What is the thickness of 1 oz of copper on a PCB?
1.37 mils
The most common unit of measure for the copper thickness on a printed circuit board is ounces (oz). But how thick is that? It’s the resulting thickness when 1 oz of copper is pressed flat and spread evenly over a one square foot area. This equals 1.37 mils (1.37 thousandths of an inch).
How do you choose copper thickness?
There are two key elements to consider when determining optimal PCB copper thickness. The first is the current capacity of the barrel for acceptable heat rise. The second is the mechanical strength determined by the copper thickness, hole-size and whether or not there are any support vias.
How thick is copper on a PCB?
The typical PCB copper thickness on a copper-clad laminate will be 0.5 oz/sq ft or 1.0 oz/sq ft, although they can generally procure heavier copper as needed, or they can plate up exposed copper to a desired thickness if needed.

How do you calculate PCB thickness?
When determining the PCB thickness, there a number of design and manufacturing factors to consider, as listed below.
- Design Factors that Impact PCB Thickness. Copper thickness.
- Manufacturing Factors that Impact PCB Thickness.
- Factor 1: CM’s equipment capabilities.
- Factor 2: Extended turnaround time.
- Factor 3: Additional cost.
Does PCB thickness matter?
As electronic devices shrink in size, so too has the PCBs shrank. That requires the boards to be lightweight and thin to fit inside the device. Because of that, the thickness of a PCB is essential to the board.
What is standard PCB thickness?

Can I melt down pennies and sell the copper?
It is not illegal to melt, destroy, or modify any U.S. coins in the United States.
Should you save copper pennies?
So, your best option is to keep those copper pennies until they get rid of the penny, and sell them then. It will be a nice way to make so money! It might seem not worth it now, but in 2026 you will smile upon the day you started to save copper pennies! Thank you for reading, and good luck coin roll hunting!
What has the most copper in it to scrap?
Older appliances have more copper which gives you more scrap and more money. Washers, dryers, refrigerators, and air conditioners make great scrap appliances for their copper coils.
What is considered number one copper?
#1 Copper. #1 copper is the second most profitable type to trade in. To be classified as #1, the copper should be comprised of bus bars, clippings, commutator segments and wire of at least 1/16th of an inch in diameter. It should also be clean in appearance, unalloyed and uncoated.
What is 2 oz copper PCB?
A 2 oz copper PCB is a printed circuit board whose copper weight per square foot amounts to two ounces. To make this circuit board, copper of two-ounce weight is flattened to form an even surface with square dimensions of one foot. The resulting thickness of this board type is about 2.8 mils or 70 micrometers.
Are thicker traces better?
The thicker traces have been optimized for current carrying capacity and are used for peripherals or power-related functions that demand higher power, such as fans, motors, and general power delivery to lower level components.
Is throwing away money illegal?
Is It Illegal to Throw Away Money? In the United States, it is illegal to damage or destroy currency, and while the law may not say directly that it is illegal to throw money away, tossing any U.S. currency in the trash will likely be treated as destroying the money.
Why is melting pennies illegal?
Pennies and nickels contain copper, zinc, and other metals that are of great monetary value. It is because of this that melting down these metals for the sole intention of selling to offshore or local metal scraping industries is illegal.
