3.1.4.1 Description
The PCB conveyor is a single lane conveyor. The machine requires a length of 1100 mm. Both
sides have a 150 mm extension to the upstream or downstream conveyor. The standard conveyor
is a front fixed rail and it only has one lifting table without input/output buffer. A conveyor extension
option exists to increase the length of the single stage conveyor to allow for a barcode capability to
be attached where no upstream conveyor exists.
The conveyor height can be selected on the machine to allow the machines to be integrated into
lines with a conveyor height of, 900, 930 or 950 mm. The standard height is 930 mm.
The communication between the PCB conveyors of the individual machines takes places via the
SMEMA or IPC-HERMES-9852 interface.
3.1.5 Definition of PCB warpage
This is the maximum allowable PCB warpage for the SPI to be able to measure accurately.
3.1.5.1 PCB warpage on the conveyor
PCB warpage across the direction of travel max. 1% of the PCB diagonal, but not exceeding
±5mm.

3.1.5.2 Maximum PCB warpage allowed during processing of the board
There is active PCB warpage measurement and tracking during the inspection so that images re-
main in sharp focus, ensuring best height measurement accuracy on the market.
