VACUUM BOX TOOLING
The vacuum box is manufactured to the same height as the magnetic pins, ie
81mm, irrespective of the thickness of the board being printed. The vacuum
boxes can be constructed without top or bottom plates to allow for additional pin
support of the board. Provision for machining of top plates to accommodate
underside components is available. The box is located on the table by means
of dowels which locate in the two holes on the manual tooling plate.
The minimum length of the vacuum box is 90mm which is dictated by the
locating dowels. Where the board length is less than the vacuum box length,
top plates either side of the board must be used to achieve vacuum.
The following graphic details the dimensional information on the vacuum box
tooling for use on the rising table:

For RTC or Dual Lane machines the vacuum box dimensions, as shown above,
must not be used. Contact ASM Customer support for details of the correct
dimensions to be used.

DEDICATED TOOLING SYSTEM
Chapter Issue 7, Jan 15 Technical Reference Manual 29.5
DEDICATED TOOLING SYSTEM
The dedicated tooling system is a 3-piece construction comprising a plate
assembly which locates on a tooling tower and magnetic support pins that
provide support under the plate assembly when accommodating wide boards.
The system is manufactured to provide board support at the standard tooling
height of 81mm. The plate assembly can be specifically machined to accom-
modate underside components on customers products.
The tooling tower has dowel pin registration and is held in position on the
manual tooling plate by two magnetic clamps located in the vacuum chamber
of the tooling tower. Additional board support can be utilized with the optional
vacuum facility.
