ii MAINTENANCE OF PRODUCTS CONFORMING TO RoHS DIRECTIVE
MAINTENANCE OF PRODUCTS CONFORMING TO RoHS DIRECTIVE
Work with care about followings for maintenance of products conforming to RoHS directive.
1. Identification
· For products conforming to RoHS directive, the letter “E” is appended at the end of the serial number on the
label. For models that the letter cannot be appended to the serial number, the letter “E” will be described in a
distinguishable position on the label. A description example on a main label is shown below.
· Print-circuit board of the products conforming to RoHS directive is manufactured by following methods.
[1] Blue resist ink is used for the print-circuit board. (The color of conventional print-circuit board is green.)
[2] Either one of the following marks is indicated by a serigraph or label.

2. Soldering
Since the melting point of lead-free solder used for the products conforming to RoHS directive is 20 to 45
degrees Celsius higher than that of conventional solder with lead (Sn-Pb eutectic solder), a high temperature
needs to be set to a soldering iron. Taking allowable temperature limit of the parts and stable work into
consideration, use a soldering iron with excellent thermal recovery characteristics.
· Recommended solder composition is “Sn/3.0Ag/0.5Cu” or equivalent.
· Separate the soldering iron exclusively for RoHS products and the soldering iron for conventional use.
· Set the temperature of the soldering bit to 350 to 370 degrees Celsius.
The temperature may need to be adjusted according to the size of the copper foil land on the print-circuit
board and the tip width of the soldering bit.
· Finish by a lead-free solder looks dull or whitish compared to conventional solder with lead.
3. Parts
Be sure to use parts conforming to RoHS directive.
