What is
SMT Feeder classification|SMT feeder brand|SMT TechnologyWhat is SMT feeder? SMT feeder is the most important Accessories, but also the placement technology in the impact of placement capacity and production efficiency of the important components, some SMT placement machine can be directly equipped with the number of feeder as a sign.What are the types of SMT mounter feeders?SMT placement machine is through the instructions to the designated location to pick up the components of the feeder, due to different types of placement components using different packaging, different packaging requires the corresponding feeder. The following is the mainstream on the market SMT stickers p feeder.According to the feeding method:1. Tray FeederSMT FEEDER can be divided into single-layer structure and multi-layer structure, single-layer tray feeder is installed directly on the placement machine feeder rack, take up a number of bits, suitable for the tray is not much material; The material has a multi-layer automatic transmission tray, occupies a small space, compact structure, suitable for the situation of the tray material, disk components for a variety of IC integrated circuit components.When using the pallet material, care should be taken to keep the large corners exposed to the components in order to prevent damage to the mechanical and electrical properties during transport and use. When using the TQFP.PQFP.BGA.TSOP and SSOPs components in the pallet, Size can reach 150mm x 330.2mm, height 25.4mm. Interestingly, the tray feeder can not only supply the placement machine pick up components, but also can be used as a valuable component of the potential throwing station.2.Tape FeederBelt feeder is the most commonly used standard feeder in the placement machine. The traditional structure has the wheel type, the claw type, the pneumatic type and the multi-distance electric type. Now it has developed into high precision electric type, high precision electric Compared with the traditional structure, the transmission accuracy is higher, the feeding speed is faster, the structure is more compact, the performance is more stable, and the production efficiency is greatly improved.The basic width of the strip material is: 8mm.12mm.16mm.24mm.32mm.44mm and 52mm and other types, spacing 2mm.4mm.8mm.12mm and 16; reel diameter 7 in and 13 in two The3. Stick FeederBulk-type feeder, also known as vibration-type feed material, the work of the unit is free to load into the molding of plastic boxes or bags, by using a vibrating feeder or feed pipe to the components in turn into Mounter, this method is usually used in MELF and small form factor semiconductor components, only for non-polar rectangular and cylindrical components, not suitable for polar components. Features: vibration fly more expensive.4.Tube FeederTubular feeders often use vibration feeders to ensure that the components in the tube continue to enter the chip head to absorb the position, the general PLCC and SOIC is used in this way to feed the tube feeder has a protective effect on the component pin , Stability and normality is poor, the production efficiency of the end of the characteristics.5.Vibration Feeder special style, it need to be customized.

SMT Feeder (also known as Tape Feeder, SMD Feeder, Component Feeder, or SMT Feeding Gun) is an electric device that locks tape-and-reel SMD components, peels off the tape (film) cover on the top of components, and feeds the uncovered components to the same fixed pickup position for pick-and-place machine pick-up.
The SMT feeder is the most important component of an SMT machine, as well as an important component of SMT assembly that influences PCB assembly capabilities and production efficiency.
The majority of the components are supplied on paper or plastic tape in tape reels that are loaded onto machine-mounted feeders. Larger integrated circuits (ICs) are occasionally supplied in trays that are stacked in a compartment. Tapes, rather than trays or sticks, are more commonly used to deliver integrated circuits. Because of advancements in feeder technology, tape format is quickly becoming the preferred method of presenting parts on an SMT machine.
