.固化条件(Curing  condition)

○Recommended curing condition:Over 120 sec after PCB’s surface temperature has reached 150℃.or over 150 sec after PCB’s surface temperature has reached 120℃.

 

○When the higher curing temperature and the longer curing time,the stronger adhesive strength can obtained.We would suggest you to search out an optimum curing condition,for the temperature exerterd on the adhesive may occasionally vary according to the size,material,etc.of component parts mounted on PCBs.

 

固化条件

○建议固化条件是PCB板表面温度达到150℃后120秒以上,或者是达到120℃后150秒以上。

○固化温度越高,且固化时间越长,可获得更高的粘接强度,依PCB板上装着元件材质、大小不同而实际附加于接着剂的温度会有所不同,因此请依据实际生产情况找出最适合的固化条件。因此,在推力测试中,若推力不够,可以延长高温固化时间30秒,如将在150℃的时间由90秒升至120秒,十分有利于胶向元件和板材中渗透,就可以达到理想推力。
