We've had to hand solder 1 or 2 pins in cases like this or you could use chip bond or some adhesive on the component body.

If you do not have one of the big in-line aqueous cleaners, then there is an easier way that is a lot less expensive. I suggest you try Asahi's AK-225T vapor degreasing solvent which has been around for 10 years now. And it is legal. If you have

Flashback time� Vapor degreasers, although still used in limited applications, no longer represent the conventional wisdom (due to multiple environmental issues). Aqueous-based technologies are the most common method of defluxing. Unlike most va

Vapor phase or vapor degreasing cleaning for electronics is simple technology that holds merit on process situations like you described. Easy and quick to set up and process with today's modern equipment you can be up and running in no time once the

Principle A layer of photosensitive material (photosensitive oil or dry film) is applied to the copper foil on the board surface, and PCB manufacturer should be use the position is exposed by black film, This applies to most PCB factories, especially

Manufacturers involved in critical product cleaning may be aware that the U.S. EPA may ban or highly restrict the sales and use of n-propyl bromide in manufacturing. The EPA is interested in the impact on small businesses including costs and performa

In section 7.3.2 of ANSI J-STD 001 " Drying / Degreasing states the assembly may be treated to remove moisture and other volitiles" I have contacted one board manufacturer who states that it is recommended to bake a board to remove volitles. Are

I have heard of this but do not have direct experience. Immersion tin is susceptible to moisture absorption particularly after washing off solder paste. So it sounds like your boards are picking up the solvent off the screen. Water rinse or degrease

You can try using the brand-solvent "Genesolv 2004" in conjunction with a degreaser machine(source for own machine type?). this all helps to clean off the NC flux. we used it all integrated together, to clean a satellite modular card. reason we ha

Dear Adam, Yes, today certain companies are still using this cleaning technic to clean assembled PCB's. To be able to give you the right advise, I need to know what kind of fluxes are you using into your soldering processes and what level of cleanlin
