What should you Consider when Choosing Taconic Tly-5?

The following factors should be put into consideration when choosing Taconic tly-5:

• Glass transition temperature: This is the temperature at which high molecular weight materials change from a glass state to a viscous rubber state.

It is essential to put the temperature into consideration.

This is because the rigid Taconic tly-5 will stop working at this temperature and begin to soften.

• Thermal decomposition temperature: It varies depending on the type of PCB material.

For many epoxy systems, the temperature ranges between 300 degrees Celsius to 400 degrees Celsius. It is also the same temperature range for flexible Taconic tly-5 materials.

• Dielectric constant: this refers to the rate at which an electric signal travels in a dielectric material.

For high rate transmission, PCB boards must use laminates with a low Dk to achieve high frequency.

• Thermal expansion: thermal expansion refers to the ability to change its appearance due to a temperature change.

Taconic tly-5 may change their shape, area, or volume when the temperature exceeds the Tg value.

• Thermal conductivity: this is the ability of a material to conduct heat.

When choosing Taconic tly-5, consider those with copper and aluminum.

They have high thermal conductivity.

• RoHS compliant: this refers to the ‘green’ requirement driven by market considerations and policies.

What does the PCB Lamination Process Entail?

The PCB lamination process will vary depending on different types of PCBs and lamination specifications.

You can take a look at this:

· Double-sided PCBs

For double-sided PCBs, the lamination process is quite like other types of PCBs.

You should laminate a double-sided PCB panel using dry resist layer.

It should be photosensitive.

· Multilayer PCBs

Multilayer PCBs can either be thin etched boards or trace layers.

Either way, they both need bonding bay lamination.

Taconic laminates for multilayer PCB follows this procedure:

i. The internal layers of the multilayer PCB are usually subjected to an extreme temperature of 375 degrees Fahrenheit.

Also, it requires a pressure of between 275 to 400 psi.

ii. The multilayer PCB can cure as the temperature is kept high.

iii. Finally, slowly release the heat and cool the lamination material.

· Sequential Lamination

This lamination technology is useful if the PCB has two or more subsets.

After creating the subsets using a separate process, Interpose a dielectric substance between each pair of subsets.

Once done, carry out standard manufacturing procedures.

You should choose a lamination process that is suitable for the intricacies of your application.

What Determines the Thickness of Taconic Tly-5?

You can get the thickness of Taconic tly-5 using fabric and density weight calculation.

You should expect to get some variance in your calculation, as much as five percent.

Total weight is the most probable way of finding total Taconic tly-5 thickness.

A single fabric may possess a different finished weight.

This may bring about a variation in the thickness of the final product.

Therefore, to determine the accurate thickness of Taconic tly-5, you should always base your analysis on the final total weight.

How do you Choose the Glass Fabric used in Taconic Tly-5?

The choice of fiberglass used in Taconic tly-5 will depend on:

• Thickness that the fiberglass fabric will contribute to the finished Taconic laminate.
• Amount of resin that the fiberglass holds for filling and bonding.
• Thickness of the circuit board.
• The stiffness of the circuit board.
• Dielectric constant.
• CTE control
• Dimensional stability.
• The cost.

How do you Prevent Damage and Deformation of Taconic Tly-5?

You should observe the following:

• Do not scrub the material mechanically as this will stretch and deform it.

To avoid this, use chemical cleaning to achieve dimensional accuracy of the process and prevent distortion.

• It is not recommended to lift a Taconic laminate on one side as you may cause the material to slide or stretch the copper.

You should lift the Taconic Tly-5 using the two parallel edges.

• Prevent contaminant deposits and staining on the Taconic laminate by handling it using protective gloves and slip sheets.
• Do not put Taconic laminates on top of each other to avoid debris on the surface of the laminate.

What is the Importance of Copper Foil used in Taconic tly-5?

Some of the benefits of using copper foil on Taconic tly-5 include:

• It is used to carry signals from one part of the PCB to another.
• It serves as power and ground layers.
• It interconnects the various devices in the PCB, inputs, and outputs that make the PCB work in its application.
• The copper foil helps to carry away unwanted heat from power devices.

How do you Choose Copper Foil Type for Taconic Tly-5?

The copper foil type or weight will be dependent on the following factors:

• Power handling requirements: The board’s power handling requirements will determine the type of copper foil to use.

For high power applications, you should use thick copper foil.

Use the thin copper foils should if you have lower power applications.

• Size and spacing: use thinner copper foil when the lines spacing is narrow.

Sweeping lines and broader spacing, on the other hand, will require thicker copper foil.

• Characteristics impedance and loss of line: the cross-sectional area of the copper foil affects Taconic laminate thickness, and its dialectic constant.
• Heat: the amount of heat requirement will determine the copper foil type or weight.

This is even critical for inner layers.

Thicker copper foils have a higher capacity to dissipate heat as compared to thinner copper foils.

How much do Taconic Tly-5 cost?

Taconic tly-5 costs will vary depending on lamination, material categories, stability, and material category.

The price of Taconic tly-5 ranges between  $20 and $50 per piece.

Once you consider everything I have mentioned in this guide, you will definitely get high-performance Taconic Tly-5 material.
