Abstract

Purpose

The purpose of this paper is to analyze and investigate analyzed core operational problems of aquatic products with food traceability system and their performance in the Taiwanese market and to develop the marketing strategies to solve these core operational problems.

Design/methodology/approach

Based on all of the core operational problems derived from the literature, the paper interviewed distributors and aquatic product producers and collected their ideas to resolve the above problems. Then, the study applies the TRIZ theory to find the improving and worsening parameters for those issues, based on which the study can develop strategies to improve the marketing model of aquatic products with food traceability systems to solve operational problems.

Findings

The findings of the study are of three fold: identified seven core problems of aquatic products with food traceability systems; identified seven strategies for improving marketing model to solve operational problems of aquatic products with food traceability systems and developed the new marketing model to solve operational problems for aquatic products with food traceability systems.

Practical implications

Promoting the food traceability certification comprehensively cannot only improve the food safety in Taiwan but also improve the competitiveness of Taiwanese industries as well as help to expand to the international market.

Originality/value

The contribution of this study lies in extending the body of knowledge of application of TRIZ methodology in marketing model for aquatic products with food traceability systems. The findings of this study can be used as a reference for aquaculture products with traceability systems in other countries, as food safety is a globally growing trend.

Abstract

Purpose

An investigation has been performed on the improved solder wettability of oxidized aluminum (Al) with lead-free solder (96.5Sn-3.5Ag) using Ar-H2 plasmas. The lead-free solder wettability was raised from 62.2 per cent wetting for Al oxidized in air at 250 C for 4 h to 98.4 per cent wetting of oxidized Al modified by Ar-H2 plasmas at a certain H2 flow rate. This study aims to gain insight on the surface characteristics of Al affecting the solder wettability with a liquid lead-free solder.

Design/methodology/approach

Ar-H2 plasmas at certain H2 flow rates are intended to reduce Al oxides on the surfaces of oxidized Al substrates both by physical bombardments via Ar plasmas and chemical reductions with H2 plasmas, while Al substrates are exposed in Ar-H2 plasmas to improve the solder wettability with a liquid lead-free solder.

Findings

Surface characteristics of oxidized Al substrates have been identified to play key roles for enhanced lead-free solder wettability using Ar-H2 plasmas. A decrease in polar surface free energy and an increase in dispersive surface free energy on the surfaces of oxidized Al substrates are exploited to advance the lead-free solder wettability. Decreased composition ratios of O to Al, detected by X-ray photoelectron spectroscopy (XPS) for oxidized Al substrates, are crucial for improved lead-free solder wettability.

Originality/value

XPS is typically used to analyze the surface compositions of Al oxides. To provide a rapid and non-expansive method to identify the surfaces of Al substrates prior to soldering to assure lead-free solder wettability, this study proposes a measurable skill, a so-called sessile drop test method, to investigate surface free energies such as total, polar and dispersive surface free energy on the surfaces of Al substrates, to illuminate how the lead-free solder wettability of oxidized Al is improved by Ar-H2 plasmas.
