Yeah, I'm assuming as long as the oven is profiled with a thermal profiler, and we're controlling the humidity, we should be fine. Thanks for your reponse!

Victor, I am wondering why you are keeping the RH as low as 32% ?? The lower you go, the higher your ESD problems will be. The voltages generated at about 40% are roughly halved when you reach 55% I believe that an acceptable level is about 55%-65

By looking at the solder balls they have not joined with the other particles that are alongside them. suggesting that they did'nt reflow. But they could very well be as you suggested, reflowed and ejacta from the process. We have been experiencing

Hi all, we will be moving our pcb production to a different (newer) part of the plant this summer in an effort to reduce dust and better control the temp/humidity. What can I install to keep the dust down? Are there air exchangers/filters for a room

I thank everyone for their input, I have ordered a few missing parts and will try the auto dispense feature. I believe our production floor humidity is properly controlled so hopefully no problems in that area. I do have concerns with the dispenser s

Emmanuel: Popcorn effect is mostly caused by entrapped moisture in the components package material. Plastic ICs are known for absorbing and storing moisture when exposed to normal factory conditions. They should be stored in an moisture reduced envir

Most of the component vendors I've dealt with will guarantee the solderability of the terminations for three years if the components are still packaged in a full reel. If the reel is part used we've kept them for 1 year and then used a wetting balanc
