The packaging equipment for processing precision semiconductor components, through the cooperation of the feeder and the clamper, supports and clamps the ceramic substrate of the semiconductor components to be packaged, and then sends it to the bottom of the hot pressing aligner to cooperate with the setting of the pre-pressurizer, so that the hot pressing aligner moves down to pre-fix the ceramic substrate, and in the pre-fixing process, the ceramic substrate is aligned to ensure the alignment effect of the substrate. In the process of hot pressing pre-fixing, the resin quickly softens and begins to solidify after being heated, fixes the position of the substrate, prevents displacement in subsequent operations, and thus ensures the accuracy of packaging alignment.
[0018] 2. The packaging equipment for processing precision semiconductor components generates heat through electric heating elements to increase the temperature on the heat-conducting hot pressing elements, uses heat-conducting strips to increase the temperature of the metal base plate, and cooperates with heat-conducting grooves to increase the contact area between the heat-conducting strips and the surrounding air, thereby improving the heat exchange efficiency, so that heat can be transferred from the heat-conducting strips to the metal base plate more quickly. The setting of the heat-conducting grooves can promote the flow of air on the heat-conducting strips, enhance forced convection, and accelerate heat transfer. Furthermore, the pressure applied by the pre-pressurizer can be used to evenly distribute the resin between the two layers of the substrate, share the pressure, reduce stress concentration during the hot pressing process, and improve the bonding strength of the resin after curing, thereby ensuring the packaging quality.
[0019] 3. The packaging equipment for processing precision semiconductor components moves the upper substrate by moving the metal bottom plate downward and coordinating the contact between the bonding alignment plate and the outer side of the substrate, forcing the substrates to align. The resilience of the heat-resistant elastic plate and the hinge of the bonding alignment plate on the hinge seat are used to adjust the alignment range to avoid damage to the substrate caused by excessive downward pressure, significantly improve the alignment accuracy of the two-layer substrate, ensure precise alignment between the substrates, and reduce the risk of poor alignment.
[0020] Fourth, the packaging equipment for processing precision semiconductor components drives the clamping push plate and the bonding plate to move through the cylinder, utilizes the contact between the bonding plate and the side of the substrate to bond with the substrate for rapid positioning, and cooperates with the contact between the straightening roller and the substrate to pull the adjusting part so that the straightening roller has a thrust toward the substrate, assisting the substrate in position adjustment and guiding alignment, thereby further ensuring the packaging quality of semiconductor components.
[0021] 5. The packaging equipment for processing precision semiconductor components, through the contact between the straightening roller and the side of the substrate, causes the alignment plate frame to rotate on the clamping push plate due to the thrust of the contact, pulls the bent push rod to slide in the slide slot seat, and uses the bent push rod to pull the sliding block to slide in the shell, so that the spring is deformed to generate an elastic pulling force, which cooperates with the elastic pulling force of the spring to force the shell and the sliding block to rotate toward the substrate, thereby further ensuring the alignment effect between the substrates, cooperating with the alignment effect of the alignment piece, and improving the alignment accuracy and the quality of semiconductor component packaging.
