PCB Singulation Systems Die Packages
408-8649
Both stripping types rely on the spring (spider) plate in
the machine to provide sufficient force to trap the
printed circuit board before the perforators begin to
cut.
Due to the size and weight of the die packages, a cart
is recommended to transport the die package from its
storage location to the press (depaneling machine).
An access guard on the press is opened and the die
package is presented to the press using roller slides.
3. HANDLING
3.1. Uncrating
1. Remove the cover from the crate.
DANGER
The die package can weight up to 49.89 kg
[110 lbs]. In order to avoid personal injury, it is
recommended that at least two people (or an
adequate hoist) be used to lift the die package. In
addition, be sure to wear all personal protective
equipment (according to local practices).
2. Tilt the die package “up” in the front by lifting by
the handle and sliding it forward.
CAUTION
!
The die package is shipped with the upper
assembly and lower assembly together. Do not
lift the die package by the top plate. Always lift
using the handle and the other end of the lower
assembly to prevent accidental die separation.
3. Lift up the rear of the lower assembly and
remove the die package from the crate.
4. Place the die package on a work table.
5. Cut the band holding the upper assembly and
the lower assembly together.
6. Separate the die package by gripping the upper
assembly and lifting it off the lower assembly. Be
sure to keep the upper assembly square.
7. Place the upper assembly –– with the liner pins
facing down –– on the work table.
3.2. Inspection
1. With the lower assembly (die block) and the
upper assembly (punch holder) on a work table,
carefully inspect the die block for loose hardware,
debris, and broken parts.
2. Tilt the punch holder on its side (a maximum of
90 degrees) and inspect the punch holder for loose
hardware, debris, and broken parts.
NOTE
i
more Tilting the punch holder
than 90 degrees
may cause the hold downs/transfer pins
(pressure pins) to fall out. If this occurs, simply
replace the pins in the punch holder.
3. Immediately inform the shipper and Tyco
Electronics of any damage.
4. Remove the white grease (on the liner pins and
bushings) used for shipping. Apply a silicon
lubricant to the liner pins and bushings.
5. Reassemble the die package. It may now be
placed in short term storage for future use.
4. MAINTENANCE AND INSPECTION
4.1. Items Required for Maintenance
— Metal spacer blocks used to set the top
assembly (punch holder) on so that the liner pins
do not touch the work table
— Silicone lubricant or very light weight machine oil
NOTE
i
Silicone lubricant is preferable to oil, since debris
does not accumulate on silicone like it does oil
lubricant.
— White lithium grease (used instead of the
silicone or oil if the die package is to be stored for
any length of time)
— Spray cleaner and rags
4.2. Frequency of Maintenance and Inspection
Although the frequency of maintenance and
inspection is dependent on the ambient working
conditions in your facility and the skill of your
personnel, it is generally recommended that die
packages be cleaned, inspected for cut quality, and
lubricated every time they are removed from the
machine and placed in storage.
Die packages should be removed, cleaned,
inspected, and lubricated, after every 40 hours of
operation.
4.3. Maintenance Procedure
1. Separate the die package.
2. Place the upper assembly (punch holder) on the
work table.
3. Clean any dust, debris, and old lubricant from
the punch holder assembly.
4. Inspect the punches (perforators) for wear. If
repair is required refer to Section 5 for repair and
sharpening procedures.
5. Lubricate the liner pins.
6. Clean any dust, debris, and old lubricant from
the Lower assembly (die block).
7. Inspect the bushings for wear. If repair is
required, refer to Section 5.
