Solder resist ink based on silicone resin. 【Features】 ■ Utilizes the properties of silicone resin for "high heat resistance" and "UV resistance" ■ "High heat resistance" = Almost no discoloration or reduction in reflectivity after reflow ■ "UV resistance" = Strong against ultraviolet light, with almost no degradation even under UV-C exposure ■ Although it is silicone resin, it has minimal outgassing, making it safe for use *For more details, please download the PDF or contact us.

We provide high heat-resistant printed circuit boards using Okitsumo's high heat-resistant solder resist ink "TAINEX Series" and FR-4 high heat-resistant grade materials. These boards have excellent heat resistance and can be used in high-temperature environments where standard printed circuit boards are difficult to employ. They are made from halogen-free materials and comply with various environmental regulations. Please feel free to contact us when you need assistance. 【Features】 ■ Continuous heating: 150℃ / 1000h - No swelling or peeling ■ Continuous heating: 175℃ / 1000h - No swelling or peeling ■ Temperature cycle (-65℃ ⇔ 150℃) × 3000 cycles achieved - No swelling or peeling ■ Made from halogen-free materials and compliant with various environmental regulations *For more details, please refer to the PDF document or feel free to contact us.
