Xcs Edge Rail With Extruded Center Support System - Vitronics Soltec XPM2 Technical Reference Manual

XCS EDGE RAIL WITH EXTRUDED CENTER SUPPORT SYSTEM
The eXtruded Center Support system consists of an additional rail extrusion and a special XCS chain with
extended side plates that supports the middle of the PCB to prevent warping. The XCS plates extend to the same
height as the top of the edge rail chain pins where the PCB sits. The XCS chain can be parked between the
conveyor pins on the fixed rail chain, enabling the user to move the system out of the process lane when not
required. After a period of time both the conveyor chains and the XCS chain will stretch, and it may not be
possible to park the XCS between the fixed rail pins. When this happens, the fixed edge rail chain and the XCS
chain must be replaced as a matched set.
This option is available with both manual and automatic positioning. When automatic positioning is specified both
the edge rail and XCS rails are computer controlled.
XCS system general specifications:
Chain - Fixed Edge Rail
Chain - Moveable Edge Rail
Chain - XCS
Edge Rail parallel
XCS Chain Plate Height
XCS Chain Plate Width
XCS rail to fixed rail parallel
XCS height to edge rail
XCS chain plate tracking
XCS plate height variation
XCS park position
Auto Rail repeatability
Auto Rail set point accuracy
* After extended service the XCS and edge rail chains may wear at different rates and this can affect their pitch
match. If excessive mismatch develops it may no longer be possible to park the XCS between the edge rail pins.
