What are the Different Layers Available in a RO4233 PCB?

RO4233 has several layers built in it.

These layers are the:

 Different layers of PCB

 Different layers of PCB

Mechanical Layer or Mechanical 1

TheRO4233  PCB can have several mechanical layers,, but you need at least one to assemble the board.

It outlines the size of your PCB board.

The fabricator cuts out the RO4233 PCB in the correct size from the stock material.

It can come in rectangular, round-cornered, or other kinds of shapes.

Rarely will you add detail tooling specifications and other mechanical information on the mechanical board.

Keep Out Layer

This layer will highlight the working area of the design.

An example may be drawing back the components 1/2 of an inch from the mechanical layer.

It will identify areas on the board that you should avoid for mechanical or other purposes.

Routing Layer

This is the layer that the components interconnect.

Designers spend a lot of time perfecting this layer.

This layer is present on both the outer [top and bottom layers] and an inner layer of the RO4233  PCB.

Always provide this layer for the fabricator to create the board.

Ground and Power Planes

These are solid copper layers that you will shorted on a fixed potential.

Connect ground planes to the GND and the power planes to one of the onboard voltages.

They are available on the top, bottom, or in the internal part of the board.

These planes provide power and ground on all components.

They can also achieve better performance on specific conditions.

When customizing RO4233 PCB, provide all PCB fabrication files that describe the plane within the design.

Split Planes

It is possible to modify ground and power planes for them to contain several copper sections on different potentials.

Also, they will improve the convenience of the planes.

For instance, a plane can have several voltages that will distribute +5 V and -5 V on different sections of the board.

Silkscreen Layers

It is also known as the overlay.

They will provide the text designators on the components at the top and bottom of the layer.

Provide additional files to the fabricator when making the top and bottom overlays.

The internal layers do not have the silkscreens as it will make them invisible.

If you plan on not including texts on the board, this layer is optional.

However, the texts are helpful when debugging the RO4233 PCB in labs.

For example, find the text “R2” when you need to find out the potential of a single terminal of resistor R2.

The text allows one to easily find these parts.

When you have no texts, you need to refer to the designs.

Print blank boxes to enable revisions and serial numbers.

This allows one to write them using a sharpie or use a stamp on the board.

Solder Mask Layers

These are some odd thin and green protective coverings on the top and bottom of the PCB.

They will protect the traces from shorting where there is debris on the PCB.

Not all PCBs have a solder mask layer.

Some are on the top part and others on the bottom part only.

When using a solder mask, provide files for all the layers where you need to achieve this effect.

Also, solder masks are negatives meaning the areas you will not cover will have a solder mask layer.

Solder Paste Layers

This is a material you will use during the soldering surface mounts component on PCB.

Pads on surface mounts components will influence solder paste on the open copper area having no solder mask.

The solder paste comes in handy when the board has several surface mount components.

Solder paste will assist the solder to flow better when it sticks the component pin to the copper on the PCB.

Use a solder paste file on both the top and bottom sides of the design when using surface mount components.

How can you Prevent RO4233 PCB Material from Overheating?

A RO4233 PCB can withstand certain amounts of heat.

The performance of the RO4233 PCB will decrease when the temperature surpasses this limit, especially at higher temperatures.

Engineers need to prioritize the heat management system as the heat originates from several sources.

Since the PCB is small and light, the density of the components can produce heat, together with exterior sources.

The RO4233 PCB may distort as the heat makes it expand, and smaller electronic devices may encourage this effect.

A high dielectric constant in RO4233 PCB can assist with this matter.

Materials on the PCB may expand at different rates, and the coefficient of thermal expansion [CTE] defines it.

Some options of preventing overheating are:



Using Heavier Copper

This means placing traces deeper into the RO4233 PCB.

Therefore, the heat will disperse into the PCB and inside thermal vias.

This means using a thicker RO4233 PCB, which is beneficial in high-current equipment.

Thicker boards need more thermal energy to achieve a high temperature.

This assists in keeping the temperature on the top of the board to a minimum.

Integrate a Heat Pipe

This is suitable for compact devices like a smartphone, and it is a cost-effective passive heat transfer technique.

Also, it provides better thermal conductivity, vibration-free usage, and no moving components.

The pipe can hold small amounts of fluids like sodium, acetone, water, nitrogen, or ammonia.

The fluid absorbs heat, evaporates, then cools as it reaches a cooler region of the pipe.

Apply Thermal Interface Materials (TIM)

These materials will fill empty spaces between surfaces, which offer a great thermal conductivity than air.

This means the heat transfer between these two surfaces will improve.

Thermal interface materials will provide 100 times better heat conductivity than air.

The electronic industry uses thermal greases as they improve the performance of heat sinks.

Integrate an Active Cooling System

This can be a micro fan that will cool the device.

These cooling fans are the best since the size or voltage of the application does not matter.

The noise the fan produces depends on its size and how fast it spins.

Faster fans will produce more noise.

It is possible to alter fans by using insulating ducts, installing sound-dampening products, or using a rubber on the fan.

What are the IPC Assembly Standards used to Manufacture RO4233 PCB Material?

An IPC standard covers:

  • The handling techniques of the electronic assemblies
  • Acceptable installation methods for hardware on assemblies.
  • The acceptable results from soldering.
  • Manufacture of surface mounts, through-hole technology, etc.

Here are the IPC assembly standards:

  • IPC/WHMA-A-620C

This is the Requirements and Acceptance for Cables and Wire Harness Assemblies.

The CM is to use this standard to manufacture cables as per your specific PCB assemblies.

  • IPC 7711/7721C

This is the Rework, Modification, and Repair of Electronic Assemblies.

Use the information in this document to repair and rework PCBAs to IPC standards.

  • IPC-A-600

This is the Acceptability of Printed Boards.

When blank boards come from a PCB fabricator, this standard will inspect these boards.

  • IPC-A-630

This is the Acceptability Standard for Manufacture, Inspection, and Testing of Electronic Enclosures.

The CM uses this standard when assembling and inspecting the box builds.

What are the Components of RO4233 PCB Material?

The three components that make up RO4233 material are:


This is a B stage material that is sticky and enables the bonding of various laminates or foils.

Copper Foil

These are the conductive traces on the RO4233 PCB.

Copper Laminates [Core]

This contains prepregs and copper coils that you will laminate and cure.

How does a Two Layer and Four Layer RO4233 PCB compare?

Here is how these two compare:


It is possible to demarcate a 2-layer RO4233 PCB as the top layer is the signal layer.

A 4-layer RO4233 PCB comes with two inner layers which are between the top and bottom layers.


A 2-layer RO4233 PCB offers more surface when it comes to housing conductor patterns.

Vias will create electrical networks that route traces enabling them to reach the other side of the board.

A 4-layer RO4233 PCB design has prepreg layers that hold two or more two-side boards.

It holds them when you apply heat and pressure.


When using a microstrip trace that has a ground place, 2-layer RO4233 PCB is functional.

Besides, most manufacturers prefer 4-layer PCB that has a ground, VCC plane layer, and double signal layers.

However, this design will contest with propagation delays and impedance.


A 4-layer RO4233 is expensive since the design is complex and it has a high sensitivity.

Despite the cost, manufacturers are opting for 4-layer RO4233 PCB.

This is because they offer a high signal integrity level with a low interference level.

Manufacture of Prototypes

It is simpler to prototype a 2-layer than a 4-layer RO4233 PCB.

However, Gerber, an example of automatic software, can hasten this process.

What Properties Should you Consider when Choosing RO4233 PCB Laminate?

RO4233 PCB laminate comes with dielectric materials.

The properties worth considering are:

Thermal Conductivity (k)

This defines the capability of a material to conduct heat.

Low thermal conductivity relates to low heat transfer.

High thermal conductivity relates to high heat transfer.

The SI unit is in Watts/meter Kelvin [W/mK].

Glass Transition Temperature (Tg)

This is the temperature where the PCB substrate will change from a glassy rigid state into a soft deformable state.

The SI unit of Tg is in Degree Celsius [°C].

Decomposition Temperature (Td)

This is the temperature where the material will chemically decompose.

The SI unit is in Degree Celsius [°C].

Loss Tangent (tanδ) or Dissipation Factor (Df)

This is the tangent of the phase angle that is between the dielectric’s resistive and reactive currents.

Dielectric loss increases with an increase of the dissipation factor.

A low dissipation factor produces fast substrates, while large dissipation factors produce slow substrates.

Coefficient of Thermal Expansion (CTE)

This is the rate at which a PCB material will expand when it heats up.

The expression is in parts per million [ppm] that expands for each degree Celsius of heat.

The SI unit is PPM/°C.

When the temperature of the material rises over Tg, the CTE will rise.

Dielectric Constant (Dk) or Relative Permeability (Er)

This is the ratio of the material’s electric permeability to the free spaces’ electric permeability.
