The invention relates to a fine adjustment device for a fixture of a test machine for a printed circuit board. The fine adjustment device comprises a base plate, a left-to-right movable plate and an inside-to-outside movable plate, wherein the left-to-right movable plate is arranged on the base plate; the inside-to-outside movable plate is arranged on the left-to-right movable plate; a left-to-right movement adjusting mechanism is arranged between the base plate and the left-to-right movable plate; and an inside-to-outside movement adjusting mechanism is arranged between the left-to-right movable plate and the inside-to-outside movable plate. The fine adjustment device for the fixture of the test machine for the printed circuit board is simple in structure and low in manufacturing cost; and with the adoption of the fine adjustment device, production time can be saved, on-line cost is reduced, difficulty in adjustment of the fixture by staffs is reduced, damage of the fixture during the production progress is improved effectively, and maintenance cost on the fixture is lowered.
Description
technical field [0001] The invention relates to the offset adjustment of an electrical testing machine used in the PCB industry, in particular to a fine-tuning device for a testing machine jig for a printed circuit board. Background technique [0002] Printed circuit board Printed circuit board (hereinafter referred to as PCB), the development of PCB in my country began in 1956, and gradually expanded to form the PCB industry from 1963 to 1978. More than 20 years after the reform and opening up, due to the introduction of foreign advanced technology and equipment, single-sided, double-sided and multi-layer boards have achieved rapid development, and the domestic PCB industry has gradually developed from small to large. Due to the concentration of downstream industries and the relatively low cost of labor and land, China has become the region with the strongest development momentum. In 2002, it became the third largest PCB output country. In 2003, PCB output value and impor...
