Here Chris talks about the pitfalls, the paucity of safe options for manufacturers seeking rare components, and his exasperation with organisations that appear to shelve common sense at the first sign of a shortage. He shares his ‘no nonsense’ approach to getting things right first time, and explains his thinking in establishing an independent distributor focused exclusively on delivering 100% component integrity.

Quality standards are getting tougher each year. In these difficult times, wire harness manufacturers are looking to expand business in their existing markets and are looking for new markets. The following article will compare and contrast the current quality standards that are most commonly used today. It will review proper measurement techniques, discuss some trends in crimp quality, and address methods to improve efficiency in quality data collection.

Reflow soldering in a nitrogen atmosphere is a common process consideration in surface mount technology assembly. This is because the use of nitrogen in reflow equipment may benefit the process as well as the quality of the end product, where it can increase the reliability of the solder joint. (...) The present study investigated thoroughly the effect of different reflow soldering atmosphere, which is air and nitrogen on IMC formation and growth

Intermetallic compounds (IMC) in solder bonds are commonly considered critical for the reliability of interconnections. The microstructure and thermal aging characteristics of solder bonds of crystalline silicon solar cells are investigated, whereby two solders, Sn60Pb40 and a lead-free, low melting point alternative Sn41Bi57Ag2 are considered.

A new PCB surface finish has been developed that offers outstanding performance and excellent environmental protection. This finish has the potential to replace more common finishes such as ENIG, ImAg, ImSn, ENEPIG, or OSP with a chemically resistant plasma deposited coating. The substitution of the wet processes with this dry plasma process offers significant advantages e.g. lower quantities of chemicals used, environmental benefits and improved operator safety.

As a speed type air compressor, centrifugal compressor can generate air flow moving in radial direction. Centrifugal air compressors are used by a large number of companies today because of their high-pressure tightness. Therefore, common faults in the operation have become one of the most concerned issues for users. This article will discuss causes of centrifugal compressor failures and give corresponding maintenance measures. At the end, OKmarts has listed the problems and solutions in detail for your quick reference.

In this article we will examine if there is a measurable difference in the printing performance when using stencils which have a higher tension than is commonly accepted in the industry. Alpha's new tensoRED™ High Tension Frame System will be introduced during this wider examination. We will examine their effect in terms of controlling variation in critical deposit volumes and what, if any effect on positional accuracy can be seen.

The overall process of manufacturing electronics assemblies is characterized by a number of very different procedures. Along the production chain, technologies for cutting, assembling, soldering, bonding, gluing, marking, potting, etc. are used, all of them have one thing in common: They produce airborne pollutants, some of which can have a significant impact on employees, manufacturing equipment and products - and for this reason need to be removed effectively and efficiently.

The remainder of this paper will deal with the adhesive cure mechanism most often found in the microelectronics industry; the thermal activation and cure of adhesives that are most commonly based on epoxy backbones. The use of heat is already prevalent in the microelectronics industry as most printed circuit board assemblies use some element of this thermal energy (reflow ovens for example) during the component soldering and assembly stage or during their burn-in stage (convection ovens).
