SMT Feeders

About SMT Feeders

An SMT pick and place machine feeder is a precision electromechanical device that stores, peels, and presents surface mount components (resistors, ICs) in tape, tray, or tube format to a precise pickup position for a vacuum nozzle. They ensure high-speed, accurate component supply (e.g., within 

 mm), crucial for high-yield PCB assembly and overall line stability. 

• [Tape Feeders (Most Common): These hold components on paper or plastic tape reels. They automatically peel off the protective top film to expose the component. Modern feeders are predominantly high-precision electric (servo-driven) for faster, more accurate, and stable feeding, replacing older mechanical or pneumatic types. Common widths are 8mm, 12mm, 16mm, and 24mm.
• [Tray Feeders (Waffle Trays): Designed for larger or delicate ICs (BGA, QFP, SOP) that cannot be taped. They can be single-layer or multi-layer with automatic, high-precision tray transmission.
• [Stick/Tube Feeders: These feed components, such as SOTs or PLCCs, from tubes using vibration or gravity to move them to the pickup point.
• [Bulk Feeders (Vibratory): These use vibrating plates to orient loose components. They are cheaper but less precise and mostly used for simple, non-polar components
