Problems solved by technology

[0004] The lead frame surface treatment device in the prior art mostly uses soaking and spraying to treat the surface of the lead frame. In the process, impurities are easy to stick to the surface of the lead frame, which is not conducive to subsequent processing. In view of this, we propose a surface treatment device for integrated circuit lead frames

Abstract

The invention relates to the technical field of lead frame surface treatment, in particular to an integrated circuit lead frame surface treatment device which comprises a shell, and spray washing mechanisms used for conducting spray washing on the surface of a lead frame are symmetrically arranged on the two sides of the shell. A conveying mechanism used for clamping a lead frame to move in the shell is arranged on the inner wall of the shell, a guide plate is fixed to the inner wall of the shell, the top face of the guide plate is inclined, a communicating groove is formed in the position, located at the lowest position of the guide plate, of the shell, and a draining box is fixed to the outer wall of the shell and communicates with the interior of the shell through the communicating groove. A filter opening is formed in the top surface of the guide plate close to the draining box, and a first filter screen is fixed in the filter opening; according to the scheme, liquid medicine is sprayed to the lead frame through the spray-washing mechanism, and the liquid medicine is filtered in time, so that impurities are prevented from adhering to the surface of the lead frame, and subsequent processing of the lead frame is facilitated.

Description

technical field [0001] The invention relates to the field of surface treatment of lead frames, in particular to a surface treatment device for integrated circuit lead frames. Background technique [0002] As the chip carrier of integrated circuits, the lead frame is a key structural part that realizes the electrical connection between the lead-out end of the chip's internal circuit and the outer lead by means of bonding materials (gold wire, aluminum wire, copper wire) to form an electrical circuit. When it comes to the bridge function of connecting with external wires, most semiconductor integrated blocks need to use lead frames, which are important basic materials in the electronic information industry. [0003] Some invention patents related to the surface treatment of lead frames have been disclosed in the prior art. The Chinese patent application number is 201711365801.8, which discloses a device for surface treatment of lead frames, including a feeding mechanism, a rec...
