AI Technical Summary

Technical Problem

Existing optical communication devices have small thermally conductive cross-sectional areas in their packaging shells, numerous interfaces with high thermal resistance, low thermal conductivity, and complex structures that are prone to voids, affecting the stability and reliability of the chips.

Method used

By replacing traditional gold-plated ceramics with ceramic substrates, chips are directly mounted on the ceramic substrates. By increasing the thermal conductivity cross-sectional area and reducing the number of interfaces, combined with the brazing and sintering of Ag72Cu28 solder and metallization treatment, the thermal conductivity and mechanical properties are improved.

Benefits of technology

It improves the heat dissipation performance and mechanical reliability of the package, reduces interface thermal resistance, enhances chip stability and integration, and simplifies the structure.

Abstract

本申请涉及一种光通讯器件的封装管壳及其加工方法和光通讯器件,封装管壳包括框体、底板、出纤管、玻璃绝缘子、引脚和陶瓷基板,引脚通过玻璃绝缘子固定设置在框体上,出纤管也固定设置在框体上,陶瓷基板固定设置在底板上,陶瓷基板的上端边缘设有台阶槽,框体下端固定在台阶槽上,陶瓷基板上表面用于固定芯片。芯片直接贴装在陶瓷基板上表面,产生的热量先传递到陶瓷基板上,再传递到底板上,最后通过底板快速将热量散去,本申请能增加芯片的导热截面积,还减少了界面数量,从而减少界面热阻,提高导热效率,具有更好的散热性能;另外,陶瓷基板抗弯强度高,综合机械性能好,省去了热沉及镀金陶瓷,结构更为简单,提高了可靠性。
