Regular vs. Advanced
The most common substrate material for PCBs is the FR-4. The FR-4 is a fibreglass epoxy resin material. It is fire resistant hence the designation FR.
It was preceded in use by the FR-2. The FR-2 boards were pressed phenolic cotton paper. The FR-2 boards were replaced with the now more common FR-4.
However, with the demand for increasing complexity PCBs, PCBs made of FR-4 are simply no longer adequate to meet these demands.
There are certain properties of FR-4 that have made it unsuitable for use in complex design PCBs.
Two of such properties are its dielectric property and thermal conductivity. FR-4 is a material that has a high dielectric constant.
The dielectric constant measures the polarizing property of an insulator in an electric field. For the FR-4 material, the dielectric constant measures at 4.5.
This characteristic of the FR-4 causes signal loss in the PCB at high frequencies making it unacceptable in high-frequency PCB fabrication.
Another limiting property of the FR-4 is its thermal conductivity. It cannot tolerate high temperatures making unsuitable for advanced PCBs. Other limiting properties of the FR-4 are in its tensile strength, shear strength, dielectric breakdown voltage, glass transition temperature, leakage current.
This reality has led to the use of specialized kinds of materials that can deliver on these required qualities.
One material that when coated upon surfaces can fulfil these requirements is PTFE Polytetrafluoroethylene.
PTFE finds use in many everyday and industrial applications. It is very common in the food industry.
Commonly used as the substance to coat pots and pans giving them the non-stick property. It also found in lubricants where it serves to reduce friction.
It also finds use in solar panels giving it that self-cleaning property because coated on it, dirt and other unwanted materials wash away easily from its surface.
As a PCB laminate material, it has a low dielectric constant and impressive thermal conductivity.
This means that it is suitable for PCBs that require high frequencies like the RF and Microwave PCBs.
At high frequencies, PTFE coated PCBs record little to no signal loss, and at high temperatures, it absorbs heat effectively without the attendant heat degradation.
RF and Microwave PCBs, amongst other advanced PCBs, require high-frequency laminate materials.
RF and Microwave PCBs are finding popularity in 5G telecommunications gadgets and military radars.
These PCBs need specialized electrical and thermal properties. Hence, other types of materials which deliver on the necessary characteristics have been developed for use in advanced PCBs.
PTFE is produced and marketed by several companies. It s trademarked by DuPont as Teflon.
Teflon is its most common name. PTFE is also produced by another supplier called Taconic. Taconic has championed the use of PTFE in different areas like food processing.
The Advanced Dielectric Division focuses on the supply of materials for use in advanced PCBs.
Another company championing the use of PTFE as laminate material for PCBs is Rogers. Laminate materials have from Rogers carry the RO designation and have a wide range of laminate materials in its catalogue.
These high-technology PCBs also require specialized engineering experience in their design and construction.
For instance, they must have low thermal conductivity, tighter impedance tolerances – the combination of the capacitance and inductance at high frequency – than the regular boards.
It takes a specialized understanding of materials, their properties and how they can fit the design need.
Therefore, any innovation company that requires a board for specialized high-frequency laminates must seek out PCB companies that are specialized in the handling of such materials.
The companies showcased in this article boasts excelled engineering design teams. They assess projects and innovation both from the needs, materials and cost required to ensure their clients are afforded quality designs, appropriate materials to fit these designs and cost benefits to ensure products hit the markets at fair and profitable prices.
This article will take a look at some Taconic PCB manufacturers. It will also take a look at some other specialized materials supplied by specialized companies and PCB manufacturers with the required engineering skill sets that can handle these materials.
