PCB Circuit Board Industrial Papers<\/strong><\/p>\n\n\n\n

In the full PCB circuit board production process, beyond the core sulfur-free paper, other specialty industrial papers are used across five major stages: process manufacturing, surface treatment, lamination & encapsulation, cleaning & wiping, and packaging & transport.<\/p>\n\n\n\n

1. LED Sulfur-Free Paper<\/strong> Prevents silver paste, brackets, and silver-plated layers from sulfurization and blackening. The most essential core paper for LED manufacturing.<\/p>\n\n\n\n

2. Electroplating Sulfur-Free Paper<\/strong> Also known as: Sulfur-Free Isolation Paper, Silver Plating Sulfur-Free Paper, Hardware Terminal Sulfur-Free Paper<\/p>\n\n\n\n

Core Specs: Sulfur content \u226450ppm (premium grade \u22645ppm), chlorine-free and halogen-free<\/p>\n\n\n\n

Core Uses: Isolates silver-plated, gold-plated, and tin-plated hardware from sulfurization, preventing discoloration, blackening, and poor contact; suitable for terminals, connectors, and precision stamped hardware during in-process transfer and stacking storage<\/p>\n\n\n\n

Special Grades: Anti-static sulfur-free paper (surface resistance 10\u2077\u201310\u2079\u03a9), dust-free sulfur-free paper (Class 100), for high-precision electronic hardware<\/p>\n\n\n\n

3. Glass Sulfur-Free Paper<\/strong> Also known as: Coated Glass Sulfur-Free Isolation Paper, Optical Glass Sulfur-Free Paper<\/p>\n\n\n\n

Core Specs: Sulfur content \u226420ppm (premium grade \u22645ppm), chlorine-free and halogen-free, dust-free grade<\/p>\n\n\n\n

Core Uses: Isolates silver-plated, gold-plated, and ITO conductive glass, preventing sulfur from reacting with coating layers causing discoloration and film peeling; suitable for display panels, touch glass, and coated glass during in-process transfer<\/p>\n\n\n\n
