A method and system for coating glue and solidifying crystal

Abstract

The invention discloses a glue coating crystal solidifying method and a glue coating crystal solidifying system. The method comprises the following steps that A, crystal grains on a wafer disc are picked through a crystal solidifying arm; B, the bottoms of the picked crystal grains are immersed into a glue disc to be coated with glue water to be subjected to gluing treatment; C, the crystal grains subjected to the gluing treatment are bonded and welded on positions requiring crystal solidification on the carrier. One machine and control structure is adopted for crystal picking, and in addition, the glue taking is realized through wafers per se, so adverse phenomena that in the traditional mode, the blind points exist in bonding positions of the crystal grains and the glue points, the bonding surface distribution is nonuniform, the deviation of the crystal grains and the glue drip reset points is greater, the glue form is not full, the absorption firmness is poor, and the like can be avoided. The crystal solidifying method can be realized through adopting the independent system, the problem of collision when two independent mechanisms are used for production in the same station can be completely avoided, the mechanical structure is simplified, the control difficulty is reduced, and meanwhile, the product precision is also improved.

Description

technical field [0001] The invention relates to the field of semiconductor precision manufacturing and equipment, in particular to a glue-covered crystal-bonding method and system for IC and LED semiconductor packaging. Background technique [0002] The purpose of solid crystal is to fix the crystal grain (or chip) on the carrier, so that the input of thermal or electrical signal can be realized between the crystal grain (or chip) and the carrier. Whether the position of the grain (or chip) placed in the carrier package is accurate or not directly affects the luminous and conductive performance of the device. If the position of the grain (or chip) in the carrier package deviates, the light will not be fully emitted in the lighting device As a result, the brightness of the finished product will be affected, and in the integrated circuit, the electrical signal will not be fully connected, which will affect the efficacy of the finished product. Therefore, the precision of the ...
