From the current situation, only our country has recovered the supply of products in a short time, accelerating the trend of domestic replacement of PCB industry.
Now PCB proofing factories generally provide expedited service, such as 12 hours, 24 hours expedited delivery; Usually the normal delivery time of single and double panels is 2 days.
Before PCBS, circuits were made up of point-to-point wiring. The reliability of this method is very low, because as the circuit ages, the rupture of the line will cause the line node to break or short.
Almost every kind of electronic equipment, from small electronic watches and calculators to large computers and communication electronic equipment, as long as there are electronic components such as integrated circuits, in order to make the electrical int
In order to meet different market needs, pcb board manufacturers can open these different forms of files. Then, what materials need to be prepared before pcb board proofing? Follow long Bo technology to understand!
Anti-interference directly reflects the performance and reliability of the whole system. For PCB design engineer, anti-interference design is the key and difficult point that we must master.
Therefore, pcb manufacturers believe that when designing or reinforcing equipment, they should be placed on PCB boards with higher hardness, or use certain methods to avoid pcba processing.
The size of PCB is limited by the capability of the equipment in the electronic processing line, therefore, the appropriate size of PCB should be considered in the design of the product system scheme.
From 4G upgrade to 5G, communication base station required PCB quantity and price rise. Due to the high-frequency microwave characteristics of 5G, the base station density is higher than that of 4G base stations.
The layout should meet the following requirements as far as possible: the overall connection should be as short as possible, and the key signal line should be the shortest; High voltage and high current signals are completely separated from low voltage, l
Wiring is the general requirement of high frequency PCB design on the basis of reasonable layout. Wiring includes automatic wiring and manual wiring.
Both schematic drawing and PCB design should be considered from the high frequency working environment in order to design a more ideal PCB.
