Ceramic foil chip capacitor mfr. - where stacks of metallised foils sepd. by ceramic slip are cut into small stacks, baked, and then sepd. into chips

摘要

Metallised, crude ceramic foils are assembled together to make blocks (a). A vertical stack is then made from several blocks, which are each sepd. from the adjacent blocks by a ceramic slip. The stack is then cut into numerous small stacks (b) by a milling machine; and the small stacks (b) are baked to sinter the ceramic before stacks (b) are sepd. into separate, small blocks (c). The ceramic slip is pref. applied by spraying, and consists of a mixt. of a solvent, a binder, and an inert filler. The binder is pref. an hydroxy-ethyl-cellulose, esp. a methyl-hydroxyethyl-cellulose. The pref. milling machine uses three disk milling cutters so three cuts can be made simultaneously in a block. Rapid mass prodn. is achieved.
