Miniaturization

Electronics miniaturization demands high-density solder joints as small as 100 to 106 μm in diameter.  Therefore, the size and geometry of solder joints are paramount issues in the implementation of lead-free solders.  To that end, the Intermetallic Compound (IMC) layer formed by Alpha’s solder materials is of optimal thickness for good wetting and bonding with minimized brittleness that increases mechanical failures.
