What is the difference between a double-layer pcb circuit board and a single-sided pcb circuit board

What is the difference between a double-layer pcb circuit board and a single-sided pcb circuit board? The staff of the circuit board manufacturer will introduce it to you.

      1. Looking at the light, the inner core is opaque, that is, it is completely black, which is a multi-layer board. On the contrary, it is a single-sided circuit board. The single-sided circuit board has only one layer of wiring, and there is no copper in the hole. There are traces on both sides of the double-sided circuit board, and there is copper in the vias.

How to distinguish between double-layer pcb circuit board and single-sided pcb circuit board

      2. The most fundamental difference is the number of routing overlays:

      The single-sided PCB circuit board has only one layer of wiring (copper layer), all holes are made of non-metallic materials, and there are no electroplating process steps;

      The two-layer pcb circuit board has a double-layer route (copper layer), metallized holes and non-metallic materialized holes, and electroplating process steps.

      3. PCB circuit boards are divided into single-sided pcb circuit boards, double-sided pcb circuit boards and multi-layer pcb circuit boards. Multilayer pcb circuit board refers to a pcb circuit board with three or more superimposed layers. The processing technology of multi-layer pcb circuit boards is basically a manufacturing process of single and double-sided circuit boards plus internal pressure lamination. Analysis can also be performed by using slices for distraction.

      The above is to tell you the difference between a double-layer pcb circuit board and a single-sided pcb circuit board. If you have any questions about this, please come to us.
