Hello all, Can anyone know what influence has on RF/HF components when using PCB with OSP coating? We are now manufacturing our RF components on PCB with ENIG coating ,and want to use OSP instead. By the way:If anyone can send me an article on this s

I have a single sided PCB that contains 4 RF connectors that will require conformal coating. Sounds easy, well the RF connector is .080 in diameter and stands a whole .050 in height. The sub-straight that the barrel sits on is about .020 thick. I don

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

I'm new to all this... we have a board with one BGA blue tooth device. one test for the board is an rf test that measure successful packet transmission. we find that we get much lower error rates if we "reflow" the BGA with a heatgun. We do this

| Does anyone have any data or experience with voids in Glob Top applications? We are working with a RF application and I'm trying to find information on RF performance characteristics and moisture absorption on a glob toped devices. We have determin

I cannot give references to papers, etc, but I can tell you from experience that High Impedance circuits and High Power RF circuits are not something to try no-clean on. For an aerospace customer, I had a circuit that any residue left between two pa

We are in the early stages of converting al of our customers to No-Clean solder. I expect some customers to have no objections, others I am sure will be concerned about the "residue." I know that chemistries have improved greatly and if the process i

Howdy all! Nothin' up my sleeve!!! While attempting to reflow an RF antennae on std FR4, HASL coated, using no clean paste, in a Research Thermaflo 10, the part sometimes slides on one of the pads (as much as 0.125"). There is a slight amount of w
