HOW TO DESOLDER THROUGH HOLE COMPONENTS, CONNECTORS & CHIPS?
|
|
|
Through Hole De-Soldering Finally & Truly Made Really Easy!
Thru-Hole De-Soldering Without Lifting Pads & Traces!
|
|
|

|
What's
the best way to desolder PC Boards? With preheat! Remember,
David Jacks, president of Zephyrtronics pointed out way back
in 1994: "if a PCB Assembly can be made under 300°C in
initial production, then it can also be unmade and remade at
similar temps! |
|
|
So
regardless of copper content, number of layers & heavy
ground planes? Yes. But you need a
PCB fixture, an
AirBath
preheater, a non-clogging
de-soldering
tool
and you're there. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
STEP 1:
Secure your PCB
within the
ABC-1 Board Cradle above the
ZT-1 AirBath (not powered) as shown.
Generously dip your brush into flux. (Recommended: No Clean Flux
NCF-0014
&
THB-0144
Thru-Hole Brush) |
|
STEP 4b:
Heat the
pin. Position the DeSoldering Tip’s orifice over the joint’s lead/stud.
As solder melts, start a rotating motion with tip
until you “sense” the pin moving freely. |
|
|
|
|
|
|
|
|
|
|
|
STEP 2a:
Apply
your flux
to targeted solder joint's individual leads and land
interface that corresponds to the Thru-Hole device,
connector or chip on the opposite side of your PCB assembly
you wish to desolder and remove. |
|
STEP 4c:
Activate Vacuum!
Sensing the pin
loose in the hole and solder is molten, lower tip to pad
& begin vacuum. Rotating on pin prevents “sweating”
of “plated thru-holes”. Do not exert pressure
on pads. |
|
|
|
|
|
|
|
|
|
|
|
|
STEP 2b:
Begin Preheating! Next, begin the pre-heating process by flipping the rocker switch found on the
AirBath to "Warm".
(Typically preheat is at 150°C). |
|
STEP 4d:
After
extracting solder from hole, lift tip up off the
pad and continue vacuum 3-4 extra seconds. Proceed to next joint. Turn off power when done. |
|
|
|
|
|
|
|
|
|
|
|
|
|
STEP 3a:
Apply
LowMelt®.
Note: The
preheat advantage permits skipping to Step 4. Still with
extremely heavy ground planes, high copper content PCB’s,
a "boost" option is to use a strand of certified
LowMelt®
DeSolder
Wire as shown. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
STEP 3b:
Melt
LowMelt®. directly onto existing joints as needed. Co-metalization has begun! Because no two PCB’s are alike, some joints will require more
LowMelt® (Note: Only use certified Zephyrtronics alloy). |
|
|
|
|
|
|
|
|
|
|
|
|
 |
|
STEP
4a:
Ready for
DeSoldering! Using a MIL-Spec, temp controlled
thru-hole de-soldering tool
set at no more than 300°C, take
the Desoldering Pistol and lower the Desoldering Tip onto
the solder joint stud. Be careful and do not lower tip to
the pad at this point. |
