Our SMT production and storage area is air-conditioned, constant temperature is maintained but the humidity is not controlled , the raw SMT material is stored in a "Drier" cabinet, but since we assemble hybrid SMT and thru-hole PCB assemblies, the SM

Handling requirements of all classifications of moisture sensitive devices is found in J-STD-033. It really isn't an issue for most parts unless they're going to reach reflow temperature again, which is unlikely unless you're removing a nearby compo

OA pastes are more hydroscopic than NC pastes. Hydroscopic. The capacity of a material to absorb and retain moisture from the ambient air. Sometimes this is compounded if you remove paste from the frig and let it warm to room temperature, because

Hi All, Would just like to course through this concern on a product that we are contracted to assemble. It is mainly used for an automatic hand sanitizer dispensing product. By design there is a restrictive value of current that it needs to dissipat

What about when using noclean and alcohol based fluxes? Could humidity still cause issues?

I want to get a collective opinion from the forum... I was always under the impression that Humidity at SMT can be a disaster and can cause solder balls... But what about at the Wave/Selective solder? If every board or almost every board has solder

We are enclosing our SMT room and will control the Humidity and Temperature of the room. Is there a standard for humidity and temperature for a SMT room and if so what is it. What is protocol if it goes out of tolerance? Do we stop production? Is
