The first layer in the middle is laid with multiple GND, several lines can be laid, but do not divide each layer of copper; The second layer of VCC copper in the middle has multiple power supplies laid separately. A small number of lines can be laid, but
Base plate series - plywood (multilayer board）Physical classification:Generally divided according to the number of layers. The common ones are three plywood, five plywood, nine plywood, twelve plywood, eighteen plywood and so on. The number of layers of p
The above is the knowledge that optical module PCB and optical device cascade simulation need to master. Compared with chip packaging and board level PCB, there are a lot less things, and because there are a lot of repetitive things in optical module simu
Large scale, top ranking PCB enterprises mainly produce large batch board, PCB enterprises positioned in small batch board are relatively few, in addition to the company, the domestic production of small batch board representative enterprises mainly Chong
The number of layers of the multilayer board is not limited, there are more than 100 layers. Relatively speaking, PCB with even layers does have more advantages than PCB with odd layers.
PCB multilayer board is the multi-layer line layer, between each two layers is the media layer, the media layer can do very thin.
PCB multilayer board covered with copper laminate material. When quality problems occur in the actual manufacturing process, PCB laminate is the test item that must be carried out to cause the problems in the production process.
