Choosing the right AIM solder for your application.

Different assembly processes call for different solder forms and chemistries. Use this quick guide to narrow down what you need, or download the full AIM Solder Selection Guide for detailed alloy and flux recommendations.

SMT / Reflow Assembly

For surface-mount assembly with reflow soldering, AIM solder paste is the standard. Choose a no-clean paste like AIM M8 for most general production work, or step up to the REL series for high-reliability applications in automotive, aerospace, and medical electronics. Select water-soluble pastes when your line includes an aqueous cleaning step.

Recommended

AIM M8 · AIM REL Series · AIM Glow Core wire for rework

Wave & Selective Soldering

Wave and selective soldering machines run on bar solder and liquid flux. AIM SAC305 bar solder is the most common lead-free choice; Sn63/Pb37 remains standard where leaded processes are still in use. Pair the bar with a low-solids no-clean liquid flux like AIM FX16 for clean, residue-controlled joints.

Recommended

AIM SAC305 bar · AIM FX16 flux

Hand Soldering & Rework

For hand soldering, rework, and touch-up, cored wire is the right form. Match the flux core to your cleaning process: no-clean wires like AIM Glow Core leave minimal residue; water-soluble wires like WS482 are ideal where boards will be cleaned anyway. For difficult oxidized surfaces, use higher-activity wire like AIM OAJ flux core.

Recommended

AIM Glow Core · AIM OAJ · AIM WS482

Frequently Asked

AIM Solder, answered.

Direct answers to the most common questions about AIM Solder products, our authorized distributor relationship, and shipping. If you don't see your question here, our technical team responds within one business day.

Is SMTsupplies an authorized AIM Solder distributor?

Yes, AIM technical datasheets and Safety Data Sheets are available on request and are typically delivered within the same business day. Many of these documents are also available directly from the AIM Solder Resources section on this page., SMTsupplies is an authorized distributor of AIM Solder products. We purchase directly from AIM, ship genuine materials with current date codes, and provide full traceability and warranty coverage on every order.

What AIM Solder products does SMTsupplies stock?

SMT Supplies is the largest single-stocking location distributor in the country. We stock the AIM Solder products most commonly used in electronics manufacturing, including AIM solder paste in all alloys; Lead Free, REL61, SAC305, SN100C, and SN63/PB37 (both no-clean and water-soluble). AIM bar solder in SAC305, REL61, SN100C and SN63/PB37.

What's the difference between no-clean and water-soluble solder?

No-clean AIM solder leaves a minimal, non-corrosive residue that does not require cleaning after assembly, making it ideal for production lines without an aqueous cleaning step. Water-soluble AIM solder leaves a more active residue that must be cleaned with deionized water after soldering, but it generally provides stronger flux activity.

Which AIM no-clean solder paste is best for SMT assembly?

AIM M8 is the most widely used AIM solder paste for general SMT assembly because it offers strong stencil printing performance, good wetting, and clean reflow with low residue. For high-reliability applications such as automotive and aerospace electronics, AIM REL series pastes are recommended for their improved thermal cycling and mechanical shock performance.

What is AIM REL solder and when should I use it?

AIM REL is a family of high-reliability lead-free solder alloys engineered to outperform standard SAC305 under thermal cycling and mechanical stress. REL alloys are typically specified for automotive electronics, aerospace, military, and other high-reliability applications where long-term joint integrity is critical.

Does AIM Solder offer lead-free options?

Yes, AIM offers a full range of lead-free solder products including SAC305 paste, wire, and bar, plus the proprietary REL series of high-reliability lead-free alloys and SN100C. AIM was an early developer of lead-free alloy technology and continues to expand its lead-free product portfolio.

What is the shelf life of AIM solder paste?

AIM solder paste typically has a shelf life of six months when stored refrigerated at 0–10 °C (32–50 °F), per the manufacturer's recommendation. Always check the date code on the specific container and refer to the product datasheet for exact storage requirements.

Does SMTsupplies offer same-day shipping on AIM Solder?

Yes, AIM Solder orders placed before 2pm ET on a business day ship the same day from our US warehouse, subject to stock availability. Solder paste ships in insulated packaging with cold packs to maintain proper temperature during transit.

Can I get a quote for bulk AIM Solder orders?

Yes, SMTsupplies provides volume pricing, contract pricing, and scheduled-release support for AIM Solder customers. Contact our sales team with your part numbers, quantities, and delivery requirements to receive a quote, typically within one business day.

Does SMTsupplies provide AIM datasheets and SDS documentation?

Yes, AIM technical datasheets and Safety Data Sheets are available on request and are typically delivered within the same business day. Many of these documents are also available directly from the AIM Solder Resources section on this page.
