Harmomegathus difference-resistant plate fixing device for sheet manufactured by gantry electrofacing

Abstract

The invention relates to a harmomegathus difference-resistant plate fixing device for a sheet manufactured by gantry electrofacing. According to the technical scheme, the device comprises rack top plates, rack side plates, a rack base plate, an upper grip, a puller bolt and a connection plate, wherein two ends of the rack base plate is fixedly provided with the rack side plates; the top end of the rack side plate is connected on the rack top plate; the upper grip is arranged on the rack top plate; the rack base plate is provided with the puller bolt; the upper surface of the rack base plate is provided with a base plate card slot; and the top end of the connection plate is connected with the rack top plate, and the bottom end of the connection plate is connected with the rack base plate. The invention overcomes the harmomegathus difference of the sheet caused by gravity and torque of the rack, meets the fixing requirements of electrofacing sheets of different sizes, and the light, thin and accurate fixing requirements of the future electrofacing sheets, and has the advantages of simple structure, convenient operation and the like.

Description

technical field [0001] The invention relates to a gantry-type electroplating plate fixing device for preventing expansion and contraction differences of thin plates, which belongs to the technical field of printed circuit boards. Background technique [0002] In the existing PCB technology, the electroplating method of thin plates (thickness ≤ 0.2mm) is carried out through horizontal electroplating lines; due to the high cost of horizontal electroplating lines; general PCB factories still use gantry-type vertical electroplating lines to make thin plates , In addition, use a thin plate hanger, and fix it by tightening the four corners of the plate end with screws. In this method, the thin plate is easily deformed by the screw torque to cause a large deformation of the plate corners, resulting in a large expansion and contraction and a large difference in expansion and contraction. [0003] In the future PCB trend, thinner substrates will be used to meet the "light", "thin" an...

[0002] In the existing PCB technology, the electroplating method of thin plates (thickness ≤ 0.2mm) is carried out through horizontal electroplating lines; due to the high cost of horizontal electroplating lines; general PCB factories still use gantry-type vertical electroplating lines to make thin plates , and use a thin plate hanger, and fix it by tightening the four corners of the plate end with screws. In this method, the thin plate is easily deformed by the screw torque to cause a large deformation of the plate angle, resulting in a large expansion and contraction and a large difference in expansion and contraction.
