Why Do I Need an Underside Board Support
System?
Small, thin epoxy/glass substrates tend to "sag"
during the mass heating (reflow) process due to progressive
resin softening. In certain cases, this can result in
board dropping. This problem is most prevalent on multi-panel
assemblies that are 0.020 to 0.031 inches/0.5 to 0.8 mm
thick and greater than 7 inches/178 mm in width. If your
boards fit this description, then Conceptronics
Single or Multi-Cable PCB Support Options may be ideal
for you.
Why a Cable-Based Board Support System?
Traditional center support systems use special chains
that "ride" on top of long, thin metal carrier
rails. Due to their small form-factor and high operating
temperatures, these long rails are prone to sagging, twisting,
and warping. In addition, the transport chain is difficult
to remove. As a result, positional accuracy and processing
flexibility is limited. In contrast, our unique design
incorporates a tensioned cable and special sectional supports.
Thus, greater positional stability and accuracy are provided.
This system is also thermally "invisible" to
the process.
Fully Removable for Alternate Double-Sided
PCB Processing
Unlike chain-based support systems, our cables continuously
recirculate within the processing chamber at the same
speed as the edge conveyor. This arrangement enables quick
removal and replacement of cables (in minutes). It also
enables the complete support assembly to be "tucked"
under edge conveyor extrusions for maximum underside chamber
clearance. And, with no chain, NO OILING IS REQUIRED!
"No-clean" assemblies can never be contaminated.
Who Can Best Use This Technology?
Cable-based underside board support technology is ideal
for both the dedicated high-volume manufacturer and the
low-volume prototype manufacturer who deals with thin,
low-mass multi-up panels. It is available in single or
multi-cable configurations.
