How to Choose the Material Cost of PCB

Materials used during the manufacture of a circuit board will invariably affect/impact its cost. Standard or conventional PCBs are laminated using FR4 equipment. However, FR4 document doesn’t suffice for PCBs meant for high-intensity use, such as the ones that are common in fuel industries, aerospace, and control systems.


Some of the factors that are known to impact on the selection of material include thermal reliability, heat transfer, temperature reliability, mechanical properties, and signal performance. Right material used in the manufacture of PCBs must pass the above tests, a reason as to why the cost might be high than usual.


If the board has got the capabilities of withstanding high-intensity loads, then the cost of procuring them will be slightly costly than the rest. Still, if the circuit board can withstand a wide range of temperature changes, among others, expect them to be a bit expensive.


Boards with materials that can facilitate uninterrupted electrical signals while in operation in addition to withstanding a wide range of physical stresses will be costly. As a rule of thumb, activities that require higher frequencies will demand materials of a very high grade than the standard or conventional FR4.
