 n.— «The machines, which are roughly the size of an upright piano and usually sell for between $50,000 and $80,000, pump “microdots” of molten solder through a nozzle onto the precise spot where component parts are to be attached to circuit boards. Through a simple programming method, called “bombsighting,” a camera projects close-up images of the circuit board and magnifies them on a video monitor. By using the arrow keys on a computer keyboard, an operator moves the camera’s crosshairs to a spot where solder is to be applied, then enters a keystroke into the computer to provide precise coordinates for that spot, or “bombsight” to tell the selective-soldering machine to put solder there. The coordinates of the bombsights are accurate to within a few thousandths of an inch, Cable says.» —“Next stop, global market” by Mike McLean Spokane Journal of Business (Washington) June 28, 2007.
