Advantages of multilayer circuit boards
1, the multi-layer circuit board assembly density is high, the size
is small, with the volume of electronic products is getting smaller
and smaller, the function of PCB circuit board is also put forward
higher requirements, the demand for multi-layer circuit board is
also increasing.
2, the selection of multi-layer PCB circuit board laying line is
convenient, the length of the laying line is greatly shortened, the
laying line between the electronic components is reduced, but also
improve the data signal transmission rate.
3. For the high-frequency circuit, after entering the ground, the
signal line has a stable and low characteristic impedance to the
ground, and the characteristic impedance of the power circuit is
greatly reduced, which has a significant intercepting effect.
4. For electronic products with higher requirements for heat
dissipation function, metal core heat dissipation layer can be set
up on multi-layer circuit board, which is convenient to satisfy the
requirements of shielding, heat dissipation and other special
functions.
Why choose us
Price is only an indicator in the process of buying a product or
service. If you simply compare prices, it is not that thoughtful.
Price, quality, service, reputation, whether appropriate for their
own situation, etc., need to be considered together.
