Product Description Yoshida Welding uses the newly developed precision ball making technology to produce high precision spherical solder, and at the same time, it adds a small amount of additives to improve the heat resistance, fatigue and jointing performance. It is suitable for semiconductor BGA, MCM, CSP, Flip Chip and other advanced IC packages and microelectronic harnesses, optoelectronic devices and micro welding applications. From the smelting and manufacturing of metal alloy with special technology to customized research and development to meet the diversified needs of customers, precision ball making technology can produce high-quality solder balls with a diameter of 0.05mm-0.76mm.Product features:Stable solder ball size and composition ensure high yield during remanufacturing.High precision screening and grading technology improves size uniformity.The precision ball making technology makes the tin ball have high roundness and surface uniformity.Impact resistant and highly reliable solder ball1. ApplicableIt is suitable for semiconductor BGA, CSP chip package repair, microelectronic wiring harness, optoelectronic devices and other connections.2.
