Simple Methods for Measuring FR-4 Foil Thickness in PCB Manufacturing
By:Admin
Thankfully, there are a few methods that engineers and technicians can use to measure the thickness of the foil on FR-4. Here are some of the most popular options:
1. Micrometer: A micrometer is a precision tool used to measure small distances or thicknesses. When measuring the foil thickness on FR-4, a micrometer with a range of 0-1 inch and a resolution of 0.0001 inch can be used to achieve accurate results.
2. Cross-Sectioning: Cross-sectioning involves cutting a small slice of the PCB and examining it under a microscope to determine the thickness of the copper layer. Although this technique is more time-consuming and invasive than others, it is also one of the most accurate options available.
3. X-ray Fluorescence: X-ray fluorescence (XRF) is a non-destructive method used to analyze the elemental composition of a material. This technique can be used to determine the thickness of copper foil on FR-4 by analyzing the XRF signals from the material. However, XRF equipment can be expensive and may not be accessible to everyone.
In addition to these methods, it is important to note that different brands of FR-4 may have slightly different foil thicknesses. Therefore, it is always a good idea to consult the manufacturer's specifications or contact them directly to get accurate information.
Overall, while determining the foil thickness on FR-4 may require some effort, the results are well worth it. Knowing this parameter can help ensure the proper functionality and reliability of PCBs in various applications.

Inflatable vs Epoxy: Which Type of SUP Board Suits You Best?
and Inflatable SUP.Stand Up Paddleboarding or SUP has become one of the most popular water sports in recent years. Whether you’re looking to explore your local waterways, catch waves, or get a full-body workout, owning a paddleboard allows you the freedom to do so. However, choosing the right board can be a daunting task, especially when it comes to deciding between an inflatable SUP or an epoxy board. In this blog, we’ll explore the pros and cons of each and help you make a decision that’s right for you.Inflatable SUPAn inflatable SUP is a paddleboard that can be inflated using a pump to a rigid and stable shape. They are made from PVC material and come in various sizes and shapes. Here are some key points to consider if you’re thinking about purchasing an inflatable SUP:Portability: One of the biggest advantages of an inflatable SUP is its portability. It can easily be deflated and stored in a compact bag, making it ideal for travel, camping, or even hiking.Durability: Contrary to popular belief, inflatable SUPs are highly durable and resistant to punctures and scratches. They are also easy to repair with a simple patch kit.Versatility: Inflatable SUPs are suitable for a wide range of activities such as recreational paddling, yoga, fishing, and even racing.Price: Inflatable SUPs are generally more affordable than epoxy boards and offer great value for those on a budget.Thickness: In terms of thickness, inflatable SUPs tend to be thicker than epoxy boards, which adds to their stability and buoyancy.Epoxy BoardEpoxy boards, on the other hand, are made from a foam core surfboard wrapped with layers of fiberglass and epoxy resin. They are ideal for surfing, racing, and touring. Here are some key points to consider if you’re thinking about purchasing an epoxy board:Performance: Epoxy boards are known for their excellent performance in the water. They are faster, more responsive, and more maneuverable than inflatable SUPs, making them perfect for those looking to catch waves or compete in races.Stability: While inflatable SUPs tend to be thicker and more stable, epoxy boards can provide just as much stability, especially with the right width and volume.Durability: Epoxy boards require more maintenance than inflatable SUPs and should be protected from the sun and scratches. They are also more susceptible to dings and cracks that need to be repaired.Price: Epoxy boards tend to be more expensive than inflatable SUPs, which can be a barrier for those on a budget.Different Thickness Epoxy Board: Unlike inflatable SUPs, epoxy boards come in different thicknesses that can significantly impact their performance and stability. Thicker boards are more stable but slower, while thinner boards are faster but less stable.Which one should you choose?Ultimately, choosing between an inflatable SUP and an epoxy board comes down to personal preference and what activities you plan to do. If you’re looking for a board that’s highly portable, durable, and versatile, an inflatable SUP is the way to go. But if you’re looking for a high-performance board for surfing, racing, or touring, an epoxy board is the better option.As with any purchase, it’s important to do your research and invest in a board that meets your needs and budget. Both inflatable SUPs and epoxy boards have their pros and cons, so it’s up to you to decide which one is right for you. Happy paddling!
