SMART MANUFACTURING
various global manufacturing facilities all deploy the same software, an extra layer of security is provided for end-customers requiring seamless global product transitions. Facilities share specific rules that are set up in the Valor Process Preparation tool, allowing a consistent approach in how CAD data is viewed and then merged with materials and components lists to build a virtual PCB. The platform performs multiple design rule checks on the PCB layout. The BOM is virtually compared to its supporting CAD data; with components visualized, the manufacturer is empowered to catch potential errors before assembly takes place.
REAL-WORLD RESULTS OF DFM ANALYSIS By introducing DFM within the design phase, total product cost and NPI iterations can be reduced. In one scenario experienced by TT, the company given the opportunity to provide DFM feedback on a new printed circuit board (PCB) design, prior to the final revision being released to production. Through analysis, it was discovered that some surface mount components were positioned too close to the pin-through connector. Ideally, a minimum of 3mm copper-to-copper clearance is required to allow for automated soldering and de- risking any solder defects. In addition, it was discovered that there were a number of 'via holes' in SMD pads which needed to be plugged and capped to prevent solder from wicking away from surface mount pads during assembly and solder reflow. There are many common design errors detected by Valor Process Preparation during the DFM analysis process. Device designers can anticipate DFM analysis to reduce the number of design revisions required to bring a new design to volume production release. The process also improves the reliability of a design by locating manufacturing risks ahead of the production process. Product development speed must be paired with precision, enbled by DFx. As subcontractor relationships continue to grow in the electronics industry, shared insight and feedback is essential to the processes driving the design and manufacture of a product. Variables always must be considered, but DFx increases overall confidence in product development and facilitates a faster time to market, ensuring that products are reliable and testable. The DFx framework itself provides the interface between design and manufacture to ensure a smooth transition to production – creating an opportunity to determine and correct issues in new products as well as mature, or already developed products. It is true that a great design team devises a product that fulfills the needs defined by the market. But in this effort, it is essential to design for manufacturability, testability, supply chain, quality, and more before the actual production for efficient processes and a reliable product outcome. Great engineering design practices start with careful consideration of the product requirements to reduce delays and redesign costs later.
