In the short term, the copper clad laminate industry is in a price increase cycle, and the downstream demand boom drives the company's single-quarter profit margin upward. In the medium and long term, the PCB industry's supporting facilities will force upstream domestic manufacturers to expand production. In 2020, the year-on-year growth rate of capital expenditure of PCB listed companies will return to a high level. A new era.
Currently widely used PCB sheet is copper-clad / epoxy glass cloth substrate or phenolic resin glass cloth substrate, and there are a few paper-based copper-clad sheets used. Although these substrates have excellent electrical performance and processing performance, they have poor heat dissipation. As a heat dissipation route for high heat-generating components, the PCB itself can hardly be expected to conduct heat from the resin of the PCB, but to dissipate heat from the surface of the component to the surrounding air. However, as electronic products have entered the era of miniaturization of components, high-density installation, and high-heat assembly, it is not enough to rely on the surface of components with very small surface area to dissipate heat. At the same time, due to the heavy use of surface-mounted components such as QFP and BGA, the heat generated by the components is transferred to the PCB board in large quantities.
Since 2019, the global deployment of 5G base stations will be accelerated, and the first year of the 5G era will begin. The demand for communication base stations in the new era has risen sharply, and it has flourished the related parts industry chain. The PCB industry chain is one of the popular fried chickens.
There are different Quality Class Standards in the industry. Most commonly followed is class 1 & 2.
Class 1 is for General Electronic Products and for testing and verification of Designs.
Class 2 is for Dedicated Service Electronic Products such as communication equipment,sophisticated business machines, instruments where high performance and extended life is required and for which uninterrupted service is desired.
Class 3 products are used in certain types of medical, aeronautics, and military applications for which uninterrupted and high reliability service is required.
