The Multiframe is a complete draw replacement style of frame
that easily adapts to existing exposure units. Designed and manufactured
by Multiline Technology in the United States, this new phototool offers
the highest accuracy (± 0.0004") (± 10 µm) in front
to back registration for photo imaging of double sided Printed Wiring
Boards and/or Multilayers. Depending on the tooling system this one frame
can accommodate multiple panel sizes and thicknesses, as well as processing
innerlayers and outerlayers without the need to change the glass.
Unlike typical glass phototools the Multiframe incorporates many
new innovative features. A feature that our customers have expressed excitement
about is the "Spring Loaded Pneumatically Retracted Pin System". This
unique patented pinning system has been developed to ease the removal
of boards (laminated panels) from the tooling pins after exposure. The
pneumatically activated pins are drawn out of the tooling holes by a pneumatic
switch located on the front of the unit. This new pinning system eliminates
prying of boards (laminated panels) from tooling that can cause damage
to the film and the glass.
When is comes to registration, the Multiframe offers a one of
a kind Three-Point Centerline Alignment system. Precision top to bottom
glass registration is achieved by registering the floating top glass to
the bottom glass, by using 3 precision pins that self align to tapered
slots.
A new technologically advanced UV resistant gasket gives this new phototool
flexibility like no others. It automatically adjusts to different panel
thickness ranging from (0 to .1575") (4mm). Without the loss of chamber
vacuum and the need to shim or change over too new seals or hinges.
The Multiframe comes standard with heat strengthened glass and
includes a tool free change over system, which is only offered by Multiline
Technology. This quick-change operation is effortless thus, giving the
operator the ability to change the glass and tooling in minutes.
High productivity and fast setup are common comments from our customers.
This is possible because taping and gluing film is a thing of the past.
Films are held in the top and bottom glass of the Multiframe with
an integrated vacuum system.
Clean room safe bearings are utilized throughout the Multiframe.
Multiline has chosen these bearings because many of our customers expressed
concerns about unwanted metal shavings appearing in exposed films after
prolonged usage. These metal shavings can sometimes get in between panels
and films, which can cause havoc in the quality of your production. Using
a Multiframe produces 100% accuracy and dependable registration
with no metal shavings.
The Multiframe is a complete drawer replacement style of phototool
with interchangeable glass that easily adapts to existing exposure units.
This unit can be utilized for inner/outerlayers as well as solder mask.
