I have difficulty to convince my management to air-condition our manufacturing facilities. The room temperature fluxuates from 8 deg.C in the morning to 25 deg. C in the afternoon. The PCB topside temperatures in the reflow oven and wave soldering ma

We now put soldermask on copper and then immersion nickel/gold plate our fine line boards. One of our vendors says this causes skipped plating in small via holes and wants to nickel/gold plate the whole board, including via holes, and then apply sold

we have just started wave soldering passive SMT components and through hole. We are having trouble with voids on the SMT components. It is very random, but effects a lot of TSOT's. We are using an electrovert with a chip wave. Are there any obvio

We use Immersion Gold (AuNi) for our 20 mil pitch and BGA boards. Lately, we have been having solderability problems with boards with this surface from some of our suppliers. We are considering trying boards with White Tin solderable surfaces such D

Has anyone had trouble waving and gluing 0603 R's and C's? At my company, our designers have "opened the floodgates" on bottom-side 0603's. We've got an EPK+ with rotary chip and omega wave but can't seem to get skip-free soldering on these guys.
