Are Rigid PCBs Different From Flex PCBs?

Rigid PCBs are not completely different from flex PCBs. There are certain similarities between both PCBs as well. A major similarity between flex PCBs and rigid PCBs is the two PCBs perform similar functions. In addition, both PCBs are built in similar ways; nevertheless, flex PCBs make use of flexible circuit coverlay for protection, while rigid PCBs use solder masks for protection.

The manufacturing and designing of rigid PCBs slightly differ from flex PCBs. As a PCB designer or manufacturer, you must be careful when designing either PCB and ensure you follow the requisite design rules. These include minimum space, trace width, minimum hole size, design thickness, and several other factors.

A device can be designed with both PCBs In it. A laptop PC is a common device with both rigid and flex PCBs. Some parts of the laptop require rigid PCB for its functionality while the other parts require flex PCBs for the smooth and correct transfer of information.
