Folks, has anyone heard fo any problems with RF cards related to solder paste selection. Currently runnign with std SnPb paste but want to move to 2% silver paste. Was asked if this could cause any issues in term's of RF capability or interferance t

We are doing assemblies using Immersion Silver coating for RF assembly for a while now. We did not have problem using 63/37 SN/PB solder paste untill recently. We started seeing black marks on the finish and around the solder joint recently. We have

We are considering retrofitting our Vectra wave soldering machine with a hot air knife. I've run our problem board on a machine with this option and it does seem to work; however, there is a concern of component failure due to thermal shock. Is thi

If a PCB is already going through ICT and some additional inspection method is desired to increase first pass test yield rates, what are the advantages/disadvantages of AOI vs XRay? The most common problems seen are missing or skewed components and

The 483 is what we use on all boards except on one where the 353 improved wetting on resistor packs. It worked much better since the parts are LF and this is the same flux AIM uses in their LF solder. Yes, it was recommended by AIM when we discussed
