What Are the Basic Fabrication Guidelines for RO 5880 PCB Laminates?

You should always follow the fabrication guidelines provided by Rogers Cooperation when working RO 5880 PCB material for either single- or double-sided PCB constructions.

They include:

· Surface Preparation

You should prepare the surface of the RO 5880 laminate just before drilling in a double-sided process and before the final cleaning in a single-sided process.

Wear nylon gloves and then remove the self-adhering polythene sheets and any adhesive residues accordingly.

Remove the adhesive residues by wiping the laminate’s surface with a cloth soaked in alcohol then rinse with clean water.

Use microetchants and commercial cleaners to remove copper oxides.

Avoid mechanical surface cleaning methods such as abrasive cleaning because they will cause micro-scratches in copper.

If you have to use abrasive cleaning methods, then apply the least pressure possible to avoid extensive material distortion.

  • Tooling holes

Follow standard/normal procedures to punch, drill, and rout pinning/tooling holes.

  • Drilling

Avoiding Smear

Smearing can be very problematic for PTFE composite laminates such as RO 5880.

You should use the conservative tool life and employ very tight and controlled drill parameters to avoid smear which cannot be removed.

However, you can use the vapor honing technique to dislodge the re-deposited debris.

Stack Construction

You should use phenolic composite boards that have been pressed as entry/exit material when drilling RO 5880 laminates, either individually or in stacks.

Keep your maximum stack height below 0.240 inches.

The core material and entry/exit material’s combined thickness must be below 75% of the flute length of the drill.

Drill Type

Use carbide drills to reduce the wear of the cutting edge.

You can use standard style drills that have a 130° lip angle.

To reduce re-deposited smear, use undercut drills that have 0.025” reduced flute diameter from the cutting end.

Always use new drills for optimal results.

Drill Parameters

Use optimal tool surface speed of between 150 to 250 SFM and optimal infeed rates of between 0.0015” to 0.0025” per revolution.

Maintain a retraction rate of between 400-500 IPM and change the drill bits every 12” of dielectric material drilled.

Deburring

Reduce the potential risk of copper deburring by using flat, rigid, entry, and exit materials that have conservative drilling parameters.

Also, Keep the hit counts to the minimum by using new drills.

Always select chemical preparations but if you use mechanical or hand pumice scrubbing, apply minimal force to avoid distorting the laminate.

Hole Preparation

Use hydro- or vapor honing technique to remove re-deposited debris in the holes.

Ensure that you provide sufficient support because RO 5880 material is soft and can easily damage.

Treat RO 5880 laminate using either plasma or sodium treatment before depositing a conductive seed layer to prevent plating voids and poor metal adhesion.

Sodium treatments provide superior results for RO 5880 and will efficiently wet the material’s surface before depositing the metal.

Otherwise, you should only consider plasma treatment where you are going to use direct metallization instead of electrodeposited copper.

  • Metallization

Following a successful surface treatment, deposit the conductive seed layer using either electroless copper process or its alternatives at low to regular rates.

  • External Circuitization

You can use the conventional patter plates process for the following:

Photoresist Application/Imaging/Developing

Preferably, use chemical preparation methods which include Microtech and cleaners then apply the photoresists following standard processes.

Electroplating Cu & Sn/Pb or Sn

Handle your panels with care and consider using conventional electroplating techniques.

Resist Strip, Cu Etch, Sn or Sn/Pb Strip

Use standard strip solutions and etchants.

Ensure that you provide sufficient support for thin cores through the conveyorized processes.

Soldermask Application

You can use standard photo imageable solder masks because they provide sufficient adhesion.

Otherwise, use epoxy-based solder masks if it is to be selectively silver screened.

Final Metal Surface

You can use normal procedures with all final surface preparation options available.

Final Circuitization

You can rout, score, or punch the RO 5880 laminate in diverse ways depending on the desired edge quality.

Preferably, use spiral-up end mills and carbide double-fluted.

Also, use router bit design and not fishtail end.

What Storage Conditions Are Suitable for RO 5880 PCB Laminates?

Rogers PCB

Rogers PCB

You can store RO 5880 PCB laminate indefinitely under normal room humidity and ambient room temperatures of between 18°C to 30°C.

RO 5880 dielectric material will withstand atmospheric contaminants and high humidity at room temperature.

However, directly exposing the dielectric material to marine salts, sulfur oxides, and high humidity will oxidize and corrode the metal claddings.

Store the materials together with the polyethylene bags for thin cores and self-adhering polyethylene for the thick cores.

The covers will enhance protection against corrosive atmosphere.

You can either store the RO 5880 PCB laminates in the original shipping container or remove them from the shipping container and store them separately.

Storage in the Original Shipping Container

  • Store the materials as carton stacks on a flat surface and away from moving equipment.
  • Don’t exceed five carton stacks high to prevent applying excessive pressure on the lowermost carton.

Storage Out of Cartons

  • Store the panels together with the adherent and sealing polyethylene bags to protect the material against mechanical damages, corrosion, and oxidation.
  • To provide ease of access and limit the risk of damage, store the materials on edge of slotted shelves, and keep the clad surface vertical.
  • In case you cannot vertically store the laminates, then ensure that:
    • The shelves have a smooth, flat, clean surface.
    • The shelf’s surface must be larger than that of the laminate.
    • Keep the surface of the dielectric material free of debris.
    • Use soft and non-abrasive interleaving sheets to separate the laminates.
    • Maintain the shelf loading to below 50 pounds for each foot squared.

How Should You Handle RO 5880 PCB Materials?

RO 5880 is a PTFE-based material and thus more susceptible to handling damages like creases, pits, scratches, dents, etc.

Henceforth, you should follow the steps below to ascertain proper material handling.

  • Avoiding handling your panels using bare hands because the natural skin oil is slightly acidic and will easily corrode the surface of copper. Therefore, use gloves made of non-absorbent material like knit nylon.
  • In case you touch the laminates and leave behind fingerprints, then consider the steps below to remove them:
    • Dip brightly in a diluted hydrochloric acid
    • Remove the grease in methyl ethyl ketone, acetone, or in a chlorinated solvent (vapor degrease).
    • Rinse with water then dry bake at 125°C for 1 hour
    • Bright dip again
  • Remove all debris from the work surface. Also, keep it clean and dry.
  • Do not remove the polyethylene sheets and bags through the initial processing stages such as sawing, shearing, punching, and blanking.
  • Always pick your panels by two edges to avoid imparting permanent creases and material distortion. The thin cores are not strong enough to self-support.
  • Use flat carrying trays to transport your laminates between workstations during processing. Only use vertical stacks when they provide sufficient support and have slots. Also, interleave your laminates with sulfur-free and soft papers.

What Factors Should You Consider When Fabricating Multi-layer PCBs Using RO 5880 PCB Laminate?

RO 5880 PCB

RO 5880 PCB

You should consider the following factors when using RO 5880 PCB laminate when fabricating a multi-layer circuit board.

· Preparation of the Inner-layers

Use conventional etch and photoresist procedure.

Ensure that you maintain the as-etched dielectric surface to avoid the necessity of treating the surface with sodium treatment.

The adhesive system will influence the choice of a particular copper surface treatment.

· Adhesive Systems

You can use either thermoset or thermoplastics adhesive systems to bond RO 5880 multilayer PCB.

Use a thermoplastic adhesive system when your PCB electrical properties are critical and a thermoset system when the electrical properties are not as critical.

· Processing of the PCB Post-Bond

You can use the guidelines provided for processing double-sided circuits to process the outer-layer and prepare the multi-layer plated through-hole.

What Safety and Exposure Control Measures Should You Consider When Using RO 5880 PCB Laminate?

RO 5880 PCB laminate is safe for human health under normal operating conditions.

It is not classified as carcinogenic to humans.

However, machining may create dust which may cause respiratory irritation when inhaled, and mechanical irritation when it contacts the skin or eye.

Exposing the material to temperatures above the decomposition temperature will release toxic fumes that cause polymer fume fever in humans.

You don’t need to install any safety measures under normal working conditions.

For safety reasons, ensure that you always wear appropriate protective clothing to protect yourself against exposure when machining.

Use cut-resistant gloves to protect your hands and safety glasses that have side-shields to protect your eyes against dust.

Use MSHA/NIOSH approved respirators to protect yourself against inhalation of toxic fumes at high temperatures.

You should also install mechanical ventilation systems to reduce the effects of overexposure.

Install safety eyewash and showers in industrial operation areas for washing off dust in case of exposure.

Do not smoke or store smoking materials where machining and dust occurs.

  • First Aid

In the case of inhalation of fumes and dust, move to fresh air, and seek professional help on symptom persistence.

In case of eye contact with dust, use a large amount of water to flush the area for 15 to 20 minutes.

When the dust contacts the skin, remove the contaminated clothing then wash with plenty of water for 15 to 20 minutes.

How Can You Prevent Creep Formation on Your RO 5880 PCBs?

Rogers 5880 PCB

Rogers 5880 PCB

The Problem

RO 5880 has a greater Z-axis expansion compared to pure PTFE caused by the reinforcing fibers.

Though you can reduce the mismatch in bonded assemblies by clamping the board and hardware, the mismatch can still significantly affect performance.

When stress occurs in the presence of creep, thermoplastic materials might show a time-related relaxation.

The elastic recovery after removal of the stress/applied force also depends on time.

Both recovery and creep increase with an increase in temperature.

Creep can affect the attachment of hardware on the application by variation in temperatures.

A rise in temperature or decrease in temperature will either cause a maximum creep rate and increase stress or decrease stress thus leading to loosening.

Though the board’s compressive deformation sufficient for loosening to occur may be minimal, successive thermal cycles will eventually cause the material to loosen.

Solution

You can reduce the effect of creep formation by using long screws that have springs, for instance, Belleville washers’ stack.

It increases the elastic response range and reduces the hardware stiffness.

Furthermore, it minimizes the increase of stress at elevated temperatures and maintains tightness even in the presence of creep.

What Are the Properties of RO 5880 Copper Foils?

The standard copper foil for RO 5880 is ½ to 2 oz. electrodeposited copper foil clad on both sides but you can also get rolled copper foils.

The latter best befits applications with critical electrical requirements.

· Electrodeposited (ED) Copper Cladding

Electrodeposited copper foil the most conventional cladding used for RO 5880.

You will manufacture ED by depositing a solution of a specific current condition and voltage onto a slowly moving titanium drum.

You will then strip it from the drum.

ED forms a smooth and polished texture on the drum side but a dendritic ‘tooth’ grain structure on the opposite side or ‘bath side’ of copper.

Rolled Copper

The fabrication process of rolled copper follows continuous running of the copper strip through successively smaller gaps in the rolling mill.

The grain structure of rolled copper differs from that of ED and also has a smoother surface compared to ED copper.

You can enhance the smoothness of rolled copper through annealing.

The smooth surface of rolled copper makes it ideal for use in circuits with very low loss tangent.

The dissipation factor of rolled copper is lower compared to ED copper due to the ‘surface effect’ phenomenon.

Comparably, the surface of ED foil is rougher than that of rolled copper.

Henceforth, it produces longer ‘pathways’ for microwave frequencies than that of rolled copper thus exhibiting higher electrical loss.

Can You Use RO 5880 PCB Laminate for Space Applications?

Yes, RO 5880 is ideal for spacecraft applications because of its excellent thermal stability and outstanding resistance to outgassing.

What Is the Flammability Rating of RO 5880 PCB Laminate?

RO 5880 has a UL 94 flammability rating of V-0.

What is the Cost of RO 5880 PCB Laminate?

The cost of RO 5880 PCB laminate significantly varies from one vendor to the other.

Factors that will influence the cost are the dielectric thickness and tolerance, type and weight of copper foil, panel sizes, and volume of the consignment.

You can get a single piece of RO 5880 at a retail shop that ranges between US$0.10 and US$0.50.
