HDMI stands for High-definition Multimedia Interface.

They were introduced to replace three audio and video connectors in digital electronic devices.

They provide an interface with HD signals for both audio and video.

In PCBs, they are used to send highly rated signals from one port of a device to another.

In electronic devices, HDMI PCBs are used in their construction to better the functionality of the devices.

HDMI PCBs are most used in both commercial and domestic sectors to improve the connectivity of one device to another.

HDMI PCBs help to transmit, enhanced, high quality and standard video signals by offering up to 6 channels for digital data transfer.



How Does HDMI PCB Compare To USB PCB?

USB PCB is an HDMI alternative for HDMI-enabled with a USB-C connector that connects directly with HDMI standard PCBs.



This alternative model allows USB – C to carry three HDMI TMDS channels and the clock signal.



What Are The Components Of HDMI PCB?

Some of the main components are:

  • Consumer electronic control
  • Transition-minimized differential signaling
  • Display data channel
  • Audio Return Channel
  • HDMI Ethernet Channel
  • Connectors
  • Cables
  • Extenders

How Does HDMI PCB Work?

HDMI work using a transition minimized differential signaling (TMDS) technology to transmit data from one device to another.

The TMDS protects information from degradation during transmission.

Data is encoded by reducing the number of transitions.

This controls the chances of degradation while maintaining the quality of the transmitted signal.

How Do You Fabricate HDMI PCB?

This is the process of transforming PCB design into a physical device.

The process must maintain all the specifications of the design in the design files.

Process the substrate material: This is done through the saturation process for fiberglass.

The fiberglass is then passed between rollers to give it the needed thickness and remove any excess material deposits.

Shape the processed substrate: A thin layer of fiberglass is passed in an oven to strengthen it.

The fiberglass is cut into the desired shape and size.

Arrangement of other sized panel layers: Layering the panels to one another with a copper foil.

The copper foil is adhesive.

The stacks are pressed at 1500 psi pressure and a 340 Fahrenheit temperature.

Drill holes on the stacked PCB: Placing of holes on the panel is done using a numerically controlled machine at the designed positions as detailed during the design phase.

The holes are then plated by coating the inner surface of the holes with copper to make them conductive and non-conductive holes with non-conductive material.

Print the desired circuit pattern on the panel: Either the substrate method or the additive method is used.

For the additive method, you coat copper on the panel surface according to the desired diagram leaving the other areas uncoated.

The substrate method coats the whole PCB before removing the coating on unrequired areas leaving the designed circuit diagram.

Shield the circuit board using photoresist material: Photo resistive materials are pressed on the PCB.

This is done in a vacuum chamber using UV rays.

Spray alkyne: After removing the mask, spraying alkyne melts away distorted photoresistors and exposes the copper foil.

Oxidation prevention: The exposed layer on the panel is coated with copper foil of about 1 microinch.

A tin-lead coating is then applied to prevent oxidation of the copper layer.

Board completion and preparation of mountings: Tin-lead, nickel, and gold are used to plate the contact fingers.

To prevent damages from occurring on the panel during installation, epoxy resin is used to seal it.

With the panels cut into designed sizes, the PCB is ready for mounting.

Mounting components. Electronic components such as resistors are mounted on the panel to activate it.

The design of each PCB is different from the other and uses different electronic components.

Removal of remaining flux. Water and some chemicals are used to remove any remaining photo resistive flux.

The chemicals are chosen depending on the type of solder used.

Shipping: done only with bubble wrap or foam packaging to prevent them from miscellaneous damages.

Inspection of errors: Error inspection is important for quality control purposes.

This inspection helps to identify such errors so that they can be solved appropriately.

Surface finishes contribute to the determination of quality, cost, ability to be manufactured, and the reliability of the PCB produced.

Different surface finishes can be used on HDMI PCBs;

Hot air solder leveling involves a submersion of the PCB in a melted pot of a lead or tin alloy.

You then remove the extra solder by blowing hot air across the surface of the board.

Electroless Nickel Immersion Gold – This is the most popular finish for PCBs.

It is made of two layers of metallic coating.

Nickel is used to protecting copper while Gold protects Nickel from abrasion.

Organic Solderability Preservative You can apply anti-tarnish which will protect the copper surface from rusting.

Immersion Tin – Tin has metallic deposits which will prevent the underlying copper from rusting.

Tin also improves the PCBs shelf life.

How Do You Assemble HDMI PCBs?

HDMI PCBs are assembled through different methods.

Surface Mount Technology (SMT) PCB Assembly:

The SMT assembly is done in four main phases.

PCB organization: solder paste is spread on the required parts of the PCB.

Component insertion: components are inserted in their respective positions on the PCB using a pick and place device.

Reflowing of the soldiers: the PCB is heated in the SMD.

This heating process happens in a reflow oven at specific temperatures needed for solder paste to form solder joints.

Inspection: this is done through the SMT process using the assembler.

At times, you can also use through hole assembly depending on the type of component.

What Are HDMI PCB Connectors?

What Causes HDMI PCB To Overheat?

Overheating in circuit boards is caused by dirty environments that prevent air circulation and cooling.

Wrong circuit design, wrong placement of components, extreme environmental temperature, changes in the environmental temperature, and short circuits also result in overheating.

What Causes HDMI PCB Failure?

The short circuit of the circuit board; is majorly caused by improper solder pad design.

It can also be caused by inappropriate part direction.

The PCB joint turning golden yellow; high temperatures cause the PCB solders to turn from silver-gray to golden yellow.

Dark and granular contacts on the board; caused by contaminants and excessive oxides in the tin which make the joint structure brittle.

Loose and misaligned PCB components; reflowing the solder may at times cause small parts to float on the molten solder.

This may make them move out of the target joint resulting in tilting.

Tilting is caused by insufficient board support, reflow oven setting, solder past problems, and human errors.

Open circuit board; caused by the trace breaks.

In open circuits, the components are not soldered well on the PCB.

Welding problems; such as disturbed solder joints, cold welding, and solder bridge. 

Disturbed solder joints; occur when the solder joint is disturbed before the solder solidifies.

Cold welding; happens when the solder does not melt well resulting in rough surfaces and unreliable connections.

They can also occur due to excessive soldering preventing it from completely melting.

A solder bridge; happens when the solder crosses and physically connects two leads.

They create undersigned connections and short circuits resulting in burning out of circuit components when the current is high.

Environmental Reasons Related To The PCB Structure.

When the environment is not favorable to the PCB design, the PCB will fail due to circuit damage.

Extreme temperatures and changes, humidity, and high-intensity vibrations reduce the performance of the PCB or even be scrapped.

These changes destroy the solder joints, breaking copper traces and change the shape of the PCB.

Excessive moisture in the environment causes oxidation, corrosion, and rust on the PCB.

Dirty areas restrict airflow and cooling of PCB components resulting in overheating and degradation of the PCB performance.

Human error such as wrong production process followed incorrect placement of components, and unprofessional manufacturing specifications result in product defects.

Is There Maximum Working Temperature For HDMI PCB?

The maximum working temperature for PCB is 150 degrees Celsius.

Some PCBs can work beyond that but the circuit board with less heat resistance will not operate effectively at such temperatures.
