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.
