Working platform of plate passive surface acoustic wave filter

Abstract

The invention provides a working platform of a plate passive surface acoustic wave filter. The working platform does not need a traditional clamp to fix and locate a product any more, can meet the fixation requirements of products of different sizes, saves time and maintenance cost, and can further ensure wire bonding quality. The working platform of the plate passive surface acoustic wave filter comprises the working platform and a carrying plate, wherein the working platform is connected with a control system of a wire bonder; the control system comprises a clamp signal interface, a vacuum interface and a wire feeding fault signal interface; a left slide conveying trough and a right slide conveying trough are formed on the working platform respectively; and the carrying slide body comprises two rows of corresponding product troughs. The working platform of the plate passive surface acoustic wave filter is characterized in that two notch are further formed on the upper surface of the working platform; a blind hole channel is formed inside the working platform body and is communicated with each of the two notches; the open end of the blind hole channel is connected to a vacuum tube; the vacuum tube is connected with an electromagnetic valve, and the electromagnetic valve is connected with the control system and the clamp signal interface.

Description

technical field [0001] The invention relates to equipment used in the wire bonding process flow of chips in the fields of communication and electronics, in particular to a chip-type passive surface acoustic filter working platform. Background technique [0002] In the chip passive surface acoustic filter production process, after the chip completes the front-end processes such as circuit deposition and exposure, it still needs to go through ceramic packaging processes such as slicing, die bonding, wire bonding, spot welding, and seam welding. During the process, the slides are placed on the working platform, how to effectively fix the products on the slides has always been the key to the quality. At present, the traditional method is to use fixtures to fix products to ensure the normal process of welding wires, but fixing with fixtures has the following disadvantages: 1. According to market demand, products are becoming more and more diverse in size, and products of differen...

At present, the traditional method is to use fixtures to fix products to ensure the normal process of welding wires, but fixing with fixtures has the following disadvantages: 1. According to market demand, products are becoming more and more diverse in size, and products of different sizes need to be matched with different It takes a lot of time to fix the fixture; 2. The traditional fixture also needs to spend a lot of manpower, material resources and time for maintenance and maintenance to ensure its service life; 3. The use of traditional fixtures is easy to cause potential welding wire quality due to fixing problems problems, such as line collapse
