The outermost circuit of the PCB is connected to the adjacent inner layer with a plated hole. Because the opposite side cannot be seen, it is called blind hole.
For the whole board positioning of the PCB circuit board and the reference symbols for the positioning of the fine-pitch devices, in principle, the QFP with a spacing of less than 0.65mm should be set at its diagonal position; the positioning reference symbols for the imposition PCB daughter board should be paired Use, place on the opposite corner of the positioned feature.
Selecting the appropriate copper weight is a crucial decision in PCB design. The copper weight, typically measured in ounces per square foot, directly impacts the performance, current-carrying capacity, and thermal characteristics of the PCB. In this article, we delve into the comparison between 1 oz and 2 oz copper PCBs.
Printed circuit boards (PCBs) are the fundamental building blocks of virtually all modern electronics. Understanding their composition is crucial for engineers, designers, and anyone involved in bringing an electronic product to life.
High-Density Interconnector (HDI) PCBs are essential in modern electronics, offering advanced technology that makes electronic devices smaller, faster, and more efficient.
In printed circuit board (PCB) design, inner layer clearance refers to the spacing or distance between adjacent copper layers within the board. This clearance plays a crucial role in ensuring proper signal integrity, electrical performance, and reliability of the circuit.
As a design for high-speed serial transmission, to suppress reflection, reduce transmission loss, and suppress noise,
A component called a coil (inductor) uses the magnetic field generated when this current flows. A coil (inductor) has two major roles, one of which is to store energy. The other role is to prevent AC current from flowing (which depends greatly on the frequency).
The trace width, the measurement of a conducting copper pathway on a PCB, holds immense significance in ensuring efficient current flow, minimizing voltage drop, managing heat dissipation, and preserving signal integrity. In this article, we'll discuss what is pcb trace and why is it important to consider when designing PCBs.
In the printed circuit boards (PCBs), fire retardant 4 (FR4) material is one of the most widely used materials in the assembly and fabrication of PCB.
Cleaning a printed circuit board (PCB) is a crucial but often underappreciated step in ensuring the performance and longevity of electronic systems. Whether in manufacturing, repair, or field maintenance, residues like flux, dust, and moisture can compromise electrical reliability, coating adhesion, and signal integrity. This guide focuses on when cleaning is necessary, what kinds of contaminants are involved, and how to carry out cleaning effectively—without damaging the board or its components.
