First, the product introduction
In order to adapt to the development of modern microelectronics industry, as an important auxiliary material for BGA and CSP in IC production, solder balls are widely used in modern microelectronics. They are notebook computers, mobile communication devices, computer motherboards, light-emitting diodes, liquid crystal displays, PDAs, The technical auxiliary materials necessary for the production of functional ICs, such as digital camera, play a vital role in the miniaturization process of large-scale integrated circuits. At present, the market demand for solder balls is very large, with an annual growth rate of nearly 90%. In particular, high-precision, small-diameter solder balls are seriously out of stock.
Our company has direct reading spectrometer, scanning electron microscope, inductively coupled plasma mass spectrometer, surface analysis technology XPS and so on. Excellent R&D team and experienced field technicians guarantee high quality products. The high production efficiency and output make the price of the product have a strong competitive advantage in the same industry. The powerful analytical instruments and control equipment ensure zero defect of the product.
Second, product features
1. The size range of solder balls ranges from 80 microns to 600 microns in diameter;
2. The deviation of the particle size of the solder ball is almost zero, and the ball and the ball show a high degree of consistency;
3. Precisely control the oxygen content of the solder ball;
4, long storage time, usually two years of validity
5, according to customer needs, add trace elements (Ni, Ge, Sb, etc.)
Third, the main push products
Our company produces lead-free solder balls: SAC, SnAg, SnBi, and SnSb. In addition, trace elements such as Ni, Ge, Sb, etc. can be added according to product requirements; leaded solder balls are: SnPb, SnPbAg, and high-lead alloys.
