How Should You Fabricate Arlon TC 350 Material?

You can use standard processing techniques for conventional PTFT ceramics laminates to fabricate Arlon TC 350 material.

· Armazenar

You should store TC 350 laminate away from direct sunlight in a cool, dry and flat place to prevent material contamination and copper oxidation.

· União

You can use FR-4 prepregs, Arlon’s 6250 or 6700 bonding films to bond Buried Microstrip and Stripline.

Also, you should immediately follow copper etching with direct lamination.

You can improve the laminate’s surface adhesion by applying plasma or sodium etch before bonding.

Besides, you can also enhance the adhesion of the copper surface with micro-etch before bonding.

· Perfuração

You should use carbide tools to drill the material and avoid repointed tools for best results.

You can stack panels and drill them together based on their total thickness.

For rigid entry and exit materials, use 0.20” to 0.30” and 0.60” to 0.93”.

The surface speed should vary between 400 to 450 surface feet/meet and the chip load between 0.002 to 0.003 inch/revolution.

The retract rate should be between 500 and 600 inches per minute, and the tool life will significantly vary from 500 to 1000 hits depending on stack height.

· Deburring

You will not need aggressive deburring if drilling is optimized otherwise, apply light circular motions using 600 grit sandpaper.

Ensure that you provide sufficient support to the panel’s backside before initiating the process.

Remove loose debris remaining in the holes by applying high-pressure sprays.

· Preparação do furo passante

Activate the hole wall resins using either sodium etchants or plasma for optimal coverage with depositions of electroless copper.

You should repeat the plasma process if the hold time exceeds 12 hours.

Also, you should rinse the laminate using organic solvents and hot water following the sodium’s vendor guidelines.

· Preparação da superfície

You should avoid mechanical scrubbing of the material to prevent any potential dimensional changes as a result of excess pressure on the copper surface.

Consequently, you will achieve satisfactory results by using standard chemical cleaning techniques.

· Chapeamento de Cobre

You can use either electrolytic copper chemistry and direct plate technologies or conventional electroless techniques.

· Gravura

You can remove unwanted copper by using cupric etchants or conventional ammoniacal. Apply sufficient water to rinse it thoroughly.

· Resist Strip

Remove unwanted resist by applying conventional resist strippers.

· Soldermask

For best adhesion results, you should apply the solder mask coating within 12 hours after copper etching.

Use sodium or plasma etch to prepare the laminate’s surface and micro-etch to prepare the copper’s surface to achieve improved solder mask adhesion.

· Hot Air Leveling

You should subject TC 350 boards to baking at temperatures between 110°C o 120°C before solder levelling.

For dissipation of any residual moisture, you should rack the boards to achieve sufficient air circulation around the pairs.

· Electroless Gold

Following the processing guidelines of your chemical vendor, ensure that you adequately rinse the material to deliver reliable process yield required for chemical plating.

· Roteamento

You can use the commercially available slow spiral, two-flute, micro-grain carbide, up cut end mills.

Before exerting sufficient clamping pressure on the material sack using an outer pressure, ensure that you provide adequate support to the material.

Typically, you should use the following routing parameters for an 0.062” cutting tool.

  • 15, 000rpm spindle speed
  • Feed rate: 15 inches per minute.

What Precaution Should You Undertake While Working with Arlon TC 350 Material?

You should always follow the safety guidelines information supplied by the product’s manufacturer every time you are working with Arlon TC350 laminate.

Below are some of the precautions you can take to ensure smooth and efficient operations.

  • Provide proper ventilation and wear appropriate work gear to protect yourself against nuisance dust generated from cutting and other finishing operations.

Dust will cause respiratory irritation, eye and skin irritation.

  • Avoid processing the material at temperatures beyond decomposition temperature as this will make the laminate release toxic fumes.

Inhalation of the fumes can cause symptoms resembling polymer or metal fume fever characterized by flu-like symptoms.

It should disappear within 24 hours but in case of a severe attack, always seek medical assistance.

  • The material will release toxic fumes in case of a fire breakout. The firefighters should be equipped with self-contained breathing air.
  • Do not dispose of the wastes or unused components or old Arlon TC 350 in sewer systems, soil or surface water.

Follow the appropriate regulatory guidelines for disposal.

  • Store the product in a cool, dry, and well-ventilated place.
  • Use a suitable respirator that meets the requirements of NIOSH when working under conditions that may generate heat and noticeable orders/irritation.
  • Also, put on complete gear covering the whole body, gloves, and safety glasses.
  • Ensure that you have a readily accessible eyewash area and safety showers.

How Much Can Arlon TC 350 Cost?

The price of Arlon TC 350 laminate varies to the panel size, cladding, thickness, and any other special consideration required.

You will also benefit from excellent discounted prices if you purchase in bulk.

The prices can vary from as low as $4 @ piece if you buy a minimum of 100 pieces.

How Long Can Arlon TC 350 Last?

Arlon TC 350 laminate is C-stage by nature and cannot advance further.

Hence, Arlon TC 350 laminate does not have a specified shelf life.

It can last an eternity if stored in a dry, cool, and clean environment.

However, you should always avoid storing laminates for extended periods since they can easily degrade to oxidizing environmental conditions.

In the case of extended storage, check to confirm that copper is not oxidized before using it.

Alternatively, you can use clean the copper using standard pre-cleaning techniques if it is not excessively oxidized.

These techniques will help you achieve the specifications initially stated for the intended use.

Can You Use Arlon TC 350 to Make a High-Frequency PCB?

Yes, Arlon TC 350 is a high-frequency material that offers a low loss and dielectric constant that remains stable across a wide range of temperature and frequency.

Arlon TC 350 PCB laminate offers superior thermal conductivity properties ideal for fabrication of highly reliable high power applications.

How Can You Enhance the Registration of Arlon TC 350?

You can enhance the registration of Arlon TC 350 by considering the tips below:

  • Match the board thickness requirements to the most dimensionally stable material.
  • Use heavyweight prepregs such as 2116 and 2313 where possible to enhance the stability of the entire system.
  • Handle all artwork in a controlled environment, that is, controlled humidity and temperature.
  • Ensure that you design the boards with consideration to register them. Do not use excess copper on one edge or the other on the inner layers.
  • Use a copper border to prevent distortion through enhanced stability.
  • You can use more pins to increase efficiency, especially for boards with solid copper borders.
  • Select the lowest lamination temperatures ideal for resin. Using higher temperatures will increase movements in the X-Y plane and increase stress on the board during cooling.
  • Subject the boards to below 5°C for cooling to prevent ‘locking in’ of unbalanced stress.

Why Should You Prefer Arlon TC 350 for Tower Top Electronics?

Tower top electronics such as tower mounted electronics, and wireless communication base stations have more complex systems and higher power density.

Consequently, these products require more reliable product designs.

However, such applications always suffer from component failure, especially the failure of power amplifiers, when fabricated using standard PTFT PCB.

Standard PCBs suffer double the failure rate or the mean time between failures (MTBF) is halved for every 10°C increase in operating temperature.

Arlon TC350 PCB laminate is a thermally conductive material that offers an ideal and cost-effective design for the reduction of device temperature.

This substrate can lower the steady-state temperature by approximately 8°C, enough to double the MTBF or cut the potential failure rate by half.

Consequently, superior thermal management offered by Arlon TC 350 PCB substrate will ensure efficient transistor operations and performance.

Can You Use a Metal Core in Arlon TC 350 PCB?

Yes, you can use metal cores in Arlon TC 350 PCB if you want to produce a PCB with very low CTE.

Select metal cores with low CTE to effectively reduce the board’s CTE and redirect heat from sensitive components.

You can use either carbon fiber composite cores of CIC.

However, you should take care when using CIC because further addition of a metal core constrainer in an already reinforced resin can result in excess Z-direction expansion.

To avoid the above problem, you can use aluminum or copper cores with an expansion of 23 ppm/°C and 17 ppm/°C, respectively.

These materials don’t add to extra expansion on the Z-direction.

What Are the Coefficient of Thermal Expansion of Materials used to Construct Arlon TC 350 PCB?

The Coefficient of Thermal Expansion (CTE) is the measure of a material expansion when subjected to heat.

Though the material expansion is volumetric, it is undesirable that a laminate or PCB only expands in the Z-direction and not in the X-Y direction.

Using reinforcing fabrics with lower CTE such as glass on Arlon TC 350 material restricts the system’s in-plane expansion.

Compared to other Arlon materials, Arlon TC 350 has a lower CTE value because of the low expansion filler technology used on its fabrication.

Consequently, Arlon TC 350 material has constituent woven fiberglass, ceramic filler, copper foil, and PTFT composite.

The CTE of these materials are as follows:

  • Copper foil: 17-18 ppm/°C
  • Fiberglass Fabric 5-6 ppm/°C
  • Fiberglass Fabric 5-6 ppm/°C

The CTE of the above pure materials will, however, change on a composite.

The composite CTE depends on several factors such as the individual component’s effective modulus in the form used.

Henceforth, you will need to perform actual testing and establish the ‘effective’ composite values and properties for use in modeling.

What Is Prepreg Flow? And How Does It Affect the Efficiency of Arlon TC 350 PCB?

Prepreg is the short form of ‘pre-impregnated.

It refers to fabric reinforcement saturated (impregnated) with epoxy, polyimide or any other partially cured resin during the coating process.

Prepreg flow happens when you heat the prepreg under pressure and cause the resin to melt into a liquid and flow.

The amount of prepreg flow will depend on the intensity of resin heat up and pressure.

Also, the flow can only last a limited period before gelling and is the basic principle behind lamination.

The rate of actual prepreg flow is critical in determining the quality and efficiency of lamination, and it significantly depends on laminating conditions.

The rate and quantity of actual prepreg flow determine fundamental PCB properties such as:

  • Interlaminar bond
  • Bond to the inner layer copper foils
  • Laminates bond to ED copper foil used to construct the laminate.
  • The efficiency of prepreg as ‘bonding sheet.’

To ensure consistency in the manufacture of quality products, you have to maintain consistent prepreg flow characteristics.

What Critical Process Parameters Should You Be Concerned Off When Fabricating Arlon TC 350?

You should pay close attention to the following five critical processes when fabricating your Arlon TC 350, though they are not laminate-specific. They include:

  • Ensure that the processed inner layer and the prepreg are dry before lamination.
  • You should maintain a consistent melt flow by controlling the laminating press heat-up rate.
  • You should laminate TC350 material at the product’s ideal lamination temperature.
  • You should maintain adequate cure time at a temperature sufficient for the development of Tg.
  • Control the cooldown to prevent warpage.
