(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD
When repairing a lead-free solder PWB, use lead-free solder thread. Never use conventional lead solder thread, which may cause a breakdown or an accident. Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the exclusive-use soldering iron is recommendable.
(2) NOTE FOR SOLDERING WORK
Since the melting point of lead-freeCOPYRIGHT solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering XXXX BYSHARP CORPORATION capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when ALL RIGHTS RESERVED. completion of soldering is confirmed. Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently. If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron tip after completion of soldering work. No part of this publication may be reproduced, If the soldering iron tip is discolored black stored soldering work,system, orfile the tip within during in a retrieval clean and transmitted steel wool or a fine filer.
