3.7.4 IPC-Hermes-9852
IPC-HERMES-9852 is a communication protocol for SMT lines and can replace the IPC SMEMA
interface. This protocol allows you to transfer more information than previously via the IPC
SMEMA interface. This could be, for example:
– Unique board IDs
– Barcodes
– Conveyor speed,
– Board length and width
– Board thickness
– Transport clearance height
All this information can be transmitted along the whole line without interruption. See also the ad-
ministrator manual IPC-HERMES-9852, [item no.: 00198615-xx]

3.7.5 Definition of PCB warpage
3.7.5.1 PCB warpage on the conveyor
PCB warpage across the direction of travel max. 1 % of the PCB diagonal, but not exceeding 2
mm.

PCB warpage in the direction of transport + PCB thickness < 5.5 mm. Bending up of board edge
max. 2.5 mm.

3.7.5.2 PCB warpage during placement
3
3
Changes in the surface position are automatically applied by the functions for learning the height.

3
PCB warpage up, max. 2.5 mm
PCB warpage down, max. 2.5 mm
PCB support
To avoid impairing the placement quality and speed, we recommend using a PCB support e.g.
Smart Pin Support so that the PCB warpage downwards does not exceed 0.5 mm.
