What is the general thickness of PCB board?

The thickness of a PCB is a critical parameter in the PCB manufacturing process, and it varies for PCBs used in different applications. Additionally, PCB thickness directly influences the performance, heat dissipation, and mechanical strength of electronic devices. So, how thick are PCBs usually? Let's delve into it!

The unit for PCB thickness is generally in millimeters. Typically, the standard thickness for PCBs is 1.6mm, meeting the requirements of most electronic devices and providing sufficient mechanical strength and heat dissipation. Other common thicknesses include 1.0mm and 2.0mm. PCBs with a thickness exceeding 3.0mm are commonly referred to as "thick boards" and are often used in industrial and military applications. On the other hand, those with a thickness below 0.8mm are termed "thin boards" and are usually employed in small or slim electronic products. It's important to note that these thickness specifications refer to rigid PCBs; if it's a flexible PCB, its thickness may be even lower.

In summary, the introduction above provides an overview of PCB thickness. It's worth noting that as the board becomes thicker or thinner, the manufacturing process becomes more complex, and correspondingly, the cost increases.
