AIM – Bar Solder
Zero defect wave soldering requires consistent solder quality. Contaminants and high oxide levels in bar solder can result in a variety of wave soldering defects such as bridging, projections, and poor wetting. To avoid these issues, AIM’s low drossing solder bar alloys provide a high purity product exceeding IPC, JEDEC and IEC requirements.
AIM Electropure™ bar solder is processed from high-quality, virgin metals in a proprietary method that removes contaminants and reduces dissolved oxides. AIM’s Electropure™ technique results in an extremely pure, low-drossing solder bar that increases throughput and decreases defects.
Key Features
- Low Oxide Content
- Reduces Defects Such as Bridging and Icicling
- Lower Surface Tension than Competitive Brands
- Available in Extruded, Cast, and Margash Bars
- Produced from High Purity Virgin Metals

The Industry Standard – High purity, low dross, suited for all soldering applications
SAC305 is a lead-free alloy that contains 96.5% tin, 3% silver, and 0.5% copper. This alloy falls under the JEIDA recommendation for lead-free soldering. When used in wave soldering, AIM’s SAC305 bar solder offers far superior fluidity as compared to other alloys and makes of bar, resulting in excellent flow. AIM’s SAC305 bar solder also produces less dross than other bar solder, wets well, provides superior joint strength, and offers superior copper dissolution rates. AIM’s SAC305 bar solder is alloyed in the proprietary Electropure™ method that results in a low drossing, high wetting solder. The Electropure process reduces suspended oxides in the solder, thus reducing drossing, improving flow and reducing bridging during soldering. SAC305 may be used with most existing equipment, processes, coatings, and flux chemistries.
Key Features
- Lowest Cost Sn/Ag/Cu Alloy
- Excellent Fatigue Resistance
- Compatible with all Flux Types
- Excellent Solder Joint Reliability
- Best Wetting Sn/Ag/Cu Alloy
The Original Silver-Free SAC305
SN100C is a lead-free solder alloy that is comprised of tin-copper-nickel + germanium. The properties of SN100C offer an advantage in terms of performance and cost compared to other lead-free alloys. From automotive and aerospace to consumer and telecom, SN100C has a proven history of providing a reliable, cost-effective lead-free alloy solution.
Key Features
- Smooth, Bright Solder Joints
- Bridge-Free Soldering
- Low Cost – Does Not Contain Silver
- Reduced Copper Erosion from Holes, Pads and Tacks
- Dross Rate Similar to Tin-Lead Alloys
- Complies with IPC J-STD-006
High Purity and Reduces Drossing
Sn63/Pb37 Electropure™ is a high purity alloy that is composed of 63% tin and 37% lead. Electropure is alloyed in a proprietary method that results in a low drossing, high wetting solder. The Electropure process reduces suspended oxides in the solder, thus reducing drossing, improving flow, and reducing bridging during soldering. Sn63/Pb37 is a eutectic alloy with a melting point of 183°C (361°F). Typical applications are wave soldering and plating where Sn63/Pb37 is primarily used as a coating for corrosion protection, and as a base for soldering. This alloy is available in bar, solid and cored wire, foil, spheres, preforms, powder, solder paste, ingot, and anode form.
Key Features
- High Purity
- Reduces Drossing
- Exceeds IPC-J-STD-006 Specifications
AIM Electropure Reduces Dross Better Than Competitors
Dross Comparison of AIM Electropure Bar vs. Competitors
500 pounds of each type of alloy was heated in a wave solder pot at 500°F for 6 hours. The pot was de-drossed every 3 hours. After 6 hours the amount of dross generated from each type of solder was weighed. AIM’s bar solder has proven to reduce drossing as compared to competitive brands.
