Document Type and Number:
WIPO Patent Application WO/2022/218332
Kind Code:
A1
Abstract:
Disclosed in the present invention are a glass-packaged ceramic feed-through filter and a preparation method therefor. The glass-packaged ceramic feed-through filter comprises a guide pin and a metal housing sleeved in the middle of the guide needle. The bottom of the metal housing is packaged by a glass body. A gasket sleeved on the guide pin is provided above the glass body. A disc-shaped multilayer ceramic capacitor is sleeved on the guide pin above the gasket. A first gap is formed between the bottom of the disc-shaped multilayer ceramic capacitor and the top of the glass body. A second gap is formed between the disk-shaped multilayer ceramic capacitor and the inner wall of the metal housing. The first gap is communicated with the second gap. According to the present invention, the size of the first gap is increased by means of the gasket, an organic solvent can conveniently enter the first gap for soaking and washing in the later period, the second gap is reserved between the disc-shaped multilayer ceramic capacitor and the inner side surface of the metal housing, such that the first gap is communicated with the second gap, and therefore it is convenient to effectively clean the residual position of a soldering flux, and the residual problem of the soldering flux is effectively avoided.
