Printed circuit board material types introduce

This post topic is PCB proto.
If you have read HTD circuits promotion flyers.
You must know that the promotion PCB types are main prototype.
This means we mainly to promote the PCB proto.

Today we are going to discuss about the material type of the PCB proto.
You know the PCB proto is very special type.
This not only it's delivery very fast.
But also the PCB proto material also very unique.
In fact this also this post aims.

So what is the PCB proto material?
In fact, There are many material types that can be used to manufacture a PCB.
That's the reason why so many kinds of PCB types. 
But the most common of which is called FR-4.
 
FR-4 is simply fiberglass and material woven together with an epoxy resin that includes fire-resistant properties.
You know the PCB board has one biggest require is fire-resistant.
So this also requires the PCB proto material also fire-resistant.

In fact there were many other kind types material to make PCB boards.
Other material types that could be selected include higher temperature FR-4, Polyimide, Hybrid Capable, High Copper Weight, Flex etc.
