Abstract: An apparatus for trimming the wire leads of electronic components mounted on printed circuit boards is provided, which comprises a base plate, an adjustable holding fixture for a printed circuit board fixedly disposed on the base plate, a pivotable cantilevered bracket assembly mounted on the base plate adjacent the holding fixture, a motor-driven rotary cutting blade disposed on the end of the cantilevered pivotally movable bracket assembly for movement along the surface of a printed circuit board disposed within the holding fixture, and an anti-warp device including one or more pivotable lever arms disposed above and below the printed circuit board, and an adjustable pin mounted on each of the upper lever arm to engage the top surface of said printed circuit board and urge the same into a flattened position and an adjustable pin disposed in each of the lower lever arms to engage the bottom surface of said printed circuit board to urge the same in a flattened position.

Abstract: Tacky portions of the surface of a photopolymer article, such as a photopolymer printing plate, are treated by immersing the photopolymer article in an aqueous solution of bromine and circulating the solution across the photopolymer article and through an ion-exchange resin to which elemental bromine has been added.
