“…Li et al (2012) built a test system and simulated filter circuit via software for meter products to comply with EFT test standards required by regulations. Ker et al (2010) used the collaborative design of hardware and firmware for display panel products, such that firmware is used to recover the system automatically when equipment under test (EUT) is subject to interference. However, EFT may interfere with EUT with noise by using pulses in various forms such as electromagnetic induction, radiation and conduction, but software simulation cannot consider the various interference forms mentioned above concurrently.…”

Purpose The purpose of this study is to use the Taguchi Method for parametric design in the early stages of product development. electromagnetic compatibility (EMC) issues can be considered in the early stages of product design to reduce counter-measure components, product cost and labor consumption increases due to a number of design changes in the R&D cycle and to accelerate the R&D process. Design/methodology/approach The three EMC characteristics, including radiated emission, conducted emission and fast transient impulse immunity of power, are considered response values; control factors are determined with respect to the relevant parameters for printed circuit board and mechanical design of the product and peripheral devices used in conjunction with the product are considered as noise factors. The optimal parameter set is determined by using the principal component gray relational analysis in conjunction with both response surface methodology and artificial neural network. Findings Market specifications and cost of components are considered to propose an optimal parameter design set with the number of grounded screw holes being 14, the size of the shell heat dissipation holes being 3 mm and the arrangement angle of shell heat dissipation holes being 45 degrees, to dispose of 390 O filters on the noise source. Originality/value The optimal parameter set can improve EMC effectively to accommodate the design specifications required by customers and pass test regulations.

“…Li et al (2012) set up test system for ammeters with software simulated filter circuits to meet EFT test standards given by relevant regulations. Ker et al (2010) uses hardware and firmware collaboration design to auto recover system of panel products when the equipment under test (EUT) is interfered. This remains ineffective as EFT noise interference to the EUT may come in group of different impulses, including electromagnetic inductance, radiation and conductance, where no software simulation is able to counterbalance all of them at the same time.…”

Purpose Differing from previous studies trying to solve the electromagnetic compatibility (EMC) issue by addressing single factor, this study aims to combine measures of shielding, filtering and grounding to design parameters with the Taguchi method at the beginning of product design to come up with the optimal parameter combination. Design/methodology/approach EMC-related performance such as radiated emission, conduction interference and electrical fast transient/burst immunity (EFT) are response variables, whereas the printed circuit board and mechanic design-relevant parameters are considered as control factors. The noise factors are peripherals used together with the tablet. Findings The optimal design parameter matrix based on results from the application and integration of multivariate analysis method of principal component grey relation and technique for order preference by similarity to ideal solution suggests 14 grounding screw holes, cooling aperture of casing at diameter of 3 mm and staggered layout and 300O filter located at source of noise. Validation of this matrix shows around 10, 1 and 8 per cent improvement in radiation, conduction interference and EFT immunity. Originality/value The multivariate quality parameters’ design method proposed by this study improves EMC characteristics of products and meets the design specification required by customer, accelerating electronic product research and development process and complying with electromagnetic interference test regulations set forth by individual country.
