Master these 10 tips and you too can become a PCB designer!
Many PCB manufacturers have to go through the network connection test of power-on before PCB processing is completed, to ensure that all the connections are correct.

High frequency PCB design: Factors affecting the performance of RF signals
This top view provides an example of installing a row of ground through holes in the top metal ground area on each side of the intermediate conductor. The circuit current caused by the top layer is short-circuited to the ground below.
How to deal with PCB sensitive circuit? What are the interference elements?
Compared with the microstrip, the ground coplanar waveguide circuit has the characteristic of low dispersion, and the radiation loss of the ground coplanar waveguide circuit is lower than that of the microstrip circuit when the frequency rises to the mill
High reliability PCB's 14 important characteristics
All of these problems can cause the solder shield to detach from the circuit board and eventually lead to corrosion of the copper circuit. Poor insulation characteristics can cause short circuits due to unexpected electrical connectivity/arcing.
Introduction to common PCB microporous technology
All of these problems can cause the solder shield to detach from the circuit board and eventually lead to corrosion of the copper circuit. Poor insulation due to thin solder resistance layer can cause short circuit due to unexpected conduction/arc.
PCB export business to the dark moment: cut order stack logistics encountered obstacles, turn to explore the domestic market
Based on the changes in the international trade environment, PCB industry is still under a big test, originally in the capital chain break and environmental pressure impact of small and medium-sized PCB manufacturers, are also accelerating out of the shuf
Why do photoelectric components on PCBS always fail?
PCB has become the most important and key part of electronic information products. Its quality and reliability level determine the quality and reliability of the whole equipment.
Manufacturing process of printed pcb
While this setup is tedious, it's not as bad as an auto-wiring device. Most design teams eventually establish a set of design rules that aim to: standardize bare board construction costs to maximize yield; Assemble, inspect, and test as consistently as po
pcb geometry and current
Unless the constraints of the auto-routing algorithm have been highly fine-tuned by the designer, the auto-routing results still need to be manually checked for weaknesses in the backtracking algorithm results.
Printed pcb design success of the seven technologies to be determined
The problem is clear. A technically correct but confusing schematic is still a bad schematic." Although this view is easy to accept, in CAD programs, an unreadable schematic diagram can still describe the circuit connection information, and is still ...
PCB board of 22 rules to share experience
That is: the actual out of the board is the circuit diagram to the right edge line as the reference line to the right after 180 degrees of the page. Pay special attention when there is a blank space! Otherwise the board is useless!
Common problems in PCB production and design
Therefore, welding resistance data cannot be generated directly from similar pad. When applying solder resistance, the filler block area will be covered by solder resistance, resulting in difficulty in welding components.
