⑴Manual
Soldering
Device
：
Soldering iron
①
380℃, Max.; 3 seconds, Max.
⑵Auto
Soldering（MHS121/MSH131/MHS221/MHS231 only）
Device
：
Jet wave type or dip type
① 275℃,
Max.; 6 seconds, Max.
●Pre-heating
should be done at temperatures ranging from 80℃
to 120℃ and within 120 seconds
⑶When
soldering two or more terminals to the common land,
use solder resist to solder them independently.
■Flux
Cleaning
⑴Solvent
: Fluorine or Alcohol type.
⑵Not
process sealed, if the PC board is to be cleaned, clean the
soldering surface of substrate with a brush so that the switch is
not exposed to the cleaning solution.
■Frequency
of switch use
If the switch is not likely to be operated frequently (e.g.
two or three operations a year) in the dry circuit area, a
sulfide film is likely to be formed on the contacts, resulting
in contact failure. If this is the case, gold-plated products
are recommended. Please contact your local Nidec Copal
Electronics sales representative.
