1. Multilayer PCB Usage
Generally, the multilayer PCB is widely used in professional electronic
equipment like computers and military equipment, especially in the case of
the overload of weight and volume. The mltilayer pcb is also very useful in
high-speed circuit. The mltilayer pcb can provide more space for the
conductor pattern and power. Wonderful PCB (HK) LIMIITED, who has been
in PCB line for 16 years, is professional in Flex PCB & Rigid PCB prototyping,
PCB manufacturing, PCB assembling and stencil in China.
The multilayer PCB is made up by two or more pcbs which are stacked
together with reliable predefined mutual connection between them. There
are at least three conductive layers in one multilayer pcb with two layers
outside and the one layer synthetized in the insulation board. Due to the
complex manufacturing process and lower production , the cost of
multilayer pcb is relatively higher.
The outcoming of multilayer pcb results from requirements of the
development of electronic technology,such as high speed, multi-function,
high-capacity, small size. On one hand, as the electronic devices is
becoming smaller and lighter, single-sided pcb and double-sided printed
pcb cannot match increasing assembly density due to the limit of available
space. Therefore, the design of pcb must be committed to minimize the
length of the signal line and avoiding the parallel routes. Under the demand
of large number of interconnections and crosses, the multilayer pcb comes
onto the market. With the help of the state-of-the-art PCB manufacturing
equipment and the latest inspection equipment , Wonderful PCB can
manufacture close-tolerance multilayer PCB up to 32 layers.
At present, multilayer pcb has been widely used in various electronic
devices and it has become an important part among the electronic
components owing to its numerous advantages, such as high assembly
density, small size ,good quality; flexibility .
With the push of modern technology develops, it is recognized that the
multilayer PCB will be used in more fileds. Meanwhile, the request for
multilayer PCB will be more strict.
