摘要
针对前期研制并已商用的波纹管温控器有机溶剂过多,卤素含量过高等问题,研制了一种水基低卤助焊剂。助焊剂以选用丁二酸、己二酸、有机卤盐活化剂M作为活性剂,OP-10复配蔗糖酯作为表面活性剂,聚乙二醇作为成膜剂,并使用正交实验法确定各组分配比。研制的水基低卤助焊剂对温控器造成的腐蚀更小、产品可靠性更高。
In order to solve the problems of too much organic solvent and too high halogen content of bellows temperature controller, a low halogen flux based on water was developed. Using succinic acid,adipic acid, organic halide activator M as the flux, OP-10 complex sucrose ester as the surfactant,polyethylene glycol as the film agent, and using orthogonal experiment method to determine the distribution ratio of each group. The water-based low halogen flux has less corrosion to temperature controller and higher reliability.
