The print carriage is a metal frame that is suspended from the top of the machine on four linear
bearings and is responsible for moving certain modules to their required positions in the Y direc-
tion. The carriage is driven by a ball screw connected to a servo motor via a drive belt. The print
carriage frame contains the following:
●
Squeegee Module - to transverse across the stencil in the Y direction (print stroke)
●
Stencil Loading Mechanism - to perform a stencil load
●
Coplanarity Lasers – to transport the auto coplanarity lasers and amplifiers to take measure-
ments from different positions
All positioning of the print carriage is referenced from the home position and calculated in the
machine software, taking into account:
●
Board width
●
Squeegee pitch
●
Hop over distance
●
Front and rear print limits
The print carriage homes during initialisation, which is carried out under the following circum-
stances:
●
At machine power up
●
After the application and recovery of the E Stop
●
When exiting machine diagnostics
