First of all, what is the SMT feeder? SMT feeder is also called SMT Mounter Feeder / SMT Machine Feeder / SMT Feeding Gun. Feeder is the most important part of SMT machine and  also an important part of SMT that affects the mounting capacity and production efficiency. Some SMT machines directly use the number of loadable feeders as a sign.
What are the types of SMT feeder? SMT machine is to pick up the components in the feeder through command to a specified location. Because different kinds of mount components adopt different packaging, different packaging requires corresponding feeder. The following is the main SMT feeder in the market.
According to the ways of feeding, the common ones are
  1. Tray feeder
It can be divided into single-layer and multi-layer. The single-layer tray feeder is directly installed on the feeder rack of SMT machine, occupying multiple grooves, which is suitable for the situation where there is not much tray material. The multi-layer tray feeder has automatic transfer multi-layer tray, taking up small space and compact structure, which is suitable for the situation where there are more tray materials. The tray mount components are mostly various IC integrated circuit components.
When using tray materials, it is necessary to keep the exposed components of large pipe corners to prevent damage to mechanical and electrical properties during transportation and use. When TQFP, PQFP, BGA, TSOP and SSOPs are used in the tray, the tray size can reach 150 mm * 330.2 mm, and the height can reach 25.4 mm. Interestingly, tray feeder can not only be used to pick up SMT components, but also be used as potential dumping station for valuable components.
2.Tape feeder
The tape feeder is the most commonly used standard feeder in SMT feeder. The traditional structure types include wheel type, claw type, pneumatic type and multi-space electric type. Now it has developed into the high-precision electric type. Compared with the traditional structure types, the high-precision electric type has higher transmission accuracy, faster feeding speed, more compact structure, more stable performance and greatly improved production efficiency.
The basic width of the tape material is 8mm, 12mm, 16mm, 24mm, 32mm, 44mm and 52mm. The spacing is 2mm, 4mm, 8mm, 12mm and 16mm,etc. The diameter of the reel is 7 in and 13 in.
3.Stick Feeder
The working mode of stick Feeder is to put components and parts into plastic box or bag freely, and send components and parts to SMT machine in turn by using stick feeder or feeding tube. This mode is usually used for MELF and small shape semi guide components and only applicable to non-polar rectangular and cylindrical components, but not polar components. Features: stick feeder is more expensive.
4.Tube feeder
The tube feeder usually uses vibration feeder to ensure that the components in the tube continuously enter into the picking position of the tip. Generally, PLCC and SOIC use this way to feed. The tube feeder has the characteristics of good pin protection, poor stability and standardization, and low production efficiency.
