The roller bearings may have to be removed if
they will prevent setting the bottom of the die
block flush with the face of the grinding table.
NOTE
i
If rollers are removed, be sure a washer is placed
between the roller and the die block.

A. Perforators
1. Using an angle diamond dressor, dress an angle
into the grinding wheel. See Figure 5.
2. Place the punch (perforator) into perf bar. See
Figure 6. Perf bars are available from Tyco
Electronics (contact PCB Singulation Systems
Customer Service at 1–888–782–3349). Perf bars
can hold up to ten perforators at a time.
3. Place the perf bar and perforators on the
grinding table as shown in Figure 7.

NOTE
i
Be sure there is sufficient clearance between the
grinding wheel and the highest part of the
perforators before placing them on the grinding
table.
4. Before sharpening, be sure to measure from the
face of the perforators to the face of the punch
using a depth micrometer. Compare the
measurements to those listed in the Die Repair
and Sharpening Log. If the measurements are not
the same, refer to the die package top assembly
drawing for starting measurements.
5. Sharpen by removing enough stock from the
perforator face to provide a clean, sharp cutting
surface (normally 0.127 mm to 0.254 mm [.005 in.
to .010 in.]).

CAUTION

DO NOT remove more than 0.025 mm [.001 in.]
at a time or the perforator punches may break.
