. Each part is covered and baked as per the requirement, while making sure there are

It depends on the flux type. If it's water soluble, it should be cleaned soon after reflow because OA flux remains active after reflow. If it's rosin or no-clean (low-residue), then the only concern is the longer wait time, the more difficult it will

Any machine or process to clean up 400 used PCBA a day?

Help us understand your question better by answering the following: * What is a 'used PCBA'? [Are these boards returned from a customer?] * What is on these boards that needs to be cleaned? * How clean do the boards need to be? How is this cleanline

I'm not too experienced with this but what about an air-blast with an ionized air source such as an air knife above and below a conveyor to push most of the fluid off of the pcba then run through an oven just above vaporization temperature.

Dear Team, Can any body suggest that which is the best cleaning agent to remove the AIM M8 Flux residues from the PCBA After SMD Assembly by using Air agitation Method or with Ultrasonic Method.???

I have a plant in Shenzhen China and i am trying to locate a manufacturer of an inline cleaner for PCBA cleaning. Preferably manufactured in China. I am aware of the cleaner manufacturers in the USA. I use DI-water only no chemicals.

Questions are: * Are these lint-free rags ESD-protected? * How do these lint-free rags remove the flux that seeps under components? * Have you considered flux pens as an alternative to your current process?
