What Is Multilayer Printed Circuit Board

What Is Multilayer Printed Circuit Board


Multilayer PCB is a Printed Circuit Board with more than two layers. Double-sided PCBs have two layers of conductivity on both sides of the PCB’s substrate. A multilayer PCB should contain at least 3 layers of conductive material or a copper layer. The layers are connected by copper-plated holes. The layers could be as long as 4, 6, 8…up to 60 layers.


The multilayer PCB can be intricate because of its design. The top and bottom sides appear identical to the double-sided PCB, but they have secured layers both on each side of the central layer. The layers are all compacted to create one PCB, which is multilayer which is joined by copper-plated holes.


JarnisTech manufactures multilayer PCBs from 4 -60 layers. In addition, we can take single-material or mixed-press materials Fr4, Rogers, Polymide, and metal Core. Please send PCB Gerbers files to [email protected], We’ll give you a quick quote!


What Exactly Are Printed Circuit Boards(PCB)


The printed circuit board (PCB) is an electronic device that makes use of copper conductors for electronic connections for components. The printed circuit board provides structural support to electronic parts so that they can be placed within an enclosure. The design of a printed circuit board requires a sequence of steps that is compatible with the process of manufacturing, the integrated circuit packaging, as well as the layout of the circuit board.


The majority of PCBs used for simple electronics are made of single sided or double sided ciruit board. Higher-end hardware like motherboards or computer graphics cards could need multi layers, sometimes as high as 60.


Multilayer PCB Substrate Material & Multilayer PCB Base Materials


It is possible to divide it into two types:


● PCB rigid substrate

● The flexible PCB is a substrate


Multilayer Rigid PCB Substrate


General rigid PCB substrate material is an important variety of copper clad plate. It is composed of Reinforein reinforced material which is dipped in resin adhesive through cutting, drying, forming into blanks, and finally painted with copper foil using a steel plate as mold using a hot press to perform high temperature and pressure forming. The most common multilayer board, with the semi-cured part is copper-clad sheet used in the manufacturing process of semi-finished goods (mostly glass cloth that is soaked in resin and processed through drying). Rigid PCB substrates include Aluminum PCB material that is bare, Ceramic PCB substrate material and metal core PCB material that is bare as well as FR4 bare materials and a special PCB substrate.
