Faktisk skal den indvendige diameter på nålen på limdispenseren være 1/2 af diameteren af udleveringspunktet. Den automatiske limmaskine har højt teknisk indhold, men omkostningerne er høje!
Limens viskositet og viskositet påvirker direktelim quality of the lim
dispenser.
Manuel distribution, den automatiske skruemaskine vedtager princippet om manuel distributør til distribution af elektroniske produkter, processen er enkel, omkostningerne er lave, og ulempen er spild af arbejdskraft!
The principle of
the automatic dispenser is to push out the lim with air pressure within a set
time.
Just choose the appropriate syringe according to the air pressure, time,
and you can easily change the volume of each injection. This can ensure the
quality of lim dots and improve production efficiency. When the viscosity is
high, the lim spots can be reduced, and even wire drawing can be performed. If
the viscosity is small, the lim spots can be increased and the pads can leak.
The time of each infusion is controlled by the instrument to ensure that the
amount of each infusion is the same. When distributing, you should choose the
dispensing needle according to the size of the gasket on the PCB. Choose the
same needle but different phase difference
gaskets should choose different dispensing needles.
