Abstract
The invention relates to a measurement apparatus for depths of blind holes and countersinks of a high density laminated plate. A dial plate of a dial gauge is embedded in a circular hole manufactured in a support and matched with the dial plate. A shaft sleeve and a mandrel at the lower end of the dial plate are positioned in a gap produced in the lower end of the support. The lower end surface of the support is used for being connected on the surface of a circuit board through pressure welding. The lower end portion of the mandrel is provided with a vertically-downward hole gauge in a servo-actuated mode through a fixing device. The lower end portion of the hole gauge can extend into a blind hole or an countersink manufactured in the circuit board at the lower end of the support. The external diameter of the hole gauge is the same with the internal diameter of the blind hole or the countersink. In the invention, the hole gauge extends into the blind hole or the countersink; displacement of the hole gauge is transmitted into the dial plate to enable a pointer to change; and a measurement person directly reads reading of the pointer to obtain the depth of the blind hole or the countersink. The measurement process is simple; the result is accurate; the working efficiency is high; and the measurement process will not destroy the circuit board.
