• Solder Recycling Program - Qualitek's solder recycling program provides customers with a convenient method of disposal of solder dross, solder pot waste and expired (used or unused) solder paste scrap. Our recycling is performed on site so customer receive maximum return on the settlement statement. Final payout is determined by the amount of material received and recovered. A check may be issued or credit applied towards your next purchase. Green pails, lids and labels are for use with lead-free solder and Black pails, lids and labels are for use with leaded solder scrap. Do not mix solder scrap keep separated and use the labels provide for each pail.
  • Wire Solder Solid Core

    Qualitek utilizes state-of-the-art wire extrusion and wire drawing machines to manufacture low residue/fine diameter wire solders. Many of our formulations use the latest in no-clean/low residue technology found in our solder pastes and solder fluxes. We also developed our flux core manufacturing process to eliminate flux voids and irregular wire. Formulations are available for No-Clean, Water-Soluble, Rosin Mildly Activated, Super Activated Resin, and Rosin Activated. Solid wire is also available. Qualitek wire solders meet or exceed J-STD-004B. | View Product TDS & SDS |

  • On-the-go Qualitek Delta Dispenser Packs. Convenient size and easily dispenses. Easily carried in your toolbox or keep on the rework bench. They are available in several alloys and types. | Product Specs. TDS & SDS | 
  • New! Delta Selective Solder Solid Core Wire.  A newly designed Selective Solder Solid Wire spool has been specifically designed for Selective Soldering equipment where it can distinguish between leaded and lead-free alloys based on the color of the spool. Selective Soldering is designed to selectively solder components to specific areas of printed circuit boards and molded modules when traditional wave soldering is not possible. Selective Solder Solid Wire is compatible with most selective solder equipment machines that have the vision recognition feature built in. Qualitek offers white spools for leaded alloys and green spools for lead-free alloys. Available in 8lb. spool. Current lead time is 5 weeks or sooner, will confirm once order is placed. Qualitek solid wire solders meet or exceed J-STD-006C. | View Product TDS & SDS |   Product Info. Sheet | Price varies by quantity. Products must be added to cart to see discount.

  • Periodic solder pot analysis is recommended to maintain solder pot integrity and to check for any contaminants that may have an effect on quality and solderability issues. We recommend a solder analysis every 2-3 months, depending on the amount of PCB’s processed. To best suit your needs, Qualitek offers several solder check-up programs for leaded and lead-free pots. Programs A, B, and C are for leaded pots, and programs LF-1, LF-2, and LF-3 are for lead-free pots. Subsequently, the difference between each test is the number of metals tested for. Program C and LF-3, test for the complete major impurities as specified in IPC Standards.
