We are reflowing ceramic resonators and are finding their tops falling/popping off when handling the pcbs during final assy. The epoxy seems to be coming off the components base and adherring to the lid. The components are "RFM resonators", case type

Hello Craig Are code dates other than these two coming apart or do they stay together? If other dates stay together you should get together with RFM. Did the process work before and and the defects just start happening? These are pictured on the RFM

It was a resonant frequency that brought down the Narrows bridge. Memorex can shatter a wine glass with resonance. Ultrasonic washers use frequency to do what they do. If anything on the pcb has a length width or mass that resonates at the washers fr

Thanks for the info Patric...! Using that I found the resonator on the Manu's website. Armed with that and info I recvd on the PIC, I jumpered across the resonator and the board now functions. We'll be testing tonight with the Heli and see how it

WE ARE USING A SMT CERAMIC RESONATOR ON A COUPLE OF OUR BOARDS AND THEY ARE CAUSING FAILURES, DUE TO UNCLEANLINESS UNDER THE PART. WE NEED A WAY TO STAND THIS PART UP OFF OF THE BOARDS, OR IF ANYONE CAN SUGGEST ANOTHER WAY AROUND THIS? THANK YOU, TO

I have a problem with a Murata cap chip type resonator(ROHS). After the reflow process, the soldering joints flow to one side of the component. I did not have this problem with the leaded component. Did someone have a solution for this problem?

Can't say too much about the solder joints issue, but about a decade ago we did have a lot of problems with resonators being damaged by harmonics from Ultrasonic board washing & Ultrasonic welding. However this mostly manifested itself as cracking i

Hello John.L I�ll think it is an Ceramic Resonator,The manufacturer might be Murata.

Do all of your PCBs come from the same supplier & are they HASL?
