Description

Contact Electronic Inspection Module

technical field

The invention relates to a contact electronic inspection module, in particular to a contact electronic inspection module used in contact integrated circuit (IC) and other electronic product inspection equipment.

Background technique

When the general integrated circuit (IC) and other electronic products are manufactured, they must go through multiple inspections to ensure the yield rate of the products. The existing inspection methods for integrated circuits (IC) and other electronic products are mainly divided into two types: non-contact inspection and contact inspection. Non-contact inspection uses optical equipment inspection, and contact inspection uses integrated circuits or other electronic products. The product is placed on the testing device, and the probes (terminals) of the testing device are in contact with the contacts of integrated circuits or other electronic products, so as to obtain inspection data to verify its quality.

In order to make the contact inspection equipment adaptable to various integrated circuits (IC) and other electronic products, related companies propose a contact inspection device (module).

Although the upper end 501 of this metal probe 50 is not easy to be worn out, and may be replaceable, the elastic coefficient of the metal probe 50 is insufficient or the structure design is poor, and it is easy to wear and tear the contact of the integrated circuit or other electronic products (for example, for wear and tear). To enhance the conductivity of the plating), and even damage the contacts of integrated circuits. It can be seen that the existing contact detection devices used in integrated circuits and other electronic products have many defects that need to be improved urgently.
