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.

OK, component wide portion runs with the conveyor, so really both sides should heat and cool at the same rate. The crack is at the termination between end cap and ceramic body and run vertically up the end cap, so when we remove the cap it comes of

Lets get to the simple things. Wave or Reflow? Wave soldered parts have a higher susceptibility to physical damage until they are waved. That�s were I normally see this type of break. Usually, the crack is a circular pattern in the cap if it�s fr

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.

Ceramic capacitors larger then EIA size 1812 are known to be very susceptible to thermal shock damage due to their large ceramic mass.

Hi, I am looking the practice when you are phasing in the LF wave soldering process of larger boards with Larger AL E- cap, are there any concerns about the heat resistant, is there any risk to damage the E cap as higher temp is a need for larger bd
