What is a Double-side PCB


The double-sided PCB is a common type of printed circuit board. It has wires and components on both the front and back sides, and the double-sided PCB boards are connected with vias in the middle. The double-sided printed circuit board has two upper and lower conductor patterns, and the upper and lower via holes are connected by expensive perforations. In the processing of printed circuit boards, the hole walls of your perforated holes are coated with a copper layer to make the upper and lower layers conductive. Double-sided printed circuit boards are usually double-sided copper-clad laminates, using screen printing or photo imaging. A resist pattern is formed on the copper surface, and excess copper foil is removed by chemical etching to form a conductor pattern.

Steps to draw double-layer PCB board


1. Prepare the circuit schematic
2. Create a new PCB file and load it into the component package library
3. Planning the circuit board
4. Load the netlist and components
5. Automatic layout of components
6. Layout adjustment
7. Network density analysis
8. Wiring rule setting
9. Automatic wiring
10. Manually adjust the wiring
After the components of the double-layer PCB are drawn in the EDA software, the wiring sequence is first designed as power line, sensitive line, high frequency line and low frequency line. It is best to have a separate power supply for the key lead, a ground return, and the lead is very short, so sometimes a ground wire is placed close to the signal line on the edge of the key lead to make it form the smallest working loop.

The signal lines of the double-layer PCB board are the key crystal, crystal oscillator circuit, clock circuit, CPU and other signal lines, which must comply with the principle that the circulating area is as small as possible.
