3-4-2. Removing the Part
(1) Using special desoldering iron:
Select soldering tip according to part size.
@) Bring the tip into contact with the soldered points.
@) When the solder melts, remove the part.
@Remove the old solder with desoldering wire.
(1) Using two soldering irons:
CD Use small flat-blade tips.
@) Heat both ends of the part simultaneously.
@) When the solder melts, grasp and remove the part
with the soldering iron tips.
@ Remove the old solder with desoldering wire.
3-4-3. Installing the Part
(1) Clean the area where the new part is to be
mounted.
(2) Apply flux
(3) In part correctly into position, prevent it from
shifting.
(4) Use sharp soldering iron tip. Bring close to the
part contact without actually touching it. Melt thin
solder between the tip and part so that if flows
into the part contact.
(5) Check work quality with a magnifier.
