The position, needing to be pasted, on the ultrathin PCB circuit board can be exposed through the hole, the second positioning hole is matched with the positioning column, and the upper cover of the sheet is inserted into the positioning column; the design of the identification hole is used for identifying the position of the circuit board by the chip mounting device, and when the chip mounting device detects the identification hole, the chip mounting device starts to work.

Above-mentioned technical scheme can see out, the beneficial effects of the utility model are that:

(1) magnetic suction device for SMT (surface mount technology) paster of ultrathin PCB (printed circuit board)

The fixture is carried, the lower cover is limited on the base, after the ultrathin PCB circuit board is placed on the lower cover, the ultrathin PCB circuit board can be prevented from being deviated, the adsorption sheets on the two sides of the upper cover of the thin sheet are tightly attached to the strip-shaped magnetic block on the lower cover, the ultrathin PCB circuit board is completely wrapped and pressed between the upper cover of the thin sheet and the lower cover, the ultrathin PCB circuit board can be prevented from being deformed and warped, and the reject ratio is reduced; the grooves arranged on the two sides of the base can facilitate the placement and the taking out of the ultrathin PCB.

(2) Magnetic suction device for SMT (surface mount technology) paster of ultrathin PCB (printed circuit board)

Carry the tool, the design of reference column can realize fixing a position simultaneously with thin slice upper cover and lower cover, avoids when thin slice upper cover and lower cover are laminating, and upper cover and lower cover counterpoint are inaccurate for thin slice upper cover can't cover ultra-thin PCB circuit board completely.
