It is critical for board designers to lay out their boards to create the best possible signal and power integrity. Components shall be placed in a good position for short and direct wiring. At the same time, the boards must be laid out so that all the net
manufacturing technology and system complexity and other key factors have many conflicting requirements, PCB board laminated design is generally considered in various aspects of the key factors after a compromise decision. High - speed digital circuits an
Poor insulation of copper wire will lead to arc between copper wire and copper wire. Too close between the copper trace and the path, it is easy to short-circuit risk; The lack of thickness of the circuit board can lead to bending and breaking.
it is necessary to pay attention to the maintenance order so as to find the shortest path to solve problems, so as to avoid poking and dismantling randomly, which will fail to repair and otherwise lead to greater faults.
If there are a lot of key signals on the PCB to do impedance, you can attach a separate document, will be impedance control line display, and explain the value and error to do, circuit board factory will adjust the control of these "important signal&...
high speed circuit design technology has become the electronic system designers must take the design means. The controllability of the design process can only be achieved by using the design techniques of high speed circuit designers.
n electronic product that does not conform to EMC specifications is not an acceptable electronic design. In addition to meeting market functional requirements, design products must also adopt appropriate design techniques to prevent or relieve EMI effects
In practical EMI shielding, the electromagnetic shielding efficiency depends largely on the physical structure of the chassis, namely, the continuity of conduction. The seams and openings in the chassis are leakage sources of electromagnetic waves.
Here, it is temporarily classified into two categories: one is electrical related safety spacing, one is non-electrical related safety spacing.
After the circuit is completed, solder resistance ink is coated on the circuit as protection of the circuit. There are liquid photosensitive, heat curing and UV hardening.
Our electronic products are often more than 60% - reliability problems are in the PCB design of the electronic circuit board; Relevant theoretical and practical experience is required for working and performing PCBS;
In the high-speed era, the ideal wiring on any section of schematic diagram has become an unsatisfactory wiring on PCB, bringing a variety of unexpected high-speed problems. Therefore, PCB engineers also need to accumulate experience and theoretical knowl
