The size of LED board circuit
The LED board circuit requires more and more small size.
Now most of electronic products have become smart and small.
In LED lighting industry also have the same require, result of PCB board manufacturers have to produce small size PCBs.
The temperature of LED board circuit
The head dissipation problem due to small size LED board circuit.
Small LED lighting not only require smaller size, but also requires better heat dissipation performance.
Because of the trend towards miniaturization, thermal output per surface unit is increasing, which means that ever increasing heat is emitted onto an ever smaller surface area for dissipation.
