What knowledge of PCB design?
PCB design engineers need to master a wide range of knowledge system, including electrical theory, component performance, digital circuit and analog circuit, PCBA processing process and DFM manufacturability theory, schematic drawing and Layout.
PCB design, how to choose the power chip?
PCBA refers to a machining process, and the process on PCB board has been completed before it is calculated as PCBA. PCB refers to a blank printed circuit board without any parts, that is, PCBA is a finished board, PCB is a bare board.
PCB design skills of switching power supply
In any switching power supply design, the physical design of the PCB board is the last link. If the design method is not correct, the PCB may radiate excessive electromagnetic interference, causing the power supply to work unstable.
How to avoid HDI PCB design problems?
Maintain the integrity of signal transmission and prevent the "ground projectile phenomenon" caused by the division of ground wire.
Antistatic discharge method for PCB design
When PCB is assembled, do not apply any solder to the top or bottom pad. Use screws with built-in washers to achieve tight contact between the PCB and the metal case/shield or ground surface bracket.
How to improve Bluetooth PCB design
Printed circuit boards using Bluetooth technology may experience interference, data loss, and poor signal integrity if certain precautions are not taken.
What are the PCB design problems
What are the features of SMT processing BGA assembly: 1, the BGA pin (welding ball) is located under the package body, 2, before mounting must confirm whether it meets the process requirements, 3, in the PCB design should be as far as possible to lay it a
60K multi-PIN power communication board PCB design case
which is equivalent to reviewing the schematic diagram, modifying the scheme for design, and si simulation at the same time. There are many types of power supply with small voltage and large current on the board.
PCB design: Quick estimation of resistance value of wire
The most important material for printed circuit boards is copper, from which most boards are made.

Communicate electronic devices. Military weapon system, as long as there is integrated circuit and other electronic devices, electrical interconnection between them to use PCB, circuit board.
Crosstalk in PCB design
The simultaneous dumping of current underground may temporarily raise the ground's electrical potential, causing a change in reference, a phenomenon known as ground rebound. The main conditions that affect grounding bounce include load capacitance, socket
