【摘要】 针对航天电子产品高可靠性的特点,对紫外光固化三防漆进行研究,通过一定光照强度紫外固化专用炉实现快速固化、工艺参数量化可控,达到提效提质、节能减排的目的。结果表明:使用DSL1600E-FLZ/75紫外光固化三防漆,对含各种集成芯片及不同焊接封装形式器件的印制板组装件涂覆,配合紫外炉固化后,涂层与印制板结合力达到2级及以上,防湿热、防霉变、防盐雾等三防性能符合GJB 150.9A-11A要求,满足航天电子产品三防防护要求。更多还原

【Abstract】 Discusses research of UV coatings on spaceflight electron products,using UV cure lamp to achieve coatings cured speediness,advances the quality and reduces vent.It is indicated that spreading the DSL1600 E-FLZ/75 UV cure coatings on PCB with the UV cure lamp,the combinability of coatings can reach the second class and upwards.The performance of anti-humidity,anti-mildew and anti-salt measure up GJB 150.9 A~11 A.It is satisfied the requirement of spaceflight electron products.更多还原
