Detail the basic process of PCB design
The basic PCB design process is as follows: preliminary preparation →PCB structure design → mesh guide → rule setting →PCB layout → Wiring → routing optimization and silk screen → network and DRC inspection and structure inspection → output light drawing
The basic principles and requirements of PCB diagram design
The design of PCB starts from determining the size of the board. The size of PCB is limited by the size of the case shell, so that it can be placed into the shell exactly. Secondly, the connection mode of PCB and external components should be considered.
The six-layer PCB design is in line with EMC design
Solutions to impedance discontinuity problems in PCB design: 1. Gradient line, 2. Corner, 3. Large pad, 4. Through hole, 5. Through hole coaxial connector
The basic principles and requirements of PCB board drawing design
As an electronic engineer design circuit is a necessary hard work, if the PCB design is not reasonable performance will be greatly compromised.
What is the meaning of window opening in PCB design?
Four difficulties in the production and processing of multilayer circuit board: 1, the inner line production difficulties, 2, the inner layer between the point of difficulty, 3, pressing process difficulties, 4, drilling production difficulties
Design specification for Mark points in PCB design
SMT patch BOM list arrangement Note: 3. The description must be clear. 4. There are some crucial electronic components. Considering the fluctuations of the component market and the cost, 5. 6. Coordinate values required by coordinate T/B to distinguish po
PCB design wire and pad with white ring solution
There are three PCB design methods that can withstand 100A current：1: PCB wiring, 2: terminals, 3: custom copper bar, 4: special process
Can PCB design high speed signal layout be routed at 90°?
It is strongly required in various PCB design guidelines that high frequency and high speed signal transmission lines need to maintain consistent characteristic impedance, and that 90° Angle routing at the corner of the transmission line will change the l
Does pad size affect circuit board welding?
The circuit board software designed by many circuit board designers is designed according to the components of the circuit board software itself.
Why is it necessary to clean the circuit board after soldering?
The calibration shall be carried out by an approved standard measuring institution. The quality assurance department shall register the calibrated equipment, instruments and tools and keep a calibration record book.
