20230086461 · 2023-03-23 ·

Proposed is a method for controlling a boat carrier/substrate strip type solder ball placement system that allows solder ball mounting processes for a boat carrier type of a material and a substrate strip type of a material to be all performed in one system. In specific, the method allows the components or operation setting of the system to be automatically controlled according to the types of materials loaded on a magazine, thereby performing solder ball mounting processes for the two types of materials with high speed and high accuracy. In more specific, the method allows a component applied only to the solder ball mounting process for the boat carrier type of material and a component applied to the solder ball mounting process for the substrate strip type of material to be integrated with each other as a single component in the process of mounting the solder balls on the material on-loaded, thereby making it possible to perform the solder ball mounting processes for the two different types of materials in one system.
