PCB Assembly(PCBA)
PCBA refers to the process of transforming a bare PCB into a functional finished product through SMT mounting, DIP insertion, and rigorous
Does residue on PCBA have any effect on reliability?
When a board passes ICT and functional test at the factory but glitches six months later in a humid climate, my first
Parameter Characteristics of FR-4 PCB
Not all FR-4 is created equal. That’s a lesson you absorb quickly once you’ve ordered the cheapest sheet available and watched the
PCB soldermask process and some bad issues
Ask any PCB fabricator which process generates the most customer complaints, and the answer usually points straight to solder mask. It’s the
Flex PCBA soldering method
Getting a connector or wire to stay put on a flexible circuit is not the same game as soldering on rigid FR4.
Basic information of flexible printed ciruicts boards
Working with wearables and foldable electronics quickly teaches you one lesson: the rigid PCB has hard limits. That’s where flexible printed circuits come in.
The Thin Barrier That Keeps Your PCB Alive: Conformal Coating
In any PCB design that will see field exposure, conformal coating is often the thin layer standing between a long service life and an
