Flexible Printed Circuit or FPC is way durable and reliable. It is used in the field of aviation besides serving the purpose in calculators, printers, and cameras as well as in satellites. FPC Manufacturer China is some of the well-known manufactures in industry.
The constituent of the flexible printed circuit is a metallic layer of traces, more commonly copper. These get bonded to a dielectric layer that is common time. In terms of thickness, the metal layer can either be very thick or very thin but the thickness of the dielectric layer will be uncertain.
Now, for the multi-layer PCB, it is a board that has over two layers. Each multilayer PCB must have three layers of conductive material at the least. This conductive material is legit buried in the center of the material.
The production of multi-layer PCB involves alternating layers of epoxy-infused fiberglass sheets known as prepreg. The lamination of the conductive core materials takes place after that and it is done under high temperature as well as pressure. It is done using a hydraulic press. In the case of a Multilayer PCB Manufacturing Company China has few companies where the production of such multi-layer PCB takes place.
To understand whether or not the PCB is multilayer, you need to notice whether or not there is any place on the board with any sort of planes on the visible, outer layers. If you are unable to see any light through it, chances are that it is probably copper.
