Application Of Heavy Copper PCB

When designing a Heavy Copper PCB, one of the first factors to consider is the material used for the substrate. There are many types of materials to choose from, including ordinary FR-4, which has a standard operating temperature of 130degC, and more advanced materials that have high glass transition temperatures. It is critical that the copper and substrate material has a similar Tg or glass transition temperature (Tg). High current can cause cracks and layers to separate, so selecting the right material for your Heavy Copper PCB is essential.

High thermal endurance

A heavy copper PCB can be an excellent choice for electronic applications. This material integrates several copper weights onto the circuitry layer, allowing it to carry more current and dissipate heat to an external heat sink. Additionally, a heavy copper board is a smaller and more compact than a standard one. As a result, it offers reduced layer counts, a smaller footprint, and low impedance power distribution. In addition, this material is cost-effective, as it reduces the amount of copper that needs to be used in a circuit board.

The thickness of heavy copper PCB varies between manufacturers, so it is essential to choose a supplier that offers the appropriate thickness. A PCB with too thin a copper layer will not be able to carry the heavy current that is required, causing the product to fail.

Easy fabrication

Heavy copper PCBs are a type of circuit that requires the high-quality use of finished copper and laminated deposition. These circuits are fabricated in a variety of ways and require different manufacturing tolerances than standard PCBs. The design of heavy copper PCBs should be reviewed with a fabricator early in the design process to ensure that the final product will meet all specifications.

In this fabrication method, heavy copper PCBs are manufactured with uniform thicknesses and copper PADs of uniform size and shape. These copper PADs can be round, square, oval, or diamond-shaped. The thick copper plates are arranged equidistant along the long edge of the board.


Heavy copper printed circuit boards are the latest trend in the PCB industry. These circuit boards are more expensive to make but are in high demand. These boards are made of more than three ounces of copper per square foot. Typically, heavy copper PCBs are four ounces thick per square foot and weigh up to twenty ounces per square foot of copper. In extreme cases, PCBs may weigh over 200 ounces per square foot.

Heavy copper PCBs are manufactured in the same way as light copper circuit boards, but require more complicated etching and plating techniques. Traditionally, heavy copper circuit boards were formed by etching a layer of thick copper-clad laminated board material. However, this method resulted in uneven trace sidewalls and unacceptable undercutting. However, recent advances in plating technology have made it possible to combine etching with plating, resulting in flat sidewalls and minimal undercutting.

What To Look For In Biodegradable Sterilization Wraps

Medical organizations are focused on enhancing the safety of their staff, but more importantly on ensuring the conservation of the environment. The area where a significant amount of pollution is attributed to the sterilization wraps. Sterile surgical tools are a major imperative in the surgical field of medicine. It is a global recommendation that all surgical equipment be sterilized and medical institutions have and manufacturers of medical and surgical equipment are packaging such tools to enhance their sterility.

However, sterilization wraps are required to provide basic protection against contamination in the process of handling them by offering a cover against microbial infection. While there are many ways of maintaining sterility of surgical tools, the most popular method adopted has been sterilization of wraps. The most interesting fact about these materials is that they are soft, recyclable, cheap, and can easily drape. The only downside is that a majority of these wraps are woven, which means they do not have the capacity to prevent microbial penetration. To help increase protection, manufacturers are now embracing double sequential wrapping.

What are the Features of a Good Surgical Sterilization Wraps?

Here are the key features of an ideal sterilization wraps that you can find on the market:
• They should be non-toxic
• Have no odor
• They are resistant to puncturing
• They should be transparent to allow for easy verification of the contents in the pack
• Resistant to tears
• They should be flexible to allow for accommodation of surgical equipment of all sizes and shapes
• Drapeability: this is the compliance of the wrap with the contours of the equipment
• Penetrability: it should allow gases or plasmas to easily penetrate the wrapping surface in order to sterilize the contents.

Characteristics of an Ideal Wrap

There are many qualities you should look for in a sterilization wrap as outlined above, but the core quality is the ability to prevent microbial penetration and ability to let sterilization gases to penetrate the pack. Some of the commonly used sterilization agents include hydrogen peroxide gas plasma, steam, and ethylene oxide. The inability to allow for penetration of sterilizing agent and subsequent inability to maintain sterility of the surgical equipment can lead to possibilities of serious site infections. Therefore, those looking to buy a Biodegradable Sterilization Wrap should be certain that the product conforms to all of the above characteristics.


The modern Biodegradable Sterilization Wraps for providing protection to surgical equipment are superior compared to the conventional wraps. As a professional, it is important to evaluate the products before making a purchase decision. Such an evaluation should be done based on the guidelines outlined in this article.

Benefits Of Hard Plastic Sheets

The use of Hard Plastic Sheets is gaining momentum these days, especially on Do It Yourself (DIY) projects. Is it now a common phenomenon both in residential and commercial settings. These Plastic Sheets are primarily used, as they are much beneficial.

Now, what are the benefits of Plastic Sheets?

It has been discovered that glass is a dense material prone to breakages from little annoyances. Besides, when small ruptures occur, they need complete replacement. With the plastic sheets, this is never the case. Here are some of its benefits.

They are:

-More durable compared to glass
-Shatter resistant
-Come in a variety of finishes, therefore, can fit every project
depending on an individual preference
-Easy to cut to required sizes
-Easy to clean
-Cheap when compared to glass
-Unique as you may like whereas glass is uniform
-Easier to move around
-Lighter when compared to glass
-Versatile in its possible uses
