Device and method for double-sided precise targeting of HDI (High Density Interconnection) plate

Abstract

The invention discloses a double-sided precise targeting device and method for an HDI plate, and relates to the technical field of double-sided targeting of the HDI plate, the double-sided precise targeting device comprises a workbench, a portal frame fixedly arranged on the workbench, and a limiting plate fixedly arranged on the top surface of a positioning table and located on the front edge of the positioning table; jacking air cylinders fixedly arranged on the positioning table are arranged under the two guide holes, and floating columns slidably installed in the guide holes are fixedly arranged at the acting ends of piston rods of the jacking air cylinders. An automatic feeding device located on the rear side of the positioning table is arranged on the workbench, and material lifting and conveying devices are arranged on the cross beam of the portal frame and located on the left side and the right side of the positioning table. The device has the beneficial effects that the working intensity of workers is relieved, the targeting efficiency of the HDI plate is greatly improved, and the drilling efficiency of the HDI plate is greatly improved.

Description

technical field [0001] The invention relates to the technical field of HDI board double-sided target shooting, in particular to a device and method for double-sided precision shooting of HDI board. Background technique [0002] Electronic component assemblies include single-sided circuit boards, double-sided circuit boards, HDI boards, multi-layer printed circuit boards, printed boards, etc. These electronic component assemblies are the core components of the controller, which can play an important role. Among them, the HDI board is the core component of the vehicle controller. During the production process of the HDI board, multiple blind holes need to be drilled on both the front and the back of the HDI board. [0003] The existing working steps of drilling holes on the HDI board are as follows: the worker first positions the HDI board on the positioning table of the target machine, and then uses the target head of the target machine to hit the target on both the front and...

[0007] III. When the target is finished, the worker directly drags the HDI board away from the positioning platform of the target machine. During the dragging process, the target in contact with the positioning platform is scratched, even if the target is blurred, which leads to subsequent The drilling equipment cannot be positioned according to the fuzzy target, so it can only be shut down again to return the material and shoot again, which undoubtedly further increases the shooting time and further reduces the production efficiency of HDI boards
