Some of the areas of application with such current demands include:

  • Use in military equipment such as for systems for weapons control and radar management
  • Charging systems for high voltage batteries
  • Power supply and distribution equipment

What Qualities does the 10 Oz Copper PCB have?

You find the 10 oz copper CB with the following qualities:

· Ability to Conduct Large Currents

The 10 oz copper PCB can carry large current amounts without impairing performance.

You find that the current carrying capacity is due to the increased thickness of this board type.

A thick copper layer increases the cross-sectional area of the current path.

· Thermal Strain Fortitude

The 10 oz copper PCB can endure thermal strains resulting from the large current constructed.

The thermal power dissipated in the form of heat energy is directly related to the amount of current conducted.

· Good Strength Mechanically

Mechanical strength offers the board the required rigidity to support assembled parts to it such as electronic components.

A 10 oz copper PCB exhibits this strength via the connecting points and plated through-holes.

· Reliable Use

The 10 oz copper can be used in environments where boards with lower value thickness cannot be used.

Environments with high temperatures for example can pose a problem to standard thickness copper PCBs.

The 10 oz copper board can reliably function due to its superior thermal management property.

· Miniaturization

A 10 oz copper PCB is normally configured in a multilayer structure.

Using a multilayer configuration allows the 10 oz copper PCB to be fit into small devices.

The devices made are still able to exhibit high performance.

· Gerenciamento termal

10 oz copper PCB can effectively conduct heat away from the PCB via a heat sink.

The dissipated heat in the board is conducted via heat vias to the dissipador de calor.

The heat sink is attached to the bottom surface where it externally removes the thermal energy.

PCB de 10 onças

10 Oz PC

How is Temperature Rise Controlled on a 10 0z copper PCB?

For the 10 oz copper PCB, higher amounts of heat loss are experienced.

The increased thickness allows more current to be conducted resulting in more heat dissipation.

You also find that the trace width influences the amount of heat released.

The 10 oz copper PCB uses heat sinks to conduct heat away from the board.

A heat sink collects the dissipated heat energy from the board via conduction.

It then releases this heat externally via convection.

A heat sink is usually made of a material with good thermal conductivity such as copper or aluminium.

It is then attached to the bottom of the 10 oz copper PCB construction.

The attachment used should also be thermally conductive and preferably with matching CTE.

With construction of many layers, heat has to be collected from each and transferred to the heat sink.

Plated holes are used to conduct thermal energy through the layers.

Plating is done using a material with good thermal transfer property.

Heat sinks can be attached during the assembly process or built into the 10 oz copper PCB.

The latter option is less costly and with a superior outcome.

The thick copper used in the fabrication of the 10 oz copper PCB is also used for the heat sink.

When fabricating 10 oz copper PCBs with heat sinks, they are electroplated to the bottom surface.

This way, a continuous path is provided for the heat vias.

Furthermore, the vias provide a path of least resistance for the thermal energy.

How is Manual Routing Carried out in 10 Oz Copper Board PCB Assembly?

Routing is a procedure succeeding placement where wires are added for proper component connectivity.

This process can either be performed manually or automatically or both processes used.

When routing manually, you first start with the most sophisticated and difficult connections.

Approaching the routing process from the difficulty angle ensures a reduction of errors at latter routing efforts.

Following the connection of the complex routes, the next step is to work on the nets with tight fittings.

External routing for components using high currents follows with internal components pulling large voltage values completing the process.

What Material Characteristics are Required for the Inner Layer Core on 10 Oz Copper PCBs?

The following characteristics are pivotal for materials used for the inner layer core of the 10 oz copper board:

  • A high glass transition temperature is important for the inner layer core.

A high value allows the core to withstand large thermal changes in the 10 oz copper board.

Otherwise, the inner layer would melt resulting in a weak material bond.

  • Material used for inner layer core should have standard tensile strength.

Tensile strength gives the inner layer core ability to withstand stretching forces.

Such materials should not easily break or fold under strains.

  • Another characteristic is the material’s shear strength. Shear strength is exhibited to tolerance against shear force.

When a shear force is applied, material succumbs to it by tearing.

The direction of tear is usually parallel to the application of the force.

  • The materials used in the inner layer core should have matching or close CTEs.

The coefficient of thermal expansion illustrates the response to temperature changes for materials.

Materials with non-matching CTEs will respond differently to temperature changes.

  • It is important to identify the dielectric constant of materials used in the inner layer core.

A constante dielétrica is especially useful when the 10 oz copper PCB is intended for use in a high-frequency environment.

  • A low loss tangent is crucial to the inner layer core to prevent electromagnetic interference.

Loss tangent is actuated by wave energy absorption which is influenced by frequency levels.

  • The inner layer core materials should not be able to easily absorb moisture content. Moisture content is prevalent in wet conditions and humid areas.

Water molecules affect the dielectric properties of the material and resistance to tracking effect.

  • The material should have a high dielectric breakdown voltage.

Also, the materials selected for the inner layer are not desired for their electrical properties.

Their ability to conducted electric charge will affect the board connection even resulting in shorts.

How is the Copper Trace made on the 10 Oz Copper PCB?

When making copper traces on a 10 oz copper PCB, the length, width and spacing of the traces are important parameters.

Knowing the amount of current a trace is supposed to handle can help in providing just the right measurements.

Two approaches can be used to lay the copper trace on a 10 oz copper PCB.

You find the trace can either be etched or plated.

· Gravura

Gravura a copper trace involves the removal of the undesired copper surface that leaves the copper in the desired trace pattern.

In this process, a resist is used to cover the copper surface with the desired trace pattern.

An aqueous solution is then sprayed over the copper surface.

The exposed copper reacts with the solution but the surface covered with resist is left unaffected.

The resist is removed to expose the copper in the desired trace pattern.

· Plating

Plating occurs when a metallic compound is deposited over another.

In plating a copper trace, the desired trace pattern is developed by depositing copper over the board surface.

The process is carried out such that the resulting pattern matches the design.

What are Some of the Considerations when Designing a 10 Oz Copper PCB?

Designing a 10 oz copper PCB requires attention to the nature of its application and its current demands.

How is the Glass Transition Temperature important in a 10 Oz Copper PCB?

When making a multi-layered 10 oz copper PCB, laminates are used to hold together the layers.

Laminates are usually composed of fiberglass material reinforced with epoxy or resin.

The glass transition temperature is an important parameter for these laminates.

The glass transition temperature is the temperature at which a material with glass properties tends to change form into a viscous state.

For laminates in 10 oz copper, they have to have a high glass transition temperature.

10 oz copper PCB carries large currents.

It follows that the amount of heat energy dissipated is equally large.

Laminates with low glass transition temperature will succumb to the thermal dissipation and change from leading to a weak structure.

Como você pode testar um PCB de cobre de 10 onças?

Testing a 10 oz copper PCB can be effectively carried out by the in-circuit test.

In this test process, an assembled PCB is assessed by an electrically controlled probe.

This test type searches for shorts and opens in circuits, as well as capacitance and resistance.

In this test, multiple pins on a fiberglass base are used to conduct the test.

They are arranged such that their pins touch several points of test on a PCB.

Also, the points are located on circuit nodes on the 10 oz copper PCB.

You find that exerting a small force on the PCB pressing it against the pins creates contact.

Every pin interacts with a point on the board at the same time.

The pins are individually connected to measuring devices, as such; recordings for every test point are made.

The adherence of the pin bed and the 10 oz copper PCB is established by mechanical force or vacuum placement.

The latter process provides more accurate readings.
