Features
A sequential application method which
allows control of the amount of adhesive
according to the type and shape of
components.
A system in which adhesive is applied at
a stroke through a screen. This method
can save time required for application,
though it requires set-up change when
PCBs are changed. In this method, no
coating is allowed after components are
mounted.
The application of adhesive is completed
at once with transfer pins. The amount of
adhesive cannot be controlled in this
method.
