DFX, abbreviation for Design for X, is also written as Design for Excellence or Design For Excellence (DfX or DFX). In electronic manufacturing industry, DFM (Design for Manufacture) and DFA（Design for Assembly）are two commonly-used NPI design methods.
With DFM software, design and manufacturing are no longer two separate processes, but interact with each other. DFM/DFA analysis could be conducted in PCB design stage to make the design fit the process technology, thus reducing reworking times and shortening NPI cycle.
DFM or Design for manufacturability, is not only to fulfill the requirements of product’s function, appearance and reliability, but, more importantly, to take the manufacturability of product into account since the beginning of product design, thus making a high-quality product at lower cost and shorter time.
It may not be strange for SMT (Surface Mounted Technology) engineers to programme for panelization with multiple & free-angle boards. By traditional method, engineers may face great challenges to complete this task. These challenges will not only affect engineers’ programming efficiency and correctness, but result in cost increase as well as quality risks.
During communication with customer at field, R&D department, Process department and QA department, etc. may participate in the discussing, while different departments have different focuses. Vayo’s NPI(New Product Introduction) series software covers each process from design to manufacturing, including both advanced DFM simulation solution and elementary Gerber view tool.
Very interesting! Solder paste stencil Is quite cheap, but It Is core process step for PCB assembly (SMT) since >70% quality problems are from screen printing process.
Lots of people may have been impressed with the powerful function of 3D DFM(Design for Manufacturing)/ DFA(Design for Assembly) capability of VayoPro-DFM Expert software. Today we would like to demonstrate another useful function of Vayo’s DFM Expert software.
Currently, most programming process of PCB panelization requires input of measured data, such as outline data, matrix offset, etc., and this method tends to cause deviation of coordinates of component mounting location, thus causing incompliance during boards mounting.
Kelvin Four-terminal sensing, also called four-wire sensing or four-point probe method, is an electrical impedance measuring technique, which uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurement than two-terminal sensing.
