Over recent years the electronics manufacturing industry has seen a shift away from wave soldering towards reflow soldering [1]. However, although wave soldering is indeed mature (first used during the 1950’s [eg 2]), there is still significant activity with novel process development to match [3]. This paper concerns a new type of noclean liquid flux for wave soldering that is based on water [4...

We described the synthesis of Au coated SiO2 nanoshells linked with NH2 biomolecular ligands using a simple wet chemical method with a particular application for laser tissue soldering. Tunable nanoshells were prepared by using different gold colloidal concentrations. The nanoshells are characterized by UV-vis spectroscopy, FTIR, XRD and AFM. The FTIR results confirmed the functionalized surfac...

BACKGROUND AND OBJECTIVES In this in vitro feasibility study we analyzed tissue fusion using bovine serum albumin (BSA) and Indocyanine green (ICG) doped polycaprolactone (PCL) scaffolds in combination with a diode laser as energy source while focusing on the influence of irradiation power and albumin concentration on the resulting tensile strength and induced tissue damage. MATERIALS AND MET...

Gold coated silica core nanoparticles have an optical response dictated by the plasmon resonance. The wavelength at which the resonance occurs depends on the core and shell sizes, allowing nanoshells to be tailored for particular applications. The purposes of this study was to synthesize and use different concentration of gold nanoshells as exogenous material for skin tissue soldering and also ...

Today’s wave soldering processes solder electronic assemblies within the large eutectic tin lead processing window. The issues surrounding the conversion to lead free assembly are multiple and varied. Logistics, cost, material selection, and equipment choices/options are some of these challenges that require planning and organization. However, at the core of lead free assembly is soldering. The...

What automated soldering methods can be considered for Mini-Circuits surface-mount components? There are two basic methods: reflow and wave soldering. Generally, reflow soldering can be done when (l) there are only surface mount components, or (2) these are present together with through-hole components and the latter will be soldered in a separate (wave soldering) step. The surface-mount compon...

In the study, embedded BASIC Stamp 2 (BS2) microchip controller is used to design with Hopfield neural network (HNN) as the foundation of sample training, which applies for a soldering platform of mechanical vision and accomplishes PCB soldering positioning technology. The proposed system design method in this paper can be divided into two parts: 1) the control rules of RC servo motor is design...

OBJECT The goal of this study was to use a modified version of the CO2 laser-soldering system to develop a simple and reliable technique for the repair of dural defects after excision of brain tumors. METHODS The authors used a CO2 fiber optic laser system that they had developed for heating, monitoring, and controlling tissue temperature in situ and in real time, thereby reducing damage to t...
