A printing fixture for smt double-sided patch components

Abstract

The invention discloses a printing fixture for SMT double-sided patch components, which comprises a seat plate, four corners of the lower end of the seat plate are fixedly connected with feet, the lower ends of the feet are all bonded with anti-slip pads, and four corners of the upper end of the seat plate are The same installation frame is fixedly connected through the support rod, and a through groove is opened in the middle of the installation frame, and a support mechanism is installed inside the through groove, and a number of first screw holes are opened through the side wall of the installation frame. A first screw rod with a first extrusion head and a second screw rod with a second extrusion head are arranged on the installation frame, and the circuit board is fixed on the installation frame by using the first extrusion head and the second extrusion head. frame, when fixing a larger or smaller circuit board, only need to change the connection position of the first screw and the second screw, and change to other suitable first screw respectively. hole and the second screw hole, without the need for a whole replacement, more convenient, and lower manufacturing cost.

Description

Technical field [0001] The present invention relates to a printing fixture, and more particularly to a SMT double-sided patch component printing fixture, which belongs to the technical field of printing fixtures. Background technique [0002] Surface assembly technology (SMT) is also known as surface mounting and surface mounting techniques, is a circuit assembly technique for mounting unparalleled or short-lead surface assembly by reflow or immersion welding. The printing fixture is one of the mechanical devices used during printing. [0003] At present, the printing fixture used by the SMT patch can only fix the size of the circuit board, and the corresponding printing fixture needs to be replaced when fixed the large or smaller circuit board, and more troublesome, and need to manufacture multiple printing fixtures. When the manufacturing cost is high, and when fixed, the lower end of the circuit board is mostly directly contact with the surface of the fixture, and the lower en...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a printing jig for SMT double-sided patch components, which effectively solves the problem that most of the printing jigs used for SMT patching can only fix circuit boards with similar sizes. When fixing circuit boards with larger or smaller volumes It is more troublesome to replace the corresponding printing jigs, and it is necessary to manufacture multiple printing jigs, the manufacturing cost is high, and when fixing, the lower end of the circuit board is mostly in direct contact with the surface of the jig, and it is easy to damage the lower end of the circuit board when fixing The problem
