Side wall printing method of porcelain block

Abstract

The invention relates to a side wall printing method of a ceramic block in a photoelectric module, comprising the following steps: a. stacking four layers of ceramic substrates, and printing metal paste on the top surface of the upper layer or the bottom surface of the lower layer; b. The four-layer ceramic substrate printed in the previous step is laminated; c, the board laminated in the previous step is eagerly cut into a rectangle, and the metal paste is printed on one of the opposite sides of the rectangle; d, in the process perpendicular to the previous step Printing the metal paste on the side direction to hot cut the plate to form the upper ceramic block (1) and the lower ceramic block (2); e, laminating the upper ceramic block (1) and the lower ceramic block (2) to form the ceramic block. Compared with the existing technology, since the method of printing after lamination and hot cutting in the prior art is changed, that is, the printing of the original single ceramic block is changed to printing with multiple pieces before hot cutting, which improves the work efficiency and the printing quality is good. It will not affect other surfaces that do not need to be printed, while reducing production costs.

Description

technical field [0001] The invention relates to a side wall printing method of a ceramic block in a photoelectric module. Background technique [0002] The photoelectric module uses an alumina ceramic block as a carrier, and a circuit is printed on the surface with a special metal paste to conduct the inside and outside of the module shell. The external signal enters the inside of the shell through the circuit printed on the ceramic block, and the signal is processed by the internal structure before being transmitted out of the shell. After the alumina ceramic is laminated and cut into ceramic blocks, it needs to be fixed in the square groove machined on the side wall of the shell, such as figure 1 As shown: the top surface of the upper ceramic block 1, the bottom surface of the lower ceramic block 2, and the side surfaces 3 at both ends of the ceramic blocks all need to be printed with metal paste for welding and fixing with the shell. At present, the method of printing m...

AI Technical Summary

Problems solved by technology

Due to the small size of the ceramic block, the length is usually about 20mm, and the ceramic is very soft and easy to deform before sintering

At the same time, due to the small area of ​​the four printing surfaces, the printing efficiency of the side wall is low, and it is easy to be painted on other surfaces. It is easy to cause a short circuit during use, affecting the quality, low work efficiency, and high production costs.
