Frequently Asked Questions

Q: What types of screen faults can J9 Nano Conductive Silver Paste fix?

A: The J9 Nano Silver Paste is designed to repair yellow, green, and white screen faults caused by damaged ITO lines, broken flexible circuit traces, or micro-soldering failures on OLED, AMOLED, and LCD panels. It is also compatible with flexible PCBs and sensor circuits.

Q: How long does the J9 Nano Silver Paste take to cure?

A: After applying the paste to the damaged circuit line, heat-dry at 150°C for approximately 30 seconds. Once cured, you can verify the repair immediately using a multimeter to check conductivity across the repaired area.

Q: Is J9 Nano Silver Paste safe to use on sensitive mobile components?

A: Yes. The J9 paste is RoHS certified, meaning it is lead-free and non-corrosive. It is specifically formulated for use on sensitive electronics including OLED/AMOLED screens, flexible PCBs, and delicate sensor circuits without risking damage to surrounding components.

Q: How much paste is included and how many repairs can it complete?

A: Each syringe contains 0.8g of nano silver paste. Since application requires only 1–2mm diameter dots per repair point, a single syringe is sufficient for multiple circuit line repairs. A reusable storage container is included to preserve unused paste between sessions.
