What are the advantages of a four-layer circuit board multi-layer board
For the most basic circuit boards, the components are concentrated on one side, and the wires are concentrated on the other side. Because only one side can be routed, we call this kind of circuit board a single panel. Both sides of the double panel can be wired, so the wiring area is twice as large

How long is the storage time of the four-layer circuit board
How long the circuit board is stored depends on the surface treatment. Gold and electroplated gold are the longest. They can be stored for two or three years under constant temperature and humidity conditions. Followed by tin spraying and oxidation resistance. Especially for anti-oxidation, it is be
