DESOLDERING ELECTRICALLY SENSITIVE COMPONENTS
Pace Power Sources with “Zero Power Switching” and all PED-A-VAC’S can be used with SX-20, SX-25 and
SX-30 Desoldering Handpieces for safe removal of components. Power Sources without “Zero Power
Switching’ capability can safely remove sensitive components when used with the SX-20V, SX-25V and SX-30V
Desoldering Handpieces. However, it is necessary to actuate the vacuum pump before the desoldering tip con-
tacts the component lead, and continue the pump operation until the desoldering action is complete. Vacuum
actuation is by finger tip control as described in this manual.
PROCEDURE FOR REMOVING GLASS CHAMBER
The Dual Path Solder Extractor is designed with a solder well which sits between the transfer tube and front
seal tube (see illustration below). This feature contributes to the efficient operation of the Dual Path. Under nor-
mal operation, the well is maintained at a temperature above that of solder melt and therefore any solder falling
into the well will remain molten. The following procedure should be followed before removing the Glass Chamber.
1. While the extractor is hot, hold the extractor vertical, with the desoldering tip pointing straight-up.
2. Gently tap the side of the extractor handle to loosen any molten solder that may be in the well so that gravi-
ty will flow the solder into the Glass Chamber.
3. While still holding the extractor vertically, apply two or three blasts of vacuum as to suck any loose solder
into the Glass Chamber.
You are now ready to remove the Glass Chamber from the Dual Path Solder Extractor for cleaning.

THEORY OF OPERATIONS,
DUAL PATH SOLDER EXTRACTOR
The Solder Extractor functions as a vacuum cleaning device to remove solder. Heat sup-
plied to the hollow tip (FIGURE 2) melts the solder, activating the vacuum flow which ex-
tracts the liquid solder from the joint and transfers it quickly and safely to the solder collec-
tion chamber within the handle.
== =
FIGURE 2. CUT-AWAY VIEW OF DUAL PATH SOLDER EXTRACTOR MODEL SX-25
The “V” Model Solder Extractors (FIGURE 3) have the same features as above Models, and an addi-
tional air switch/tube assembly to the handle for permitting instantaneous finger-tip-actuated
vacuum control. This vacuum control gives users “Spike Free” desoldering capabilities for CMOS
and similar static sensitive components (when used with power sources not equipped with elec-
tronic “Spike Free” Power™ output).

THEORY OF OPERATION
All Dual Solder Extractor models allow guick hand-removal of the solder collection
chamber (FIGURE 4) for maintenance. The collection chamber is removed by a guick-twist
without touching the hot chamber or of disturbing or disconnecting any heated elements or
electrical connections. Ingested volatized flux and coating are prevented from entering the
pump or vacuum source by the primary filter at the inside rear of the glass chamber. This
filter is easily visible through two inspection ports in the handpiece and should be replaced
when discolored.

TIP SELECTION GUIDE
One of the most important aspects for successful solder extraction is the selection of the proper
size of Tip for the job. Keep several points in mind while selecting the Tips:
OPERATION ~
| Clearance
STEP 1. The Inside Diameter (1.D.) of the Tip must be large
enough to fit loosely over lead to provide clearance for air
and molten solder flow.
STEP 2. The Outside Diameter (0.D.) of the Tip must be
smaller than the pad diameter to permit contact with the
copper pad while preventing contact with the base material.
STEP 3. Match the Tip to the work. Small I.D. Tips for small
leads, larger Tips for heavier leads.
STEP 4. For desoldering terminals and solder splash
removal, use largest I.D. Tip available.

INITIAL START-UP ALL MODELS
To operate the Solder Extractor (all models),
a. place Solder Extractor in stand
b. set Temperature Control to 10
c. allow three (3) minutes warm-up time
d. reduce temperature. A temperature setting of 7% to 8% is normal for most
desoldering tasks
e. use the Extractor
V-MODEL OPERATION
To operate the “V” Model SX-20V, SX-25V and SX-30V Handpiece controlled vacuum
Extractors:
a. Hold the handpiece as you would hold a pencil (FIGURE 7). Hold your index
finger bent, with the tip of the finger resting firmly on the flat portion of the
Vacuum Control Bar, and just behind the orifice.
b. On the Power Source, turn Pump switch to the “ON” position (Refer to Opera-
tion and Maintenance Instructions for your Power Source).
c. To actuate the vacuum, slide your finger tip firmly forward to completely seal the
orifice. As long as the orifice is closed, the vacuum is actuated through the Sodr-X-
Tractor tip. Keep moving the component lead with the Solder Extractor tip during
full vacuum operation. Continue stirring lead to cool down the joint.
d. After extracting the solder, remove the extractor tip from the joint, then slide
your finger tip back off the orifice to terminate the vacuum. (If operation is
completed, turn off pump. See Operation and Maintenance instruction for
your Power Source).

(OPERATION
VACUUM EXTRACTION
When performing a desoldering operation, the following steps should be followed for best results.
STEP 1. Position the Tip over the lead making contact with
solder. As the solder melts, allow the Tip to gently rest on
a film of solder between solder and Tip.
STEP 2. Move Tip with a stirring motion, dwelling until lead
moves freely within the board hole. Free movement of the
lead indicates complete solder melt.
STEP 3. Apply vacuum and continue stirring action dur-
ing vacuum application. To remove solder, maintain light
contact. (NOTE: Pressure can damage or lift the pad).
STEP 4. Continue stirring action and vacuum flow to cool
joint area.
STEP 5. Continue vacuum flow one or two additional
seconds after removing Tip from the board to assure com-
plete transfer of the solder to Chamber.
STEP 6. Check your work. If any solder remains in a plated-
thru hole (PTH) after extraction, resolder and extract again

STEP 11. For solder extraction on terminals, increase heat
setting. Place Tip in contact with wire and solder. Watch
for complete melt. Wiggle wire and apply vacuum to ex-
tract solder. Keep wire moving during cool down.
STEP 12. Solder extraction on multilayer boards may re-
quire application of a second heat source at the joint on
the convenient side. Use a PACE Conductive Heating
System or hot soldering iron tip for auxiliary heat.

OPERATION
PRESSURE MODE
(USE OF AIR PRESSURE)
The following procedures apply when the extractor is used with Power Sources equipped with a
controlled air pressure outlet.
Circumstances may occur when the Vacuum Mode of operation will not completely remove a
solder joint. This is most often the case when a “Blind-Sided Solder Joint” is found. The “Blind-
Sided Solder Joint” is so named because of its inaccessibility, usually on the component side of
the board. This is common when a terminals flanged end (on opposite side of board) blocks air
flow. In this case the vacuum method is not applicable since no cooling air can be pulled through
the hole thus causing a sweat joint. So in this case (see Step 7 on page 11; and steps below).
The “Pressure Mode” is now required to break up this Blind-Sided Solder Joint. The “Pressure Mode”
uses the following steps:
a. Connect the air line to the Pressure Flow control valve and adjust Pressure control
to “maximum”.
b. Place the tip of the Extractor into the “Solder Dump” between the two “Hot
Cubbies”, and use a burst of pressure to clear any molten solder which might be in
the heater tube.
c. Heat must be transmitted through the lead to melt the Blind-Sided Solder Joint.
Place the heated tip over and in contact with the lead.
WARNING—ALLOW THE TIP TO COME INTO LIGHT CONTACT WITH THE PAD
AREA.
d. When the Blind-Sided Solder Joint is heated sufficiently, actuate the airflow to pro-
vide continuous burst of pressure. Stir the lead to prevent reformation of sweat
joints caused by the continuing flow of air.
If conformal coating is blocking air flow, the coating must be removed before the vacuum
desoldering operation. Try hot air jet to decure coatings; or thermo-plating tool to remove coatings
(See hot air jet page 13.)

OPERATIONS
HOT AIR JET MODE
The hot air mode of operation is used for several different applications:
+ SURFACE SOLDERED JOINTS
Surface solder joints are removed with the “Hot Air Jet Mode” of operation. The follow-
ing steps should be taken for the succesful removal of surface mounted components.
a. With the air line connected to the Pressure Flow Control Valve on the Power
Source, set Pressure valve and power to “MAX” and blow out excess molten
solder.
b. Reduce the Pressure valve setting to “MIN” and use .036 1.D. Tip.
c. A carefully-directed Hot Air Jet will melt the solder joint when the tip is held
approximately Ys” from the surface. When you see the solder melt, lift the
lead with a soldering aid or tweezer. Do not lift before melting is observed, or
you might lift the pads from the substrate.
d. Repeat this process for each individual lead until all leads are removed and
the component is free.
GENERAL NOTE
If surface joints are heavily mounded with solder, it may be
desirable to use the Vacuum Mode to remove excess solder
prior to using Hot Air Jet Method.
¢ HEAT SHRINKABLE TUBING
To use Hot Air Jet Mode of Operation for shrinking tubing, apply the properly adjusted
jet slowly along the entire length of the tubing. Do not play the hot air at one point, but
evenly distribute heat to shrink tubing. Be sure all tubing has shrunk completely before
allowing it to cool.
¢ CONFORMAL COATING REMOVAL (Epoxy and Polyurethane)
Apply Hot Air Jet to the conformal coating to be removed. Remove the softened coating
with an orange stick so you won't damage the board.
* REMOVAL OF BONDED COMPONENTS
Apply Hot Air Jet to the component body and surrounding area to soften the bonding
material. Then twist the component to be removed with pliers or tweezers. Heating may
be required for 2 or 3 minutes, depending upon the size of the component and the
thickness of the coating.
13

„MAINTENANCE
TIP CARE
The Extractor Tips should be cared for in the same manner as soldering iron tips. The
following suggestions will prevent damage to the handpiece assembly:
* Remove excess solder, burned flux, and conformal coatings by lightly wiping the tip on
a non-contaminating material.
+ The Solder Extractor Tip is expendable; washout (thinning) of the inside bore occurs
during normal use. The Tip must be replaced before it becomes so thin that it breaks off
in the heater assembly.
* Charred coating of flux can cause blockage in the tip bore. Clear the residue from inside
the tip with a length of small-diameter stiff wire.
BROKEN TIP REMOVAL
If the tip breaks off in the Heater assembly, remove power cord from power source. Use a
steel rod, slightly less than 1/8 inch in diameter, to ram the broken tip out of the Heater tube
while the Extractor is still hot. With set screw removed, insert ram from handle end while the
front face of the heater is supported and drive the broken tip out. (FIGURE 8)
FIGURE 8. BROKEN TIP REMOVAL

MAINTENANCE.
TIP REPLACEMENT PROCEDURE
a. While the unit is idling hot, loosen set screw to free the tip.
. Remove the Tip from the Heater.
. Clean Heater with small wire brush to remove oxide buildup.
. Place new Tip in Heater with hangout of 1% to %.
. Tighten set screw 1/8 turn past the point of contact to secure Tip in place. 200
NOTE
Although set screws are permanently lubricated, it is essential
that the screw be loosened and the tip be removed at least
once every eight operating hours.
CLEANING SOLDER COLLECTION CHAMBER
Solder and flux buildup in Chamber depends upon use. Clean Chamber and “S” Baffle as
often as necessary with a large bristle brush. Apply mineral oil to the brush and lightly coat
inside of Chamber and “S” Baffle.
REPLACING PRIMARY VISIBLE FILTER
The white, primary Sodr-X-Tractor Filter located within the rear of the Glass Chamber
(FIGURE 9) should be changed whenever heavy deposits of contaminants are noticeable. It is
very important that this filter be kept clean; this assures optimum air flow and minimum flow
restriction, and keeps contaminants from reaching the vacuum source.
