PROCESS OF ASSEMBLING SOLID ELECTROLYTIC CAPACITORS USING VIBRATION STEP WITH BOTH LOW AND HIGH FREQUENCY COMPONENTS

摘要

A solder preform slug and a processed anode are placed into a can. A glass end seal and an outer solder preform O-ring are placed on a lead extending from the anode. The assembled components are heated to the melting temperature of the solder preforms. The can is vibrated by applying high frequency vibrations to a bar supporting the can. The bar has a natural low frequency of vibration such that both the high frequency vibrations and the low frequency vibrations are applied to the can. The low frequency vibrations settle the anode into the can and release gases which are produced from rosin. The high frequency components produce rotation of the can which aids in the sealing of the end seal by the solder preform O-rings.
