2 Oz Copper PCB - PCB Manufacturing & Assembly – NextPCB

Posted:05:54 PM November 30, 2022 writer: NextPCB

1903 saw the creation of the first PCB Design patent. Using non-plated through-holes, single- and double-sided boards were still used in 1946. Double-sided plate through-holes were also invented in 1947, and in 1960 multilayer processes began. The baseboard is the physical support and wiring for the mechanical, electrical, and electronic components. They can be of various types based on copper weight, the number of layers, substrate materials, designs and structure, and conductor pattern.

The 2 oz copper PCB is the type that is based on copper composition in PCB. The more the thickness of the copper, the more the reliability in designs enhances. 2 oz is a reliable PCB type with good thermal control, current, etc. It comprises broad application areas like drug delivery, automotive industries, etc. 

This article summarizes the 2 Oz Copper PCB including its components and the fabrication process. It also compares 1 oz and 2 oz copper PCB.

What is 2 Oz copper PCB?

A printed circuit board known as a "2 oz copper PCB" has a copper weight per square foot of two ounces. Two ounces of copper are flattened to create a square surface one foot in size. This board type has a final thickness of around 2.8 mils or 70 micrometers. It is applicable to high-power boards.

Fabrication Process

Fabrication of 2 oz copper PCB includes several processes. The steps are listed below:

  • The computer program provides instructions to the machines to prepare a design module.
  • The photo plotter helps to prepare layers of the material in a graph of the required designs.
  • Similarly, based on application requirements, the inner layer prepares.
  • Fabricating the layers involves a lamination process for binding them together. 
  • After that, holes at the designated points are drilled to guide them further, such as placing the components.
  • Then, holes are plated to provide conductivity in the internal layer.
  • Then, to place the components, you need to analyze the board with the outer layer.
  • Using evaluation and analysis, you can diagnose the board.
  • To coat the copper traces, you can mask them with solder
  • Finally, you can print the circuit board
  • Later, tested with a finished 2 oz copper board with packaging.

2 oz copper PCB thickness

The minimum required thickness conditions for the 2 oz PCB is 70um of 2.8 mils thick. The thickness influences the functionality and performance of the board. The spacing helps during the soldering while arranging and placing the components. The spacing helps in assembling the devices.

Components used in 2 Oz copper PCB

The 2 oz PCB includes several passive and active components. The transistors, transformers, IC chips, diodes, etc., are some active components, whereas resistors, inductors, capacitors, etc., are the passive components common in this 2 Oz PCB.

Transistors

Being an active device, it too weighs higher importance in PCB design. Also, offers to switch and control the circuit. Comprising its many advantages in any circuit, sometimes it shows low blocking capacity in the reverse direction. But comparatively, it properly provides the flow of current between the emitter and collector compared to the switch.  

IC chips

IC chip comprises the semiconductor layer using copper or other materials. Besides storing memory in computers, mobile phones, etc., for amplification, oscillation purposes, etc.   

Diodes

In one of the active components, diodes take a higher position in importance. Also, it is much applicable in an electronic environment. It includes converting to Dc from AC, isolating signals, etc.

Capacitors

It is the core component required for PCB design. Besides, it helps to discharge and save energy in any circuit design with PCB. It also maintains the voltage in the provided layer.

1 Oz vs. 2 Oz copper PCB

1 Oz and 2 Oz Copper PCB

  • Compared to 1 oz copper PCB, 2 Oz copper has high power bands, with higher compatibility of adapter and charger.
  • Anyone can deliver a large ampere of current with 2 oz PCB compared with 1 Oz.
  • On speaking with efficacy, 2 oz weighs much to 1 oz. 
  • 2 oz PCB owes better thermal control to 1 oz copper PCB.
  • In comparison to 1 Oz copper PCB, the 2 oz offers applications in many broad areas where there is a requirement for high power bands.
  • For the case of handmade prototypes, 2oz is better with the convenience of peeling the area, and for the case of soldering, 1 oz copper provides more easiness. 
  • With different thicknesses for each, 2 oz has two ounces of copper, whereas 1 has one ounce of copper utilizing a weight of copper by flattening it.
  • Compared to the 1 Oz PCB, 2 oz PCB requires more operational and maintenance costs. 

Conclusion

Anyone can choose the 2 oz copper since it comprises almost all application areas. The 2 oz PCB board provides excellent power quality with current enhancement. The customers can choose the 2 oz copper for much flexibility in any design.
