We are currently experiencing thermal shock failure on a BGA package. We are currently looking at improvements to improve the thermal shock properties by using underfilm. I have seen some studies out there that use this process to improve drop test

I am working on a picosatellite and I have heard that surface mount technology works well. However, I don't have any details on this. Does anyone have any suggestions or project ideas that would work for shock mounting components inside of the sate

Has anyone had any experience with thermal shocking and cracking of SMD capacitors during the rework process? My company was advised to preheat capacitors to 125 C at a rate of 2 C/sec before replacing them onto boards. Would this maybe degrade c

Hi Could somesomeone help to let me know can bare PCB (FR4) is damaged by thermal shock? Can difference of CTE from copper or solder to FR4 damage PCB from apply heat too fast? Any specification or standard can i refer? Thank you Ben

I didn't know what you're talking about. If I wanted to better understand / learn how to reduce the effects of shock and vibration on electronic assemblies, I'd contact: Dave S Steinberg Steinberg & Associates Work: 818-889-3636 E-Mail: steinbergas

In addition to our earlier comments, do not be misled into thinking that silicone materials, being rubbery, will transmit shock less. Nothing is farther from the truth. Many silicone rubbers are almost totally incompressible in the short time scale.

Hi, Could it be shocks in transit? This is only happening on 1 product, so might point to chassis and packing design. Does anyone know of any shock indicators that we could put inside the chassis to see if the faults are caused by this? I have seen

I have a large monoblock ceramic filter on a PTFE based pcb material. The filter has a metal casing soldered onto the ceramic filter. I am concerned that if the heating rate is to rapid, then thermal shock / differential expansion could cause the fil

I have a project that I am working on and would like some input from anyone that has some knowledge on High Voltage Arcing on PCBs. Problem: I have a PCB that is enclosed in a plastic enclosure that has metal pins and switch that extend to the outs
