Main improvement – Head
Improvement of placement
precision by recognizing
simultaneously with reference
mark when recognizing parts.
Individual camera is directly
assembled to the head main
frame.
Placement view obtained
from front by arranging the
fly camera with inclination
Cost reduction by removing
the ascending/descending
part of side illumination
Prevention of board damage by external
force resulted from separation of head
related board and instruments.
Improvement of grease
application to X driving part
Sol block’s arrangement in the rear to obtain
minimum space for 2-gantry approach

Head mechanism modification for Max □ 42mm , Thickness 12mm component
SM411F has several changed parts In comparison with SM411
(SM411F)
to avoid the interference
between a component and mirror
Main improvement – X-Y
The assembly precision is
improved by obtaining
concentricity of X-motor and
b/screw.
Improved assembling ability by pin
assembly of X-Y assy. (Assembly
clearance by processing is obtained)
To prevent modification after assembling
in module unit, the structure is improved to
simply assemble Y-b/screw after
assembling X-Y body.
Improvement of grease application
method to Y driving part
(The difficulty of approach is solved
when applying grease to 2-gantry)

z Structure
• ENTRY SHUTTLE ASSY : Composed of front and rear moving rail. Performs width trimming and shuttle
movement with one ball screw and two motors.
• WORK ZONE ASSY : Composed of front and rear placement zone. Performs width trimming with lead
screw and motor and performs PCB settling function in relation with BUT.
• EXIT SHUTTLE ASSY : Composed of front and rear moving rail. Performs width trimming and shuttle
movement with one ball screw and two motors.
• Composed of dump box and cable wiring related parts.
