Soldering of printed circuit boards by moving them over a flowing wave of molten solder in a solder bath ...  3, fiche 1, Anglais, - flow%20soldering

Record number: 1, Textual support number: 1 CONT

Flow soldering is a technique used to bulk solder components onto a printed circuit board. This process is typically used when a single sided [printed circuit board] has a medium to high number of conventional or through-hole components. This process is also often referred to as "wave soldering" because of the wave-like motion the molten solder takes when applied to the [printed circuit board]. The circuit board is passed over a bath of molten solder in which a pump produces an upwelling of solder that looks like a standing wave. As the circuit board makes contact with this wave, the components become soldered to the board.  4, fiche 1, Anglais, - flow%20soldering

... the process permits precise control of the depth of immersion in the molten solder and minimizes heating of the board.  3, fiche 1, Anglais, - flow%20soldering

Through-hole technology is the mounting process by which component leads are placed into the drilled hole of a bare printed circuit board and soldered to the pads on the opposite side. This can be achieved with either manual assembly or automated insertion mount machines. Through-hole mounting was the standard practice until surface-mount technology(SMT) debuted in the 1980s.  3, fiche 2, Anglais, - automated%20insertion%20mount%20machine

One of the major cost savings realized by the roll processors is that the circuit holes can be punched, etched, or laser-drilled prior to metalizing the film. Until recently, it was normal to buy copper clad material only to drill it and have to plate additional copper onto both surfaces in order to get the through-hole connections.  3, fiche 4, Anglais, - circuit%20hole
