Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.

than ordinary solder so use caution not to let solder bridges oc-
cur such as on IC pins, etc.

ISO9660 Format
The most common international standard for the
logical format of files and folders on a CD-ROM.
There are several specification levels. In Level 1, file
names must be in the 8.3 format (no more than eight
characters in the name, no more than three characters
in the extension “.MP3” or “.JPG”) and in capital
letters. Folder names can be no longer than eight
characters. There can be no more than eight nested
folder levels. Level 2 specifications allow file names
and folder names up to 31 characters long. Each
folder can have up to 8 trees.
For Joliet in the expansion format (file and folder
names can have up to 64 characters) make sure of the
contents of the writing software, etc.

Multi Session
This is a recording method that enables adding of
data using the Track-At-Once method. Conventional
CDs begin at a CD control area called the Lead-in
and end at an area called Lead-out. A Multi Session
CD is a CD having multiple sessions, with each
segment from Lead-in to Lead-out regarded as a
single session.
CD-Extra: This format records audio (audio CD
data) on the tracks in session 1 and data on the tracks
in session 2.
