In a PCB assembly factory, a complete printed welding procedure should include the following aspects:
(1) welding data of PCB components. In short, welding data of components is to specify the position, Angle and model of components to be pasted on the PCB.SMT data include component model, bit number, X coordinate, F coordinate, placement Angle, etc. The origin of coordinates is generally taken in the lower left corner of PCB.
(2) benchmark data.It includes reference points, coordinates, colors, brightness, search areas, etc.Before the start of the welding cycle overlooking the cameras in the patch head first search benchmark, found that after the benchmark, cameras read its coordinates, and sent to SMT microprocessor system for analysis, if there is error, issue instructions by computer system by pasted on the mobile making PCB precise positioning control execution parts, reference point should be at least two, to ensure the accurate location of PCB.
(3) component database.In the library, there are component size, pin number, pin spacing and corresponding nozzle type, etc. (4) arrangement data of the feeder.The feeder array data specifies the selected feeder for each component and its placement on the SMT feeding platform
(5) PCB data.PCB data include setting PCB size, thickness, assembly data, etc
Different manufacturers, different models of the patch machine software programming method is not the same, especially high-speed and high-precision patch machine programming more complex, more constraints, here is not detailed, if you need to learn more information, please pay attention to us.
Pcb has many production procedures, so there are often some defects in the process of printed circuit board production, which futher affects the quality and reliability of the product. The quality of pcb is determined by the following factors: design quality, material quality, on-site management....
