Abstract: A process for the manufacture of a printed circuit board is disclosed in which, during the process, conductive tracks 6 are tested for defects 8 relating to their conductivity and any detected defect 8 is repaired by securing a conductive bridge-piece 9 across the defect 8 by a reflow soldering operation. The repair is encapsulated with a protective layer 16 and the manufacturing process, which includes the further application of heat to the circuit board, is continued.

Abstract: A template for trimming coved linoleum positioned against a wall at a corner to form a symmetrical coved linoleum corner between two linoleum edges wherein the template includes an elongated guide support for clamping a linoleum end, which extends beyond a wall corner, against a wall and the elongated guide support terminates in an end which defines one side of a longitudinal cutting-tool receiving slot at the wall corner, a base plate which is adapted to be placed against the linoleum end which extends beyond the wall corner wherein the base plate terminates in an end which defines the other side of a longitudinal cutting-tool receiving slot and wherein the base plate is joined to the elongated guide support by a fastening means to form an assembly having a cutting-tool receiving slot wherein the slot has a predetermined width and angle relative to the corner and an elongated guide member having a selected length which is secured at one end to the bottom portion of the elongated guide support on the end oppo

Abstract: Calibrating means for a microdispenser of the type wherein a plunger is operable to automatically draw a fixed volume of fluid into, and expel the liquid from, a precision capillary tube. The calibrating means includes a graduation marking on the capillary tube indicating the precise, predetermined quantity of fluid to be drawn into the tube. Calibration is effected by varying the degree of engagement of the microdispenser end cap with the microdispenser barrel, which effects corresponding longitudinal movement of the plunger with respect to the capillary tube until the outer terminal thereof is aligned with the graduation marking on the capillary tube. Friction means are provided for preventing accidental movement of the end cap after the calibration adjustment has been made.
