In thick copper PCB, printed circuit boards are versatile components used in various industries and electrical devices. For quality control purposes, the thickness of the copper coating lining the hole is measured using the eddy current method. Accurate measurement of copper thickness in coated PCB holes is facilitated with specialized use in conjunction with eddy current instruments. Did you know that copper PCB thickness could be crucial when designing the perfect board for your needs? Copper plays a vital role in PCB conductivity, which is why you need to choose the ideal thickness for your application. See our guide and learn about the different weights available.
Know about copper weight
Belonging to the category of metals, copper is a chemical element. In the construction of PCBs, manufacturers use copper as an alloy. Copper cannot be a conductor on its own. If you want to see its conductivity capabilities, you need to heat it or cool it down to a specific temperature. It is how PCB manufacturers ensure that the copper they implement carries energy.
Calculate copper weight
If you want to calculate the copper weight, you will need to have all the necessary information. Start with a copper shape, which can be a tube, sheet, or bar. The next thing you should consider is the copper grade. It is essential to check whether you use pure copper or an alloy combined with other materials such as nickel. Depending on that, you can determine the degree precisely. The most practical forms of copper used to manufacture printed circuit boards are Flat bars and sheets. You must measure the PCB copper thickness in ounces. The measurement represents the thickness of an ounce of copper when unrolling it into a single square foot.
1-ounce copper thickness – the most common weight
If you are not an expert, you may want to know what size customers typically order from manufacturers. Most companies consider 1 Oz copper the standard amount for PCB copper thickness. They are versatile and can be used on rigid and flexible printed circuit boards. Experts believe a 1-ounce copper thickness is an excellent deal on price. If you are not making a product that requires a high amount of current, that amount is likely to work and meet your expectations.
You will have a safe and durable component that can ensure consistent performance from your board. At the same time, you will not spend much on thick copper if you do not have to. Manufacturers may need more time because it is challenging to apply heavier copper. If you need thicknesses more significant than 30 grams, you should always choose a reliable company with experienced employees. These will ensure you have a fantastic product that meets all your requirements.
As electronic devices get smaller and smaller, the conductive paths must be closer together on the printed circuit boards. It is why most PCBs today have multiple layers. For the transfer of electronic signals across all layers, these are connected by plated through holes, also called pathways, electrodeposited with an electrically conductive material such as copper.
