Which is the Best Technique of Performing Teflon PCB Surface Preparation?

Surface preparation is one of the important steps in fabrication of Teflon PCB.

The substrate surface is made ready for marking formation of layer and metallization.

Careful consideration needs to be given to the type of machine utilized for surface preparation of Teflon due to its soft nature.

For example, you cannot utilize bristles, composite brushes, or pumice scrubbers in surface preparation since they can deform the soft PCB laminate dimensions.

Teflon PCB surface preparation is commonly done using sodium etchants or plasma gas cycling:

  • Sodium etchants can guarantee total removal of fluorine atoms off the surface of Teflon PCB laminate, and extend hold times post-processing.
  • Hydrogen in applied in plasma gas recycling due to its minute atomic nucleus together with its capability to eliminate fluorine by a strong reaction.

How is Teflon PCB Laminated?

Unlike FR4 PCB laminates, there is no need of oxide pre-treatment in PTFE PCB substrates.

Lamination of Teflon PCB materials and copper films can be performed at temperatures of 700F and pressures of 450-500 psi without bonding films or prepregs.

Sometimes, Teflon PCB manufacturers utilize bonding films or prepregs with low melting point.

This helps in reducing the processing temperatures to 425 or 250 degree Fahrenheit.

In addition, some hybrid Teflon PCBs use PTFE-FR4, though these need oxide pretreatment.

Which are the Features of High Frequency Teflon PCB?

  • Low water absorptivity since high water absorptivity can influence Df and Dk when in a moist environment.
  • Good chemical resistance, chemical resistance, peel-off resistance and impact endurance.

What is the Process of Fabricating Multilayer Teflon PCB?

Multilayer PCB

Multilayer PCB

The lamination of multilayer PTFE PCB is sequential procedure.

This implies that the base layer will be a copper foil sheet covered by prepreg layers.

The amount of prepreg layers differ based on the operational needs.

Further, the internal core, which is covered using layers of prepreg with copper foil, is settled on the base prepreg layer.

The forms a single laminate of the Teflon PCB stack.

Similar laminates piled up, one over the other.

After adding the last foil, it creates the ultimate PTFE lamination stack, known as a “Book”, with each PCB laminate called as “Chapter”.

The book is then taken to a hydraulic press, which is heated and puts substantial amount of vacuum and pressure on the book.

This procedure is referred to as curing since it compresses the laminates against one another.

The compression enables the prepreg resin to fuse with foil and core.

After removing the Teflon PCB assembly from the hydraulic press, it is then cooled down at room temperature.

The cooling enables settlement of resin, making the last step of manufacturing

multilayer Teflon PCB.

Though majority of multilayer PTFE manufacturing follow similar process, the result is not restricted to the procedure itself.

It calls for serious attention to detail.

For that matter, it is crucial to work with the right manufacturer of Teflon multilayer PCB.

Which is the Best Tool for Drill Teflon PCB?

It is recommended to utilize a new tool during drilling of Teflon substrates laminated using copper.

At a great chip load, the tool needs to have a slow in feed.

Multilayer Teflon PCB

Multilayer Teflon PCB

Internal Layers

Apart from outer layers, Teflon PCB features various copper laminates between the bottom and top layers.

These copper sheets are referred to as internal layers.

At times, inner layers employ copper pour method to develop a ground plane or power plane.

This method minimizes the quantity of etchant utilized in the process of manufacturing and equally help in the process of layer-to-layer bonding.

The thickness and weight of copper are determined depending on the specifications of the Teflon PCB.

The weight of copper within the internal layer determines the minimum width and space that can be fabricated.

External Layers

Often referred to as outer copper layer, the external layers is where the PCB components are attached.

The components including diodes, transistors, capacitors, resistors and more are installed through soldering into thru-holes or surface mount technology (SMT).

The outer layer comprise of a copper foil that is eventually electroplated using copper.

The electroplating assist in increasing the thickness and add more copper to the barrels of through-hole.

The final thickness of copper is customizable depending on the applications of Teflon PCB.

What is the Importance of Copper Plating in Teflon PCB?

Copper plating of PTFE PCB requires special consideration.

Pure Teflon PCB laminates feature a high Z-axis coefficient of thermal expansion, making copper plating on the walls of thru-hole necessary.

The copper used in plating should possess high tensile strength.

Copper having tensile strength features high ductility that assists in minimizing possibilities of pad lifts, blistering and barrel cracks on the PCB.

This elements lower modulus of elasticity.

Which are the Different Types of Layers in Teflon PCB Inner Layer?

With inner layers of Teflon PCB, every layer has unique functions and properties.

Some or all of the different types of internal layers of PCB may be applied based on the circuit board design:

V-groove Panelization

In this technique, the PCB is cut with a top to bottom thickness of 1/3 utilizing a 30 to 45 degree circular shaped blade.

A machine is then used to depanel the remaining board. This method is suitable when there exist no overhanging parts.

V-groove panelization technique is appropriate for scoring square and rectangular shaped Teflon PCBs.

It helps prevent strain on the printed circuit board.

Tab Route Panelization

This method of panelizing PCBs leave spaces between surface mounted components, perforated tabs, and the traces.

The panelization technique is done on Teflon PCBs with similar or different designs.

It aids in preventing possibilities of splintering and reduce surface stress.

Tab route PCB panelization is not suitable for heavy duty applications such as transformers or large relays.

Tiny laminate lumps might remain during separation, which are often sanded to attain smooth PCB margins.

Perforated Tabs

In this method of panelization, tiny holes are perforated in tabs.

These holes are at times referred to as mouse bites because of their smaller size.

The tiny holes facilitates easier depanelization of independent PCBs.

In perforated tab panelization, sanding is necessary since some material are left on the edges of PCB.

Similar to Tab route panelization method, this technique is equally not appropriate for heavy components.

Therefore, the best method of Teflon PCB panelization depends on the required edge profile and dimensions of PCB.

How do you Improve Adhesion of Solder Mask on Teflon PCB?

Double sided TEFLON pcb

Double sided Teflon PCB
