Solder Preforms – Another Choice for Solder Volume Increasing Solution

post on February 1, 2016

Today, most of electronic components are developed into smaller size. The small chips are downsized from 1206 to 0805, 0603, 0402, 0201, even to 01005. The size of chip is smaller; the required solder volume is less. Moreover, the required … Continue reading →
