Wire-bonding method for wire-bonding apparatus

A wire-bonding method for a wire-bonding apparatus, the wire-bonding apparatus comprising at least a first wire-bonder and a second wire-bonder, for bonding at least a plurality of first chips in a first region and a plurality of second chips in a second region simultaneously, the method comprising:

• (a) obtaining initial position coordinates of the first region and the second region;
• (b) determining whether a space between the first region and the second region is greater than a predetermined space;
• and
• (c) when the space between the first region and the second region is greater than the predetermined space, the first wire-bonder and the second wire-bonder respectively bond the first chips and the second chips simultaneously;
• when the space between the first region and the second region is less than the predetermined space, the second wire-bonder moves away from the first wire-bonder to a third region with a plurality of third chips, the first wire-bonder and the second wire-bonder respectively bond the first chips and the third chips simultaneously.
