1. What You Need to Know About Copper Weight

Before discussing copper weight, it is essential to learn a thing or two about this material. Copper is a chemical element that belongs to the category of metal. In the construction of PCBs, copper is used as an alloy.

That is what enables it to be a great conductor, and it is why it is used in devices manufactured across various industries. It is also the reason why it is one of the major components of any printed circuit board.

It is important to note, however, that copper can’t be a conductor on its own. If you want to see, its conductivity PCB manufacturers ensure that the copper they implemented carries a charge.

2. PCB Copper Thickness–How to Calculate Copper Weight

If you want to calculate copper weight, you need to have all the necessary information. Start with the copper form, a tube, sheet, bar, or another type if the manufacturer gets creative.

The next thing you need is to consider the copper grade. It is essential to check whether you are using pure copper or an alloy combined with other materials, such as nickel. Depending on that, you can determine the grade precisely. In most cases, PCB manufacturers use copper that has a C110 class.

Flat bars and sheets are the most common forms of copper used in printed circuit board manufacturing. However, it is not that unusual that the designer melts down other copper shapes to use them for plating.

When it comes to PCB copper thickness, you should know that it is calculated in ounces. The measurement represents a copper ounce’s thickness when you roll it out on a single square foot. If you notice the information specifying that you are dealing with a one-ounce copper, its thickness is 1.37 mils.

Even if it sounds confusing, the good news is that you can leave everything to the pros. The only thing you should know is how to pick the right thickness for your desired application, and your preferred manufacturer will turn your desires into reality.

3. 1 Oz Copper Thickness – the Most Common Weight Used for PCBs

Although it may seem a bit unusual, the thickness of the copper used in PCBs is measured in ounces. Now that we learned the details, we will assess the different weights used in printed circuit boards.

If you are not a PCB expert, you might want to know which size clients most frequently order from the manufacturers. The statistics will tell you that it is 1 Oz copper that is usually a component of a printed circuit board.

The majority of the companies consider this to be the standard PCB copper thickness. Unless the buyer states otherwise, they will use this thickness, and there is a good reason for that. A 1 Oz copper can carry more than enough current for most applications. As such, they are very versatile, and you can use them in both rigid and flexible printed circuit boards.

The experts consider 1 Oz copper thickness to be the optimal deal in terms of price, too. If you aren’t making a product that requires an excessive amount of current, the chances are this size can do the job and meet your expectations. You will get a reliable and durable component that can secure a consistent performance of your board.

At the same time, you won’t overspend on thick copper without any real need to do so. It is about the added cost of the more massive copper and its time to complete the order. The manufacturers might need a bit of time as it is more challenging to apply heavier copper.

If you need thickness bigger than one ounce, you should always choose a reliable company with experienced staff. They will ensure to provide a fantastic product that will be in line with all your requests.


4. PCB Copper Thickness–What Are Other Copper Weights Available?

Apart from the standard PCB copper thickness, you also have other different weights available. These include:

  • 0.5 Oz copper – its width is estimated at a bit less than 0.7 mils. It can be an excellent choice for small products and applications that do not require high conductivity. However, since those are rare, this size is also an exceptional choice among the customers. Its thinness makes it the riskiest for overheating when compared to other weights.
  • 2 Oz copper – the thickness is around 2.75 miles in this case. It is a rather generous copper weight, which is why some are wondering whether it is necessary. The truth is that it depends on your application. You can find many products where this is the minimum needed thickness for everything to work flawlessly.
  • 3 and 4 Oz copper – if you want to make a bulletproof PCB that will have the highest productivity possible, large weights can be the right choice for you. They are incredibly reliable, but you want to consider whether it is a necessary investment.

While designing your printed circuit board, you need to consider the desired thickness. The thing to pay special attention to is the space between copper features. This space will vary depending on the thickness you select, but it is essential to leave a gap that will be large enough for everything to work effortlessly.
