Manncorp's BR790-HD rework system
allows operators to safely remove, align, place and solder BGAs, CSPs,
ultra-fine-pitch QFPs, and other delicate, heat-sensitive SMDs with
unprecedented ease and precision.
Manncorp BR790-HD's High-Definition Optics and Real-Time Temperature Profiling Conquer SMD Rework's Most Challenging Tasks
The
BR790-HD's
1.3 million pixel, split-vision optics and 15" high-resolution display
make fast, accurate work of component alignment via crystal-clear,
superimposed images of leads and solder pads. A handy component
presentation nest, mounted to the optics’ X and Y drives, automates
pickup and positioning of the component in the camera’s field of view
and reduces handling of delicate SMDs.
Five separate input
connectors allow strategic positioning of K-type thermocouples at
critical locations on the component and PCB. An easy-to-use LCD
touchscreen interface displays real-time temperatures and allows
on-the-fly adjustment of top and bottom hot air heater settings for
ultra-precise profiling. Screen captures of process profiles can be
saved to an external USB flash or hard drive for traceability.
PCB positioning is easy, thanks to the BR790-HD's unique, edge-clamping
system, which easily adjusts to fit boards up to 21.6" x 19.7" (550 x
500 mm). During setup, an innovative laser guide allows trouble-free
alignment of the rework site with the system's top- and bottom-side
heater nozzles.
For alignment of components to solder pads, the
board holder includes ultra-fine micrometer adjustments of the X and Y
axes. Correction of angular alignment is performed by rotating the
pickup head’s motorized theta axis through the touchscreen interface or
via a manual override on the head. During automatic component removal
and placement, an optoelectronic sensor controls Z-axis positioning and
contact force.
The BR790-HD's programmable 6-zone "Rapid IR"
underheater evenly heats the bottom of the board, eliminating thermal
gradients and stress on components and solder joints adjacent to the
rework site. Capable of supplying up to 3600 watts of heating power, it
also reduces overall cycle times and maximum temperature exposure.
Built-in cooling fans blow ambient air across the PCB at the end of the
cycle.
The
BR790-HD BGA rework station
is well suited for use with virtually any rework application. Its short
learning curve and user-friendly design puts precision rework in the
hands of even inexperienced operators. Visit
