Embodiment Construction
[0016] In order to make the present invention easier to understand, the present invention will be described in more detail below in conjunction with specific embodiments.
[0017] First of all, design the chip directional suction cup, blank positioning cover, solder paste box and solder paste pen tooling. The specific design is as follows:
[0018] .Chip directional sucker design: design the hole depth of the current sucker from 0.5mm to 0.35mm, and increase the chamfer of 0.1mm around, so as to facilitate the 100% reverse (flip) function of the chip;
[0019] Blank positioning cover design: designed as a thin aluminum alloy frame, the purpose is to position the blank on the blank tray, so that the blank will not be lifted up during the solder paste dipping operation, resulting in uneven solder paste;
[0020] Solder paste box design: It is designed as a small aluminum alloy groove, and the solder paste dip pen is just placed in the groove; the purpose is to make each point of...
