玻璃粉对片式电阻面电极耐焊性的影响
Influence of different frits on solder-resistance of chip resistor surface electrode
摘要
Abstract
The effects of two kinds of frits, Ca-Si-Al-B and Bi-Si-Al-B on resistivity of chip resistor surface electrode (C1) were studied before and after dealing with soldering. The results show that C1 products have good electrical property and excellent solder-resistance property when mass fraction of Ca-Si-Al-B glass powder is 4%-6%. The analyses of the SEM and EDS declare that the silver layer of the C1 is well-stacked and continuous, which contains Ca-Si-Al-B glass powder after solder-resistance. This is mainly due to the silver being cordoned off by the calcium feldspar needle structure during the Ca-Si-Al-B glass powder sintering and the larger surface tension of the solder.关键词
