Helicopter PCB: The Ultimate FAQ Guide

Helicopter-PCB-The-Ultimate-FAQ-Guide

In this guide, you will find all information you’re looking for about helicopter PCB.

Whether you want to learn about design, material type, components, features or specifications – you will find all information you have been looking for here.

So, before importing helicopter PCBs, read this guide.

What Is A Helicopter PCB?

It is a non-conductive material with conductive lines called traces engraved on it and electronic components mounted on it to make one package.

The board serves to mechanically and electrically hold components together to form a functioning circuitry for operating a particular part of a helicopter.

Which Are The Most Appropriate Helicopter PCB Substrate Materials?

Materials such as high temperature laminates, aluminium, and copper substrates that can withstand extreme conditions are used in making helicopter PCBs.

That is because helicopter PCBs are expected to remain reliable in extreme environmental conditions in which they operate.

Anodized aluminium can also be suitable in getting rid of the effects of heat induced oxidation.

Blending aluminium with thermally conductive pre-pregs also has lots of advantages in the design of helicopter PCBs.

Depending on the components or area of application, you can choose from a range of PCB materials such as:

What Are The Features of Helicopter PCB?

The most important features of helicopter PCBs include:

Highly Reliable In Extreme Conditions

PCBs stronger than the average ones used in other electronics are required in the aerospace industry to ensure reliability.

For instance, aluminium, copper, and high-temperature laminates are used to build helicopter PCBs to enable them withstand extreme temperatures.

Thermal compounds are also used in making helicopter PCBs to help in restricting heat from spreading to other parts of electronics.

Capable Of Absorbing Shock

Helicopter PCBs must be able to withstand the shocks and vibrations which are common in the aviation industry. To ensure that, there are alterations in PCB design such as pressing pins on the board instead of soldering them.

Pressing pins help in realising helicopter boards that are mechanically stronger than the soldered ones because the pins hold components more tightly. Both pins and soldering are used in some instances.

Able To Withstand Radiations

Helicopter PCBs, being exposed to high levels of radiations in the space, should be able to withstand them to avoid being damaged. The PCBs should be designed to be radiation tolerant.

Anti-fuse technology is normally employed to make the helicopter PCBs resistant to radiations.

Able To Withstand Varying Frequencies

Communication with helicopters is made possible through radio waves in the aviation industry.

The communication signals must be conveyed despite the environmental conditions.

The helicopter PCBs are designed to withstand varying frequencies that would corrupt the communication signals.

To achieve that, various strategic parts of the helicopter printed circuit board are shielded just the same way the antenna is shielded.

In addition, transmission lines can also be shortened to help in realising seamless transmission.

Rust Resistant

The exposed copper areas of the helicopter PCB is covered using coatings such as solder masking and aerosol coating.

Epoxy coatings can also be applied since they act as barriers to oxidation which can lead to rusting.

In addition, coating also helps in holding out to thermal demands that come as a result of high temperatures.

Conformity To Aerospace Regulations And Standards

Your helicopter PCB manufacturer must adhere to the established PCB manufacturing standards for the aviation industry.

The standards are grouped based on the particular parts of the PCB manufacturing process that are of priority.

Optimal Operation Of The Aerospace Systems

Corrosion resistance, selecting the right materials, and being able to withstand extreme temperatures all contribute towards optimizing the operations of the helicopter systems.

Durability, being able to withstand high frequencies and radiations also put the helicopter PCBs in a position to operate optimally.

Where Should You Use Rigid And Flexible Helicopter PCB?

Rigid helicopter PCBs, those that cannot be twisted or folded into other shapes, are used in the following parts of a helicopter:

  • To build auxiliary power units
  • In making airplane cockpit instrumentation
  • In manufacturing power converters
  • In making temperature sensors

Flexible helicopter PCBs, the ones that can be bent or twisted in other shapes, are used for connection applications in a helicopter.

How Are Flexible And Rigid-Flex Helicopter PCB Beneficial In Aerospace Industry?

Flexible PCBs have the advantage of being able to be bent to fit in narrow and oddly shaped spaces of the helicopter.

That quality makes it possible to use them to build smaller electronic products for helicopters.

They also have the benefit of high adaptability because a product does not have to be packaged to fit around PCB restrictions.

Additionally, they are more heat resistant if compared to the rigid PCBs.

A rigid-flex PCB has all its electronic interconnectivity buried within the board thus reducing the overall weight and size of the board.

They are the ideal choice in circumstances when ultra-light packaging is a priority.

In addition, rigid-flex helicopter PCBs have high reliability and durability while remaining strong and flexible at the same time.

How Does RF Helicopter PCB And High-Speed Helicopter PCB Compare?

RF helicopter PCBsHigh speed helicopter PCBs
The design of RF helicopter PCBs focuses on the signal frequency. RF helicopter PCBs are considered to be those operating in frequencies exceeding 100MHz.High-speed helicopter PCB design focuses more on the PCB’s physical characteristics that affect its signal integrity. Those are factors such as interconnections, packaging, layouts, and layer stack-up.

The high-speed designs are carried out with issues such as attenuation, cross-talk, emissions, delays, and reflections in mind.

RF helicopter PCBs are sensitive to noiseAlso get corrupted by noise
RF helicopter PCB requires tighter impedance tolerancesMust also have proper impedance to ensure higher signal quality and integrity.

What Is The Recommended Aspect Ratio In Helicopter PCB Design And Layout?

The recommended aspect ratio, the ratio between the bare boards compared to the vias as the latter is drilled, should be 1:10.

What Are The Rules That Must Be Adhered To In The Designing Of Helicopter PCBs?

The top must-knows that designers must keep in mind when designing helicopter PCBs include:

Reliability

Aerospace customers expect their electronics to last as long as 15 to 20 years.

Longevity and zero failure are therefore key in the design of the helicopter PCBs.

Designers are expected to use standard technologies that have been proven to be reliable and failure proof.

They should not go for options such as bleeding edge technology.

Use Of Heavy Copper

Copper as heavy as 4-oz or 5-oz should be used in the manufacture of helicopter PCBs to help in heat dissipation

Choosing A Standardized Process Manufacturer

As you pick a manufacturer for your PCB, be sure to settle for one that will ensure each process is repeatable and standardized.  The manufacturer must establish measurements and controls to guarantee that 100% repeatability will always be achieved.

Forget About RoHS

RoHS compliance is certainly never going to apply in producing helicopter PCBs because the aerospace industry is not likely to abandon the leaded HASL.

That is because the risk of moving to other surface finish, increased temperatures, or SMT could be too high for the PCB products.

Encapsulation

The helicopter PCBs have to be built such that they operate in an encapsulated and controlled environment.

That ensures that they are not exposed to any elements that could cause damage.

The PCBs should however be exposed to cold and heat cycling all the time to allow temperature control.

Testing

Lots of tests must be conducted on the helicopter PCBs before they are released for use to ensure that they do not fail.

Temperature tests, for instance, are conducted to ensure the PCB can withstand the widely ranging temperatures within which they are to be used.

Other kinds of tests that may be carried out on the helicopter PCB include:

  • X-ray inspection – this is more of an inspection tool used to locate defects along the helicopter PCB development stages. It entails viewing internal traces, solder connections, and other parts of the PCB.
  • Functional test – carried out to ensure the helicopter PCB will power up.
  • Burn-in testing – it is meant for detecting failures and establishing load capacity. This test should be performed with caution because it can easily damage the PCB parts due to its intensity.
  • In-circuit testing – the test involves powering up and actuating individual circuits of the helicopter PCB.
  • Flying probe testing – is a non-powered testing measure that involves checking of inductance, capacitance, resistance, shorts, opens, and diodes issues.
  • Automated Optical Inspection (AOI) – 2D or 3D cameras are used to take photos of the helicopter PCB.

Paperwork

Paperwork including minimum plating requirements, release requirements, quality requirements among others is very strict in the helicopter PCB manufacturing process.

Paperwork is emphasized to optimise quality control, micro-section analysis, testing, and reporting.

Paperwork is made strict just to ensure that the final PCB products are built exactly how they are needed.

It also ensures the PCBs meet the standards such as IPC 6012DS and many others.

Which Are The Different IPC-6012 Standard Class Specifications For Wrap Plating Of Helicopter PCB?

There are various class specifications with regard to the thickness of the electrolytic hole plating hole thickness.

The IPC-6012 standard has got class I, class II, and class III categories.

  • Class I – the thickness is agreed upon between the user and the supplier in this class of thicknesses specification.
  • Class II – the wrap plating is made continuous through the filled plated hole and then it is extended onto the surface of the helicopter PCB.
    The wrap plating thickness must not fall below 5μmfor both through-holes and via structures.
    Use of planarization, etching, and sanding processes to process the helicopter PCB should not lead to reduced wrap plating space in place.
    That should not happen even when the processes result in the reduced thickness of the copper material.
  • Class III –is essentially similar to class II save for the fact that the warp plating minimum thickness should not be anything below 12μm.
    The specification applies for blind vias, through-holes, and buried vias with more than two layers.
    In the same class too, the minimum thickness of buried vias core should be 7μm.
    Both buried microvias and blind on the other hand can have a minimum thickness of 6μm.

Can You Fabricate Helicopter PCB Prototype?

Yes, a helicopter PCB prototype can be fabricated.

What Are The Helicopter PCB Prototype Details You Should Send Your Manufacturer?

There are prototype specifications you have to give your designer to ensure the eventual quality production of your helicopter PCBs.

Such kind of information include:

Quality Grade Of The Prototype

The quality grade is most of the time Standard IPC 1 in majority of the prototypes.

Quality may vary though depending on what the customer wants.

The quality of the helicopter PCB prototype must meets the ISO standards and the standards set by regulatory bodies in various jurisdictions.

Number Of Layers

Helicopter PCB prototypes have varying number of layers depending on what the customer needs for a final product.

A helicopter PCB prototype can have a minimum of one layer or a maximum of eight.

Number Of Helicopter PCB Prototypes

The number of the helicopter PCB prototypes you need will depend on the size of work you would want to do. Quantity will also depend on the capability of your PCB manufacturer.

Various manufacturers have various capabilities depending on the machines they have.

Type Of Material

Helicopter PCBs can be made from various types of materials. The customer will select the material they need to be used in making their prototypes.

The material used must meet the set standards. It should be able to stand out to pressures of its environment of operation such as high temperatures.

Size Of The Helicopter PCB Board

Size of the board you wish to build is an important detail you must share with your designer. It is useful in planning for how wires will run through the prototype.

The designer might also choose to use more components depending on the size you have provided.

There are various size options to choose for your helicopter PCB from 6*6 millimetres minimum to 500*500 millimetres maximum.

The size of your helicopter PCB will be dependent on the part of the plane where it is to be used.

Copper Specification

Provide the copper specifications such as weight and tolerance of copper thickness you need for your prototype helicopter PCB.

What Is The Difference Between Positive Helicopter PCB Etchback And Negative Helicopter PCB Etchback?

Etchback is the process used in removing epoxy resin that forms along the sidewalls of vias due to PCB hole drilling.

There are two types of etchback processes referred to as positive etchback and negative etchback which differ in the following ways:

Positive EtchbackNegative Etchback
Positive etchback refers to the cleaning process where the dielectric material is cleaned back within the hole walls. That makes the copper land to protrude beyond the edges of the PTH.

 

For negative etchback process, cleaning of the holes is carried out such that copper land gets recessed from the edges of the walls.

 

Preferred in making helicopter PCBs to help in realising a strong three-terminal contact that guarantees performance and reliability.Negative etching process is not recommended for making helicopter PCBs.

How Do You Overcome The Impacts Of Extreme Shock And Vibrations On Helicopter PCB Components?

Techniques such as using pins to firmly hold components instead of usual soldering are used to cushion helicopter PCBs from shock and vibrations.

Leaving small spaces between the components and the board’s surface also helps in achieving the same purpose.

Which Are The Common Industry Standards That Helicopter PCB Should Comply With?

Electronics on helicopter cockpit

Electronics on helicopter cockpit

There are various national, regional, and international industry standards that have been established to regulate the production of helicopter PCBs.

The standards not only ensure that the PCBs are safe for use but that they also meet the desired performance and reliability levels.

Some of the of the common industry standards for building PCBs meant for aerospace applications include:

International Organization Of Standardization (ISO) Certification

ISO standards such as those existing in the ISO 9000 family provide guidelines and industry specifications for assembling helicopter PCBs.

The standards regulate quality management systems (QMS) and processes to ensure contract managers (CMs) uphold high quality and customer service standards.

UL Standards

UL mark from your manufacturer is an indication that your helicopter PCB has undergone and passed the required safety and flammability tests.

Institute For Interconnecting And Packaging Electronic Circuits (IPC) Standards

There are IPC standards for almost every stage of a helicopter PCB productions process.

There are several IPC standards for helicopter PCBs such as IPC-2581, IPC-2221, IPC-4101C, IPC-6012B, and many others.

IPC-4101C, for instance, provides specifications regarding the base materials mostly for use with rigid helicopter PCB boards.

International Electro technical Commission (IEC) Standards

The IEC has got standards such as IEC 61249-2-43:2016 that specify the materials to be used to make helicopter PCBs and related interconnects.

Federal Aviation Administration (FAA) Standards

FAA standards on avionics systems, including helicopter PCBs, set electronics, mechanical, and operator requirements that should be observed by product manufactures.

Your helicopter PCB must be able to withstand power fluctuations, manage temperature demands, and operate within steady-state tolerances to be eligible for FAA certification.

Of course, complying with Institute of Electrical and Electronics Engineers (IEEE) standards is also important.

How Do You Reduce Signal Attenuation In High-Speed Helicopter PCB?

Signal attenuation in high speed helicopter PCBs can be checked by using the following techniques:

  • Making Use Of Repeaters – a repeater can regenerate the original signal by reducing attenuation in a weak signal in a helicopter PCB.
  • Using Amplifiers – an amplifier can be used to increase the amplitude of a weak signal in a high-speed helicopter PCB.

Helicopter receiver PCB

Helicopter Receiver PCB

  • Right Selection Of Materials – signal attenuation can be mitigated by careful selection of low-loss dielectric materials and low resistance traces.
  • Using Programmable Differential Voltage Output Voltages (Vods) Settings – this guarantees that the drive strength synchronises with the line impedance and the trace length. An increased VOD at the driver results in an enhanced signal at the receiving end.
  • Pre-Emphasis – this technique strengthens only the high frequency components of a PCB signal by increasing the level of the first transmitted symbol.
    The technique does not boost noise and jitter like in amplification.
  • Receiver Equalization – here, an equalization circuitry attenuates the low frequency components of the signal upon reaching the receiver.
    That helps in recovering helicopter PCB signal losses experienced along the transmission lines.

What Are The Causes Of Signal Attenuation In Helicopter PCB?

Some of the factors that cause signal attenuation in helicopter PCBs include:

  • Noise Sources – noise due to electrical currents, RF frequencies, and leakage currents disturb signals leading to attenuation. The higher the noise the higher the attenuation.
  • Trace Width – helicopter PCB signals will get more attenuated if they travel through a narrow trace.
  • Cross Talk – signal attenuation in PCBs also result from crosstalk in nearby traces.
  • Conductors And Connectors – helicopter PCB signals also get attenuated as they pass through various conductor materials and connectors.
  • Copper Surface Roughness – rough copper surfaces offer resistance to signal flow in helicopter PCBs leading to attenuation.
  • Dielectric Material Losses – the dielectric materials used to make the helicopter PCBs introduce dielectric losses leading to signal attenuation.
  • Frequency Of Transmission – radio waves having short wavelengths suffer lots of attenuation.
  • Resistive Losses Due To The Conductive Material –conductive materials such as copper cause resistive related losses in the traces leading to weakening of signals.

What Is The Meaning Of Skin Effect In RF Helicopter PCB?

It refers to an occurrence in which higher frequency components begin to travel closer on the outside of a PCB conductor than within it.

How Does Helicopter PCB Fab Drawing Differ From The Assembly Drawing?

A fabrication drawing, often shortened as fab drawing, is meant to provide details of how a helicopter PCB should be manufactured.

The fab drawing specifies critical details such as drill chart, board outline, layer stack-up, and many more required to build a helicopter PCB.

Assembly drawing, in contrast, gives the details about how PCB components will be fixed on the helicopter PCB.

Assembly drawing thus forms the basis of mounting components and setting up automated placement of components.

What Information Should You Include In The Helicopter PCB Fab Drawing?

Some of the most important details that should not miss in a helicopter PCB fab drawing include:

Helicopter transmitter PCB

Helicopter transmitter PCB

  • Board Outline – it gives the pictorial representation of the helicopter PCB. The information in the board outline includes details such as holes, cut-outs, various radii, and distances that should be in the actual board.
  • Drill Chart – contains the symbols assigned to all the holes provided for in the board outline. The chart contains information pertaining to holes to be drilled in the helicopter PCB board to be manufactured.
  • Title Block – the title block of the fab drawing should include details such as part number, customer name, revisions, measurement units, and fabrication numbers specified.
  • Layer Stack-Up – this provides details such as material type, dielectric spacing, copper weight, layer order, and the total thickness of the stacking. The controlled impedance requirements may also be provided in the stack-up.

Other details that might be included in the fab drawing, though not must-have, include tolerances, plating details, surface finish, and others.

Why Is Thermal Profiling Important During Helicopter PCB Assembly?

The thermal profiling process of controlling temperature in an oven helps in firmly connecting components to the helicopter PCB board.

While your PCB is in the reflow oven, thermal profiling at regular intervals helps in providing authentic data useful in optimising the process.

Adjustments can also be made as may be necessary based on that data.

What Is The Standard Tolerance For Controlled Impedance In Helicopter PCBs?

The standard tolerance for controlled impedance for the helicopter PCB is +/- 10 ohms.

Helicopter PCB

Why Should You Use Heavy Copper In Helicopter PCB?

The natural properties of copper help in achieving cooling and heating requirements in the helicopter PCB.

How Much Does Helicopter PCB Construction Cost?

The cost of constructing a helicopter PCB is a function of factors such as the materials used, the components, and the board size.

Other factors that determine the cost of constructing helicopter PCBs include cost of labour and shipment costs.

So there is no fixed cost of constructing a helicopter PCB.

The cost is set by the manufacturer depending on the expenses due to the factors listed in the above paragraph.

In general though, it costs between $10 and $50 do produce a helicopter PCB.
