Step
1
Step 2A
Always Preheat First. Place your PCB into your fixture above the
ZT-1 AIRBATH
as shown at the left. Begin the preheat process by flipping the rocker switch
the "Warm." mode (Recommended setting: 150°C)
Dip Swab Into Flux.
As PCB pre-heats, insert a small anti-static foam swab into flux as shown. (Recommended:
A thin anti-static foam swab and tack flux
no-clean lean flux).
Step 2B
Step 3A
Apply Flux. Make application of flux to each lead/land interface of the targeted SMD to be removed.
Swabs
are most helpful as shown at left.
Select LOWMELT®. Take a single strand of certified
LOWMELT® DeSolder wire from its tube
(shown in right photo). Note: Only use certified Zephyrtronics alloy.)
Step 3B
Step 3C
Apply LOWMELT®.Using economy and in a random manner, melt
LowMelt® into existing joints of the SMD only as each lead requires. Co-metalization begins.
Because no two PCB's are the same and some joints will always have more solder than others, some leads will need more
LowMelt®. Typically (not always), an SMD's four corners need a bit more.
Step 4
Lift and Remove SMD. With a soft suction lifting device like the
ZT-3-MIL AirPick, lift
the chip from the PCB. (Use of the ESD safe ZT-3 guarantees no lifting pads.)
Step
5A
Easy Clean Up.Dip Swab Into Flux. Maintaining pre-heating at 150°C, insert anti-static foam swab into flux as shown. (Recommended: the
anti-static
swabs and
a
no clean tack flux).
Step
5B
Remove Excess Solder. Using fluxed swab, gently push residual solder into a single
sphere and remove with solder sucker or push up onto a card.
Step
5C
Repeat Step 5b. Good rule of thumb: Repeat cleaning with a
fresh swab pre-dipped in your flux. This second flux swabbing
polishes your pads in prep for new SMD placement.
Step
6A
Step
6B
Cool Down & Final Cleaning. Flip rocker switch of
ZT-1 AirBath
to "Cool" mode to cool down PCB. Insert foam swab into flux
remover. We recommend using a
non-flammable
flux remover.)
Swab PCB with Flux Remover. As PCB cools under
ZT-1 AirBath, swab area where SMD was removed with Flux Remover as shown.

Inspect. Inspect your substrate and pads. Turn off
ZT-1 AirBath. Note: the entire removal process was with non-contact warm air below 150°C.
How to Solder SMD
Chips? After chip removal,
it's easy to place and solder a new one back to the
pads using solder paste right at your bench.
