Quality Control of CESGATE Main PCBA
Main PCBA Application - Multilayer Board
Multi-layer board: The required circuits are made on the front and back surfaces of multiple double-sided boards, and an insulating layer (Prepreg) is sandwiched between the two double-sided boards and then pressed together to form several layers of copper. The construction of the wire is usually an even number of layers due to the use of multiple double-sided laminates. The number of copper wires that can be made by multi-layer boards is the largest, and it is used in more complex circuits. At present, the motherboards used in computers mostly use eight-layer boards because of too many components. Generally, small electronic products, such as mobile phones, tablet computers, etc. Due to the requirement of small size, at least an eight-layer board is required. The more electronic components, the smaller the product size, and usually more layers of Main PCBA are required.
1. Material
FR-4 (glass fiber epoxy resin substrate) is the most widely used material in the global electronics industry. FR is a code name for a flame-resistant material grade, which means a material specification that the resin material must be able to self-extinguish after burning. It is not a material name, but a material grade, so there are many types of FR-4 grade materials currently used in general circuit boards, but most of them are four-functional epoxy resin plus filler (Filler) and glass fiber. The composite material made. In recent years, due to the development of electronic product installation technology and Main PCBA technology, FR-4 products with high Tg have appeared again. Tg degree (glass transition temperature - Glass Transition Temperature)
