Only when the digital signal is routed on top of the analog portion of the circuit board or the analog signal is routed on top of the digital portion of the circuit board will the interference of the digital signal to the analog signal occur.
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.
What problems should we pay attention to in PCB laminated design? Let a professional engineer tell you. Two rules must be followed in the design of lamination
Generally speaking, many engineers pay more attention to forward crosstalk, but this is the wrong thinking.
Many engineers who are responsible for Process or SMT technology in the factory will often come across solder empty, de-solder or cold solder of the circuit board components and other non-solder problems.
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.
The choice of surface treatment process mainly depends on the type of final assembly components; The surface treatment process will affect PCB production, assembly and final use.
The purpose of the surface treatment is to ensure good solderability or electrical properties. Since copper tends to exist in the air as an oxide and is unlikely to remain as raw copper for long periods of time, other treatments of copper are required.
