How do you Cover and Fill Vias during Taconic PCB Fabrication?

Types of Vias

Types of vias

· Filling and Covering Vias

Filling a via should prevent the accumulation of chemicals and other materials in the holes, which may lead to faults to the PCB.

You can fill vias using either non-conductive or conductive paste, with via in pads and blind vias filled utilizing uniquely designed electroplating.

A conductive fill is the right choice in case you intend to transfer heat from one edge of the Taconic PCB to the other.

Moreover, you must cover or seal the vias using capped plating.

Vias must be sealed or covered by capped plating.

The blend of mechanical and sequential technology build-up can cause disturbance to the buried via plating, causing problems with the circuit board.

To avoid this problem, you should fill the vias with resin prior to plating.

Also, it is important to plate a via in pad since you are a module connection, yet you cannot have a recessed hole.

Are there Flexible Taconic PCB Laminates?

Yes, there are HyRelex Taconic PCB material that is category of los-loss, slim, flexible laminate.

They are used together with HyRelex cover-lay and bond-ply in various applications comprising of high-frequency circuit boards.

This type of PCB laminate is capable of maintaining its mechanical and electrical features in harsh environment applications.

The laminates have dielectric constants ranging from 2.60 to 2.90 coupled with closely paired cover-lays and bond-plies.

They can be as slim as 25 µm and come in a variety of copper styles.

Do Taconic PCB Materials allow Multilayer Capability?

Taconic PCB features myriad of materials that ensure high reliability and low loss traditional, high-speed digital and multilayer RF printed circuit board fabrication.

They use prepregs manufactured using woven fiberglass, PTFE components or BT epoxy offer ease of fabrication and minimized electrical loss.

These laminates, with a dielectric constant of 3.00 to 3.50, allow fabrication of multilayer Taconic PCB at FR-4 laminating pressures and temperatures.

Some use slim flexible interlink materials that ensure moisture, mechanical, and electrical resistant features for multilayer, double-faced and rigid flexible PCB.

Smooth surface profile, exceptional peel strength and low dissipation factor make them fit for harsh environments, high temperature and high frequencies PCB applications.

TSM-30, a type of Taconic PCB material, is engineered for uniform performance through wide frequencies and temperatures.

It provides low absorption of solvent and moisture and low loss.

Moreover, most multilayer Taconic PCBs employ thick metal clad laminates, which give thick aluminum, brass and copper for reliable temperature management.

What is the Difference Between Coefficient of Thermal Expansion and Loss Tangent of Taconic PCB?

Loss tangent (tanδ) refers to the signal power loss as it moves across a transmission line of a dielectric material.

Conversely, Coefficient of Thermal Expansion describes a material’s dimensional change as a reaction to temperature change.

Between Arlon PCB and Taconic PCB; Which PCB Material Guarantee High Performance?

Taconic PCB materials guarantee high performance in comparison to Arlon PCB materials, since they use PTFE and ceramic filled laminates.

Polytetrafluoroethylene (PTFE), a synthetic thermoplastic fluoropolymer with exceptional dielectric characteristics at microwave frequencies is the most common high-frequency PCB material.

Arlnol PCB

Arlon PCB

Low Z-axis CTE, low dielectric constant and thermally stable PTFE laminates are the main materials applied in the manufacture of microwave/RF circuit boards.

Most Taconic PCBs are engineered with very low fiberglass content to attain superior insertion loss features and uniform dielectric constant across the laminate.

Furthermore, the homogenous ceramic dispersion across the laminate results in ultra-low X and Y CTE.

Why is PTFE Material the Best for Taconic PCB Laminate?

PTFE Laminates are the better option since PTFE-based substances are not part of any present regulatory bans or guidelines.

Some of the reasons why of PTFE is the best Taconic PCB laminate include:

  • Thermal stability
  • Excellent electrical properties
  • Durable electrical features
  • Flame resistance

What is the Difference between Thermal Decomposition (Td) and Glass Transition Temperature (Tg) in Taconic PCB Fabrication?

Glass transition temperature refers to the temperature when the PCB material changes from a solid to a viscous state.

It is a very important factor to consider when choosing Taconic PCB material.

On the other hand, thermal decomposition temperature refers to the temperature when chemical decomposition of the material takes place.

How does Moisture Influence the Performance of Taconic PCB?

Humidity affect performance of PCB since water content of a Taconic PCB susceptible to moisture absorption can influence impedance stability and loss performance.

Most ordinary PCB laminates boast of 2 percent of more moisture absorption values.

This implies that the laminate may soak moisture up easily, changing its electrical properties.

In comparison to Taconic PCB materials, the dielectric constant of water is extremely high, around 70.

Therefore, in a high humidity environment, excessive absorption of moisture can raise the dielectric constant of PCB, thus raising its dielectric loss.

Typically, materials designed for high frequency applications normally feature low moisture absorption, having values of 0.2 percent or lower.

When should you use Rogers PCB instead of Taconic PCB?

Rogers PCB

Rogers PCB

Both Taconic PCB and Rodgers PCB are high-frequency laminates, with both found in the exceptionally low-loss group of laminates.

With respect to least incurring losses and highest efficiency, Rogers PCB laminates come second to Taconic laminates.

Although they are closely similar in terms of transmission and electrical properties, Rodgers PCB are ideal for lower frequency applications.

Moreover, they are fit for extreme heat PCB applications that need the use of ceramic laminates.

The materials are equally vital in minimizing electrical noise to satisfy stringent performance conditions.

What are the Key Considerations in Hybrid Construction of Taconic PCB?

Some of the main considerations during fabrication of hybrid Taconic PCB stack-ups include:

· Compatible Materials

The materials used in the hybrid stack-up must be compatible with the lamination cycle.

Certain materials require higher pressures and temperatures compared to others during the lamination process.

It is crucial to check the material data sheets to ascertain the use of compatible materials before submitting your design.

· Drill Parameters

This is an important factor because it dictates proper formation of hole.

The drill bits feeds and speeds differ depending on the stack-up materials.

You need to adjust the feeds and speeds in a hybrid construction.

For instance, some components dissipate too much heat and there can be some deformation when the material cannot endure heat.

Furthermore, it is important to note that different Taconic PCB materials drill differently.

· Hall Wall Preparation

After drilling of hole and prior to cuposit, comes hole wall preparation, and different materials need different plasma.

There may be process instructions per general group, however, for on-time delivery and absolute reliability, you need to refine the process per material.

Which are the Different Types of Lamination Methods used in Multilayer Taconic PCB Manufacturing?

The following are the commonly used methods in Taconic PCB lamination process:

1) Multiple Layer PCBs

As the name hints, these are circuit boards consisting of several layers, which can be either trace layers or thin etched boards.

In either case, the bonding is through lamination.

The interior PCB layers are subjected to extreme pressure and temperature during lamination.

The procedure is applied when laminating using a photosensitive dry resist.

Afterwards, the circuit board is permitted to cure at extreme temperature.

Eventually, there is gradual release of pressure leading to slow cooling of the lamination material.

2) Double-sided PCBs

Although the fabrication process of double-sided boards differ from other PCB types, the lamination process is relatively the same.

A layer of photosensitive dry resist is employed for the PCB panel lamination.

Similar to multilayer PCB, the procedure is performed under extreme pressure and temperature.

3) Sequential Lamination

Sequential Taconic PCB lamination technology is applied if the board consists of 2 or more subsets.

Multilayer PCB subsets are formed in different procedures.

Subsequently, a dielectric material is embedded between each subsets pair.

Standard fabrication procedures are executed after this operation.

4) PTFE Microwave Laminates

PTFE microwave laminates make part of the popularly utilized laminates for printed circuit board lamination.

This is because they have low electrical loss, tight thickness tolerance, and uniform dielectric constant.

These features make PTFE laminates perfect for RF PCB applications, with CTFE thermoplastic film being the common PTFE lamination material.

In summary, you should select an appropriate lamination method, based on the complexity of your application.

What is Insertion Loss in Taconic PCB?

The insertion loss is the total loss of a Taconic PCB transmission lines, which rises with signal frequency.

Based on the PCB design, higher insertion loss can result in a channel margin collapse.

The eye will be closed vertically with more attenuation.

As transitions gets less sharp, more horizontal eye closure will happen that may cause collapse of timing interval.

To tackle this problem, it is important to specify to your PCB supplier the maximal acceptable insertion loss.

Which Factors Affect the Insertion Loss of Taconic PCB?

You can minimize PCB insertion loss by:

  • Using broader traces
  • Ensuring looser coupling (bigger spacing between traces)
  • Incorporating thicker dielectrics (thicker layers and more prepreg/laminate layers)
  • Reducing the dielectric constant of the PCB material

The first two parameters tend to reduce routing density, which as a result always needs more board layers.

This can increase the cost of Taconic PCB.

Similarly, the third factor can as well drive coats up.

The last parameter means opting for more exotic PCB materials which equally increase cost.

Moreover, there are several additional factors that will influence insertion loss including:

  • Temperature
  • Trace surface roughness
  • Board topologies including type and number of connectors, back drilling, routing lengths, via effects, etc.
  • Humidity
  • Any variances and defects within the Taconic PCB

Which is the Transmission Line Technology commonly used in High-frequency Taconic PCB?

The frequency performance of printed circuit board materials are of great importance to RF and microwave Taconic PCB designers.

However, it may not be of serious concern when designing low frequency PCB.

Still, it is an aspect that must be understood whether engaged in low frequency or high frequency PCB design.

The three most popular transmission-line technologies applied in microwave Taconic PCB are stripline, microstrip and coplanar circuits.

Among the three circuits, the commonly employed in high-frequency Taconic PCBs is microstrip transmission lines.

This is because they are comparatively easy to fabricate and have minimal electrical parameters to consider compared to other two technologies.

Electromagnetic propagation within a microstrip circuitry happens through transverse-electromagnetic plane waves.

In a perfect microstrip circuitry, signal energy travel perpendicular to the magnetic and electric fields.

Conversely, in real microstrip circuitry, transmission occurs within the dielectric materials found between the conductors and within the air over the conductors.

This propagation takes place in a quasi-TEM manner.

Which are the Types of Signal Losses in High-frequency Taconic PCB?

PCB insertion loss

PCB insertion loss

Microstrip transmission line experiences four types of PCB signal losses: leakage, radio, dielectric and conductor losses.

Because of the high resistivity of Taconic PCB materials utilized in microwave circuits, leakage losses normally are not an issue.

Radio losses incline to be more of a concern for microstrip circuitry than for stripline or coplanar circuits.

The PCB substrate material determines the dielectric losses, you can use dissipation factor to compare the loss performance of different materials.

Lower dissipation factor values implies lower dielectric losses of the Taconic PCB laminate.

It is not that easy to evaluate conductor losses since they are connected to numerous different parameters within a microstrip circuitry.

Skin depth reduces with rising frequency, which in turn results in increase of conductor loss.

The impacts of roughness of copper conductor surface increase with increasing frequency until they hit a saturation point.

Does Environmental Conditions Affect the Impedance of Taconic PCB?

Environmental conditions can as well affect how well a Taconic PCB material retains impedance, particularly at higher frequencies.

Most traditional circuit board may lack the formulation for steady dielectric constant performance in hostile or changing environments.

However, all PCB materials feature a variable referred to as thermal coefficient of dielectric constant (tCDk), denoted ppm/degree Celsius.

It defines the degree of change in the dielectric constant with variations in temperature.

The variations in dk will as well result in variation of the microstrip transmission lines impedance, therefore, lower tCDk values are preferred.

How does Taconic PCB compare to Ventec PCB?

Ventec PCB

Ventec PCB

Both Taconic PCB and Ventec PCB are high-speed printed circuit boards, with the difference primarily in the materials they use.

As you already know, Taconic PCB mainly use PFTE and ceramic-filled laminates.

On the other hand, Ventec PCBs apply high performance, high-quality copper clad prepregs and laminates utilized in a myriad of PCB applications.
