👉 Bit fluid, often referred to as bit oil or bit grease, is a specialized lubricant used in electronic devices, particularly in printed circuit boards (PCBs). It's designed to fill microscopic gaps and crevices between components, ensuring a stable and reliable electrical connection while also providing excellent thermal conductivity. This fluid helps dissipate heat generated by the components, preventing overheating and extending the lifespan of the device. Bit fluid is typically non-conductive, making it safe for use in sensitive electronic circuits, and it's often applied during the manufacturing process to ensure optimal performance and durability.
