为解决紫外成像器件光电阴极与管体封接漏气问题，对管体InSn合金熔化过程中出现的质量问题进行了深入分析，找出焊料熔层缺陷主要来源于对焊料除气不彻底和基底表面氧化及设备油污染。通过优化工艺参数，改进工艺质量和把化铟设备管体搁置焊料熔化改为浇铸熔化，使管体焊料熔化合格率达到了100％，光电阴极与管体封接气密性成品率达到98％。

To solve the problem of ultraviolet imaging device sealing leakage between the photo‐cathode and the tube body ,we deeply analyzed the quality problem of the tube body InSn alloy in melting process ,and found out the solder melting layer defect came mainly from the incom‐pletely solder degassing ,the basal surface oxidation and the equipment contaminated with oil . Through optimizing the process parameters ,we improved the process quality and changed the indium equipment of the tube body aside solder melting into casting molten ,to make the quali‐fied rate of the tube body solder melting reache 100% and the qualified rate of gas tightness be‐tween photocathode and tube body sealing yield to 98% .
