What is the application of 4oz copper pcb?
◎First of all, the modern PCB industry uses 4 oz. copper thickness in electronic devices that require high technology. In addition, you can apply 4 oz PCBs in soldering equipment.
◎Power converters are configured using 4 oz PCBs. In addition, you can also find this PCB useful in space systems and high-tech radar systems.
◎In addition, the 4oz copper PCB can be used in automotive and solar panel systems. It can also serve for electrical or general power systems.
◎Control panels are available for different industries. 4oz PCBs play an important role in industrial panel manufacturing. You will also find 4oz PCBs in vending machines, automotive instrument panels, amplifier systems, and lighting systems.
Surface finish of Venture 4oz pcb
The surface finish is related to the coating of the material, which is usually located between the components of the circuit board. Applying this surface finish is necessary to ensure that the soldering of the circuit board components is tight enough.
Another reason why surface finish is important is that it protects the copper circuitry of the board. In addition, it protects the board from oxidation.
For 4 ounce PCBs, HASL – Hot Air Solder Leveling is the primary surface finish. This finish includes a double layer of metal coating and nickel. In addition, it is repairable and cost effective.
In addition to HASL, ENIG surface impregnation is also useful. ENIG stands for Electro-Nickel Impregnated Gold. This gold layer helps to protect the nickel layer.In addition, you can use lead-free HASL. All of these surface treatments help protect your 4 oz. PCB from any damage.
The survivability of a 4 oz CopperPCB is very important. It must continue to work under adverse conditions.
Venture Electronics choose different types of materials because the manufacturing affects its survivability.We choose the dielectric material FR-4 or high-temperature polyimide.FR-4 works at 130 degrees Celsius, while high-temperature polyimide works at 250degrees Celsius.Extreme environmental conditions can affect the material of a 4-ounce copper PCB.
The printed circuit board industry has developed a number of methods,it allows you to check the integrity of a 4 oz. copper PCB.You can also use a test called TCT (Thermal Cycling Test).
You can use this test to test the resistance of a circuit by cycling the temperature from 25 degrees Celsius to 260 degrees Celsius.
Venture 4 oz Copper PCB design can render some benefits such as:
- Capability to survive frequent exposure to excessive current
- High tolerance capacity that makes it compatible with applications in rough situations
- Compact product size due to several copper weights on the same layer of circuitry
- Onboard high-power-density planar transformers
Venture expertise is a design supplier at a reasonable cost, heavy copper PCB that is of proven designs. Our engineering team can work with you to review your design to make sure that they can be supplied with the highest quality at the best overall cost. Venture ensures maximum control over quality and the ability to design and produce custom to customers’ specifications.
- Heavy copper-plated vias pass the elevated current through the PCB and assist in transferring the heat to an outer heat sink
- It also elevated temperatures and recurring thermal cycling
- The amount of current a copper circuit can safely carry depends on how much heat rise
Heavy copper PCBs are utilized for various purposes such as in planar transformers, heat dissipation, planar transformers, power converters, high power distribution and more. There is an increased request for heavy copper-clad boards in a computer, automotive, military, and industrial controls. Heavy copper printed circuit boards are also utilized in:
- Power Distribution
- Automotive Industry
- Welding Equipment
- Solar Panel
