Welding column flattening polishing auxiliary device on CCGA ceramic column grid array device and application method thereof

Abstract

The present invention relates to a welding post smoothing and grinding auxiliary device on a CCGA device and a using method thereof, wherein the CCGA device is fixed on the welding post smoothing and grinding auxiliary device, and its welding post protrudes from the welding post smoothing and grinding auxiliary device device, the welding post smoothing and grinding auxiliary device includes a box body, an adjusting gasket and a welding post positioning block, and the adjusting gasket and the welding post positioning block are fastened under the box body by several threaded fasteners , the welding post positioning block is provided with a microporous matrix formed by several through holes. The present invention solves the technical problem in the prior art that using metallographic sandpaper for manual grinding or directly grinding on a grinder can easily cause damage to the welding post.

Description

technical field [0001] The invention relates to a CCGA device, in particular to an auxiliary device for flattening and grinding a welding post on a CCGA device and a method for using the same. Background technique [0002] After the CCGA (ceramic column grid array) device is packaged, the free end surface of the welding post is usually an arc or spherical surface, not a plane. At the same time, the surface of the ceramic substrate of the CCGA device body is uneven, which also leads to the overall problem of the free end of the welding post. Jagged, poor flatness. If the welding post on the ceramic substrate is directly welded to the printed board, due to the poor overall contact quality between the welding post and the printed board, the welding quality is poor, and even some welding posts cannot be effectively welded, which directly affects the function of CCGA. Since the CCGA welding post is easily skewed under the action of external force, in the prior art, metallographi...
