Operating Steps of Chip Mounter Programming
How to learn SMT placement machine programming? What programming steps are required? This is the technology that many SMT basic operation technicians want to learn Relatively speaking, there are some differences in programming. SMT places machines of various brands, but the overall programming rules and operating procedures remain unchanged What is the smt placement machine programming?
SMT mounting program setting
SMT mounter mounting program settings refer to the mounting program environment settings, such as machine configuration, coordinate reference origin, component database selection and feeder database selection.
1. The machine configuration is the basic setting environment for the patch. The configuration of the mounting machine includes: the type of the mounting head; Position, type and accuracy of camera;
Parameters transmitted by the circuit board; Type and number of nozzles stored in the machine; Parameters of the automatic paper feeder; Parameters of machine coordinate axis; Other parameters
2. The coordinate reference origin refers to the gap between the circuit board coordinate origin and the SMD element origin. Different equipment has different coordinate system directions. When the coordinate origin of the circuit board is located at the corner of the circuit board, the coordinates of the patch element are based on the corner or reference point with the same direction as the origin.
3. Component databases: Some machines can create and store multiple component databases according to different product families, and call different databases when necessary.
4. The feeder database is similar to the component database. It can also store multiple feeder databases, which can be selected as needed.
2. The size of the circuit board to be wired refers to the size of the circuit board and the pipe connecting the circuit board
Program design The chip mounter needs to adjust the width and transmission distance of the circuit board conveyor track according to the size of the printed circuit board The support device of the circuit board can also adjust the support height according to the thickness of the circuit board The circuit boards of general products use a single product; Some products are unfavorable to the production of wafer placement equipment because the size of a single circuit board is too small, or multiple products are used to improve the production efficiency of the equipment and reduce the transmission time of the circuit board Circuit board channel For multiple product panels, when entering the component placement list, only one panel component needs to be entered, and the component locations of other panels can be automatically copied
Circuit board offset correction
Circuit board offset correction refers to using the reference point J of the circuit board to correct the chip coordinates. Reference points are some characteristic points on the circuit board. Generally, the same process is used on the circuit board as the metal pads of printed circuits and components. During production, it can provide fixed and accurate position, which is a characteristic point used to calibrate the overall placement position of components. The calibration methods of reference points on the circuit board can be divided into three types: calibrate all components on the circuit board using the reference points of comprehensive calibration; Correction of components; Use the reference point next to the component to calibrate the local single high-precision component.
Fourth, nozzle configuration
The placement order can be optimized according to the nozzles stored in the current machine or without restricting the nozzles If the nozzle is optimized according to the nozzle stored in the current machine, it is not necessary to re include the nozzle; If the nozzle is not restricted by optimization, then it is necessary to re suck the nozzle according to the list of nozzles generated after optimization The shape of the mouth
