Since the early 80's ESP has been involved with making welding
equipment for the electronics industry. Over the years, we have been involved
with every aspect of this field and have acquired a great expertise
Hermetic Package Welders for the Electronics Industries. Sealing
such package types as:
TO, DIP, Flatpack, Seam, Optical, Laser and other similar package types.
Below are descriptions of each welder type
and what it's used for.
Specialty:
There are those applications which do not fit into other categories. These are
the specials or one-of-a-kinds. Often for some specific purpose and often for
only one company. These welders are most often NOT for the Electronics
Industries. They could be for ANYTHING that needs to be welded.
Single:
These are the 'Standard' one-part-at-a-time welders. Put the part in, weld,
then remove the part. There are variations on this theme. Often parts are
automatically ejected after welding. We have light curtains which automatically
initiate the weld sequence after the operator automatically loads the part and
removes their hands. There are options which greatly increase production rates.
Other options allow Vacuum or some gas to be placed inside the part before
welding. Typical components would be Crystals, Optical Devices. TO or DIP type
packages or Pressure Sensors, or just about anything that needs to be sealed
inside a Hermetic Package. Typical configuration would be with Electrodes coming
together in a vertical method. Seam:
Also known as: parallel gap roller welding. This method uses two conductive
rollers to pass current through the metal 'lid' to 'melt' (braze) the lid to the
can. Typically used for Flatpack type packages. This type welder usually appeals
to the Hybrid Industries. Rotary:
A variation on the Single Weld Head. The main difference is that now there are
parallel operations going on. There are usually 4 or more positions. One for
welding while there is another for unloading and another for loading. This
usually increases production rates as there are multiple actions going on at the
same time. There is really minimal speed increases using this method and often
not really worth it considering the additional cost and complexity as compared
to the Single with some options such as automatic ejection and light curtains. Inline:
This is the most exciting recent development. This welds a series of packages
at a high speed in one single long electrode bar. Recent production developments
allow processing parts at a higher rate using a 'batch' processing 'common
carrier' strip. Packages are loaded up to 50 at once, welded and then unloaded
together. This greatly increases continuous
production rates into the thousands per hour! Accessories:
Often there are additional processing requirements. Environmental chambers, gas
mixers, gas dryers, ovens, pass thru, moisture analyzers
and other devices to watch, control, assist, and whatever else needs to be done
for the production needs of the specific customer. While we have some 'standard'
accessories, there is no limit as to what is possible. Just ask! |
