3.4. Soldering

Guidelines

The pins can be soldered using wave soldering techniques. The temperatures and exposure time must be

within the ranges specified in Figure 3.

Flux Selection

Pins must be fluxed prior to soldering with a mildly-active, rosin base flux. Selection of the flux will depend

on the type of pc board and other components mounted on the board. Additionally, the flux must be

compatible with the wave solder line, manufacturing, health, and safety requirements. Fluxes that are

compatible with these pins are provided in Figure 4.

Cleaning

After soldering, removal of fluxes, residues, and activators is necessary. Consult with the supplier of the

solder and flux for recommended cleaning solvents. Common cleaning solvents with times and

temperatures that will not affect these pins are specified in Figure 5.

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).
