摘要:

通过对10号优质碳素结构钢、玻璃熔封件的热应力计算,阐明了10号优质碳素结构钢、玻璃熔封结构的可行性。通过采取控制玻璃用量、合理设计孔口、烧结模具、优化工艺过程等手段,解决了熔封件玻璃开裂、漏气和管壳的抗蚀性等问题。机械和温度应力试验表明,采用该材料的金属电子封装外壳漏气速率不超过1×10^-3Pa.cm³/s,并能承受24h盐雾试验。

Abstract:

Based on calculating the thermal stress of number ten high-quality carbon steel and glass sealing parts, the feasibility of the sealing structure is described. By controlling the glass dose, rational designing the aperture and sintering dies and optimizing the manufacture process, such problems as glass crack, air leakage and corrosion resistance of the metal package are resolved. Mechanical stress and temperature stress tests show that the air leakage rate of the electronic package is less than 10^-3Pa.cm³/s, and the package can withstand the 24-hour salt-fog test.
