Fanyi PCB design Company to military quality PCB design requirement PCB design can not be arbitrary, there are certain rules. Fanyi circuit military quality PCB design has the following requirements
The Bonding line, C4 bump and solder ball connect the chip, package and PCB together. The whole power supply system should ensure that each integrated circuit device provides stable voltage within the normal range.
Another technique is to lay a ground wire between the two lines. The ground wire is low impedance, and adding such another wire will weaken the electric field that causes the interference!
The parallel computer technology of multi-CPU improves the computing speed of the system to a great extent, breaking through the limit of the processing speed of single CPU.
The crystal oscillator, as we often say, is the quartz crystal oscillator and the quartz crystal resonator.
In order to facilitate production, PCB circuit board plate generally needs to design Mark point, V groove, process edge.
Generally speaking, many engineers pay more attention to forward crosstalk, but this is the wrong thinking.
It can be said that pcb routing is the most important and time-consuming process in the entire PCB design. Here we share some pcb routing principles.
Isolation - Ensure that each circuit of power is kept power and control separate. If you must connect them together in the PCB, make sure it is as close to the end of the power path as possible.
It is essential to use high dielectric strength materials that can resist higher voltages before breakdown.
The milling technology of NC circuit board milling machine includes the selection of cutting direction, compensation method, positioning method, frame structure, the next cutter point, which is an important aspect to ensure the milling precision.
