| FULLY AUTOMATED
SOLDER SPHERE
PLACEMENT SYSTEM |
In
recognition of the need for a diverse configuration Solder Sphere
Placement System, OnTarget has designed and engineered the "Versatile Process System 6800".
Various system configurations provide out customer the adaptive edge
when encountering the various form factors of the BGA industry.
The VPS6800 is a compact, fully-automated system specifically designed
for the Flux or Paste Print and Placement of Solder Spheres onto
various form factors, such as Strip or Panel substrates. It
additionally supports JEDEC Trays, Boats, and Carriers for singulated
device applications.
The core process method of OnTarget Systems' equipment is the Patented
"Positive Mask Technology", known
for it's repeatability, accuracy, and
robust production worthiness. This process is inherently greater in
performance an capability, as compared to other placement methods, such
as Pin Transfer for Pick & Place.
The system is designed with easily adjustable settings and parameters,
which enable the user greater control over Fluxing and Solder Sphere
Placement, all of which are displayed on an operator friendly Graphical
User Interface.
| DEVICE LOADING AND HANDLING |
BGA Production floor requirements
differ and the VPS6800 addresses this need in its
availability in either Left or Right Hand In-Line conveyor
Feed or with use of modular high capacity Tray Stackers or Magazine
Handlers. Utilizing a back-to-back system configuration and or use of
Lane Changing Handlers, production volume increases can be achieved
trough multiple product streams entering Reflow and yielding greater
UPH processing.
The solder sphere placement
system features
a dedicated flux screen, paste stencil, or rigid flux stencil
which
are compatible with a
number of fluxes/Pb or Pb Free paste. The system includes an automated
flux/paste dispenser with programmable flux feed and low level sensing,
a vision assisted three position micrometer adjustment for
screen/stencil
to device registration, electronically controlled
stroke and speed parameters.
Other key adjustments, such as snap height
and squeegee pressure, give
the user complete control over the entire fluxing process.
Extremely fast repeatable
placement
is achieved by OnTarget Systems' patented solder sphere placement
method and
mechanism that accomplishes simultaneous placement of all spheres on
all
pads of the substrates. An automated ball-feed reservoir eliminates the
interruption of material loading to the system.
Different device configurations are accommodated by modular
sub assemblies of interchangeable tool sets.
A PC running Windows XP®
easily guides the user through set-up,
initialization, operation, error recovery, and diagnostic routines.
From the PC the user may choose one of the three modes of operation:
set-up, run, and diagnostic. Within these modes and at a single
keystroke, the system may be instructed for print only, place only,
print and place, or dry-cycled operation. Set-up adjustment,
controlling
the specifics of the printing and placement process, also may be
preformed directly at this panel. Security lockouts are provided within
the software to prevent any unwanted access.
