The SONGZHI Applicator Blade is a precision tool specifically designed for the controlled application of liquid conductive silver paste used in ITO (Indium Tin Oxide) film repair and LCD screen line restoration.

When fixing yellow, green, or white vertical lines on iPhone, Samsung, or other smartphone screens, applying the correct amount of paste is critical. This fine-tipped blade allows technicians to spread micro-thin layers of paste evenly over exposed circuit traces, ensuring the conductive silver fills microscopic cracks without bridging adjacent circuits.

Key Features

• Ultra-Fine Flat Tip Design: Designed specifically to spread high-viscosity conductive silver paste in a thin, even layer over the exposed conductive tracks on flex cables.
• Scraper Function: Dual-purpose design often features a flat edge used to scrape away excess cured conductive paste after the heat curing process, preventing short circuits.
• Ergonomic Metal Handle (Typically): Provides a firm, balanced grip for precise control under a microscope, reducing hand fatigue during extended repair sessions.
• High Hardness & Reusability: Constructed from durable materials (often stainless steel or hardened plastic) that resists bending, wear, and corrosion from chemical solvents.
• Compatibility: Specifically designed for use with SONGZHI brand conductive paste but generally compatible with other nano-silver pastes (Wylie, YCS) used for screen rework.
