How to distinguish between multilayer circuit board and single circuit board?
From the external point of view, both sides of the multilayer circuit board line, single-sided circuit board only one side of the line
General, a difference in the simplest way, up to the light, the inner core is opaque, that is all black, is multilayer, the contrary is single sided, single panel, only one line, there is no copper hole. Both sides of the double-sided board is a line, through the hole through the copper.
The circuit board is divided into single side circuit board, double side circuit board and multilayer circuit board, multilayer circuit board is to point to the circuit board of three and above layers. On the basis of single and double sided board, the production process of multilayer circuit board will be combined with the inner pressing process. Use slice distraction can also be analyzed.
