The main features of the 3 oz copper PCB are listed as under:

Features of 3 oz Copper PCB
Almost all types of 3 oz copper PCB are made up of the copper lamination on the board.
In addition to the copper lamination, Tin alloy is also used to make the additional thick copper PCB.
Besides this, many other conductive materials are also integrated with the copper layers to build the circuit integrity in the PCB copper circuit.
Steel wood is also used to build sturdiness in the PCB circuits and make them more stable.
Some components of the thick copper PCB are also made up of carbon steel materials. The Prepreg material is also coated with resin and then dried in the thick copper PCB of thickness 3 oz.
The primary reason for using Prepreg material in 3 oz thick copper PCB is to enable the circuit to withstand the extended temperatures.
Laminates are also made of thin copper sheets, which are then integrated with the Prepreg materials on either side of the PCBA circuit.

Materials are included in 3 oz Copper PCB
The Primary Difference between the 2 oz copper PCB lies in the thickness of the copper material used to construct their layers.
The thickness of the 2 oz thick copper PCB is estimated up to 70 micro-meter or 2.8 mils, whereas the thickness of the 3 oz thick copper PCB is estimated up to 3.0mm.
However, there are many other prominent differences between 2 oz thick copper PCB and 3 oz thick copper PCB.
Some of these differences include thermal conductivity, electrical conductivity, and stability.
3 oz thick copper PCB is regarded as a better conductor for heat and electricity than the 2 oz thick copper PCB.
Moreover, 3 oz PCB circuit layers are considered the Heavy PCB because of the prominent thickness of the copper, whereas the 2 oz copper circuit PCBs are known as simple PCBs.
The number of layers on the adjacent sides of both 2 oz and 3 oz thick circuit PCB is different.
The 3 oz PCB contains more copper layers than those present in the 2 oz copper circuit PCBs.

Difference Between 2 oz and 3 oz Copper PCB
Yes, 3 oz copper PCB is mainly used on the printed circuit board fabrication because it can provide mechanical support to the circuit.
Besides the mechanical support, it also helps the circuit components to connect electrically.

3 oz Copper PCB is defined as a particular type of PCB circuit board with copper layers weighing about 3 oz.
The copper layers are arranged in a particular order to create a PCB weighing only 3 oz. There are also many other types of PCBs with varied weights of copper.
The specified separation of copper around the PCB board is responsible for the particular design of the circuit board.
The minimum thickness of the 3 oz copper boards in the PCB circuits is estimated at up to 3.0mm. In addition to this, the finished copper thickness in such kind of PCB is also 3 OZ.
The solder mask in the 3 oz PCB circuits is white to determine the separation of the copper layers in the circuits.
The particular thickness in the copper PCB is responsible for specifying its thermal conductivity along with the PCB board thickness.
Moreover, the thermal conductivity and the current carrying capacity of the PCBs are also related to the thickness of copper in PCB circuits.
Thus, the increase in the copper thickness increases the thermal conductivity and current conductivity of the PCBs.
3 oz Thick Copper PCB
The thickness of the 3 OZ copper PCB is estimated up to 10 mil or 0.254mm.
This estimated value of the thickness of copper PCB is also given as 105 Micron. The high thickness of the 3 oz copper circuit PCB also gives it a Heavy Copper PCB name.
This heavy copper PCB is then integrated with the other thickness level PCBs to make a multi-layer PCB circuit.
A high-quality solder mask is used to adjust the copper layers over one another for attaining the desired thickness level of the PCB circuit board.
In addition to this, many manufacturers, including SMTFAB, have the service to produce PCB circuit boards with varying thickness levels.
All you need to do is to visit their website and ask about the desired thickness level of the Copper PCB circuit boards. They will provide you the highest quality PCB circuit boards.

The copper layers in PCB circuits are measured in ounces per square foot or called (oz/ ft2).
Besides measuring the thickness of copper in PCB circuits, it is also essential to measure the external factors such as standard temperature or the pressure environment.
For measuring the external factors of the PCB circuit, 215.3 is regarded as the common scale factor.
Another method for determining the thickness of 3 oz copper circuit PCB is the copper thickness conversion method.
In this method, the required PCB layer’s thickness is multiplied by the 1 OZ thickness and 1.37 mils.
In addition to all this, many other substantial factors significantly impact the thickness of the copper in heavy PCBs.
Some of these factors that you need to take into consideration while measuring the thickness are listed as under:
