Embodiment Construction

[0014] Below in conjunction with accompanying drawing, the present invention will be further described:

[0015] A processing technology for a pin base, which is characterized in that it includes the following steps: 1) blanking, 2) processing holes that require anodizing treatment, 3) anodizing treatment, 4) heat treatment for stress relief, 5) precision of external dimensions Processing, 7) Local anodizing; protect all areas except the four sides of the pin base with protective tape or paint or foil tape. The blanking refers to reserving a machining allowance at the length, width, and thickness of the pin base, and reserving a large amount of machining allowance at the length and width, and forming reinforcing ribs around the pin base. effect. The above processing requires anodized holes, first process the thickness to the size of the drawing; then process the positioning holes 1 on the pin base and all the internal pin mounting holes 2 that require anodized treatment, the ...

Abstract

The invention discloses a processing process of a pin base. The processing process comprises the following steps of: (1) discharging; (2) processing holes needing anodic oxidation treatment; (3) carrying out anodic oxidation treatment; (4) carrying out distressing heat treatment; (5) carrying out fine processing on the overall dimension; (6) carrying out protection; and (7) carrying out local anodic oxidation. The processing process disclosed by the invention has the advantages that the processing accuracy of the pin base can be ensured, the deformation caused by the anodic oxidation treatment is reduced, and the installation of a chip pin on the pin base is convenient.

Description

technical field [0001] The invention relates to the field of aluminum alloy chip packaging and testing equipment, in particular to a processing technology of a lead base. Background technique [0002] In the field of chip packaging and testing using aluminum alloy materials as the manufacturing base material of testing equipment, by anodizing the part or the whole of the aluminum alloy product, the good conductivity of the aluminum alloy itself and the insulation of aluminum oxide are used to realize the test process. requirements for device functionality. It avoids the loss of test frequency caused by inserting conductive leads on the plastic substrate in the past, and realizes a more accurate test of chip operating frequency. But at the same time, limited by the size of the chip, the pin base, which is usually used to carry and position the chip to be tested, has the structural characteristics of small size, thin thickness and small holes all over it. The anodic oxidatio...
