We have some humidity issues due to monsoon season in southern Arizona, I am having issues with water soluble solder paste, and moisture sensative IC's. We are trying to maintain a 32% relative humidity for EESD purposes. What is the standard, and w

I agree with Wolfgang. If you don't control your processes, they will control you ... and they will put you out-of-business, if you let them. Ta. Dave F

Hi! Mike My company is using the electric dry box and it can controlled less than 10% within 2.5 hours if we are not going to open the door. In normal working environment and it still can't control around 30%. Is it something that you are looking

Hi,how to control the solder paste,condition as belows? place at room temp.or put it into refrig.again if the unopened paste has been warmed up 8 hours but it would not been used at once in case of schedule changing.Assuming that this solder paste wi

Could anyone send me equations to calculate controlled impedance of traces on circuit boards. I am most interested in the buried traces in multi layer boards. Thanks, David - piengr@verinet.com

Dear Hussman We use automatic machines on mounting PHILIPS and though quality and velocity of their mounting are very good, the girls occupied with quality control can not on 100 % to check quality of the soldering FLIP CHIP and BGA!!! Pavel

what factors should be monitored and controlled during assembly of components on PCBs and their storage? Temperature and humidity seem obvious. Should one also watch out for any particular gases that may cause oxidation? Or dust?
