Description

Technical Field

[0001] The invention relates to the technical field of semiconductor packaging, and in particular to an adaptable and adjustable preheating plate for semiconductor packaging. Background Art

[0002] Semiconductors need to be plastic-sealed during production, and an automatic film arrangement machine is required for plastic sealing. The automatic film arrangement machine is equipped with a preheating plate, which is installed on the loading rack of the automatic film arrangement machine. The preheating plate preheats the product frame, and the loading arm structure drives the product frame to move and arranges the product frame into the preheating plate.
