Abstract
Disclosed are a potting system used in a semiconductor chip packaging process and a cured resin discharge amount inspecting device employed therein. Curing resin discharge amount inspection device is composed of a guide rail and a weight scale. The guide rail extends along the arrangement direction of the potting heads, and the weight scale is installed to be movable along the guide rail. Since the discharge amount of the cured resin discharged from the potting head in the potting system can be quickly measured, the time required for the discharge amount inspection can be reduced and the productivity can be improved.
Description
The present invention relates to a potting system used in a semiconductor chip packaging process, and an inspection apparatus for inspecting the amount of hard resin discharge of the potting head employed in the potting system.
Semiconductor chips fabricated on wafers are mass-produced as individual chip products through separate packaging processes. The packaging process is carried out through Dicing- ILB-POT-Marking process, and the manufactured chip is inspected through FT (Final Test) process and VI (Visual Inspection) process.
Dicing (SAW) is a process of dividing a number of chips patterned on a wafer into individual chips to form a single product. In the ILB process, the bumps of the completed chip and the inner lead on the film are bonded by thermo-compression using high temperature heat and pressure to form an electrical path to the outside. It is a process. POT process is based on epoxy resin in liquid state to protect the circuit part of chip including ILB process from external physical, chemical, mechanical and electrostatic environment to ensure product reliability. It is a process of applying and sealing a sealing material with a dispenser. Marking process is a process of stamping the serial number of each product by printing the coded information of the product on the surface of the product.

The present invention has been made to solve the above problems, an object of the present invention is to reduce the amount of time due to the discharge amount inspection to improve the productivity by enabling to quickly measure the discharge amount of the cured resin discharged from the potting head in the potting system To make it possible.
Curing resin discharge amount inspection apparatus according to the present invention for achieving the above object, a guide rail disposed adjacent to a plurality of potting heads in the potting system, extending along the placement direction of the potting heads; And a weight scale installed to be movable along the guide rail, the weight scale measuring the weight of the cured resin discharged from each of the potting heads.
It is preferable to include a; moving means for moving the weight scale along the guide rail. The moving means, the ball screw disposed along the guide rail; And a moving member fixed to the weight scale and moved along the guide rail by the rotation of the ball screw. The moving means may further include a motor for rotating the ball screw.
On the other hand, according to this invention, the potting system provided with the cured resin discharge amount inspection apparatus which has such a structure is provided.
According to the present invention, since the discharge amount of the cured resin discharged from the potting head in the potting system can be measured quickly, the time according to the discharge amount inspection can be reduced and productivity can be improved.
