5. Service points

Lead-free solder

This product uses lead-free solder (unleaded) to help protect the environment. Please read these instructions
before attempting any soldering work.

1) Lead-free solder indicator

Printed circuit boards using lead-free solder are engraved with an

2) Properties of lead-free solder

The melting point of lead-free solder is 40-50 ℃ higher than leaded solder.

3) Servicing solder

Solder with an alloy composition of Sn-3.0Ag-0.5Cu or Sn-0.7Cu is recommended. Although servicing with
leaded solder is possible, there are a few precautions that have to be taken. (Not taking these precautions
may cause the solder to not harden properly, and lead to consequent malfunctions.)

label.

Precautions when using leaded solder

● Remove all lead-free solder from soldered joints when replacing components.

● If leaded solder should be added to existing lead free joints, mix in the leaded solder thoroughly after the

lead-free solder has been completely melted (do not apply the soldering iron without solder).

4) Servicing soldering iron

A soldering iron with a temperature setting capability (temperature control function) is recommended.
The melting point of lead-free solder is higher than leaded solder. Use a soldering iron that maintains a high
stable temperature (large heat capacity), and that allows temperature adjustment according to the part being
serviced, to avoid poor servicing performance.

Recommended soldering iron:

● Soldering iron with temperature control function (temperature range: 320-450℃)
