You should tell your customer that they're very nice people, but the purpose of RF shields is reduce RF emissions, not to be a air or gas tight enclosure. The requirements of hermeticity are wholly different than those of RF shielding. Do they want

Please give some suggestions on removing RFI / RF shields ... PTH Shields: Removing PTH RFI / RF shields is as straight forward as the next PTH component. Small SMT Shields: Removing small SMT RFI / RF shields is fairly straight forward, providin

Bob: Techniques for removing RFI / RF shields vary according to the size and type of shield. Removing: * PTH RFI / RF shields is as straight forward as the next heat sinking PTH component, often using a solder bath or fountain. * Small SMT RFI /

Hi Anyone has experience in manufacturing RF PCB and encounter voids on the grounding pads? The grounding pad is covered by the a big component. Question is does voids in the solder joint affect the RF operation?

Residues from different no-clean fluxes produce different levels of variation in RF circuits. Some no-clean fluxes work fine. Following this, a no-clean flux can produce different levels of variation in RF circuits depending on the process setup.

I am trying to convert a customer from a water wash process to no-clean but am receiving much resistance. They suspect that no-clean residue played a part in field failures they experienced several years ago. They are quoting an AT&T study that state

DAVE- The way we got around it was simple- Our Mole for profiling is RF and the cell phones would interupt the data transfer so we nixed all cell use. Also, our BTU oven was in constant RF communication with our KIC and so cells were band from the fl

Problems using NC in RF circuits are peculiar. Depending on the situation [ie, circuit layout, frequency of use, processes used, materials, and what not], a particular NC flux may not work with a RF circuit. Various NC fluxes leave different levels

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
