Other uses include drying etched elements before they leave the etcher and leveling solder on circuit boards. Air knife: A device that uses high-pressure streams of air to eliminate static and clean dust and other particles from material. Air hood: An enclosed or covered area with circulating air to ensure a dust-free, uniform environment (temperature, humidity, anti-static) during lay up of sheet materials or calibration of temperature sensors. Air box: A small, bench-mounted box that supplies filtered air at a uniform temperature during temperature sensor calibration. Adhesiveless polyimide: See all-polyimide. Adhesive tack: The process of pressing an adhesive for minimum time, temperature, and pressure to obtain an adequate bond for further processing without curing the adhesive. Solder will not stick to the adhesive, and consequently the annular ring is reduced. Excess adhesive that has squeezed out from under the cover during lamination. The process of molten adhesive filling the valleys between conductors or strands during lamination. Other adhesives used are epoxy, PSA, and RTV. Film adhesives such as FEP, CMC, and WA are adhered using heat and pressure and may be either thermosetting or thermoplastic. Adhesive: A material used to bond things together. Adhesion: The property of one material to remain attached to another. Adding a catalyst to an epoxy so that it hardens. Chemically treating a nonconductive material to prepare it for electroless plating. A chemical process that promotes a good initial plating bond of a plated metal to a base metal. Acrylic: A thermosetting plastic, commonly used as an adhesive. Its use is limited to low volume or prototype circuits, heaters, and printed circuit boards where location and hole size must be very accurate. Acro-drill : A single spindle drill that makes use of a magnified viewing microscope to precisely locate holes to be drilled. Acid brush: A small, hand brush used in various cleaning processes. Acid: Compounds, chemicals, and solutions with a ph less than 7 that can neutralize a basic solution. Acetylene torch (mini torch): A small, hand-held torch used to fuse element wires together. Acetone will soften or attack most paints, plastics, and adhesives. Acetone removes grease and oils from Kapton, foils, glass and photographic negatives. Acetone: A clear, flammable, solvent which evaporates quickly and is used for cleaning. The difference between the preferred and actual characteristic of a tool or part. How much a measurement made by an instrument differs from the true value.
Access holes allow electrical access to heater elements, tabs or circuit conductor pads and through-holes. Access hole: A hole punched, drilled, or skived in the cover layer of a heater or flex circuit. Also defines which artwork to use when etching Rubber Heaters.

Our solution is this all-encompassing, thousand-term glossary, just the thing to tell Microsection and Micrometer apart. Not only are a lot of the vocabulary simply unfamiliar, sometimes a word means one thing in one industry and something else altogether in a different one. Even engineers might scratch their heads if it s a term from outside their specialty. 2 Minco Glossary of Terms Accurate, rugged, and weatherproof temperature sensors Overview There s no doubt about it, the engineering world is rife with obscure jargon and technical terminology.
