LOWMELT® DE-SOLDER PROCESS
Low Temperature SMD and Thru-Hole Removal! It's Easy!
Now Available Also in a Lead-Free and RoHS Compliant Formulation! We Pioneered it!
 
 Step 1  Step 2A

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)

 

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 lean flux).

 
 Step 2B  Step 3A

Appy Flux

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

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.

 

LowMelt DeSolder Wire

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

SMD Removal

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
PRO 8
 

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.

PCB Clean Up, LowMelt
 
Step 5C
  Polishing Pads

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
Non-Flammable, Flux Remover

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.)

  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

 Video Demonstration: SMD Removal & LowMelt®

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.

   

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.

 See our color step-by-step process guide "SMD High Quality Soldering As It Should Be" or, for a real treat, watch the short video at the right. And prepare yourself to be amazed.
