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.

Heavy Copper 4oz 140um PCB 4 Layer 2.0mm Green Soldermask ENIG
Linked Electronics Co., Limited is a PCB prototype manufacture in China.
For PCB copper thickness 1oz=35um. There is no conclusion about the definition of heavy copper PCBs in IPC standard. And at Linked, for PCB copper thickness which is more than 2oz=70um is heavy copper PCBs. These heavy copper PCBs are used for large (high) current outputs and for optimization of the thermal management. The thick copper allows large PCB-cross-sections for high current loads and encourages heat dissipation. The most common designs are multilayer or double-sided. With this PCB technology it is also possible to combine fine layout structures on the outer layers and thick copper layers in the inner layers.
And heavy copper electronic PCB board produced by Linked Electronics are widely used in the following products, such as solar power converters, torque controls, UPS systems, safety and signal systems
rail traction systems ,power line monitors, protection relays, HVAC systems, storage pumping plants and overload relays.

Quality Assurance of the PCBs Produced by Linked Electronics
1. Linked Electronics has a very strict quality inspection systems, which follows the IPC Class 2 standard or IPC Class 3 standard
2. All PCBs are 100% e-tested by AOI and flying probe or fixture
3. Besides e-test, there is other test, such as thermal stress, microsection, solderability test and so on.
And our FQC team will carry 100% visual test to found out any possible PCB issues such as board warp and twist, offsite of soldermask, board thickness tolerance etc.
4. At Linked Electronics, we have constant quality standard which help us to win a lot of customers around the world.
