What are the types of SMT surface mounter feeders?
1. Belt feeder
Belt feeder is commonly used in the mounter feeder kind of standard feeder, the traditional structure of the wheel, claw, pneumatic and multi-pitch electric type, has now developed into a high-precision electric type. High-precision electric type and the traditional structure relative to the way, transmission accuracy is higher, faster feeding speed, more compact structure, more stable performance, greatly improving production efficiency.
The basic width of the tape material has: 8mm, 12mm, 16mm, 24mm, 32mm, 44mm and 52mm and other types, the pitch of 2mm, 4mm, 8mm, 12mm and 16, etc.; reel diameter size of 7 in and 13 in two kinds.
2. Tray feeder, disk feeder
Can be divided into single-layer structure and multi-layer structure. Single-layer tray feeder is directly mounted on surface mounter feeder frame, taking up more than one bad position, applicable to the tray type material is not much. Multi-layer tray type feeder has multi-layer automatic transfer tray, occupies little space, compact structure, suitable for tray material is more of the case, tray components are mostly for a variety of ICintegrated circuit components.
In the use of palletized material, need to pay attention to keep the large tube corner exposed components, in order to prevent damage to mechanical and electrical properties caused by transportation and use. When using TQFP, PQFP, BGA, TSOP and SSOPs components in the tray, the tray size can be up to 150mm x 330.2mm with a height of 25.4mm. It is interesting to note that the tray feeder can not only be supplied to the surface mounter to pick up components, but also can be used as a potential throwing station for valuable components.
3. Stick Feeder
Tube feeders usually use a vibrating feeder to ensure that the components in the tube continue to enter the patch head to absorb the position, generally PLCC and SOIC is used in this way to feed. Tube feeder has a good protection of component pins, stability and standardization is poor, the production efficiency of the bottom of the characteristics.
4. Bulk feeder (Vibrating Fiducials)
Bulk box feeder, also known as vibratory feeder material, the way it works is the components are freely loaded into the molded plastic box or bag, through the use of vibratory feeder or feeder tube components in turn into the mounter, this way is usually used in the MELF and small form factor half-conductor components, only applicable to the sex of the rectangular and columnar components, and does not apply to the sex of the components. Characteristics: Vibration feeder is more expensive.
5. Vibration Feeder
Special flyer, need to be customized, the current production of better.
