Distribution Plate & Shim
Distribution Plate & Shim
The tin ball distribution plate—also referred to as a ball feeding plate—is a critical component in laser ball pickup and soldering technology, designed to enable the automatic dispensing and feeding of solder balls.
During the laser ball pickup soldering process, the distribution plate rotates, allowing individual solder balls to drop from the ball reservoir into the nozzle. The nozzle orifice is slightly smaller than the solder ball diameter, causing the ball to temporarily seal the nozzle opening. Nitrogen pressure then builds up inside the nozzle. A laser beam irradiates the solder ball, melting it instantly. Under the force of the pressurized nitrogen, the molten solder ball is ejected onto the target pad. The combined thermal energy from the molten ball and the laser facilitates fusion between the solder ball and the pad, completing the solder joint. Throughout this process, a continuous flow of nitrogen prevents oxidation of both the solder ball and the pad.
Moreover, the design of the tin ball distribution plate is optimized to enhance feeding efficiency. For instance, certain patented technologies incorporate a rotating placement plate directly beneath the solder ball storage cartridge, eliminating the time required for balls to slide from the cartridge to the nozzle—thereby significantly increasing dispensing speed and overall operational efficiency. Additionally, a vertical ball delivery tube installed directly below the storage cartridge and aligned perpendicularly with the distribution plate ensures precise ball alignment during feeding, minimizing misfeeds and further improving reliability.
In summary, the tin ball distribution plate is an indispensable element in laser ball pickup soldering systems. Its design and optimization play a vital role in enhancing both soldering efficiency and joint quality.
