The importance of design for manufacturability (DFM) has been extensively stressed in recent years. For PCB designers, DFM analysis is critical to ensure the manufacturability of board, and for fabricators, DFM analysis is essential to save manufacturing cost (time or material).
A PCB design would go through several rounds of DFM analysis. In the past, PCB designers could ask their manufacturing colleague to help manually check the board, while as the PCB becomes more and more complicated, the manual inspection approach is no longer applicable.
Following the industry trend, more intelligent DFM analysis tools are available on the market, like Valor developed by Siemens, and VayoPro-DFM Expert by Vayo Technology. These two DFM tools are popular and professional for DFM analysis, both in terms of fabrication and assembly.
The DFM analysis of Valor and DFM Expert includes inspection of component, padstack, pin to pad, fiducial, test point, etc. Besides, DFM Expert could inspect more items like signal, HDI, drill, backdrill and so on.
Below are some sample issues found out by DFM Expert:
Pad package design error
Wrong position of ref. Silkscreen
SMT parts too close to PTH parts, difficult for wave solder process; Surface mount component too close to connector, too difficult to rework; Inconsistent of direction, may cause wrong polarity risk; No solder mask web.
Via under BGA ball, risk for crack
VayoPro-DFM Expert is a rule-based DFM analysis tool. It comes with 1500+ checking rules, including 1200+ assembly checking rules and 300+ fabrication checking rules. These checking rules support IPC standards, like IPC-7351, IPC-A-600, IPC-A-610, IPC-TM-650, IPC-2221, and IPC 7095, …. Vayo Technology keeps innovating these checking rules and offers on-demand checking rules custom development service.
These checking rules are also an accumulation of process know-how. With the checking rules, PCB designers, upon the completion of designing work, could independently conduct DFM analysis work instead of engaging with manufacturing colleagues repeatedly in design stage. For manufactures, with the automatic DFM analysis tool, DFM analysis workload could be greatly reduced.
What’s more, VayoPro-DFM Expert could also generates 3D DFM/DFA analysis report upon the completion of automatic DFM analysis, which could help PCB assembly service provider demonstrate high level DFM/DFA capability, and help ease the communication with clients or the design department.
