Unleaded solder has the following characteristics. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time.
Caution: The printed pattern copper foil may peel away if the. Unleaded solder is more viscous sticky, less prone to fl ow than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.
It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder. Laser component in this product is capable of emitting radiation exceed- ing the limit for Class 1. This marking is located on the rear or bottom exterior. CAUTION Use of controls or adjustments or performance of procedures other than those specifi ed herein may result in hazardous radiation exposure.

Unleaded solder is more viscous sticky, less prone to fl ow than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.
Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be dam- aged by heat. 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. Check leakage as described below. Leakage current can be measured by any one of three methods.
A commercial leakage tester, such as the Simpson or RCA. A battery-operated AC milliammeter. The Data Precision Measuring the voltage drop across a resistor by means of a.
VOM or battery-operated AC voltmeter. Nearly all battery operated digital multimeters that have a 2 V AC range are suitable. See Fig. Using an AC voltmeter to check AC leakage. Laser component in this product is capable of emitting radiation exceed- ing the limit for Class 1.
