How to Desolder?

Here’s how simple successful Thru-Hole De-soldering truly is: The Solution? Preheating! If a PCB Assembly can be made under 260°C in initial production, it can also be unmade and remade at similar temps!

 

Regardless of copper content, number of layers & heavy ground planes or component density, all you need is a PCB fixture, an AirBath preheating unit, a dependable (non-clogging) desoldering tool & a few other choice items and removing thru-hole IC's, resistors, diodes, capacitors, connectors is easy.

 
 

PCB Fixture.STEP 1: Secure your PCB into an ABC-1 Board Cradle and above the AirBath Preheater (not yet powered) as shown. Dip your brush into flux. (We recommend: No Clean Flux and Thru-Hole PCB Scrub Brushes).

 

How to Melt Solder for Removal.STEP 4b:  Heat the pin. Place the de-soldering tip’s orifice onto the joint’s stud. As solder melts, begin a rotating  motion with tip. When you sense the lead moving freely the solder is molten inside the hole.

 
 

How to Apply Flux?STEP 2a:  Apply flux to each of the targeted solder joint's lead and land/pad interface that corresponds to the Thru-Hole device on the opposite side of PCB.

 

How to Suck Up the Solder.STEP 4c: Activate Vacuum upon sensing the lead is loose in the hole. Now lower tip to the pad & begin vacuum. Continue rotation to prevent “sweating” inside plated holes. Don't use pressure.

 
 

How to Preheat PCBSTEP 2b:  Begin Preheating! Next,  begin the pre-heating process by flipping the rocker switch found on the AirBath to "Warm". (Typical preheating is done at 150°C).
 

  DeSoldering Techniques and Tips.

STEP 4d: After solder extraction, lift tip off the pad, but continue vacuum 3-4 extra seconds so solder travels to reservoir to prevent clogging or accidental solder spillage. Proceed to next joint. Turn power off.

 
 

What is DeSoldering?OPTIONAL 3a: Apply LowMelt®. Note: AirBath preheat power permits you to skip to Step 4, but if you have heavy ground planes, high copper content or really difficult PCB’s, consider the LowMelt® option.

 

How to Clean a PCB.STEP 5a:  Cool down & final cleaning.  Flip rocker switch of AirBath to “Cool” mode. This will cool down the PCB. Next, dip a brush into non-flammable flux remover.

 
 

Remove Chip Quick With LowMeltOPTIONAL 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® (Only use certified Zephyrtronics alloy).

 

Scrubbing the PCB Clean.STEP 5b: Clean PCB by brushing with non-flammable flux remover as PCB cools under the ZT-1 AirBath, (Clean as shown.  Inspect.  Turn off ZT-1 AirBath.  Flip PCB over and carefully extract chip or connector.

 
 

Desolder Process

STEP 4a: Now DeSolder! Use a temp controlled de-soldering station with temp set at less than 300°C, lower the de-soldering tip onto the solder joint stud, but do not lower tip completely to the pad yet.
