The PCB board is the equipment that we need to mount components in the SMT placement machine production line. Usually, the use and inlay method of the PCB board will have an impact on our process of mounting components. So how should we properly handle and use the PCB board in the SMT placement machine, let's take a look.
Panel Size All machines have a specified maximum and minimum panel size that can be processed.
fiducial marks fiducial marks are simple shapes in the routing layers of a printed circuit board, the placement of these shapes should not be confused with other aspects of the circuit board design
When designing printed circuit boards, it is common to place components near the edges. Therefore, panel processing of printed circuit boards is very important due to the printed circuit board handling mechanism in various machines.
SMT placement machine vision systems use fiducial marks to ensure that all components are positioned correctly. When aligning the PCB with the machine, the furthest reference point is recommended for maximum accuracy, and three reference points are recommended to determine if the PCB is loaded correctly.
Size and Location of Components A populous design may place smaller components near larger components, which needs to be taken into account when generating the placement program. All smaller components need to be placed before larger components to ensure they are not disturbed - placement SMT program optimization software usually takes this into account.
In the SMT placement machine, we need to correctly use and process the PCB board. If we want to configure it reasonably, we must carry out the work tasks carefully, so as to maximize our benefits.
