Lead-free soldering machine of Daitoku Tech is controls the consumption
of
the electric power,
and the latest machine also in the environment designed easily valuing
the easiness of maintenance.
Features of Lead-free soldering
■The erosion is controlled with the solder pot of the cast iron and ceramic
coating,
and solder dross is suppressed to the minimum.
■7inch TFT touch panel is adopted.
①The soldering condition can be registered by 100 files
②The height of the solder wave can be adjusted while confirming the
operation panel.
③It displays it by as much as 100 production data, if the printer is
connected,
the print out is also possible.
④PC communication
⑤An abnormal detailed content and an abnormal record are displayed.
■The top and bottom of the solder pot and drawing out adopt
the warm mechanism method, and aim at the improvement of maintenance.
■The pre-heater facilitates the maintenance work by the front drawing
out type.
■The solder wave nozzle can adjust the flow velocity of solder, the dipping
time, and
the peel back point. Therefore, it is possible to correspond
to diverse-types-and-small-quantity production.
■The conveyer finger is a steady design that can correspond to many kinds
of PWBs, and
the adhesion of solder is reduced.
