Navigating the Terrain of Standard PCB Thicknesses: An In-Depth Guide

Thickness is a crucial component of printed circuit board (PCB) design that directly impacts its performance and use, and for anyone involved with designing, manufacturing or buying PCBs it is imperative that they understand norms and standards related to thickness – this parameter not only has an effect on electrical properties of the board but also impacts its durability, heat dissipation and physical fit within products or devices.

What are the standard pcb thicknesses? In terms of full, finished boards, the most commonly adopted thicknesses fall into three categories – 0.8mm, 1.6mm and 2.4mm.

1. 0.8mm Standard PCB Thicknesses:

This thickness level is more commonly seen in applications where space is at a premium and lightweight and compactness are essential, such as wearable electronics, slim-profiled devices or drone circuitry. Although thinner forms may prove helpful in certain circumstances, they could compromise durability over time and may require extra care when handling and assembly.

2. 1.6mm Standard PCB Thicknesses:

PCBs featuring 1.6mm thickness are widely adopted due to its combination of resilience and compactness, which make handling and servicing easier while being less susceptible to damage during manufacturing or servicing processes. 1.6mm standard PCB thicknesses makes an excellent choice for general consumer electronics applications as well as simple industrial circuits or educational electronics kits.

3. 2.4mm Standard PCB Thicknesses:

For applications that demand robust and durable PCBs, 2.4mm thickness boards are usually the go-to choice. Such PCBs can handle higher currents while providing better heat dissipation – however this extra thickness comes at the cost of increased weight and physical footprint.

Though these are the standard thicknesses of PCBs, it’s important to keep in mind that many manufacturers offer custom thicknesses. From ultra thin PCBs that measure as little as 0.2mm all the way up to sturdy boards with thicknesses around 3.2mm; manufacturers offer these custom thicknesses in order to meet specific industrial requirements such as high frequency applications or extreme environment electronics.

PCB thickness encompasses more than just overall board thickness; rather, its individual layers (copper layers and dielectric layers) also matter. A universally accepted measure for copper layer thickness for PCBs is 1 ounce per square foot – this typically corresponds to approximately 35 micrometers thickness.

Selecting the proper PCB thickness requires taking several factors into consideration. Not only must you take account of its application, manufacturing process and handling needs as well as product design considerations when making this important choice. No matter if it’s for a wearable device or space probe: selecting an optimal thickness can enhance performance, ensure seamless integration and increase longevity of your product.

As professionals in electronics, whether designing, developing, or simply admiring its wonders, understanding PCB thickness gives us a distinct advantage. By understanding standard PCB thicknesses and their applications, we become better informed decision-makers – helping our projects move towards excellence more successfully than ever! Here’s to creating sturdy yet efficient and robust PCBs one layer at a time!


  1. What is the standard pcb thicknesses?
    The most common thickness used for a standard PCB is 1.6mm (.063″). It is widely used across different applications, providing an ideal balance of performance and cost.
  2. Are there other standard pcb thicknesses?
    Yes, other standard thicknesses include 0.8mm (.031″), 1.0mm (.039″), and 2.4mm (.094″). The thickness used is specific to the requirements of the application.
  3. How is PCB thickness measured?
    PCB thickness is measured in millimeters or inches and includes the combined thickness of the base material and the copper layers.
  4. Why does PCB thickness matter?
    The thickness of a PCB can influence its rigidity, weight, and thermal performance. Depending on the application, these factors can be crucial to the final product’s operation.
  5. Can I order a custom thickness PCB?
    Yes, many PCB manufacturers offer custom thicknesses to meet specific design requirements. Keep in mind though, custom specifications may increase the cost and production time.
  6. What is the thinnest PCB available?
    The thinnest commonly available PCBs are around 0.2mm (.0079″) thick. However, ultra-thin PCBs can go as low as 0.1mm (.0039″) for certain specialty applications.
  7. What’s the thickest PCB available?
    The largest standard thickness is typically 3.2mm (.125″). But if needed, PCBs can be custom made to even larger sizes.
  8. How does the thickness of a PCB affect its performance?
    A thicker PCB is generally more rigid and can handle more weight, but it also weighs more, which can be a concern in portable devices. The thickness of the PCB can also affect the thermal conductivity and the signal performance in high-frequency applications.
  9. Are there standards PCB thickness?
    The IPC, or Association Connecting Electronics Industries, sets the standards for PCBs including thickness. The standard thickness of 1.6mm(.063″) is derived from these standards.
  10. Does the thickness of a PCB affect its cost?
    Yes, it can. Thicker PCBs require more materials to produce, thus increasing their cost. Similarly, extremely thin PCBs may require more precise manufacturing techniques, which could also increase the cost.
