In the current PCB design, engineers usually need the impedance control for the chips, in the industry, it includes 3 types impedance : single end impedance (usually 45 ohm or 50 ohm), differential pairs impedance(usually 90 ohm or 100 ohm) , coplanar(usually 50 ohm or 90/100 ohm)
With our electronic equipment increasingly becoming smaller, PCB prototyping is increasingly becoming more and more complex.
Printed Circuit boards vary in size and composition depending on their application
This includes information such as component references, company logos, component identifiers and more
To be PCB a trader with good performance, as we all known, you must be a good negotiator, negotiate with your customer to make a deal with reasonable profit
A printed circuit board, or PCB, is used to mechanically support and electrically connect electronic components usingconductive pathways
Before 2000, the output value of the global PCB 70% mainly in Europe, America, Japan, Korea and other countries.
