Ceramic Capacitors FAQ

Mounting

Do you take any precautions related to application of flux to chip multilayer ceramic capacitors?

  1. An excessive amount of flux generates a large quantity of flux gas, which can cause a deterioration of solderability, so apply flux thinly and evenly throughout. (A foaming system is generally used for flow soldering.)

  2. Flux containing too high a percentage of halide may cause corrosion of the outer electrodes unless there is sufficient cleaning. Use flux with a halide content of 0.2% max.

  3. Strong acidic flux can corrode the capacitor and degrade its performance.
    Please check the quality of capacitor after mounting.
