Just a basic suggestion.... Inspect the nozzle placing the component...because that is the only medium, apart from the PCB design, which can be causing the damage. It occurred in my Department.

Can anyone help to identify this little tan/brown colored pcb part? (The one labeled GND) I believe it's called an SMD ceramic capacitor but could certainly be incorrect. There don't appear to be any marking on it so beside the tan color, picture qu

Hi A lot of good answers. "No verification was done on the part as it was deemed to be a "straight replacement". Sound familiar?" Yes this sounds familiar, yet I am never sure it is a new supplier or component problem. It could be that the old par

I've never seen this before and I would be suspicious. Have you tried to dust it off with a brush or Q-tip, it might just be some sort of process contamination. Have you looked at the reel to see if the parts are coming in with these spots from the

Do you have to 'break' the pcbs from a panel or biscuit or are they individual pcbs form the start ? Poor pcb separation techniques or processes will damage ceramic caps.

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

Soldering PTFE boards * Exposure to the high temperatures needed for solder reflow poses no problem of loss of peel strength since the exposure times are relatively short. * There are many different types of PTFE based products that may perform diff

After a detailed check the cracking was most likely from the ICT and a variation in the length of the probes (due to wear and tear) that press down the PCB. I am very certain that was the reason.
