What equipment and technologies are required for an LED display factory to achieve full in-house production?

To achieve full in-house production (vertical integration), an LED display factory needs equipment and technology across five core sectors:

Sector 1: SMT (Surface Mount Technology) Workshop

• Equipment:

  • Solder Paste Printer: Applies solder paste onto the PCB.

  • High-speed Pick & Place Machines: The core asset for precisely placing LED chips (SMD/COB) and ICs.

  • Reflow Oven: Melts the solder to fix components.

  • SPI & AOI (Automated Optical Inspection): Inspects solder paste volume and welding quality.

• Technology: Precision placement, reflow temperature profiling, ESD protection.

Sector 2: Plug-in & Wave Soldering (For DIP/Traditional modules)

• Equipment: Wave Soldering Machine, Auto Insertion Machine.

• Technology: Lead forming, flux control.

Sector 3: Module Assembly & Testing

• Equipment:

  • Glue Dispensing & Curing Lines: For waterproofing (outdoor screens).

  • Aging Racks: Power-on testing for 72+ hours to detect dead pixels.

  • Optical Testers: Measures brightness (nits), color temperature, and viewing angles.

• Technology: Waterproof sealing, pixel calibration (color correction).

Sector 4: Cabinet Manufacturing & Integration (Sheet Metal/Die-casting)

• Equipment:

  • CNC Machining Centers: Crucial for machining high-precision holes and splicing surfaces (especially for your mentioned 2.356m enclosures).

  • Laser Cutting Machine: For cutting metal sheets.

  • Press Brake: For bending cabinet edges.

  • Spray Painting Line: For surface powder coating or painting.

  • Assembly Lines: Installing power supplies, receiving cards, and masks.

• Technology: Sheet Metal Fabrication, Die-casting Mold Technology, flatness control, seamless splicing adjustment.

Sector 5: R&D and Quality Control

• Equipment: Temperature & Humidity Chamber, Vibration Table, Salt Spray Tester.

• Technology: PCB Layout design, Structural Design (SolidWorks/Pro-E), thermal simulation, driver IC solution development.
