Quality assurance starts with the handover of the production data!

Defect-free products are crucial if a company is to remain competitive in the long term. Meeting this requirement depends in turn on robust, capable production processes. But how can high quality best be ensured in production and how can companies move toward “zero-error production”? It undoubtedly all starts with the provision of the production data in the “right” format.
 
CAD data:
A CAD file incorporates the complete description of the printed circuit board design. This includes, for example, the component shapes and the absolute component rotation or polarity. With polarised components, information about the alignment is important, since access to the design data (with clear symbols) is direct, without further interpretation. It must therefore be ensured that these components are equipped as described in the data. Using the component shapes (geometric data), it is possible to have an overview at the press of a button of the component density (SMD & THT) and complexity. A CAD file is imported without further post-processing into the productware production tool and linked with the customer’s parts list. This forms the basis for the necessary programs for the SMD machines and the production documentation / work plans.
 
XY data:
XY position coordinates contain basic information (component, XY coordinates and angle of rotation per position) which needs to be supplemented by hand and edited before further processing. Because of the manual editing at parts level and checking of the alignment of polarised components, the work required is much more time-intensive and less reliable. This data also provides no overview of the placement density. In addition, the work plans have to be prepared manually using data sheets when it comes to the geometric shapes.
 
Summary:
CAD data in ASCII format can offer major quality and time advantages. They are very reliable for preparing the placement programs for SMD machines, in production documentation for SMD and THT placement and in quality control (QA).
 
 
CAD data are usually generated directly from your layout system. If you have any questions about the output from your CAD system, please get in touch with us. We are able to import the most common CAD formats. Don’t hesitate to contact us!
