Abstract

Though lead‐free replacements for SnPb eutectic alloys for reflow, wave, and hand soldering have been developed, relatively little has been reported on practical experience of lead‐free wave soldering processes. In wave soldering, the interaction between the PCB, flux, solder alloy and processing equipment makes it desirable to develop the consumables and the wave soldering machine concurrently. A crossfunctional project team was formed and a lead‐free wave soldering process developed and validated through nine months of industrial use in production of broad‐band communications technology products.

Abstract

This paper outlines the current position of water based no‐clean liquid fluxes for wave soldering. The primary differences between these and “traditional” alcohol based liquid fluxes are explored using wetting balance methods. Reduced wetting capability (of the flux onto the PCB) can be addressed by using various surfactant additives; improved solderability is due to enhanced acid activator dissociation resulting from increased solvent polarity. Regarding implementation in a production environment, there is only minor impact. A slightly increased preheat capability is required, and foam application demands tight control of the feed gas flow rate. More generally, in addition to the “headline” environmental benefit of reduced VOC emissions, water based liquid fluxes confer significant handling advantages, for example zero flammability and low odour/evaporation at room temperature. Against this background, it is suggested that water based liquid fluxes will become ever more popular.

Abstract

Commencing with the June 1972 issue, Industrial Management will be both published and printed by Wilding & Son Limited of Shrewsbury, who have recently purchased this Journal from the Mercury House Publishing Group. The quality of the editorial and its forward‐looking policy will remain unchanged under the editorship of John Lawless, whilst plans are formulated for the injection of new initiatives under the fresh leadership of Wildings.

Abstract

It has often been said that a great part of the strength of Aslib lies in the fact that it brings together those whose experience has been gained in many widely differing fields but who have a common interest in the means by which information may be collected and disseminated to the greatest advantage. Lists of its members have, therefore, a more than ordinary value since they present, in miniature, a cross‐section of institutions and individuals who share this special interest.

Abstract

Since the late 1950s it has been recognised that the systems used internally within supply chains can lead to oscillations in demand and inventory as orders pass through the system. The uncertainty generated by these oscillations can result in late deliveries, order cancellations and an increased reliance on inventory to buffer these effects. Despite the best efforts of organisations to stabilise the dynamics generated, industry still experiences a high degree of uncertainty from this source. The “supply chain complexity triangle” describes the interaction of deterministic chaos, parallel interactions and demand amplification. It provides a framework for understanding the generation of uncertainty within supply chains. The implications for supply chain strategy and manufacturing logistics are discussed.

Abstract

The pattern of prosecutions forfood offences has changed very little in the past decade. Compositional offences have rarely exceeded 5 per cent and, since the 1967 batch of regulations for meat products, are mostly in respect of deficient meat content. Food hygiene offences have also remained steady, with no improvement to show for all the effort to change the monotony of repulsive detail. The two major causes of all legal proceedings, constituting about 90 per cent of all cases—the presence of foreign matter and sale of mouldy food—continue unchanged; and at about the same levels, viz. an average of 55 per cent of the total for foreign matter and 35 per cent for mouldy food. What is highly significant about this changed concept of food and drugs administration is that almost all prosecutions now arise from consumer complaint. The number for adulteration as revealed by official sampling and analysis and from direct inspectorial action is small in relation to the whole. A few mouldy food offences are included in prosecutions for infringements of the food hygiene regulations, but for most of the years for which statistics have been gathered by the BFJ and published annually, all prosecutions for the presence of foreign matter have come from consumer complaint. The extent to which food law administration is dependent upon this source is shown by the fact that 97 per cent of all prosecutions in 1971 for foreign bodies and mouldy food—579 and 340 respectively—resulted from complaints; and in 1972, 98 per cent of prosecutions resulted from the same source in respect of 597 for foreign matter and 341 for mouldy food. Dirty milk bottle cases in both years all arose from consumer complaint; 41 and 37 respectively.
