Video: Hot Air Pencil SMD Soldering With Paste

More Details:

The Hot AirPencil Presents Many Advantages of the Traditional Soldering Iron: As mentioned above, first and foremost, the hot air pencil is completely non-invasive because provides precision, pin-pointed, yet non-contact and low-velocity hot air directly to the individual component leads. But that's hardly the beginning:

Hot Air Pencil vs the Soldering Iron: There are many additional advantages of the hot air pencil over a the traditional contact soldering iron. Below are a few:

a.) there is absolutely no opportunity to bend/deform delicate SMD leads or scratch/damage delicate pads which is a common occurence with traditional soldering  irons;

 b.) the air pencil, unlike the soldering iron, allows no opportunity for introducing contamination into your assembly such as dirt, grime, residual flux, adhesives and more;

 c.) the air pencil works with either Lead-free or traditional leaded solder alloys because it never contacts the pad and/or solder unlike traditional soldering tips which must be carefully segregated between lead-free and leaded alloys at the bench;

 d.) with the air pencil, there is no accidentally bumping or moving your carefully placed SMD which is also a drawback with the soldering iron which can misalign the chip after it is placed because it contacts the chip;

 e.) the air pencil excels where the traditional soldering iron fails in preparing or "touching up" pads, for while a contact iron can leave tags or "ice-cycles" which compound co-planarity problems, the hot air pencil hot levels and leaves a smooth pad; and

 f.) perhaps most noteworthy, the soldering iron is very damaging to ceramic chip capacitors due to its immediate conductive application of high temperature directly to the leads setting up unequal thermal expansion conditions between the chip and its leads resulting in unacceptable cracking and fissuring conditions. The hot air pencil, with its convective nature, essentially eliminates this problem altogether.

Touch-Free, Hot Air Soldering Presents Many Advantages Over Traditional Contact Soldering Irons

Ceramic Capacitors Must Always Be Soldered With "Touch-Free" AirPencils, Never With Soldering Irons, To Prevent Thermal Shock, & Chip Cracking.

So Many Features! Rewriting all the rules, the engineers at Zephyrtronics pulled out all the stops when designing the ZT-2-MIL AirPencil’s hand-piece/pencil. Consider the following 3 issues:

1) The system delivers up to 530ºC at the Air Tip exit and, yet is powered by only an extra-safe, extra-low 24 volts (Be sure to investigate the high voltages of our so-called "competition").

2) It's featherweight and pencil-thin hand piece is, to our knowledge, now the lightest and thinnest AirPencil ever, making soldering a joy rather than a drudge.

3) Our precision air velocity control dial has 3 full rotations for the finest of adjustments ---separating it from all other high-velocity so-called "hot air tools" which can and do blow tiny chips away during reflow and/or scatter solder balls up under IC's. Our unique 3-turn dial puts you in control while you work.

The AirPencil & Solder Paste! What a Great Combination: And because of the extra low adjustment to the air velocity, you can now, at long last, work successfully with solder paste for your high quality reflow creating solder joints replete with fillets at the toes, heels and sides of the SMD's. Wait until you experience the difference!  Did we say solder paste reflow at the bench? Want to see how to use the ZT-2-MIL AirPencil? Just check out our color pictorial process page, "SMD Soldering Made Easy at the Bench".

The Zephyrtronics ZT-2-MIL AirPencil belongs at every work bench where critical SMT rework is being performed. And for enhanced results, it is recommended that the system be used in concert with any of our now world-famous ZT-1 AirBaths for quality thermal profiles through pre-heating.

 The ZT-2-MIL Belongs at Every Bench Where SMT Soldering & DeSoldering Is Performed. This is the Tool You Want to Have at Your Fingertips.
