What is the assembling process of an LED TV?

What had been just a simple mode of relaxation has now become a mere mode of necessity. Apart from being the best source of entertainment, television speaks the language of recent technology. And anyone who makes a move to buy a TV always approaches to buy the best one from the market. These smart TVs are the television where one can use it in different ways. From using social media platforms to playing video games, an LED TV is more than just a mode of entertainment.

The assembling process of an LED TV

Despite the popularity of LED TV, manufacturers encounter some pressures driving down the costs. The manufacturers are continuously turning to higher volume automated producing apart from high-speed inspection for improving the quality of the products. There’s no denying that the market of these televisions is pretty huge and their applications are present in multiple forms.

An LED TV production line and an assembly line can be either made automatic or manual depending upon the budget and volumes. Manufacturing the primary LED products include the probing-sorting of the chips, wire bonding, die bonding, encapsulation, phosphor coating, auto-testing, partial singulation, binning-testing, waffle packing or tape-n-reel. Contrarily, handling LED in the mounting processes becomes challenging. However, the nozzle design and customization is concurrently essential. The primary LED assembly line has been divided into three steps. While the first and second ones are screen printing and SMT component mounting with the help of pick and place, the third one is reflowing. Mentioned below are the brief introductions to the three steps.

Three steps of the assembling process of an LED TV

Manual screen printer – All the manufacturers will be able to get stencil which is designed for the solder paste printing on PCB pads. This stencil is led in the manual printer. The bare board PCB, then, is kept right below the stencil. Right above the stencil, the solder paste is then applied. The operator makes the best use of a tool for pasting solder above the stencil. Upon then, the PCB pads are printed alongside the solder.

Pick and place machine – This step mounts the LED on the PCB. As a matter of fact, the LED comes in its real form, and this is feeded with the feeder. Talking about feeder, it is an accessory for the purpose of pick and place. Upon then, the feeder gets loaded on the machine. The feeder gets loaded on the machines. Upon then, the program is set as per the coordinates, for example, the Y-axis, X-axis, head no., and angle apart from other coordinates. As a matter of fact, the machine head will pick LED automatically from the feeder. Upon this, it would place them on the given coordinates. This goes hand in hand with the assembling process of an LED TV.

Reflowing – Machines now proceed with the soldering. As far as the solder paste melting point, the healing profile gets generated in the reflowing oven and then eventually melts the solder paste. Upon then, the cooler dries the solder paste, and the LED legs get a permanent fix on the pads.

The Process of the LED assembly

  • Dispensing of the adhesives
  • Dispensing of the conductive glue
  • Curing or soldering of the LED connections
  • LED placement on the PCB and foils
  • Machines to produce the LED light fittings
  • Manufacturing keyboards with keys and LEDs
  • Lathe machine for matching the metal parts
  • The injection molding machine for molding the metal and plastic parts
