Caution 3
Due to the higher melting point of lead free solder the soldering iron tip temperature needs to be set to 370 degrees centigrade this requires soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics 3
Example 1 3
Example 2 3
For more information on the use of lead free solder please refer to http www sony training com 3
It is strongly recommended to use lead free solder material in order to guarantee optimal quality of new solder joints lead free solder is available under the following part numbers 3
Lead free soldered boards 3
Table 1 3
The circuit boards listed below table 1 used in these models may have been processed using lead free solder the boards are identified by the lf logo located close to the board designation e g f1 h1 etc see examples the servicing of these boards requires special precautions to be taken as outlined below 3
