Alcanta PCB is a manufacturer of multilayer printed circuits. With years of experience in the field of printed circuit board manufacturing, you can be sure that Alcanta PCB is the name on which multilayer PCB and all PCB related requirements depend. We are good at order turnover speed, quality and value, which can not be matched by other PCB manufacturers. If you like the idea of PCB stacking in electronic applications using printed circuit boards, the only place where PCB stacking is needed is the Alcanta PCB.

It consists of a layer of dielectric material and a multilayer printed circuit board. When bonded to the board, these layers carry circuits that power a variety of household appliances, such as alarm clocks, kitchen appliances, desk supplies, computers and mobile devices. PCB is also used in a variety of industrial tools and machinery, medical equipment, government computers and storage systems, and aerospace equipment. The power distribution of PCB is determined by the number of layers and size of specific board.

What is multilayer PCB?

PCB layer is the decisive factor of PCB Power and capacity. People often wonder if a single PCB is enough, or if it’s best to use two or four layers – hint: there’s no such thing as a three-layer PCB – or something in the multi-layer range.

Although the number of layers depends largely on your budget and the functional requirements of the PCB, it does raise the question – what is a multilayer PCB? Basically, “multilayer” refers to anything with more than two layers, such as a 4-layer PCB or a range of 6-12 layers or more.

Complex multilayer PCB

When the number of layers of a multilayer printed circuit board increases to more than four and six, other layers of conductive copper and dielectric material are added to the stack.

For example, an eight layer PCB contains four planes and four signal copper layers – a total of eight – bonded together by seven rows of internal dielectric material. The top and bottom of the eight layer stack are sealed by a dielectric solder mask. Basically, the eight layer PCB stack is very similar to the six layer PCB stack, but has additional copper pairs and prepreg column pairs.

This trend continues to appear on 10 layer PCB, the latter added two layers of copper, forming a total of six signal layers and four plane copper layers, a total of ten layers. Nine rows of dielectric materials are bonded to copper in a 10 layer PCB stack – five prepregs and four cores. Like all other stacks, the ten layer PCB stack is sealed with dielectric solder mask at the top and bottom.

When you stack 12 layers of PCB, your circuit board has 4 planes and 8 signal conducting layers, which are bonded together by 6 signal layers and 5 core dielectric materials. The 12 layer PCB stack is sealed with dielectric solder mask. In general, multilayer PCB illustrations depict layers and bonding materials in the following colors – Brown for signal / plane copper, gray for prepreg / core dielectric, and green for top / bottom solder mask.
