对19批国家质量抽检彩电用高频小功率塑封器件的可焊性,采用润湿称量法,进行了客观评价,给出数据和结果分析,指出:在国内19个厂家中大约有三分之一的厂家产品可焊性符合国标GB2424-21-85标准规定要求,其中三分之二厂家产品的可焊性在及格线以下,对可能产生润湿不良的原因作了分析,并与槽焊法结果作了对比。 Nineteen batches of national quality sampling color TV high-frequency low-power plastic encapsulation device solderability, using wetting weighing method, an objective evaluation, given the data and results analysis, pointed out: In the domestic 19 manufacturers about three points One of the manufacturers of products meet the national standard GB2424-21-85 weldability requirements, of which two-thirds of the manufacturers of products in the pass below the pass line, the possible causes of poor wetting were analyzed, and with the groove Welding results were compared.
