Layout is one of the most basic skills of PCB design engineer. The quality of the wiring will directly affect the performance of the whole system, most of the high-speed design theory will be finally realized and verified by Layout.
How much is the temperature resistance of pcb circuit board? How to test the heat resistance of pcb circuit board? These are the customers often consult questions, the following to give you a detailed answer.
Once the embedded designer has determined the wire width and spacing, the number of wires to be routed through a channel, and the type of holes to be routed for the BGA layout design, he or she can estimate the number of PCB layers required.
Impedance circuit board Analysis of PCB circuit board impedance reasonspcb circuit board impedance refers to the resistance and reactance of the parameter, the alternating current plays an obstruction role. Impedance processing is essential in pcb circuit
The setting and connection of input and output circuits are very important for the whole printed FPC circuit board, and whether it is reasonable or not will directly affect the size of electromagnetic interference.
Gold is many times longer so everyone is happy to use it. Moreover, the cost of gold-plated PCB at the sampling stage is almost the same as that of lead-tin alloy plate.
Hongyunlai Electronic technology to give you the best quality SMT patch processing,PCB production, embedded system research and development, electronic processing, embedded motherboard,PCBA contract materials, Guangzhou PCBA processing services.
The internal network table is the network table used for wiring inside the PCB system after modification according to the imported external network table. Strictly speaking, these two types of network tables are completely different concepts, but the read
Formation mechanism: During reflow welding, the heating of chip components is heated at the same time. Generally speaking, the pad with the largest exposed area is first heated to a temperature above the melting point of the paste. In this way, one end of
The different types of structures are characterized as follows: 1: flexible single-sided printed board, consisting of only one conducting layer; 2: flexible double-sided printed board, consisting of two conducting layers. 3: Flexible multilayer printed bo
When the proofing is completed, we should carefully check to see if there are some problems in it. We must have a very appropriate check for the specific situation in advance and consider it in a targeted way. After these aspects, we can harvest better re
If you want to do these planning things well, you should have a correct understanding of the whole production process from a number of different angles
