Top three features of high heat circuit board
This paper is going to discuss the high heat circuit board.
As we know the high heat circuit board is a high end PCB board type.
The designers have squeezed ever more performance out of printed circuit board.
This means that high heat circuit board designers should consider high temperature applications in the first.
If you have know electronic theory, you may find this is difficult to finish.
So we will from some different factors to discuss the feature of the high heat circuit board.

The risk of high temperature circuit board application
As we know power densities can affect the product temperature.
Then the power densities are on the rise, the temperature also rises.
HTD PCB manufacture experts told us that the risk of high temperature can wreak component.
Not only the havoc on the conductors, dielectrics, but also the circuit board itself.
As consequence of high temperature, you should consider more during the design process.

The electronic performance of high heat PCB board
We have known the high temperature can affect components.
This means the temperature also affects thermal and electrical impedances.
During the elevated temperatures, those electronic impedances have bad performance.
Causing erratic system performance, until it outright fails.

High heat PCB have differences in thermal expansion rates
If you have learned some PCB manufacture process, you may know the thermal expansion is an important factor.
As well know it's a measure of the tendency of a material to expand when heated and shrink when cooled.
Its can be cause cracking and connection failures during PCB assembly process.
Between conductor and dielectrics generate mechanical stress.
By the the highest temperature PCB boards are subject to cyclic heating and cooling.
