B. Solder ing Process
Refer to Paragraph 2.5 for instructional material that is available for establishing soldering guidelines. The
switches can be soldered using wave soldering or equivalent soldering techniques. It is recommended
using SN60 or SN62 solder for these switches. The maximum solder profile temperature should be
245° +10°C [473° +10°F]. These switches are not recommended for reflow process.
C. Cleaning
After soldering, removal of fluxes, residues, and activators is necessary. Automatic in–line cleaning is
recommended for the sealed switch. Installation in a socket is recommended for the unsealed switch.
Consult with the supplier of the solder and flux for recommended cleaning solvents. Cleaners must be free
of dissolved flux and other contaminants. It is recommended cleaning with the pc board on its edge. If
using an aqueous cleaner, standard equipment such as a soak–tank or an automatic in–line machine
should be used. The following is a list of common cleaning solvents that will not affect the switches for the
time and temperature specified. See Figure 6.
NOTE
Vapor cleaning (with the pc board on edge) is preferred over submersion in a liquid cleaner. Unsealed switches should
not be submerged due to contaminants in the cleaning bath.
CAUTION
Do NOT ultrasonically clean switches sealed with tape or masking material.

DANGER
Consideration must be given to toxicity and other safety requirements recommended by the solvent manufacturer.
Refer to the manufacturer's Material Safety Data Sheet (MSDS) for characteristics and handling of cleaners.
Trichloroethylene and Methylene Chloride is not recommended because of harmful occupational and environmental
effects. Both are carcinogenic (cancer-causing).
