In circuits with resistors, inductors and capacitors, the obstruction to alternating current is called PCB impedance.
High frequency circuit board is a special circuit board with high electromagnetic frequency.
The terminal requirements of printed circuit boards can be divided into enterprise-class user needs and individual consumer needs
Commonly used SMD resistor values look-up table
Good WIP control to ensure PCB delivery time,and ensure the PCB manufacturing process is favoring.
PCB prototype, refers to a trial run before mass production of printed circuit board.
The PCB cost calculation of each plant is not the same, there is a simple method (lengthwidth square unit price), but also a complex method.
Reassuring pcba contracting manufacturing,China pcb circuit board manufacturing,provide with quality electronic processing services.
PCBA One-stop service, that is, customers provide all the information to the factory, the factory directly finish product assembly sending to the customer, the customer only need to test at the last.
In dozens of circuit board production process, set the key point of the IPQC, can avoid the error caused by the next process opportunity cost.
