pcb substrate material
1. Phenolic PCB paper substrate Since this PCB board is composed of pulp and wood pulp, it sometimes turns into cardboard, V0 board, flame retardant board and 94HB. Its main material is wood pulp fiber paper, which is a PCB made of phenolic resin. board. Characteristics The paper substrate is not fire-resistant, can be perforated, […]
Difference between single and double-sided PCB boards
The difference between a double-sided PCB board and a single-sided PCB board is that the single-sided PCB circuit is only on one side of the PCB board, while the double-sided PCB circuit can be on both sides of the PCB board, with a via in the middle to double-sided PCB board. The lines are connected. […]
Is PCB harmful to human body?
We always thought that PCB was just a component in electronic products, but we never thought about whether it would cause harm to human body. PCB was discovered in the 19th century. At that time, cars began to be widely used, and people’s demand for gasoline increased. Gasoline is refined from crude oil. During the […]
What to pay attention to in PCB design
n PCB design, when PCB mass production is finally carried out, PCB assembly is also a very important thing. This not only involves the quality standards of PCB circuit boards, but also affects the cost of PCB production. How to make a reasonable and effective jigsaw on the premise of ensuring the quality of the […]
What is pcb puzzle
What is the definition of pcb puzzle The pcb jigsaw is only for production convenience. For the board manufacturer, his substrate is generally relatively large. Many boards are made at one time and then cut out one by one. If the jigsaw is mainly used for welding production, Imagine a board with large fingernails one […]
Advantages of aluminum PCB and application of LED aluminum PCB
It has a thermal cladding to efficiently dissipate heat while cooling components and improving the overall performance of the product. Advantages of aluminum PCB 1. Environmental protection: Aluminum is non-toxic and recyclable. Due to its ease of assembly, the use of aluminum also helps to save energy. For printed circuit board suppliers, the use of […]
What is a Multi-layer PCB? Multi-layer PCB and its advantages?
Printed circuit boards are now the most important entity in electronics. PCBs used in the past were very simple and limited to a single layer. Today’s PCBs are complex and are called multilayer PCBs. Those PCBs with limited functionality are single-layer, while those with multi-function PCBs are composed of multiple layers. Compact PCB for motherboards […]
What are the high frequency PCB
Definition of PCB high frequency board High frequency board refers to a special circuit board with a high electromagnetic frequency. It is 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). Part of […]
Design method of PCB shape and size
The PCB shape and size are determined by the PCB transmission method and placement range of the placement machine. 1.PCB shape (1) When the PCB is positioned on the mounting table and the PCB is transmitted through the table, there are no special requirements for the shape of the PCB. (2) When the PCB is […]
What is a PCB? What does the PCB include?
There is a key component in the electronics industry called a printed circuit board (PCB). This is a too basic part, making it difficult for many people to explain exactly what a PCB is. This article will explain in detail the composition of PCB and some terms commonly used in the field of PCB. In […]
