Heavy Copper Rigid Pcb Board 4oz 140um PCB 4 Layer 2.0mm Green Soldermask ENIG

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.

If you have any heavy copper request, contact our team and we are happy to quote your heavy copper PCB RFQs.

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.
