Are you still verifying your PCB prototype visually?
After completing component placement, it may take months for designer to complete the routing process and finish the entire PCB layout. At this point the CAM data can then be handed out to manufacturers for PCB manufacturing and assembly. After investing this much time and effort, you would probably expect the final prototype to be built as expected, with high quality and reliability.
Are your alternative parts well validated before release
In alternate part selection, many aspects need to be considered: electrical function, physically fit, supply chain flexibility, cost, etc. Every aspect is important during alternative part selection, but realistically, electrical and physical fit are the main prerequisites when choosing a new alternative part.
Strengthening PCB Solder Connections
To increasing the overall solder strength within a PCB design, designers should be focusing on two distinct but related factors: The material composition of the solder, and the pad and footprint layouts for individual components. The composition of the solder itself will depend upon the application of the board, the components, construction method and materials within the board, and the overall final board quality. The overall footprint of the component will be dependent upon the components within a BOM and the recommended assembly guidelines of your assemblers. Both of these factors rely on discussions and interactions with your assembly house and leaving these discussions until after the design has been released ultimately limits your assembly options.
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.
Manufacturing Driven Design – Taking DFM to the Next Level
Manufacturing Driven Design (MDD) is an evolutionary approach to DFM. It enables the effortless exchange of manufacturing process constraints so that an OEM can assess the manufacturability of a design in perfect alignment with their supplier
What is DFM and DFA?
DFM and DFA are relevant to almost any product be it assembling bicycles where primarily the product is mechanical components to electronic devices such as cell phones, routers, and computers which require both mechanical and electrical components. The primary focus of this blog will be PCB Design through PCB Fabrication and PCB Assembly within the electronic realm and how it relates to DFM and DFA.
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.
