High Requirements PCB for Extreme Fields
PCBs built for harsh, extreme environments must perform reliably under punishing conditions: extreme temperature swings, high humidity, constant vibration, severe shock, and
PCB: Plated Vias
Plated vias are one of those PCB processes we use all the time—but they’re easy to overlook until something goes wrong. Put
PCB Solder Mask: what it actually does (and why most boards are still green)
If you’ve handled PCBs long enough, you’ll notice one thing pretty quickly—most boards are green. Not because engineers care about the color,
Development prospect of IC carrier boards
IC carrier board — also called a packaging substrate — is essentially a high-end PCB that acts as the signal bridge between
Impedance Control： Characteristics and Methods
High-speed electronic designs rely on stable signal transmission, and trace impedance management sits at the core of reliable performance. On standard circuit
What is FPCB?
If you work with consumer electronics—cell phones, notebooks, digital cameras—you’ve probably handled FPCB without realizing it. Short for flexible printed circuit board
How should you identify the components on the PCB?
In our daily PCB assembly and maintenance work, we often see new technicians struggle with component identification. It’s a foundational skill—after all,
What is the chip test?
Every integrated circuit is built to deliver consistent electrical functions, and even minor physical defects during production can make a chip unusable.
FFC VS FPC Connector
When designing portable electronics or compact devices, we often get asked: what’s the difference between FFC and FPC connectors? Which one should
PCB Drilling Dimensions
Vias are among the most critical features in multilayer PCBs, and drilling costs typically make up 30% to 40% of total PCB
Advantages of Aluminum Core PCB in Heat Dissipation
For LED drivers and high-power integrated circuits, heat buildup is one of the biggest threats to performance and lifespan. This is exactly
How to prevent false and false soldering defects in PCB Assembly?
In PCBA (Printed Circuit Board Assembly) processing, soldering defects are one of the most common issues we face. Among them, false soldering
What is Copper Clad PCB? Design & Grounding Guide
What’s the Deal with Copper Clad PCB? (And Why You Should Care) If you’ve spent any time staring at a bare board layout,
Consumer Electronics: Flex PCB Prototypes Are Increasingly in Demand
In the age of miniaturized, lightweight consumer electronics, Flex PCB Prototypes (also called flexible printed boards) have become indispensable. They’re used across
The Basic Principle of PCB Layout
PCB Layout refers to the rational arrangement of electronic components and routing of connections on a circuit board. Done properly, it directly
Why the through-hole should be plugged ink?
Through-holes connect different layers on a PCB and carry electrical signals between them. As electronics keep evolving, PCB fabrication and SMT assembly
