    摘要: A tool for soldering pin-in-hole electronic circuit components includes a tool plate (10) with a set of holes (15) corresponding to the vias of a circuit board on which a circuit component is to be soldered. The board is aligned with the tool plate and hot gas is supplied through the set of holes to reflow solder in the vias. The tool is particularly suitable for use in removing a replacing circuit components. Use of particular gases allows soldering to be carried out without use of flux. Advantages of the tool are that it prevents burning the circuit board and/or unintentionally reflowing other circuit components mounted on the board.

    摘要: A method and apparatus for cleaning workpieces (16), particularly printed circuit boards upon which electrical components have been soldered, is capable of using a potentially flammable or explosive liquid cleaning solvent. In one embodiment, there are two immersion wash stages between which is a spray wash stage. The spray wash stage is formed as a closed chamber (28) which is sealed from the immersion wash stages by liquid seals (18,30). To reduce the danger of fire or explosion in the spray wash stage an inert gas such as Nitrogen is introduced into the closed chamber (28). In another embodiment the spray nozzles (3) are immersed in liquid solvent in a combined immersion/spray wash stage. This reduces atomization of the flammable solvent further reducing the danger of fire or explosion.
