Note that after the chip capacitor is installed, the chip capacitor belongs to the multilayer chip ceramic capacitor. We all know that the ceramic is very brittle and easy to break. The material of the chip capacitor is high density, hard, brittle and abrasive. The damage rate of the chip capacitor during transportation and use is high, causing damage to the chip capacitor: crack, high temperature, bending and other reasons, the following small series will introduce to you to avoid the chip capacitor What are the precautions for damage?
The ceramic body that requires attention to the chip capacitance during transportation and use is a brittle material. If the PCB is bent, it will be subjected to a certain mechanical stress. Pay attention to the following aspects during handling:
1. The printed circuit board is protected by a soft protective pad between the board and the board during transportation (sponge, pearl cotton, cardboard, etc.);
2. The circuit board should be handled gently during use to avoid collisions caused by rough operations;
3. The circuit board should be placed on the soft protective pad or placed in a plug-in type. Do not stack it at random;
4. Select the appropriate sub-board method to prevent uncontrolled deformation of the PCB.
When judging the damage of the chip capacitor, it is necessary to pay attention to mechanical damage or electrical damage. Check whether the chip capacitor has cracks or voltage breakdown, etc., and measure it with an electronic measuring instrument.
