LED Display Circuit Paper / LED Module PCB Pad Repair Sheet / LED Display Pad Repair Paper Description

LED Display Circuit Paper — also known as the LED Module PCB Pad Repair Sheet or LED Display Pad Repair Paper — is a professional repair material used to restore damaged or missing solder pads on LED display modules. During maintenance, transportation, or repeated disassembly, the copper pad on the module PCB may lift or peel off, preventing proper soldering of the SMD LED. This pad repair sheet functions as a precise replacement pad, enabling technicians to quickly rebuild the solder point, restore electrical conductivity, and securely re-mount the LED lamp bead. With its ultra-thin profile and high-reliability surface finish, the repaired area remains flat, clean, and visually consistent with the original module. It is widely used by LED display maintenance engineers and service providers, and is suitable for both fine-pitch and standard LED modules, including but not limited to P1.25, P1.5, P1.8, P2.5, and similar pixel pitches.

Product Features:
• Ultra-Thin Design (0.08mm): Precision thin profile keeps the repaired area perfectly flat and flush with the original PCB surface, preserving module uniformity.
• ENIG Surface Finish (Gold Dipping Process): Immersion gold plating offers excellent oxidation resistance and superior solderability for stable, long-lasting electrical connections.
• Arbitrary Cropping: The repair sheet can be freely cut into different sizes and shapes to match various pad layouts, enabling fast and flexible on-site repairs.
• Large Pad Area: Enlarged pad design improves soldering tolerance and reliability, making LED rework easier and reducing the risk of cold joints.
• Double-Sided Matte Black Coating: Provides a uniform black appearance with high contrast, ensuring the repaired module maintains a professional visual finish.
• Durable & Safe: Optimized line width and spacing support higher current flow while minimizing the risk of overheating or short circuits.
• Factory Direct Supply: Produced by the original manufacturer for consistent quality and competitive pricing.
• Custom Pitch Available: Supports customization for non-standard pixel pitches and special pad layouts, with no design fee required.

Industry Terminology:
• Horizontal Lamp: When viewed from the front, the LED pins are arranged horizontally:
R (Red) – top-right
G (Green) – top-left
B (Blue) – bottom-left
+ (Positive 5V) – bottom-right
This configuration is widely used in indoor fine-pitch LED modules.
• Vertical Lamp: When viewed from the front, the LED pins are arranged vertically: R, G, B stacked vertically, with the + (Positive 5V) terminal positioned on the side. Choose the corresponding vertical repair pad type for this configuration.
• Universal Type: A dual-compatible design suitable for both horizontal and vertical LED orientations—ideal for modules with mixed or uncertain lamp directions.
• 4-in-1 SMD LED: The 4-in-1 SMD LED is a packaging method where four SMD chips are integrated into one large LED package. Each package contains four pins — R, G, B, and a shared positive (+) terminal.
• 4-pin SMD LED: For a single SMD LED, the three colors (R, G, B) are independently driven but share a common DC positive supply. This is the standard structure used in most full-color SMD LED displays.
• 6-pin SMD LED: In a 6-pin SMD LED, each color channel (R, G, B) has its own pair of positive and negative pins. This design offers higher electrical stability, better heat dissipation, and improved driving performance, making it ideal for high-brightness or high-reliability LED display modules.

Summary:
The LED Display Circuit Paper is a professional-grade, ultra-thin repair solution for restoring damaged or peeled PCB pads on LED display modules. With its ENIG surface finish, excellent conductivity, and easy operation, it ensures long-term performance and reduced maintenance costs. Perfect for LED technicians, service centers, and factory repair departments handling SMD LED pad rework or PCB restoration.
