Similar to design for manufacture (DFM) and design for assembly (DFA) (which seek to avoid designs which are difficult to make), the concept of DFI considers measurement capabilities at an early stage in the product development life cycle and uses knowledge of the fundamental principles of metrology to achieve cost reduction. If the inspection ...
PD 5500 is a specification for unfired pressure vessels.It specifies requirements for the design, manufacture, inspection and testing of unfired pressure vessels made from carbon, ferritic alloy, and austenitic steels.
This gives rise to the terms design for manufacturability (DfM, DFM), design for inspection (DFI), design for variability (DfV), design for cost (DfC). Similarly, other disciplines may associate other traits, attributes, or objectives for X. Under the label design for X, a wide set of specific design guidelines are summarized. Each design ...
The history of testing, inspection and certification services spans back several centuries. In the late 19th century, following the advent of the Industrial Revolution and the considerable risks involved with high-pressure steam boilers, specialized institutions emerged across Europe which carried out periodical inspections of such vessels to assess their overall condition as a precautionary ...
In scan-design, registers (flip-flops or latches) in the design are connected in one or more scan chains, which are used to gain access to internal nodes of the chip. Test patterns are shifted in via the scan chain(s), functional clock signals are pulsed to test the circuit during the "capture cycle(s)", and the results are then shifted out to ...
Computer-aided inspection (CAI) is the use of software tools to assess manufactured objects. [ 1 ] [ 2 ] It is closely related to computer-aided design (CAD) and computer-aided manufacturing (CAM). Its primary purpose is to allow engineers to more quickly and precisely assess the physical properties of manufactured objects.
Design and development planning; Design input, including intended use and user needs (also known as customer attributes) Design output, including evaluation of conformance to design input requirements through: Design verification confirming that the design output meets the design input requirements ("did we design the device right?")
Inspection and measurement of the thickness of the different layers of an electronic chip using THz and X-ray radiation. THz has the privilege of being non-ionizing (non-destructive) but the resolution of X-ray is higher. [2] Quality related in-process inspection/verification is an essential part of quality control in manufacturing.
