(3) Measurement As shown in Figure 9, place
on a flat surface for more than 12 hours and
calculate the number of points off the flat
surface less than 2 mm high.
8.8.4 Camber
(1) Equipment Use a scale that measures at
least 1 mm increments.
(2) Material Cut a section of more than 30
cm, but less than 100 cm in length of TCP
polyimide adhesive tape as received.
(3) Measurement As shown in Figure 10,
connect corners of the tape in a straight line,
and measure the deviation from the line to
the edge of the tape at the center.
8.8.5 Twist
(1) Equipment Use a protractor that measures
at least 1 degree increments.
(2) Material Cut a section of 1 meter in
length of TCP polyimide adhesive tape as
received.
(3) Measurement Hang the tape vertically
and measure the angle of twist of the bottom
edge as opposed to the top edge.
8.8.6 Defects
(1) Equipment Use a 10 power magnifying
glass or naked eye.
(2) Material Use TCP polyimide adhesive
tape as received. The length should be
determined between the user and supplier.
(3) Measurement Perform a check on defects
against a limit sample determined by the
user and supplier. Unless otherwise
specified, the " Admixture Measurement
Table" from the JIS P-8101 standard
(Finance Ministry Printing Press) is
recommended.
