then placed next to a 99.99% pure cathode sheet and an electric current is run through the electrolytic bath. The impure and con- taminated anode depletes into the bath. Only the pure desired alloy grows on the cathode sheet, while all other contaminants, metallic and non-metallic, precipitate out into the bottom of the tank as a sludge. The resulting tin/lead or tin cathode metal is 99.99% pure. This highly pure metal is then adjusted based on the desired alloy. Unlike reclaim and virgin-grade solders, this process results in less impurities and assures batch- to-batch consistency.
Beyond Standard
Through the electrolytic process, Metallic Resources can obtain triple zeroes of purity, whereas J-STD-006 only calls for electronic grade solder having single or double zero purity. With less contaminants, elec- trolytic solder from Metallic Resources features lower viscosi-
AUV Intros Mini UV LED Curing
Conveyor LEBANON, IN — American Ultraviolet has introduced a new Mini UV LED conveyor system that’s ideal for curing inks, coat- ings and adhesives, including heat sensitive films. It’s also the perfect solution for small sub- strate production, and for color matching and testing in labora- tories. This new LED system cures by using 365, 375, 395 and/or 405 nm wavelengths. The Mini UV LED curing
conveyor features user-friendly touchscreen controls and plugs into standard outlets. It’s avail- able with a 3 or 6 inch wide Phoseon LED curing head, is lightweight, and adds no heat to substrates. Since 1960 American Ultra-
violet has focused on providing the highest quality ultraviolet equipment at a fair price. With a full staff of electrical, mechanical and controls engineers, and in- house metal fabrication, assem- bly, and testing, American Ultraviolet designs and builds standard and custom UV Curing solutions customers need. American Ultraviolet is head- quartered in Lebanon, Indiana, has a sales office located in Torrance, California, and offers worldwide sales and support. All equipment is manufactured in the USA.

ty, lower surface tension, and greater fluidi- ty. This results in brighter, shinier solder joints, superior wetting and wicking, fewer defects, and significant reductions in rework. The electrolytic process removes metal- lic and non-metallic impurities often found in “virgin metals” and reclaimed solders to pro- vide purer tin and tin/lead solder. This puri- ty results in a smaller crystalline structure which exhibits a shinier, more brilliant sol- der appearance.
Beyond these defining characteristics, electrolytic solder from Metallic Resources also yields less dross and is more sustainable than the competition. A solder that is lower in viscosity and surface tension will flow more smoothly and cause less turbulence.
What this means is less dross generation compared to all other non-electrolytic and virgin-grade solder. Less dross means less waste, resulting in
more soldered joints per pound of solder. The generated dross has less solder content for minimal solder loss, more efficient product usage, and greater economy. Finally, solder pots using electrolytic solder can be operated at lower temperatures to provide energy sav- ings, extended pot life, reduced thermal stress, and reduced potential of contamination.
