PCB design based on PCB design software can also be regarded as a software development process. Software engineering pays most attention to the idea of "iterative development" to reduce the probability of PCB errors.
PCB design, not only technology, but also art, art involves a lot of subjective factors, so engineers should also pay attention to improve their own culture.
The circuitry on the circuit board is designed to bend to ensure the stability of the signal. Circuit board design is a kind of technical work, only using the corresponding design to ensure the stability of the signal.
In PCB board backwelding furnace prone to plate bending and plate warping, we all know, so how to prevent PCB board backwelding furnace plate bending and plate warping.
The test circuits are based on a microstrip transmission line structure with a through-hole in the middle of the circuit used as a conductor and signal transition from the top copper layer of the dielectric substrate material to the bottom copper layer.
At present, our company through a large number of experiments, choose different types of ink and viscosity, adjust the pressure of screen printing, basically solve the hole hole and uneven, has adopted this process for mass production.
One end of the triangle is connected to a signal wire and the other is connected to ground. When static electricity is present, a tip discharge is generated which consumes electrical energy.
The trial-production process of six types of modules generally carried out by domestic counterparts is mainly after determining the main circuit, designing the compensation circuit, carrying out a large number of scheme design and sample production.
From the point of view of function, the hole can be divided into two categories: one is used as an electrical connection between the layers; The second is used for fixing or positioning devices. In terms of technological process, through holes are general
Vertical refers to the component body perpendicular to the circuit board installation, welding, its advantage is to save space, horizontal refers to the component body parallel and close to the circuit board installation, welding, its advantage is that th
They not only play a conductive role in the design, but also play the role of heat conduction, its thermal conductivity and heat transfer area are relatively large circuit board is an indispensable part of the electronic circuit, its structure is composed
General simulation software cannot take into account some impedance discontinuity wiring conditions due to the line model or the mathematical algorithm used. In this case, only some Temninators, such as series resistors, can be reserved on the schematic d
