SMT placement program settings: SMT placement program settings refer to the placement program environment settings, such as machine configuration, coordinate reference origin, component database selection and feeder database selection, etc.

 

The configuration of the machine is the basic setting environment of the placement program. The configuration of the placement machine includes: the type of placement head; the location, type and accuracy of the camera; the parameters transmitted by the circuit board; the type and number of nozzles stored in the machine; automatic tray The parameters of the feeder; the parameters of each coordinate axis of the machine, etc.

 

The coordinate reference origin refers to the difference between the coordinate origin of the circuit board and the coordinate origin of the patch component. The coordinate system directions of different devices are different. When the coordinate origin of the circuit board is at the corner of the circuit board, the coordinates of the patch component are based on the corner of the same direction of the puzzle or a certain reference point as the origin.

 

The component database includes the length, width and thickness of the component, the size of the component feature, the span, and the package of the component. For different machines, the component database includes the models of the placement head and nozzle, the light intensity of the recognition camera, the model and direction of the default feeder of the component, and the recognition method and special requirements.

 

 

Some machines can be configured to store multiple component databases according to different product series, and can call different databases when needed. The feeder database is like a component database, which can store multiple feeder databases, which can be selected according to actual needs.

 

The size of the circuit board and how to join the board. SMT placement machine programming needs to adjust the width and transmission distance of the circuit board conveyor track according to the size of the circuit board, and the support device of the circuit board can also adjust the height according to the thickness of the circuit board. The circuit boards of general products use a single product, and some products are not conducive to the production of chip equipment because the size of a single circuit board is too small. In order to improve the productivity of the equipment and reduce the transmission time of the circuit board, a multi-product jigsaw method is adopted. For multiple product panels, when entering the component placement list, only one panel component needs to be entered, and the component positions of other panels can be automatically copied.

 

Circuit board offset correction. Circuit board offset correction refers to the use of the reference point of the circuit board for patching. The reference point of coordinate correction is some characteristic points on the circuit board. Generally, the same process as the metal pad of the printed circuit and the component is used. Produced at the same time of production, it can provide a fixed and accurate position for the overall correction of the placement position of the component.

 

The configuration of the nozzle. The program of the placement machine can be optimized according to the nozzles currently stored in the machine or the nozzles are not limited. If it is optimized according to the currently stored nozzles, there is no need to reconfigure it, and if it is optimized according to the unrestricted nozzles, it needs to be reconfigured.

 

Product component placement list. The placement list includes the component's tag number, material code, X/Y coordinates, and placement angle. This is the key data required for surface mounting and determines the exact location of the component on the PCB.

 

Feeder list. Including the component code of various components, the feeder model used, the location identification code and the correct orientation of the component on the feeder. When an individual new component is added to the component placement list, this component will be automatically added to the feeder list according to the model of the default feeder in the component database. If an individual component fails to be recognized, the component will be thrown away according to the setting of the throwing station in the component database or program.

 

The above is about the parameters that need to be operated in the programming of the SMT placement machine, I hope it can be helpful to everyone!
