PCB Design
Most board failures I’ve traced over the years didn’t come from faulty components. They came from subtle layout decisions made in the […]
PCBA solution
A PCBA solution isn’t just a stack of Gerber files and a BOM. It’s the design, the sourcing, the assembly, and the debugging that

Printed Circuit Board(PCB)
PCB(Printed Circuit Board) is the basic motherboard of almost all electronic products, serving as the core carrier for connecting and integrating electronic
The test methods of printed circuit board
A fully assembled board can look flawless under a microscope and still fail in the field because of a hidden open trace.
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
Alumina ceramic PCB
At some point, every power electronics designer hits the thermal wall of organic laminates. You can add copper pours and thermal vias,
Where FPC is used?
The first time I opened a flip phone, I was struck by how many gold-colored ribbons were folded inside. Today, FPC applications reach almost
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
IC Carrier PCB: The Bridge Between Silicon and System
The moment a chip package moves beyond a few dozen pins, the old metal lead frame stops being practical. That’s where the
How to solder a wire to a circuit board?
There’s a quiet frustration in watching solder ball up on a pad and refuse to wet—a problem I ran into far too
