网络变压器防高温开裂工艺浅析

Analysis of High Temperature Cracking Prevention Technology of Network Transformer

网络变压器进行回流焊时往往伴随着产品开裂现象产生,本文结合材料膨胀特性以及吸潮特性等方面对开裂现象进行了理论分析。通过进行工艺方面的研究与验证,得出产品回流焊合格率可以通过调整灌封胶配比以及试验前增加烘烤等方面进行改善和提高。

The network transformer reflow soldering is often accompanied by product cracking phenomenon.In this paper,the cracking phenomenon is analyzed theoretically from the aspects of material expansion characteristics and moisture absorption characteristics.Through the process research and verification,it is concluded that the qualified rate of reflow soldering can be improved by adjusting the ratio of potting glue and increasing baking before the test.
