ELECTRICAL PARTS LIST·································· 25 Flexible Circuit Board Repairing - Keep the temperature of the soldering iron around 270°C during 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. Notes on chip component replacement - Never reuse a disconnected chip component. - Notice that the minus side of a tantalum capacitor may be dam- aged by heat. *Replacement of IC109 used in this set requires a special tool. -The voltage and waveform of CSP (chip size package) cannot be measured, because its lead layout is different from that of conven- tional IC. -Lead layouts Unleaded solder Boards requiring use of unleaded solder are printed with the lead- free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.) : LEAD FREE MARK Unleaded solder has the following characteristics. -Unleaded solder melts at a temperature about 40°C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350°C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! -Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. -Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder. surface Lead layout of conventional ICCSP (chip size package)
