To be able to mount components delivered on either reels, in sticks or trays you need different component feeders to do so.

Below you see the different feeder types and the feeder cart that is available for the YSM20 and YRM20 pick and place machines.

SMT Feeder, (also called SMT Feeding Gun, Component Feeder, or Part Feeder), is an electric device to lock tape-and-reel SMD components, peel off the tape (film) cover on the top of components, and feeds the uncovered components (by means of sprocket transmission) to the same fixed pickup position for pick up by pick-and-place machine.

The SMT feeder is a crucial component of SMT machines, significantly impacting PCB assembly capabilities and production efficiency.

Components are typically supplied on paper or plastic tape, loaded onto feeders attached to the machine. While larger integrated circuits (ICs) can be arranged in trays stacked in a compartment, most ICs are supplied on tape, which is becoming the preferred format due to advancements in feeder technology. This method enhances the efficiency of part presentation on SMT machines.

4 Main SMT Feeders

SMT machines are programmed to pick up components from feeders and transport them to designated locations based on specific coordinates. Since different mounted components utilize various packaging types, each packaging format requires a corresponding feeder. The main categories of SMT feeders include tape feeders, tray feeders, vibratory/stick feeders, and tube feeders.

Tape Feeder

The tape feeder is the most common standard feeder in placement machines. Traditionally, it featured four structures: wheel, claw, pneumatic, and multi-distance electric. Modern advancements have led to the evolution of high-precision electric tape feeders, which offer greater transmission accuracy, faster feeding speeds, a more compact design, enhanced stability, and significantly improved production efficiency compared to traditional models.

Tray Feeder

Tray feeders can be categorized as single-layer or multi-layer structures. A single-layer tray feeder is directly mounted on the placement machine's feeder rack, occupying several slots but suitable for limited material types. In contrast, multi-layer tray feeders feature automatic transmission systems, taking up less space with a compact design. They are ideal for various IC components, including TQFP, PQFP, BGA, TSOP, and SSOPs.

Vibratory/Stick Feeder

Stick feeders are bulk feeders that load components into plastic boxes or bags through a vibrating feeder or feed pipe. This method is commonly used for MELF and small semiconductor components and is suitable only for non-polar rectangular and cylindrical components, excluding polar types.

Tube Feeder

Tube feeders often utilize vibration feeders to ensure that components continuously enter the chip head for placement. This method is typically used for PLCC and SOIC components, providing a protective effect on component pins. However, tube feeders may exhibit poor stability and reliability, which can affect overall production efficiency.

What Is the Function of the Feeder in SMT Placement Machines?

The feeder is a crucial component of SMT (surface mount technology) placement machines, responsible for holding and supplying small electronic components for placement on printed circuit boards (PCBs). Its primary function is to ensure that the placement machine can quickly and accurately position components on the board, optimizing the manufacturing process.

Feeder technology is vital for the precise placement of components on the PCB. Modern SMT machines can accurately place tiny components at high speeds, with feeders designed to store components in various formats, such as tapes, trays, and tubes.

The feeder works in conjunction with the placement head, which uses a vacuum nozzle to pick up components and place them on the PCB. It automatically dispenses components in the correct orientation, ensuring precise positioning for soldering.

Automation in the electronic assembly process significantly enhances efficiency and reduces production time, making placement machines essential to manufacturing. Feeders streamline the electronic placement process while minimizing errors.

In conclusion, the feeder plays a vital role in SMT placement machines, collaborating with the placement head to automate the component placement process. It enhances assembly efficiency by providing accurate and rapid placement of electronic components, ultimately improving the quality of the finished products.
