LOWMELT® DESOLDER WIRETruly Low Temp SMD & Thru-Hole Removal & BGA Pad Re-Dressing Solder for Your PCB's!
You Choose! Now Also Available in a Lead-Free and RoHS Compliant Formulation! In-Stock!
ThruHole Removal Below 150°C (302°F)
SMD's At Temps Below 150°C: Yes,our
and Thru-Hole chips at temperatures
hundreds of degrees below other de-soldering
methods. Below 150°C! And
in both RoHS compliant (lead-free)
and in classic leaded alloys.
Nozzles! And LowMelt®DeSolder Wire removes most chips without
scorching, clumsy and pricey nozzles
for every SMD chip! That's right...absolutely
no nozzles! LowMelt®
de-solders through the decades-proven Co-Metalization
with only a pre-heater below the PCB!
If you don't have a preheater, use your desoldering tool
or a simple soldering iron. Rework benches should have LowMelt®
at the technician's fingertips when needed. It is an
essential for any electronic assembly or rework bench.
And a little goes a really long way!
Just a dab at the pin/lead interface. Remove large SMD's
with a mere few inches.

Re-Dressing BGA Pads:
LowMelt®is ideal for re-dressing
BGA pads after chip removal eliminating the
problematic braided wick and hot
contact soldering irons that scratch and
hurt a BGA. Remember, the delicate pads on
a BGA chip are far weaker than even the pads
on a PCB which is what makes LowMelt®
such a valuable tool to have on hand at any

Historical Perspective of LowMelt®
DeSolder: You may be surprised to
learn that a more primitive use of low
temperature solder alloys for component removal had
actually been around a very long time.
This brilliant concept was originally
pioneered by the late Joseph Funari in
A decade later in the
1970's, William C. Ward of IBM,
explained and published Funari's
concepts in IBM's Technical Disclosure
there was a very clever Russian
patent also issued many decades ago combining both a
low melting point solder with a soldering iron to
remove electronic chips. How about that?
The same week,
Zephyrtronics was awarded
"Best New Product" of the year
winning the prestigious Vision Award,
as the company's then jaw-dropping and
innovative process of co-metalization
and non-contact, "touch-free" rework
dazzled engineers and technicians. And how quickly the word

Technical Disclosure Bulletin: Low
Temp Alloys for Chip Removal
Works With Soldering Irons, But Better
With Non-Contact Preheat:
Customers ask us: why not
recommend using ordinary soldering
irons to mix the LowMelt®
directly into the chip's existing solder
joints to remove chips? Of course, this
technique -- as mentioned above -- has
been around since the 1960's, so
works this way. But...
Dr. Charles Hutchins, a
founder of Surface Mount Technology
Association (SMTA), wrote most PCB damage during rework and repair
results from either high temperatures, excessive
hand pressure or a combination of both.
Of course, a soldering iron introduces
high temps, hand pressure and contact
into the equation.
So, Yes, It "Works", but we say
there's just a far better, lower
temperature and 100% non-contact
method. Since the 1990's,
Zephyrtronics, pioneer in this
technology synergy, has recommended using a
Pre-heater beneath the PCB in
LowMelt®DeSolder Wire as shown the video
above. This superior method is what NASA
called "touch-free," and maximizes the
benefit of low temperature rework.
Certainly, the proven synergy of
De-Soldering Wire and the
AirBath™ preheating systems make it
a natural for any electronic
benchtop where prototyping and/or
rework of PCB's is performed.
