LowMelt® DeSolder Wire     Removes Chip Quick & Easy       SMD Removal     PCB Rework & Repair    SMT DeSoldering
Low Temperature SMD & Thru-Hole Removal. Available Also in a Lead-Free and RoHS Compliant Formulation!

 Step 1

Preheating PCB

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)

 Step 2A
Fluxing PCB

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 Flux).

 Step 2B

Appy Flux

Apply Flux. Make application of flux to each lead/land interface of the targeted SMD to be removed. (Note: For graphic contrast, a white foam swab is shown at left).

 Step 3A

Select LOWMELT®. Take a  strand of  LOWMELT® DeSolder wire from  tube as shown in the right photo. (Note: Only use certified Zephyrtronics alloy.)

 Step 3B

LowMelt to Remove Chip Quick

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.

 Step 3C

LowMelt DeSolder Wire

Because 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
SMD Removal

Lift and Remove SMD. Using a soft suction lifting device such as the ZT-3-MIL AIRPICK, lift SMD up and off of the PCB. (Note: Use of the ESD safe ZT-3 guarantees no lifting of 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 Swab and tack NoClean Flux).

 Step 5B
PCB Clean Up, LowMelt

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
Polishing Pads

Repeat Step 5b. A good rule of thumb: repeat cleaning with a new, large foam swab dipped again in flux. This second flux swabbing polishes pads in prep for new SMD placement.

 Step 6A
Non-Flammable, Flux Remover

Cool Down & Final Cleaning. Flip rocker switch of ZT-1 AirBath to "Cool" mode to cool down PCB. Insert large anti-static foam swab into flux remover. (We recommend A Non-Flammable Flux Remover.)

 Step 6B
PCB Final Inspection

Swab PCB with Flux Remover. As PCB cools under ZT-1 AirBath, swab area where SMD was removed with Flux Remover as shown.

 Step 7

P C Board Inspection

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.


Now that you have successfully removed your SMT component, it's just as easy to place and solder a new one back onto the pads. For SMD placement and soldering, please be sure to see our full color, step-by-step Process Guide at "SMD Soldering As It Should Be" or check out the short, but helpful video at the right.
