Our printing circuit boards include 2-28 layers, high TG, heavy copper, high frequency, mixed-dielectric laminate and buried & blind via board.
What Is PCB Board
Small printed circuit boardis one of the important parts of the electronics industry. Almost every kind of electronic equipment, from electronic watches to computers and military weapon systems, as long as there are electronic components such as integrated circuits, PCB circuit boards must be used in order to make electrical interconnections between the various components.
The PCB printed circuithas good product consistency, and it can adopt standardized design, which is conducive to the realization of mechanization and automation in the production process.
The reason why PCB products can be used more and more widely is because it has many unique advantages, which are roughly as follows:
High-density
Over the years, the high density of printed boards has been able to develop correspondingly with the improvement of integrated circuit integration and the advancement of mounting technology.
Testability
A relatively complete test method and test standard have been established. Various test equipment and instruments can be used to detect and appraise the eligibility and service life of electrical PCB products.
Maintainability
Since PCB products and various components are assembled in a standardized design and large-scale production, these components are also standardized. Therefore, once the system fails, electrical pcb board can be replaced quickly, conveniently and flexibly, and the system can be quickly restored to work.
What Are PCB Board Made Of?
Substrate
Insulating laminate composed of polymer synthetic resin and reinforcing material can be used as the substrate of copper clad laminate. There are many kinds of synthetic resins, commonly used are phenolic resin, epoxy resin, polytetrafluoroethylene and so on. Reinforcement materials generally have two types: paper and cloth, which determine the mechanical properties of the substrate, such as solder dip resistance and bending strength. According to raw materials, there are usually
Paper substrate: a. The blue HB is a non-repellent fuel; b. The red HB is a fuel-repellent fire rating of 94v0.
Semi-glass fiber material: a, 22F b, CEM-1 c, CEM-3, also known as imitation FRA
Full glass fiber material: What is the inner fiber content of FR1, 2, 3, 4, and FR4 is commonly used.
CopperFoil
The key material for the manufacture of copper-clad plates must have high conductivity and good weldability. According to ministerial standards, the nominal series of copper foil thickness are 18, 25, 35, 70 and 105um. my country is currently gradually promoting the use of 35um thick copper foil. The thinner the copper foil, the easier it is to etch and drill, which is especially suitable for manufacturing high-density printed boards with complex circuits.
Claim:
There must be no scratches, sand holes and wrinkles on the surface of the copper foil
Metal purity is not less than 99.8%
The thickness error is not more than ±5um
Requirements
The adhesive is an important factor in whether the copper foil can be firmly covered on the substrate. The peel strength of the copper clad laminate mainly depends on the performance of the adhesive. 4. Board thickness: usually refers to the requirements of the finished product, respectively, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.6mm, etc
