Precision FPC Micro Spot Welder Micro Welding Head For Sensitive Substrates

Precision Micro-Pressure Welding Head for Sensitive Substrates and FPC

The MF280RS Micro-Pressure Welding Head is a compact, high-accuracy spot welding module specially engineered to handle delicate welding scenarios where low force and stable pressure are critical. Designed for thin plating layers, heat-sensitive substrates, and flexible printed circuit (FPC) assemblies, the MF280RS delivers consistent micro-pressure control for demanding electronic manufacturing environments.With a finely adjustable pressure range of 40g to 1000g and a remarkable 1g resolution, this welding head ensures precise force application to prevent surface damage or delamination of thin metal coatings and sensitive circuit layers. Its real-time pressure monitoring and automatic alarm function guarantee that every weld point meets strict process parameters.

Competitive Advantages

• Ultra-Precise Micro-Pressure Control: Adjustable from 40g to 1000g with fine 1g steps.
• Stable Welding Force: High control accuracy up to ±2%FS minimizes pressure variation.
