Soldermask is a protective layer of liquid photo image able lacquer applied on the top and bottom side of a Printed Circuit Board. The function of the Soldermask is to protect the copper, apart from the solder pads, from:OxidationCreating shorts duringSoldering (bridges)Operation due to external conductive influencesOperation from net to net due to high Voltage … Continued
Circuit board warpage will cause inaccurate positioning of components; When the board is bent on SMT and THT, the pins of components are not perfect, which will bring many difficulties to assembly and installation. Ipc-6012, SMB–SMT circuit board of the maximum warpage or distortion 0.75%, other board warpage is generally not more than 1.5%; Electronic … Continued
Via-connection channel of double-layer board This is the most confusing part before. When you get a PCB, you will find that there are many small holes with the size of the needle tip. This is the via. Its structure is as follows. The function of the vias is mainly to connect the copper wires on … Continued
Learn how copper clad laminate grades affect PCB reliability, material selection, electrical behavior, thermal performance, and fabrication risk.
Review the key characteristics of PCB boards, including electrical performance, mechanical structure, thermal behavior, manufacturability, and reliability.
PCB production process, that is, printed circuit board production process. Almost every electronic device, ranging from electronic watches and calculators to large computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, printed boards are used for the electrical interconnection between them. In a larger electronic … Continued
Learn the main printed wiring board classifications, including rigid, flexible, rigid-flex, single-sided, double-sided, multilayer, and application-based PCB types.
Layout design In the PCB design, special components refer to the key components of the high-frequency part, the core components in the circuit, the components that are susceptible to interference, the components with high voltage, the components with high heat generation, and some heterosexual components , the position of these special components needs to be … Continued
Choosing high-frequency and high-speed PCB materials requires review of dielectric loss, impedance, stackup, copper roughness, thermal behavior, and supplier capability.
The design of the printed circuit board is based on the circuit schematic diagram to realize the functions required by the circuit designer. The design of the printed circuit board mainly refers to the layout design, and the layout of external connections needs to be considered. Various factors such as optimal layout of internal electronic … Continued
The meanings and characteristics of these three holes for circuit board. Conducting holes (VIA), a common type of hole used to conduct or connect copper foil lines between conductive patterns in different layers of a circuit board. For example (such as blind holes, buried holes), but can not insert component lead legs or other reinforced … Continued
Strong PCB design starts with clear electrical intent, manufacturable layout, and assembly-aware review before board release.
