The Significance and Design Difficulties of PCB Copper Coating
The significance of copper coating is to reduce the ground impedance and improve the anti-interference ability. Reduce voltage drop, improve power efficiency.
PCB Design Considerations For Switching Power Supply
Review according to PCB checklist, including design rules, layer definition, line width, spacing, pad and hole Settings, focusing on the rationality of device layout.
High-speed PCB design and routing method to solve signal crosstalk
Adopt shielding measures providing packet ground for high speed signal is an effective way to solve crosstalk problem.
How does PCB design determine the number of PCB layers?
When deciding the number of PCB design layers, the following issues should be taken into account: 1Where will the PCB be used? PCBS are used in various types of simple to complex electronic devices. Therefore, the first thing to figure out is whether the
How to prevent sheet copying through PCB design?
The patch pin accurately detects the area of the pad contact pin to avoid affecting the welding 7. Through hole pinAccurately detect the hole size and number of attributes of the through hole pin to avoid the purchase of components cannot be used 8. Press
PCB design from a soldering perspective
For circuit boards with components on both sides, consider that the second reflow soldering will wipe off the components on the soldered side.
How to protect multi-layer PCB edge radiation through PCB design?
First of all, we must optimize the key signal wiring on the PCB to avoid EMI problems, more than the layer change hole, we can punch a ground hole around the key signal hole to provide additional return path for the key signal hole
