Do you know the thermal efficiency of LED PCB board manufacturers?

Do you know the thermal efficiency of LED PCB board manufacturers?
Yes, the thermal efficiency of LED PCB board manufacturers has some difference.

If you have known the PCB manufacturing precision, you can understand this point more clear.
Advance technology has magnitudes higher thermal efficiency than even the very best MCPCB in the market.
Or the LED PCB board manufacturers can’t produce the best performance for you.
You know MCPCB is available with Aluminum base PCB metal or Copper base metal.
Even some LED PCB board manufacturer, use difference material to produce MCPCB board, also have some performance difference.

Three PCB type heat transfer rate compare

Difference LED PCB board has difference heat transfer rate.
Here is a list of normal PCB manufacturers heat transfer rate.
Aluminum based PCB can transfer heat at the rate of 210.0 W/m.K
Copper based MCPCB can transfer heat at a rate of 385.0 W/m.k.
Conventional MCPCBs have a heat transfer rate of 1-5 W/m.k.
