Mechanic SU7 Blue High-Viscosity UV Curing Solder Mask Ink (10cc Syringe) – Rapid Hardening PCB Insulating Oil for Phone Repair

Overview 

The Mechanic SU7 Blue is a premium, high-viscosity light-curing UV solder mask gel engineered specifically for micro-soldering, flying jumper wire fixation, and precision PCB trace restoration. Unlike thin liquid solder mask inks that spill across adjacent components, the SU7 thixotropic gel stays exactly where placed under a microscope. Its distinct, high-contrast blue color provides maximum visual clarity, allowing technicians to easily track custom wire paths, verify pad isolation, and lock micro-jumper connections in place under ultraviolet light.

Key Features 

• High-Viscosity Gel Formula: Holds its shape without slumping, running, or bleeding onto neighboring IC pads, enabling pinpoint micro-dot placement.

• Rapid Multi-Layer UV Curing: Hardens in 3 to 10 seconds under a high-power 395nm UV lamp, creating a rock-hard dielectric barrier without a sticky sub-surface layer.

• High-Contrast Blue Finish: Bright blue pigment makes custom jumper wiring and repaired board sections instantly visible and traceable under microscope optics.

• Superior High-Voltage Insulation: Protects fragile micro-traces from high-voltage leakage, parasitic interference, and short circuits across high-density logic boards.

• High Heat & Reflow Resistance: Withstands high temperatures from hot-air rework stations and soldering iron tips without peeling, cracking, or lifting.

Technical Specifications 

Common Applications 

• Anchoring 0.01mm and 0.02mm ultra-fine enameled copper jumper wires on mobile motherboards

• Isolating custom wire runs from ground planes and nearby BGA chip pads

• Rebuilding broken or missing BGA pads and insulating underneath IC chips

• Color-coding specialized or custom logic board wire jumps during complex repairs
