Specific steps for PCB surface treatment
ByGrace July 15, 2025July 15, 2025
I.PCB surface treatment: After drilling, there will be residual copper foil burrs attached to the surface of the through hole on the PCB surface. At this time, the surface of the board will feel rough when touched by hand. These burrs will affect the quality of electroplating, so they must be removed. The steps for…

PCB Characteristics and PDN Performance
ByGrace July 15, 2025July 15, 2025
Basic design rules for power distribution networks (PDNs) tell us that the best performance comes from a consistent, frequency-independent (or flat) impedance profile. This is one reason why power supply stability is important, because a poorly stable source will result in impedance peaks that degrade the flat impedance profile and the performance of the powered…

PCB Rigid Boards vs. FPC Flexible Circuits: A Comprehensive Comparison
ByGrace July 14, 2025July 14, 2025
Introduction Printed Circuit Boards (PCBs) are essential components in modern electronics, providing mechanical support and electrical connections for electronic components. Two major types of PCBs are Rigid PCBs (Hard Boards) and Flexible Printed Circuits (FPCs or Soft Boards). While both serve similar fundamental purposes, they differ significantly in material composition, design flexibility, manufacturing processes, and…

How to set jumpers in PCB design
ByGrace July 14, 2025July 14, 2025
In PCB design, sometimes we will encounter some single-sided boards, that is, the usual single-sided boards (LED-type light boards are more often designed). In this type of board, only single-sided wiring can be used, so jumpers have to be used. Of course, in complex boards, problems that can be solved with jumpers are basically not…

PCB Routing Rules for Single-Ended Signals
ByGrace July 14, 2025July 14, 2025
Sometimes, the distinction between what is considered a “slow” or “fast” signal can seem arbitrary and can depend on who you ask. A related topic is whether a PCB trace is electrically “short” or “long,” and you’ll likely find just as much disagreement on that topic. Whether you need to route slow or fast signals…

Uncovering the secrets of PCB manufacturing process
ByGrace July 14, 2025July 14, 2025
Before the emergence of PCB, circuits were made up of point-to-point wiring. This method has low reliability because as the circuit ages, the rupture of the line will cause the circuit node to be broken or short-circuited. Winding technology is a major advancement in circuit technology. This method improves the durability and replaceability of the…
