CONVEYOR OVERVIEW
CONVEYOR TYPES
This Section describes the five types of conveyor transport systems available on the Vitronics-Soltec Reflow
Ovens. They are:
1) Belt-Only Mesh Belt Conveyor System.
2) Rail-Only Edge Rail Conveyor System.
3) Combo Edge Rail and Belt Conveyor System
4) XCS Edge Rail System with Extruded Center Support
5) MBS Combination Edge Rail and Belt System with Metal Band Support
The Mesh Belt system is base standard conveyor on Vitronics-Soltec Reflow Ovens. The Rail-Only, Combo,
XCS, or MBS Conveyor Systems are offered on new ovens by special order.
BELT-ONLY MESH BELT CONVEYOR SYSTEM
The mesh belt conveyor system is used to process single sided surface mount printed circuit boards.

RAIL-ONLY EDGE / RAIL CONVEYOR SYSTEM
The edge / rail conveyor system (shown below) permits single or double sided surface mount printed circuit boards
to be processed through the oven. The standard chain conveyor carries circuit boards on 0.185 inch (4.75mm)
long pins extending from the chains. This conveyor system provides a convenient interface to other equipment in
the production line. Some Ovens have two sets of rails and chains (Dual Rail) for the processing of two PCBs at
the same time.

Edge Conveyor Rails
Edge / rail conveyor system.
COMBO COMBINATION CONVEYOR SYSTEM
The combination belt/rail conveyor has both the edge rail and a mesh belt. The mesh belt is approximately 7/8
(22mm) below the edge rail conveyor, and both conveyors are driven together. The belt conveyor is shorter than
the outside edge of the machine with the sheet metal covers on, and shorter than the end of the rails with chain
guards installed.
Approximately 3 inches between end
of belt and end of rail conveyor (both
ends).
