When designing HDI circuit boards, we should first follow IPC guidelines and standards. Four are specifically applicable to HDI circuit board design, as shown in Figure 1. IPC/JPCA-2315: This is an overview of HDI and provides a model for estimating the design density. IPC-2226: This specification educates users on micropore formation, wiring density selection, design […]
Carbon ink PCB refers to the PCB printed with carbon ink. Printing carbon ink is a relatively common surface treatment process, commonly used in single-sided and double-sided panels. Using screen printing technology, in the specified position printed on the carbon ink, after the oven curing test OK to form a qualified with a certain resistance […]
PCB side plating, also known as edge plating, is copper plating from the top to the bottom surface of the board and along (at least) one perimeter edge.PCB side plating reduces the likelihood of device failures by providing a strong connection to the PCB, especially for small PCBs and motherboards. Examples of this plating are […]
CCL, Copper Clad Laminate, also known as Copper Clad Laminate, is the upstream core material for PCB manufacturing and is closely related to PCB. The main material of PCB is Copper Clad Laminate (CCL), which is composed of substrate, copper foil, and adhesive, and its main functions are interconnection conduction, insulation, and support and adhesive, […]
1. What is Eagle PCB? Eagle PCB is a great PCB design software that provides advanced features such as online forward and reverse annotation, batch command execution script files, copper coating, and interactive following router. Open-source hardware is very popular in the creation world abroad. Many Open-source hardware are designed based on Eagle, and can […]
High frequency PCBs refer to a special type of PCB with high electromagnetic frequency, used for PCBs in the fields of high frequency (frequency greater than 300MHz or wavelength less than 1 meter) and microwave (frequency greater than 3GHz or wavelength less than 0.1 meter). It is a PCB produced on a microwave substrate copper […]
Polytetrafluoroethylene is known as the "plastic king", and polytetrafluoroethylene is known as the "plastic king". Roy Planckett, the father of fluororesin, developed it at DuPont in the United States in 1936. With the continuous development of 5G communication technology, the demand for high-frequency and low dielectric materials is also increasing. PTFE has excellent insulation and […]
FR-4 is one of the most popular materials used for manufacturing PCBs.FR in FR-4 represents a flame retardant, while the number 4 distinguishes this material from other materials in this category. FR-4 is a glass fiber reinforced epoxy laminate that looks like a thin woven fabric board. FR-4 also represents a grade used to manufacture […]
Nowadays, LED PCB is widely used and their technology is becoming increasingly mature. What is an LED PCB? As the name suggests, it is the process of soldering LED components onto a PCB, where the chip generates light during electrical connection. The heat sink and ceramic base are used to connect the chip to absorb […]
IPC-6012 is a performance document released by the Printed Circuit Association on managing PCB industry practices. IPC-6012 is a supplement to IPC-RB-276. Its scope includes the qualification certification and performance of rigid printed boards, which can refer to single-panel or double-sided boards with or without plated holes, multi-layer boards with plated holes, multi-layer boards with […]
Aluminum PCB is a metal-based copper clad board with good heat dissipation function, and the general single panel is composed of three layers of structure, which are circuit layer (copper foil), insulation layer and metal base layer. Aluminum substrate is a type of PCB board, and the design is designed in accordance with the requirements […]
S1000-2 is a high Tg material of PCB material type in Shengyi board. The relationship between S1000-2 and FR-4: FR-4 is a PCB material, also known as fiberglass cloth material. Compared with CEM and paper substrates, S1000-2 also belongs to FR-4 board in essence. The characteristics of the raw material S1000-2 are as follows: 1.High […]
