The invention provides a solder pre-planting device, a pre-planting process and a packaging method. According to the device, through
collaborative design of the T-shaped cavity structure, the height adjusting mechanism and the ejector pin stopping piece, accurate positioning and hovering control of the bonding pad are achieved. Wherein the micron-sized annular gap realizes the functions of heat insulation and overflow prevention, the mounting tolerance and the alignment precision are considered after the size of the micron-sized annular gap is optimized, a manual adjusting mode and an automatic adjusting mode are provided, and the operation flexibility and the
automation prospect are considered. Through the design, the
welding flux forming stability and the product yield are remarkably improved. The pre-planting process based on the device can form a standardized solder body at an independent
station, and the packaging method adopts two times of
reflow soldering to realize reliable connection. According to the whole scheme, through cooperation of the device, the technology and the method, the production process is simplified, dependence on the precise printing technology is reduced, and efficiency improvement and
cost optimization are achieved while the
automation level is improved.
