Ceramic block side wall printing method

Abstract

The invention relates to a ceramic block side wall printing method in a photoelectric module. The method comprises the following steps of a, superposing four layers of ceramic substrates and printing a metal slurry on a top surface of an upper layer or a bottom surface of a lower layer; b, laminating the four layers of printed ceramic substrates of the above step; c, carrying out hot cutting on a laminated sheet material of the above step to form a rectangle and printing the metal slurry on one group of opposite side surfaces of the rectangle; d, carrying out hot cutting on the sheet material on a direction vertical to the direction of the side surfaces printed with the metal slurry of the above step to form an upper ceramic block (1) and a lower ceramic block (2); and e, laminating the upper ceramic block (1) and the lower ceramic block (2) to form a ceramic block. Compared to the prior art, by using the method in the invention, a mode of carrying out printing after lamination and hot cutting in the prior art is changed, which means that single ceramic block printing is changed into multiple front integral body printing, wherein the multiple front integral bodies are formed through the hot cutting; work efficiency is increased; printing quality is good; other surfaces which do not need to be printed are not influenced and simultaneously production cost is reduced.

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.
