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 silk screen position number does not determine whether the final patch is correct. Many experienced engineers found that deleting the bit number silk screen printing, PCBA product patch back and no problem. Generally, the machine patch locates the dev
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.
Solutions to impedance discontinuity problems in PCB design: 1. Gradient line, 2. Corner, 3. Large pad, 4. Through hole, 5. Through hole coaxial connector
As an electronic engineer design circuit is a necessary hard work, if the PCB design is not reasonable performance will be greatly compromised.
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
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
There are three PCB design methods that can withstand 100A current：1: PCB wiring, 2: terminals, 3: custom copper bar, 4: special process
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
Considerations for PCB design are analyzed below: from schematic creation of component parameters to PCB design process -> Input schematic netsheet -> Design parameter setting -> Manual layout -> Manual wiring -> Verify the design -> Aud...
The method of high-speed PCB design and wiring to solve signal crosstalk: First, in possible cases to reduce the signal along the conversion rate usually in the device, while meeting the design specifications as far as possible to choose slow devices, and
For you to analyze the common rules of thumb in PCB design wiring: first, vertical wiring, second, heat dissipation hole, third, right Angle wiring
