31. Selecting Start Purge starts the purge routine. Adhesive is delivered onto
the centre of the boards’ upper surface until the Stop Purge button is
selected.
Purging should be monitored to ensure that the adhesive delivery is flowing
without being spurious or spluttering. Any signs of inconsistency are likely
to be due to air pockets in the delivery mechanism. Provided the assembly
has been set up correctly this should be almost negligible.
