LAM 810-225420-002 - Semicondutor Circuit Board

Description

PCB is short for Printed Circuit Board (Printed Circuit Board). Also known as printed circuit board, printed circuit board, because it is produced by electronic printing, it is called "printed" circuit board. A printed circuit board is a substrate for assembling electronic parts, and is a printed board that forms point-to-point connections and printed components according to a predetermined design on a common substrate. The main function of the product is to make a variety of electronic components form a predetermined circuit connection, play the role of relay transmission, is the key electronic interconnection of electronic products, known as the "mother of electronic products". As a substrate and key interconnect for electronic parts loading, PCBS are required for any electronic device or product. PCB characteristics and classification as well as upstream and downstream PCB features high density, high reliability, designability, producibility, assembly and maintainability of six aspects.

In general, the more complex the function of the electronic product, the longer the loop distance, the more the number of contact pins, the more the number of layers required by the PCB, such as high-level consumer electronics, information and communication products; The soft board is mainly used in products that need to be bent: such as notebook computers, cameras, automotive instruments, etc. PCB classification according to the number of layers, can be divided into single panel (SSB), double panel (DSB) and multi-layer board (MLB); According to the softness, it can be divided into rigid printed circuit board (RPC) and flexible printed circuit board (FPC). In industrial research, in general, according to the basic classification of PCB products, the PCB industry is subdivided into six major sub-industries, such as single panel, double panel, conventional multi-layer board, flexible board, HDI(high-density sintering) board, and packaging substrate. The PCB upstream industry includes PCB substrate board raw material suppliers and PCB production equipment suppliers, and the downstream industry includes consumer electronics, computers and peripheral products, automotive and mobile phone industries. According to the industry chain, it can be divided into raw materials - copper clad plate - printed circuit board - electronic product applications. The specific analysis is as follows: Glass fiber cloth: Glass fiber cloth is one of the raw materials of copper clad plate, made of glass fiber yarn, accounting for about 40% of the cost of copper clad plate (thick plate) and 25%(sheet). Glass fiber yarn is calcined into liquid state by silica sand and other raw materials in kiln, pulled into very fine glass fiber through a very fine alloy nozzle, and then twisted hundreds of glass fiber into glass fiber yarn. Copper foil: Copper foil is the raw material accounting for the largest proportion of the cost of copper clad plate, accounting for about 30%(thick plate) and 50%(sheet) of the cost of copper clad plate, so the price increase of copper foil is the main driving force for the price increase of copper clad plate. Copper clad plate: Copper clad plate is a product of glass fiber cloth and copper foil pressed together by epoxy resin and other fusion agents, and is the direct raw material of PCB. It is made into printed circuit board after etching, electroplating and multi-layer plate pressing.
