This　paper　presents　an　optimization　study　of　dual-gantry　high-speed　rotary-type　pick-and-place　surface　mount　device　(SMD)　machine.　In　the　dual-gantry　SMD　machine,　there　are　two　feeder　bases　and　gantry　heads,　such　that　two　placement　heads　can　pick-and-　place　synchronously　in　one　PCB,　which　has　an　advantage　in　assembly　PCB　with　more　component　types.　The　dual-gantry　optimization　problem　is　decomposed　into　nozzle　arrangement,　feeder　assignment,　pick-and-place　sequence,　component　allocation,　and　gantry　schedule　problems.　To　balance　the　workload　between　gantries　and　reduce　the　wait　time　in　the　gantry＇s　synchronous　movement,　a　balanced　adaptive　tabu　search　(BATS)　algorithm　is　proposed.　Based　on　the　16　industrial　data　tests,　the　proposed　algorithm　yields　a　7.04%　improvement　on　average　compared　to　the　industrial　package.　(c)　2017　The　Authors.　Published　by　Elsevier　B.V.
