    What Is Copper Substrate PCB?

    Copper substrate PCBs are the priciest metal substrate PCBs available on the market. Compared to aluminum substrate PCB and iron substrate PCB, its heat conductivity is greater.

    It is excellent for thermal transfer and architectural decorating sectors in high-frequency circuits and places. The copper substrate PCB offers substantial temperature fluctuations and precise communication equipment.

    You may find copper substrates boards with immersion gold, silver, tin, or anti-oxidation treatments on copper. The copper substrate’s circuit layer must handle a significant amount of current.

    So manufacturers use heavier copper foil, with a thickness ranging from 35μm to 280μm in most cases. Al2O3 and silicon powder are the primary thermal conducting components in the copper substrate’s thermal insulation layer.

    Ethyl resin-filled polymers are used to make the composition, which has a low heat resistance (0.15) and great viscoelastic capabilities. It also has great durability to thermal aging and can handle thermal and mechanical stress.

    It is necessary to utilize a copper plate. However, a copper plate may be used as the holding part of the copper substrate with high heat conductivity.

    Copper Substrate PCB

    What Are The Types Of Copper Substrate PCB?

    Manufacturers use a variety of copper substrate PCBs. Copper substrates come in many shapes and sizes, each with its own set of potential uses. The following are the varieties of copper substrate PCB-

    Immersion Gold copper substrates

    As a surface treatment for PCB and packaging applications, Immersion Gold utilizes gold plated precisely on copper. Copper substrate does not co-deposit alongside gold, as was discovered by looking at the gold plating bath’s deposition response.

    An autocatalytic process primarily drives the deposition. Also explored was how copper surface finish and conformal coating duration affected the deposit and soldering properties.

    When the layer thickness is within the 30 to 80 nm range, solder spread-ability is not adversely affected by copper surface roughness. The neutral pH, auto-catalytic type thick electroless gold plating solution deposited on top of the flash gold showed high wire bonding capabilities.

    To succeed, some of the characteristics must be met for the Direct Immersion Gold finish.

    • Minimum copper surface corrosion during deposition
    • Excellent gold Plating layer coverage
    • Copper does not mix with gold.

    Immersion Gold Copper Substrates PCB

    Immersion Gold Copper Substrates PCB

    Immersion Silver copper substrates

    Immersion silver is more affordable than immersion gold. Immersion silver is a viable option if your PCB has connection requirements and you want to save costs. Moreover, immersion silver provides excellent flatness and contact.

    It is common to cover printed circuit boards’ metal pads and through-holes with a tin-resistant and solderable coating. An immersion plating procedure is preferred, followed by a tarnish inhibitor treatment and bright etching of the pads or through-holes used.

    The tarnish-preventer can be added to the immersion plating bath, or it can be used separately. The metal plating is often silver or bismuth, with copper pads and through-holes.

    Immersion Tin copper substrates

    Tin plating for printed circuit boards (PCBs) is known as immersion tin, and it is a distinct technique from hot air solder leveling (HASL). The PCB is made of copper and a dielectric layer.

    OSP copper substrates

    The anti-oxidation copper substrate PCB comprises a dielectric substrate and a copper substrate. It features an insulating thermal dissipation layer placed between the dielectric material and a copper foil layer.

    An immersion gold area is placed on top of the circuit board’s copper foil layer, for welding electronic components, which are then etched. However, except for the immersion gold section, all upper circuit board surfaces are protected by a material layer. from organic welding

    The utility model’s anti-oxidation PCB prevents oxidation of the copper foil layer. It provides a good welding effect and ensures the electronic properties of electronic component connections on the PCB.

    What Is Copper Balancing In Copper Substrate PCB?

    Copper balancing in copper substrate PCB design may bring further advantages and avoid board warpage. The PCB warpage problem is the change of the PCBs form. It is an unanticipated alteration to the PCB. During the soldering process of a warped PCB. If you solder a circuit board, you may notice that the form of the board changes.

    Each layer of the PCB is uniformly plated with copper in the copper substrate PCB, thanks to copper balancing. This generates a constant conductor density on the plated surface, enhancing data communication and overall circuit efficiency.

    Copper balancing plays a crucial function in the PCB manufacturing process. Due to copper balancing in the PCBs, consistent PCB thickness may be achieved during lamination. It further eliminates the possibility of low-pressure zones, which might lead to fabrication concerns requiring a re-design.

    What Is The Usual Copper Thickness Of Copper Substrate PCB?

    When designing a copper substrate PCB, you must consider the quantity of current that will be carried. This should indicate the maximum thermal energy change that the PCB can withstand.

    Moreover, you should also consider how much structural support your copper substrate PCB can withstand by your selected thickness. Drilled holes and layered connections will also have an impact on this.

    When calculating copper thickness, the kind of thick copper PCB material you choose matters. Thermal stability is an essential property for specific materials. Compared to others that quickly fall to such extremes, this will need less thickness to function.

    The ounce is the most used unit of measurement for the thickness of copper on a PCB. What is the thickness of it, though? It is the thickness obtained when 1 ounce of copper is crushed flat and uniformly distributed across a one-square-foot surface. This is equivalent to 1.37 mils (1.37 thousandths of an inch).

    To figure out how thick 4 oz is, multiply 1 oz thickness by 4. 1.37 mil x 4 = 5.48 mils = 4 oz.

    How Does PCB Thermal Management Work In A Copper Substrate PCB?

    When a current travels through an electrical component, it generates heat. The level of heat generated is influenced by the power, component properties, and circuit layout. Electrical connections, copper tracing, and vias contribute to some heat and power losses in addition to the components.

    Designers should attempt to produce PCBs that work and stay under safe operating temperatures to prevent failures or circuit failures. We will go through some of the most prevalent ways of eliminating excess heat from copper substrate PCBs for improved thermal management.

    Improving Copper Substrate PCB Thermal Management

    Improving  Copper Substrate PCB Thermal Management

    PCB Design Best Practices

    The following are the most critical factors to address throughout the design process.

    • Dimensions and performance data for the components
    • Large-scale heat dissipation systems
    • The PCBs Dimensions
    • Design, material, and component placement on a PCB
    • Ambient temperature in the application’s context
    • Effective cooling techniques such as fans and heat sinks.

    It is a good idea to keep an eye on the temperature of components and systems while considering the working conditions. Factors to keep in mind include the semiconductor’s package qualities, heat dissipation properties, and more.

    In most cases, you may find this data in the spreadsheet provided by the PCB maker. There are various ways to cool down overheating circuit boards, including heat pipes, fans, or even layers of thick copper. PCBs with low heat dissipation can be cooled using natural convection.

    Reduce the Thermal Resistivity

    Heat moves through a material significantly more quickly if it has a low thermal resistance. Because of this, resistance is proportional to the length, and cross-sectional area and conductivity are inversely correlated in a thermal pathway.

    Thermal resistance

    θ = t/A × K


    t is the material thickness

    K is the thermal conductivity factor

    A is the cross-sectional area

    Designers often cut down on thermal resistance by:

    • Minimizing the heat path using a thin PCB
    • Incorporating thermal vias to facilitate vertical heat transfer
    • Horizontal heat conduction using copper foil and thick rails

    Make a List of Potentially More Heat-Dispersing Elements

    Itit is vital to know which parts create the most heat to remove the most heat. A designer should use the manufacturer’s datasheet to determine the device’s thermal rating. Typically, manufacturers will include instructions on reducing the amount of heat in the appliance.

    Aspects to Consider Include: Component Positioning, and Orientation

    You should use areas with the greatest heat dissipation for the most power-consuming components. Avoid PCB corners and edges in design unless a heat sink is present. To guarantee proper heat dissipation and appropriate airflow, components should be positioned in the center of the device.

    Though maintaining a uniform temperature distribution may be challenging, avoiding grouping together high-power components. To prevent hot spots, distribute them evenly.

    Another recommended approach is positioning vulnerable components such as tiny ICs, transistors, and capacitors in low-temperature locations. Thermal management can be improved by placing ICs horizontally or vertically long in convection-cooled circuits.

    What Is The Difference Between Copper Substrate PCB And Aluminum Substrate PCB?

    Although copper and aluminum substrate PCBs have comparable qualities and functions, there are some differences. Listed below are some crucial distinctions between aluminum and copper substrate PCBs.

    1. Price

    The cost of the two metal substrates is one of the essential factors in PCB design. While metal prices fluctuate, copper is usually more costly than aluminum due to its limited supply.

    2. Thermal Conductivity

    Due to its ‘Thermal Conductivity’, aluminum outperforms copper when it comes to heat dissipation. Copper boards are superior when high temperatures or high power levels are needed. In other words, copper is good for heat dissipation, whereas aluminum is suitable for other purposes.

    3. Conductivity

    Copper has a distinct edge over aluminum in terms of electrical conductivity and is the greatest choice when it comes to PCB design.  In other words, copper is perfect for situations requiring high electrical conductivity.

    3. Electrical Resistance

    Resistance is critical in PCB design since it affects the component’s overall operation and stability. Being denser than aluminum, copper has less resistance and is thus preferable for smaller circuits and quicker power transmission.

    4. Weight

    Because copper has a more significant density per unit area, it weighs more than aluminum PCB of the same design.

    Aluminum is the recommended material for applications requiring low-weight construction. Copper is often utilized in situations where weight is not a factor.

    What Is The Process Of Copper Plating In Copper Substrate PCB?

    Copper electroplating occurs following chemical plating on the PCB hole edges. It is a cathode with carbon on the PCB panels and the hole walls. The copper surface of the PCB panel is washed, cleansed, and stimulated in several bathtubs before being electroplated.

    The PCB panels’ holes are electroplated synchronously. These holes link the exterior layer parts to the inner layer elements.

    This copper electroplating results in better soldering and stronger solder junctions. This is only feasible with consistent plating over the panel.

    Copper plating is computer-controlled for precision and timing. Keep the panels in the bath for the specified period for best results.

    The hole walls must be coated to 25 microns for optimal conductivity. 30 micron plated surface tracks are also required. With the use of 17.5-micron copper foil, the final thickness may exceed 40 microns.
