What Is PCB
Printed circuit boards for saleis 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 pcb printed circuit, small printed circuit board and large printed circuit board must be used in order to make electrical interconnections between the various components.
The blank copper pcb board and electrical pcb board has 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 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/blue pcb board 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 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, it can be replaced quickly, conveniently and flexibly, and the system can be quickly restored to work.
High reliability
Through a series of inspections, tests and aging tests and other technical means, the PCB can be guaranteed to work reliably for a long time.
Assemblability
PCB products are not only convenient for standardized assembly of various components, but also for automated and large-scale mass production. In addition, by assembling the PCB and various other components as a whole, larger parts and systems can be formed to the complete machine.
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
lPaper substrate: a. The blue HB is a non-repellent fuel; b. The red HB is a fuel-repellent fire rating of 94v0.
lSemi-glass fiber material: a, 22F b, CEM-1 c, CEM-3, also known as imitation FRA
lFull glass fiber material: What is the inner fiber content of FR1, 2, 3, 4, and FR4 is commonly used.
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:
lThere must be no scratches, sand holes and wrinkles on the surface of the copper foil
lMetal purity is not less than 99.8%
lThe 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
