There are currently several methods for checking the spacing distance
between components using the Unisoft software. For example find components
that are within 200 mils of each other. For more details on these methods,

DFM / DFA checks the Unisoft

Design for Manufacturing / Assembly (DFM / DFA) for PCB
manufacturing is a very broad and complex subject area. DFM / DFA in PCB
electronics manufacturing is a comprehensive approach aimed at designing
PCBs in a way that makes them easier and more cost-effective to manufacture.
DFM / DFA checks focus on optimizing the design of a PCB to ensure it meets
manufacturing capabilities while minimizing potential issues that could
arise during the manufacturing process. The goal is to improve the overall
efficiency of production, reduce costs, and ensure the quality of the final
product. Most aspects of DFM / DFA are addressed during the design phase of
a printed circuit board (PCB), utilizing sophisticated software and
techniques provided by various CAD systems. These systems are essential for
designing PCBs, and there are hundreds of DFM / DFA criteria that need to be
checked. When done correctly, adequate DFM / DFA measures should be in place
before the assembly and testing of the board begin. The Unisoft software,
which imports various CAD files and bills of materials (BOM) from the PCB
CAD Design Systems, can assist in verifying that DFM / DFA has been properly
applied to the PCB design in certain areas. For more details on these methods, contact Unisoft directly
or use the online help tooltips provided.
Areas where
the Unisoft software may assist in verifying that DFM / DFA was executed properly:
Component Placement: Checks for proper spacing
between components to allow for efficient assembly and to minimize issues during
soldering processes.
Electrical Testing and
Accessibility, Test Points: Incorporates test points to facilitate easy
testing of the final PCB for functionality and quality assurance.
Ensuring that the
PCB design supports comprehensive electrical
testing is another critical DFM / DFA consideration. This includes the placement
of test points, accessibility for test fixtures, and
the
inclusion of features that facilitate in-circuit testing (ICT) or flying probe
testing.
Assembly and Fabrication Notes: Includes
detailed notes and specifications for the manufacturer regarding assembly
processes, material requirements, and any special
handling or processing needs.
Supply Chain Considerations -
DFM / DFA can extend to include considerations of the supply chain, such as the
availability of components, lead times, and the impact of using
alternate parts.
Early consideration of these factors can help in avoiding delays and redesigns due to parts being unavailable or
having longer than expected lead times.
The Unisoft
software lookup by manufactures part number, etc. feature can aid in this
area.
