4. solderingconditions
4.1 manual soldering :
temperature of solderingiron :300℃or less.
application time of soldering iron :within 3s.
4.2 dip soldering
printed wiring board: single-sided copper clad laminateboard with thickness of 1.6mm .
specific gravity: 0.82 or more.
flux shall be applied to the board using a bubble foaming typefluxer.
the board shall be soaked in the flux bubble only to the middleof its thickness.
flux shall not come into contact with the component sidesurface.
preheating:
surface temperature ofboard: 100℃or less.
preheating time: within 2 min.
soldering:
solder temperature: 260℃less.
immersion time: within 3 s.
4.3 apply the above soldering process for 1 or 2 times.
5. matters needingattention
5.1 high temperature high humidity or corrosive gases areprohibited in storage.
5.2 keep the principle of “first come, first use”.
5.3 the best way is to use the potentiometer as a four-terminalelement for adjusting voltage of voltage divider. for wiring, you’dbetter choose terminal “1”for grounding and r1 (the load resistanceof
the potentiometer) should be not smaller than tentimes as rt (see figure 2a).
except for special design re, thepotentiometer shouldn’t be used as a two-terminal rheostat. thecontact resistance between the resistor and the contact piece willhinder the passing of big electric current, at the sane time, thecurrent at the moving contact may be too big since only par of theeffective travel is in function and lead to local over loading thenfailure of the unit.(see figure 2b).
5.4 when the potentiometer is used as current regulator in dccircuit, dc current will pass the sliding arm thus resistance valuewill rise abnormally because of anodic oxidation. in this case, inthis case, it is recommended to connect the leading-out terminal ofthe resistor to the cathode and that of the sliding arm toanode.(see figure3c)
