Description

Automatic adjusting type vacuum suction device

Technical Field

The utility model relates to a on Printed Circuit Board (PCB) circuit etching process's the full-automatic horizontal vacuum etching machine of production facility, concretely relates to automatically regulated formula vacuum suction device.

Background

In the PCB manufacturing industry, with the demands of light weight, thinness, short length, small size, quickness, multiple functions and integration of circuit boards, HDI high-density interconnection PCB boards are popular in the world, and 2mil/2mil lines are about to be popularized on the PCB boards. The presence of water accumulated in the middle of the board surface on the conventional horizontal line makes the etching rate in the center of the board significantly slower than that of the four sides of the board, and more significant than that of the head part of the board, which is the so-called "pool effect", greatly hinders the development of the PCB upper and lower board surfaces to 2mil/2mil or thinner lines at the same time. In order to solve the problem, a first-generation horizontal vacuum etching machine is developed, wherein a first-generation vacuum etching suction device is arranged on a roller shaft, and the suction device and the roller shaft are connected together, so that the suction device can automatically lift and fall within a small range (generally within 0.05-3.2 mm) along with the roller rolling to a PCB with a certain thickness, and the distance between the suction device and the PCB is kept. However, with the high integration of new energy vehicles and 5G communication backplanes, the thickness range of a large number of high-end PCB circuit boards is greatly increased to 0.035-12 mm, the suction device of the first generation horizontal vacuum etching machine cannot adapt to a wider application range, and the suction device and the roller shaft are connected to be pressed on a precise PCB fine circuit through the roller, so that the roller is easy to damage the outline of the fine circuit. For IC carrier boards required by ultra-fine circuits and coming 5G era with high frequency and high speed, the tiny loss on the PCB circuit will cause great influence on the transmission of 5G communication signals and automatically driven millimeter wave radar signals, and must be effectively improved.
