Multilayer PCB Board

  • High Precision Multilayer PCB Board suppliers

PCB, what we normal call as "printed circuit Board", is the basic for all electronics products. 

If we classify the PCB by layers, there will be single sided PCB, double sided PCB, and multilayer PCB Board.


Multilayer PCB Instructions by Linked Electronics


Multilayer PCB Board is made up of more than 2 copper layers, and those copper layers are boned by prepeg.  Conductor on different layers are connected with vias.

Compared with doubled sided layers, multilayer circuit board is smaller with higher capacity, faster speed, better durability and greater functionality. For BGA and QNF packages, electronic design engineer will use HDI multilayer PCB. 


By category in Linked Electronics, there are multilayer FR4 PCB, multilayer Rogers PCB, multilayer rigid flex PCBs, heavy copper multilayer PCB and HDI multilayer PCB board. 


Applications of Multilayer PCBs


Mulilayer PCB is used more and more in electronics industries becuse of its unique advantages.


Multilayer PCB boards is much more precise and has better performance than double sided PCBs, which is widely used in industrial, medical and communication industries.

Introduction toSemi Flex PCB



SEMI-FLEX is a flex to install PCB, typically it is a 4 layer PCB. And unlike the rigid flex PCB board, semi Flex PCB is made entirely of FR4. The semi flex is also different from conventional flex-rigid PCB’s. The flexing element is not polyamide but achieved by controlled-depth milling away the FR4 material in the bend area, so that it can be bent without cracking of on the area. 



Linked Electronics has been manufacturing and supplying semi flex electronics PCB boards for more than 5 years. Due to our high quality and reliable product performance, semi PCBs made by Linked Electronics are widely used in IoT, automotive and industry control products.



Advantages of Semi Flex FR4 PCB compared to FR4 PCB


1.Elimination of components


2.More cost effective than rigid flex PCB board


3. Space saving for the products


4. Light in weight






On the SEMI-FLEX PCB, there is a specific area which is flex to install. Unlike polyamide, the FR4 material  is not capable of bending too many times. However it can be bent for a limited number of times (typically 5-8 time) at a controlled radius and to any angle. This makes it an ideal solution where you need to mount two PCB’s into one unit at an angle to each other direclty without using connectors and cables or a rigid flex PCB. All this can be acheived in the semi flex PCB boards which is also much more cost effective than a traditional rigid Flex PCB board.
