Vietnam Lead Tin Balls

- Appearance: Silver-colored, spherical solid with a bright finish.

- Composition and Impurities: Elemental analysis using inductively coupled plasma atomic emission spectroscopy, with tin, silver, and copper controlled within ±0.5%, ±0.2%, and ±0.2% respectively. Harmful lead content controlled within 500ppm cadmium, mercury, and hexavalent chromium under 2ppm.

- Oxygen Content: Controlled at approximately 0.01% using precise oxygen analyzers.

- Diameter and Tolerance: Tolerance controlled within 0.008mm - 0.020mm.

- Shelf Life: 18 months when stored in a sealed container at 10-20°C in a dry, cool place.

- Quantity per Container: Depending on the ball size, ranging from 125,000 to 1,000,000 balls.

- Applications: Ideal for micro soldering applications such as BGA (Ball Grid Array) semiconductor packaging, MCM (Multi-Chip Module), CSP (Chip Scale Package), Flip Chip, advanced IC packages, as well as optoelectronic devices and microelectronics extractors.

Key Features:

- Stable Size and Composition: Ensures high yield during reflow processes.

- Precise Screening and Sorting Technology: Enhances size uniformity and ensures high sphericity and even surface.

- Excellent Soldering Performance: Impact-resistant, reliable, with bright solder joints and minimal residual flux.

- Outstanding Soldering Capability: Short wetting time, even rosin distribution, minimal spatter and smoke.
