Finished heavy copper pcb boards manufactured by Hemeixinpcb meet or exceed the performance

Release time: 27/12/2017

Finished heavy copper pcb boards manufactured by Hemeixinpcb meet or exceed the performance requirements of IPC-6011. There are three general end product performance classes that IPC-6011 has established. Class 1 is "general electronic products", Class 2 is "dedicated service electronic products" and Class 3 is "high reliability electronic products". Please see IPC-6011 or IPC-2221 for more information on the 3 classes. Hemeixinpcb requires all heavy copper pcb products to be class specified and any exceptions or additions to the specifications to be clearly indicated on the master drawings.

Thermal management is more important than ever today as electronics are used in demanding environments and operate at higher currents. Heavy copper PCBs (copper conductors 5 oz/ft² – 19 oz/ft²  in inner and/or outer layers; sometimes defined as more than 4 oz per square foot (ft²)) can help conduct heat away from components so failure is greatly reduced. PCB manufacturers create durable wiring platforms with heavy copper pcb . The resulting PC boards conduct electricity better and are more capable of withstanding thermal stress. These boards can be manufactured in a smaller footprint as they can contain multiple weights of copper on the same circuit layers.

The benefits of heavy copper pcb in PCBs include:

Reduction of thermal strain

Better current conductivity

Can survive repeated thermal cycling

Smaller PCB size due to layering of copper

Increased connector site strength

Depending upon the design requirement, heavy copper PCB is more expensive to produce than regular PCB. Hence, the more complicated the design, the more it will cost to produce a heavy copper PCB.
