What Process Impact of Substituting SMDs with Paste-In-Hole components?
Someday, there is one question came from my manager, “Is there any difference or influence on the process and design if we changet the SMDs (Surface Mount Devices) to THDs (Through Hole Devices) type and go through the PIH(Paste-In-Hole) process?” … Continue reading

Solder Preforms – Another Choice for Solder Volume Increasing Solution
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
