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

This is what I was thinking, but I am being beat up pretty badly by the selective solder. Ambient temperature is anywhere in the the neighborhood of 76 - 80 degrees F. I am not sure of the RH, but I wouldn't think that would be my issue... One of

Ball Grid Array (BGA). A surface mount technology leadless package with the connectors to the board placed in an array on the bottom of the package. They are attached to the board with tiny balls of solder placed on each contact. Pin Grid Array (P

I agree with Joris. But to add to his comment, the type of finish also has a direct affect to your wave solder process. Going from a gloss finish to a matte finish may help a lot. As for humidity affecting your wave - I doubt it. I use a water

Does anyone know of a freely-available document which discusses the main considerations of BGA assembly and inspection (x-ray?). l need to know about pad sizes and inspection standards and when to underfill and when not to etc.. l am looking at ass

Hello Mark, I wish it were that simple so I could direct you to a particular manufacturer and stencil cleaner model. Unfortunately, there are several issues complicating the process of cleaning all these applications in one machine. First and fore

Truthfully, there are pro's and con's for both technologies. (put cost of ownership aside for one moment) Nitrogen won't dry humidified components as rapidly as a desiccant dry box. I'm talking about a self regenerating dry box that uses molecular s

What is the current spec for sizing PCB pads for a land grid array? How about for a ball grid array? Are there industry spec's I can reference? Thanks, Frank
