Stencil design considerations during library cell design
Library cell design seems to be an easy part of the entire design process, but in reality, it can be a complicated part of this process, as it involves many different aspects to consider. It should not only comply with the electrical needs, but also needs to meet manufacturing requirements. Solder paste printing is one of the manufacturing processes that may need considerations during your library cell creation. To be more straightforward, the stencil design is something need to be considered during library cell design.
How to Optimize PCB Design for the SMT Assembly Process Flow
PCB (Printed Circuit Board) design layout optimization is critical for the success of SMT (Surface Mount Technology) assembly. SMT assembly involves placing surface mount components directly onto the surface of the PCB, as opposed to through-hole components, which require holes to be drilled through the PCB. SMT assembly is faster, more precise, and more cost-effective than through-hole assembly, but it requires careful design optimization to ensure a successful assembly process.
Making Parts Part of Manufacturing Driven Design
When it comes to PCB assembly level MDD, many designers have not concerned themselves with the component manufacturing Bill of Material (BOM). Designers work from a CAD library that has component libraries associated with internal part numbers (IPN) their company uses. The CAD Design Rule Checking software uses those CAD library shapes for its analysis and even, in some cases, the avoidance of where components are placed. There is nothing wrong conceptually with this mentality. However, like all things, the details matter.
