ESD and SMD

Many modern electronic components are vulnerable to electrostatic discharge, ESD, and may also be miniscule surface mount devices, SMD, ( typically with dimensions of only a few hundredths of an inch ), for circuit boards using surface mount technology, SMT. The synthesiser chip, which I referred to on 17th May, is both. Since then I have assembled the necessary tools, materials and aids to work successfully with such components.
On the heat-resistant anti-static work mat I've placed some other ESD accessories; wrist-strap, anti-static brush and earth plug.
For soldering and handling I have a 48 watt temperature controlled soldering iron, tips with sub-millimetre pointed ends, 0.38, 0.56 and 0.70mm diameter solder, solder-wick ( size AB ), liquid flux, solder paste, iso-propyle alcohol for cleaning off flux residue, tweezers and a swivel mounted vice. Regarding the vice, mine has a groove along the length of the jaws, making it ideal for holding circuit boards.
Obviously it is fundamental to be able to see the SMT components properly. So to help me in this regard, and also for inspecting my work, I've collected various types of optical aids, handheld and hands-free, with magnifications from x1.5 to x20. The adjustable 2.5 watt LED light will illuminate the work surface without too much glare or shadow.
All that is now left to chance is a steady hand !
