Abstract: A printed circuit board support including a first member having a planar upper surface for supporting a printed circuit board. At least one second member is movably coupled to a first side of the first member and movable toward and away from the side of the movable member, and a bias source biases the second member in a direction away from the first member.

Abstract: A printed circuit board support including a first member having a planar upper surface for supporting a printed circuit board. At least one second member is movably coupled to a first side of the first member and movable toward and away from the side of the movable member, and a bias source biases the second member in a direction away from the first member. The support is readily compressed to allow placement into or onto a space defined by surfaces of a positioning device, and the support expands upon its release to fill the space. When the support is left in the positioning device during a change over to a different circuit board, the support will automatically adjust to any width-wise adjustment in the space between the surfaces of the positioning device.

Abstract: An apparatus for dispensing liquids onto a rotating surface. In one embodiment the apparatus includes one or more dispense lines, each dispense line having a tube and a tubular fitting connected to a nozzle. In another embodiment the apparatus includes a heat exchanger providing circulation of a heat transfer medium between the annular regions defined by the tubes inside the dispense lines through a fluid channel in communication with the annular regions. A method of heating a dispense line. The method includes the steps of flowing a heating medium through the annular region of one dispense line to another through a fluid channel in communicating with the annular regions.

Abstract: An apparatus is disclosed for dispensing liquids on to a rotating surface. The apparatus includes first and second dispense lines connected to at least one liquid source to permit the dispensing of liquids from the first and second dispense lines on to a rotating surface. In a preferred embodiment, the first and second dispense lines are tubular and have first and second dispense tube disposed within the interior region of the first and second dispense lines, respectively. The first and second dispense tubes define first and second annular regions with the dispense lines, which are preferably connected by a fluid channel. A heat exchanger is attached to the first and second annular region to enable a heat transfer medium to be circulated through the first and second annular regions and the fluid channel.

Abstract: An apparatus including a dispense line, a solvent line, and a solvent vapor bath having a purge section is disclosed. The purge section of the apparatus has a cleaning member disposed therein containing at least one dispense hole corresponding to the dispense line. The purge section contains a plurality of ports to receive the dispense line and the solvent line. The solvent line is directed toward the cleaning member when the dispense line extends through the dispense hole. A method of cleaning a dispense line is also disclosed. In the method, a solvent vapor bath comprising a purge region having a cleaning member disposed therein and containing at least one dispense hole is provided. The purge region contains a plurality of ports to receive the dispense line and a solvent line, the solvent line being directed toward the cleaning member when the at least one dispense line extends through the at least one dispense hole.
