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: A colocação de furos no painel é feita usando uma máquina controlada numericamente nas posições projetadas conforme detalhado durante a fase de projeto.
Os orifícios são então revestidos por revestimento da superfície interna dos orifícios com cobre para torná-los orifícios condutores e não condutores com material não condutor.
Print the desired circuit pattern on the panel: Either the substrate method or the additive method is used.
Para o método aditivo, você cobre a superfície do painel de cobre de acordo com o diagrama desejado deixando as outras áreas sem revestimento.
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.
Um revestimento de estanho-chumbo é então aplicado para evitar a oxidação da camada de cobre.
Board completion and preparation of mountings: Tin-lead, nickel, and gold are used to plate the contact fingers.
Para evitar danos no painel durante a instalação, é utilizada resina epóxi para selar o mesmo.
Com os painéis cortados em tamanhos projetados, o PCB está pronto para montagem.
Componentes de montagem. 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. Água e alguns produtos químicos são usados para remover qualquer fluxo fotorresistente restante.
Os produtos químicos são escolhidos dependendo do tipo de solda utilizada.
Remessa: done only with bubble wrap or foam packaging to prevent them from miscellaneous damages.

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; ocorrem quando a junta de solda é perturbada antes que a solda solidifique.
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.
Erro humano such as wrong production process followed incorrect placement of components, and unprofessional manufacturing specifications result in product defects.
