Product Description
4 Layer High Temperature Resistant OSP PCB
High temperature resistant OSP black oil double panel PCB is a double-sided printed circuit board integrating high temperature resistant performance, OSP (Organic Solderability Preservative) surface treatment, and a black solder mask. It adopts a double-sided wiring design: the substrate is made of high temperature resistant materials (such as high Tg FR-4), and the surface is coated with black ink as the solder mask, which provides insulation, protects the circuit, and offers good light-shielding properties. Both sides of the board undergo OSP treatment on exposed copper surfaces, forming a thin organic protective film through chemical reactions to prevent copper oxidation while maintaining solderability. This PCB is suitable for circuits operating in high temperature environments (typically above 130℃) and adapts to the welding needs of conventional and precision components.
