Summary
multilayer pcb with quick turn service with 24 hours
multilayer pcb printed circuit board is from China pcb manufacturer with more than 10 years experiences
Multilayer PCB can be defined as a printed circuit board that has more than two copper layers, such as 4L, 6L, 8L, 10L, 12L, etc. Comparing to double-sided with two conductive layers of material, all multilayer PCBs must have at least three layers of conductive material, which are buried in the center of the material.
With the improvement and development of technology, people can put more and more copper layers on the same board. Currently, we,Shenzhen Kingfung PCB Factory, can produce 2L-30L FR4 MultiLayer PCB.
For example, there is a kind of multilayer PCB--12layer 2oz PCB Board layer stack up:
-----------------1.5oz L1
1080*2116 6.5mil
----------------- L2
| 0.18mm 2oz |
----------------- L3
1080*2116 6.5mil
----------------- L4
| 0.18mm 2oz |
----------------- L5
1080*2116 6.5mil
----------------- L6
| 0.18mm 2oz |
----------------- L7
1080*2116 6.5mil
----------------- L8
| 0.18mm 2oz |
----------------- L9
1080*2116 6.5mil
----------------- L10
| 0.18mm 2oz |
----------------- L11
1080*2116 6.5mil
-----------------1.5oz L12
Lamination thickness:1.9+/-0.15M
Compared to single or double-sided PCBs, multilayer pcb has many benefits, such as ：
1.Having higher assembly density
2.Having Smaller size (considerable savings on space)
3.Increasing flexibility
4.More Easier incorporation controlled impedance features.
5.Reducing the need for interconnection wiring harnesses
6.Reducing overall weight
