AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY 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 itr 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 Notes on chip component replacement Never reuse a disconnected chip component Notice that the minus side of a tantalum capacitor may be damaged by heat SA WMS25 SECTION 1 DISASSEMBLY e The equipment can be removed using the following procedure DSP BOARD PS BOARD DIGITAL AMP BOARD Note Follow the disassembly procedure in the numerical order given
