Multilayer circuit board factory: Introduction to the production process of multilayer circuit board
As electronic products require more and more functions, the structure of multilayer circuit boards is becoming more and more complex. Due to the space limitations of multi-layer circuit boards, circuit boards are gradually "evolving" from single layer to double layer to multilayer. So what is special about the manufacturing process of multilayer circuit boards?
Multilayer circuit board is a kind of printed circuit board, which is made by lamination and bonding of conductive pattern layer and insulator. The number of layers of the conductive pattern is more than 3, and the electrical interconnection between the layers is realized through metallized holes. The double panel is the inner layer, the two single panels are the outer layer, or the two double panels are the inner layer. If two single panels are used as the outer layer, they are combined with each other through the layout system and the insulating bonding material, and according to The design requires that the conductive patterns are connected together, which will become a 4-layer or 6-layer printed circuit board, also known as a multilayer PCB circuit board.
