Double-layer pcb circuit boards and single-sided pcb circuit boards are widely used. So, how to judge the double-layer pcb circuit boards and single-sided pcb circuit boards?
1. Take it up to the light, the inner core is opaque, that is, it is all black, it is a multilayer board, on the contrary it is a single-sided circuit board, and a single-sided circuit board has only one layer of routes , There is no copper in the hole. The double-sided circuit board has a route on both sides, and there is copper in the guide hole.
2. The fundamental difference is that the number of route superimposed layers is different:
Single-sided PCB circuit board has only one layer of route (copper layer), all holes are made of non-metallic materials, no electroplating process steps
The two-layer pcb circuit board has a double-layer route (copper layer), with metalized holes and non-metal materialized holes, and electroplating process steps
3. PCB circuit boards are divided into single-sided pcb circuit boards, double-sided pcb circuit boards and multilayer pcb circuit boards. Multi-layer pcb circuit boards refer to pcb circuit boards with three layers and the number of superimposed layers above. The processing technology of multi-layer pcb circuit boards is basically the manufacturing process of single- and double-sided circuit boards plus internal pressure lamination. It can also be analyzed by using slices to distract.
The above is the judgment method of double-layer pcb circuit board and single-sided pcb circuit board. For more information on double-layer pcb circuit board and single-sided pcb circuit board, please contact Jingchuangda circuit board manufacturer.
