How to Distinguish the Layers of Jiangmen Single-sided and Double-sided Circuit Board
Jiangmen single-sided and double-sided circuit boards can be divided into three categories according to the number of layers: single panel, double panel and multi-layer circuit boards.
First is the single panel. On the most basic PCB, the parts converge on one side and the wires converge on the other. Because the wires only appear on one side, the PCB is called a single-sided circuit board. Single panel is usually simple to manufacture and low cost, but the defect is that it can not be applied to too messy products.
Double panels are the extension of single panels. When single-layer wiring can not meet the needs of electronic products, it is necessary to use double panels. Both sides have copper clad wires, and can pass through holes to lead the lines between the two layers, so as to form the required network connection.
Multilayer board is a printed board which has three or more conductive graphics layers and insulating materials between them, and the conductive graphics are interconnected according to the requirements. Multi-information technology is developing towards high speed, multi-function, large capacity, small volume, thin and lightweight products.
How to distinguish between multi-layer circuit board and single-layer circuit board
1. Pick it up to the light, the inner core is opaque, that is, all are black, that is, multi-layer board, and vice versa, single and double panels, and single panels, as long as a layer of line, there is no copper in the hole. The double panels have lines on both sides, and the guide passes through the holes with copper.
2. The bottom difference is that the number of layers is different:
As long as a single layer of circuit board (copper layer), all the holes are non-metallic holes, no plating process.
Double circuit boards have two layers of lines (copper layer), metal and non-metal holes, and plating process.
3. Circuit boards are divided into single-sided circuit boards, double-sided circuit boards and multi-layer circuit boards. Multi-layer circuit boards refer to circuit boards with three or more layers. Multilayer PCB manufacturing process will be on the basis of single and double panels plus the manufacturing process of inner lamination, using slice distraction can also be analyzed.
