The hot air achieves an even spread of the solder, providing a surface finish with matching thickness. Using HASL attracts the least cost allowing you to employ it in large-scale LED TV PCB manufacturing economically.

ENIG (Electroless Nickel Immersion Gold)

When using ENIG for your LED TV PCB, you apply a gold and nickel finish over your circuitry.

Here, you apply a nickel layer electrolytically before achieving a gold finish to protect the nickel surface from oxidation by immersion.

The ENIG finish allows you to retain the nickel’s surface’s solderability while offering you an extended life without rework.

While you find the process costly, you achieve an even surface that provides impressive solderability.

OSP (Organic Solderability Preservative)

With the OSP finish, you employ organic-based components in shielding the circuitry on an LED TV PCB from oxidation.

You clean the copper surface using chemical agents before applying the organic solder preservative via a conveyer approach.

The OSP finish succumbs to extreme humidity and temperature conditions and direct sunlight, which can cause breakage.

It is, however, one of the most environmentally safe methods as it employs no harmful elements.

ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold)

Achieve a triple-layer surface formation when employing an ENEPIG surface finish consisting of palladium, gold, and nickel surfaces.

Here, you first lay a nickel surface through an electroless process before similarly applying a palladium surface.

After applying the nickel and palladium surfaces, you add a gold surface via immersion, providing overall protection from oxidation.

While similar in properties to ENIG, palladium allows you to furnish a thinner gold coat, helping cut costs.

An LED TV PCB has a power supply board that can limit the load current to safe values.

Such situations arise from electrical faults, overvoltages, noise generation, temporary power interruptions, and power correction.

The power supply board can distribute power to various loads on an LED TV PCB from a single input connection.

Additionally, you find the power supply board integrated with the backlight inverter board, LED driver, and the T-con board.

LED Driver

An LED driver is a circuit formation that functions as a power supply in controlling the amount of power for LEDs.

LEDs produce light employing low energy to function over a long time, thus requiring a unique power supply.

The LED driver varies the power with the light emissions’ temperature, preventing overheating the LEDs that can cause damage.

Consequently, an LED driver offers you protection for the LEDs from inconsistent voltage and current and low voltage supply.

FRC Board

The frame rate control board allows you to achieve more in the depth of color for your LED display. With an FRC board, you have a color cycle that dithers between different shades for new frames for your television.

IR Sensor

An IR (Infrared) sensor on an LED TV PCB is a photodiode that can detect infrared radiation.

You note that the detected radiation has the same wavelength and originates from an emitter, usually a remote-controlled LED.

When the radiation lands on the diode, there’s a change in the resistance and output voltage proportional to the radiation’s magnitude.

The IR sensor thereafter outputs a response whose intensity determines that of the IR receiver.

Keypad Controller

A keypad controller is a circuit formation that scans the keypad’s matrix, interpreting switch movements and communicating keypad actions like presses.

The keypad controller has stored software providing the remote keypad’s functionality.

What Is The Difference Between An Internal And External LED Driver In LED TV PCB?

An LED driver determines the power supply to LEDs in your LED TV PCB, offering protection from overvoltage.

You can have LED drivers either external or internal to your LED array.

An internal LED driver shares the same assembly with the LEDs, whereas external drivers have spate assemblies.

What Factors Do You Consider When Selecting LED Drivers For Your LED TV PCB?

Selecting LED drivers for your LED TV PCB requires consideration of the following factors:

Mode Of Current And Voltage

With LED drivers, you find two possible modes: constant current mode or constant voltage mode.

LED drivers with continuous current mode only propagate a fixed current as output.

However, they can have several voltages as output.

On the other hand, LED drivers with constant voltage propagate a fixed voltage as output.

Additionally, the current production has a maximum regulated value finding use in applications requiring voltage stability.

Size

It is essential to consider the size of your LED drivers to ensure they fit in the area of application. A mismatch of your LED drivers and board location can be a costly affair.

Rating Of Ingress IP

The Ingress IP rating measures the casing’s environmental protection status considering moisture, dust, and other particles.

Accumulation of moisture or particulates o the LED drivers can result in performance failure.

Power Factor

LED drivers act as a power supply to LEDs, ensuring a low voltage input for the LEDs.

By using LED drivers, you prevent damage of LEDs from voltage and current spikes.

Maximum Wattage

Maximum wattage refers to the power limit the LED drivers can input for load supply to the LED array.

Exceeding the power limit is likely to damage the LED drivers who will cut off supply to the LEDs

What Infrared Sensors Can You Employ With Your LED TV PCB?

Infrared sensors detect or emit infrared radiation of similar wavelengths employing photodiode and LEDs, respectively.

You can classify infrared sensors as active or passive depending on the working principle.

Active IR Sensor

An active IR sensor encompasses both transmission and reception capabilities, with many employing an LED.

The sensor can be imaging or non-imaging, using a laser diode for the former and an LED for the latter.

When using active IR sensors, you communicate, transmit, receive and interpret using a radiation medium.

A signal processor allows you to decode the infrared radiation transmission into logical information for output.

Active IR Sensor

Active IR Sensor

Passive IR Sensor

A passive IR sensor lacks the transmission aspect, only possessing detection capability.

Using an IR source, you find these sensors employ receivers for infrared radiation with an energy release.

Passive IR sensors also have a signal processor that decodes the received signals for logical interpretation.

You can have passive IR sensors that are thermal or quantum with the former independent of wavelength.

Thermal IR sensors receive radiation signals from a heated energy source.

Additionally, you find the response time of these sensors is slow similar to the time they take for detection.

Contrarily, quantum IR sensors depend on the radiation’s wavelength, which possesses quick response times and detection ability.

Passive IR Sensor

Passive IR Sensor

Can You Interchange Parts Of Different LED TV PCBs?
