How do you use Solder Mask on Rogers 4003 PCB?

Solder mask is made of a thin layer of polymer that prevent the copper conductors from getting oxidized.

It also prevents short circuits in the PCB.

You should note that the use of a solder mask is not mandatory for Roger 4003 PCB.

Despite the provision of protection to the PCB, the solder mask can also negatively affect the performance of higher frequency PCBs.

You can use solder masks to protect PCB areas that do not need any final plating finish.

The PCB conductor thickness, components to be attached, via holes and current density determines the specifications of the solder mask of choice.

You can use the liquid form, or dry (film) form solder mask.

However, the liquid form has superior and practical surface coverage on 3D surfaces.

The use of a solder mask does not necessarily enhance the performance of the PCB but brings its additions such as low moisture absorption and high dissipation factor.

A good solder mask should possess the following characteristics:

  • High adhesion
  • High electrical insulation
  • The resistance to all forms of plating should be high.
  • Longer shelf life
  • Excellent heat resistance
  • Comply with the halogen-free specifications

You should note that the colour of a solder mask can slightly influence the Df and Dk of the PCB laminate in performance-sensitive applications.

For good results, ensure that you thoroughly clean the surface of the Roger 4003 PCB before applying the solder mask.

How do you Produce Rogers 4003 PCB?

You can fabricate a Roger 4003 PCB by following the procedures below.

PCB layout

PCB Layout

· PCB Layout

Organizing and inspecting your Roger 4003 PCB design should be your first step in fabricating the PCB.

If you are making a homemade PCB, then you can print the PCB design created using CAD software on a piece of paper and transfer it on a copper-clad laminate.

For largescale factory production, you photocopy the design and print it on a film.

Arrange the photocopied pieces in the order in the case of multilayered PCB.

Align the printed PCB by aligning the holes followed by the materials for fabricating each layer as per the hole alignment.

· Production of the Core Board

You will begin core production by transferring the inner PCB layout.

First, construct the two most inner core layers.

Clean the copper clad layer, place a photosensitive film on the surface then expose it to light for curing and formation of a protective layer over the copper foil in the copper clad.

Insert the copper clad boards and PCB layout films into the upper layer of the PCB layout.

It accurately stacks the upper and lower PCB layout films.

· Inner Core Plate Etching

Use a strong base such as NaOH to etch away the unwanted copper foil then tear off the cured photosensitive film to required PCB layout copper foil.

· Punching and Inspecting the Core Plate

This step makes holes on the core board then aligns them facilitate compatibility with other materials to be attached.

An automatic machine inspects by comparing the pressed PCB to the original drawing and checks for any errors.

You have completed the first two layers.

· Laminate

You will need a prepreg during this stage.

It is a core and core board and binds the outer layer of the copper foil and the core board.

It also acts as an insulation material.

Alignment of holes and lower iron plate helps fix the layers of prepreg and lower layer of copper foil.

Place the prepared core plate on the alignment hole, followed by the two layers of prepreg, copper foil layer, and finally cover the core with a layer of pressure-bearing aluminium plate.

Use a machine to compress the stack up and which also fixes them using nails.

Transfer the compressed PCB to a vacuum hot press which laminates by holding the copper foil and core under pressure and melting the epoxy.

Remove the covering aluminium foil and iron plates to remain with a PCB covered with smooth copper foils.

· Drilling

Drilling helps connect different layers of the PCB.

You drill down a perforation hole from the top layer of the PCB to the bottom layer then metalize the hole to make it conduct electricity.

Using X-ray drilling machine helps align the drilling to the holes in the core board, ensuring the next drill hole goes through the centre of the hole.

You can place several similar PCBs and drill simultaneously since the process is very slow.

· Copper Chemical Precipitation of Pore Walls

It is a machine controlled process and necessary for connecting the walls of PCB using 25-micron size copper film.

Using chemical deposition, cover the hole with a conductive layer then spread a 1-micron copper film to cover the entire PCB surface plus the hole.

What are the Surface Finishing Options available for Rogers 4003 PCB?

Surface finishing ensures that your Roger 4003 PCB is protected from degrading environmental conditions.

It also provides a smooth surface for the attachment of other components.

Different types of PCB surface finishing significantly vary in costs, flatness, shelf life and reliability.

They also differ on the benefits they bring aboard, and their efficacy is application dependent.

You can use either of the following surface finishing techniques on your Roger 4003 PCB depending on the requirements of your application.

  • Electroless-nickel-palladium-immersion gold (ENIPIG)
  • Organic surface protectants (OSP)
  • Electroless-nickel-immersion gold (ENIG)
  • Solder mask

Can you make Multilayer PCB with Rogers 4003 PCB?

Yes, you can make a multilayered Roger PCB.

Depending on your system requirements, you can have your multilayered PCB fabricated with pure Roger 4003 laminate or have a hybrid Rodger 4003 + FR 4 PCB.

The combination yields a high-performance PCB that is less costly compared to all layered Roger 4003 PCB.

Ensure that you place the signal on the Rodger PCB core rather than on the prepreg.

How does Rogers 4003 PCB compare to other Series of Rogers PCBs?

There isa slight difference between Rodger 4003 PCB and other series of Roger PCBs in performance and parameters.

Compared to a closely related product Roger 4350B PCB, designed as a drop-in replacement for 4003 materials, there are minimal differences in performance.

However, the most significant difference comes in UL 94V-0 flame retardant certification.

While Roger4350 PCB is certified for UL 94V-0 since it uses flame retardant technology that is compliant to RoHS, Roger 4003 PCB is not UL 94V-0 rated.

It will burn when exposed to too high temperatures.

However, Roger 4003 PCB is constructed using an environmentally friendly material that is halogen-free compliant than Rodger 4350B PCB.

How does Rogers 4003 PCB compare to FR4?

The main difference between Roger PCB and FR 4 PCB is the material of construction.

Whereas Roger 4003 PCB laminate is constructed using a RO 4003 material that is composed of woven glass reinforced with hydrocarbon.

FR 4 comprises woven fibreglass that has been bonded by a flame-resistant epoxy resin.

Other notable differences include:

  • Roger 4003 PCB cost higher than pure FR-4 PCB
  • Roger 4003 PCB has superior performance for applications requiring higher frequency.
  • Roger 4003 PCB has a lower Df than FR 4 PCB and will experience a minimal signal loss than the later.
  • Roger 4003 PCBs has lower variation than FR 4 PCBs and therefore ideal for temperature-sensitive systems that require strict temperature management.
  • The transition temperature of Roger 4003 PCB is greater than 280°C compared to FR 4 PCB whose transition temperature range from 135°C to 180°C

How much does Rogers 4003 PCB Cost?

The retail price of Roger 4003 PCB significantly varies to the size, number of layers, specifications like the type of surface finish, and application, among other factors.

The cost will also depend on the quantity you are purchasing, and you are likely to receive a higher discount when you order a large number.

The PCBs will cost as little as $1.10 to above $50.0 per piece.

Before ordering, check to see the minimum quantity you can order from the supplier.

What are the PCB Fabrication Guidelines for Rogers 4003 PCB?

You can use the guidelines outlined for the fabrication of RO 4000 series PCBs while constructing Rogers 4003 PCBs.

They include:

· Drilling

You should use entry and exit materials that are rigid and flat to lower effects of copper burrs.

Ideal entry material can be a rigid composite board or aluminium while a standard exit material can have or lack aluminium cladding.

Ensure that the thickness of the material you are drilling is less 70% the flute length.

Avoid using chip lead less than 0.05mm and surface speed exceeding 500 SFM.

You should use the hole quality rather than tool ware to determine the useful life of the tool.

The hole roughness of RO 4003 material should not significantly increase with rising tool wear.

· Copper Plating

You should process the board using standard epoxy/glass processes and don’t apply any special treatment before electroless plating.

Remove the resins using double pass through alkaline permanganate or by use of conventional CF4/O2 plasma cycle.

· Etching/Imaging

You can prepare the panel surface for photoresist, either chemically or mechanically.

You can use semi-aqueous or aqueous photoresist.

· SolderMask

Do not mechanically scrub the exposed dielectric surface before you apply the solder mask since you can achieve maximum bonding with an “as etched” surface.

You can use any screenable type of solder mask compatible with glass/epoxy laminate on Roger 4003 PCB.

· HASL and REFLOW

You can bake RO 4003 material at a temperature range between 121°C to 149°C for 1-2 hours.

However, take care when the process is using infrared units that can reach up to 371°C.

The RO 4003 lacks fire retardants and will burn at such high temperatures.

· Shelf Life

You can store Roger 4003 PCB indefinitely at ambient room temperature conditions between 13 to 30°C, and humidity.

Avoid high humid conditions that will readily oxidize metal claddings which are otherwise inert at lower ambient room humidity.

· Routing

You can use machine RO 4003 materials using standard conditions suitable for epoxy/glass and carbide tools.

To prevent burring, you should etch copper foils away from routing channels.

You should also maintain the maximum stack height below 70% of the flute length to ease removal of debris.

How do you Test Rogers 4003 PCB?

You should test all the parts and components of the PCB because each has an overall impact on PCB performance.

You can conduct the majority of the PCB test following standard PCB testing specifications provided by the Institute of Printed Circuits.

Some of the common IPC standards include MIL-P-50884, MIL-PRF-31032, MIL-PRF-55110, IPC-6013, IPC-6012, IPC-6016, and IPC-6018, among others.

These standards provide guidelines on testing for major PCB properties such as mechanical strength, electrical conductivity, cleanliness, and lamination-peel strength.

Other crucial properties include soldering quality, hole wall quality alignment, orientation, compatibility to target environment etc.

You can use either of the following testing techniques:

  • In-circuit testing (ICT)
