I'm trying to find information/articles describing the effects of temp and humidity on solder paste. Just recently we have gone through a change outside temperature and humdidty and have notice solderabilty problems with smt boards.

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

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

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

What type of product are you talking about in SMT? The SMT05E series are non-isolated DC/DC converters packaged in a surface mount footprintgiving designers a cost effective solution for conversion from a 3.3V to 5V source. Operating Temperature is -

Hi all, Is anyone used to encounter PTH(plated through hole) crystal component(Not SMT component) become malfunction when the environment humidity is more than 90%? It is happening here...It is very weird that crystal become OK when humidity is bac

Sorry that I'm so late responding. Your new additon probably has 'backee stains on the floor already. Assuming we're talking about a fairly standard board assembly area, you don't need to specify air quality. 1 We specify * Particulate: Level to b

Hi Tim, 8-mil huh? Boy, that's getting down there...you know, placing 8-mil is one thing, but printing solder paste on 8-mil pitch is another. Most of the time when I've seen 8-mil pitch on a board it's been attached with hot-bar...but I guess

Can anybody help & confirm the Humidity & Temperature Range to be maintained on SMT SHopfloor according to the IPC standard & its IPC standard number. Also the ways to compensate the humidity if its out of range; low cost / natural method.
