Sn62/Pb36/Ag2 Solder Paste

Sn62 / Pb36 / Ag2 · Near-eutectic Leaded · 30g Syringe

⚠ LEADED

DANGER · CONTAINS LEAD — For RoHS-exempt applications only. Not for consumer electronics under EU RoHS Directive 2015/863. See Section 7 for full safety information.

WHY 2% SILVER — plain tin-lead solder dissolves thin silver metallization during reflow and erodes the termination. Pre-loading the alloy with 2% Ag raises its silver activity close to saturation and removes that driving force. Use it on Ag / Ag-Pd terminations — chip resistors and MLCCs, LTCC and thick-film silver conductors, silver-plated pads, ceramic and RF modules. For ordinary tin-lead work, use Sn63/Pb37 (TSP-PB37-30G) instead.

After Use: Remove the needle, tighten the cap, and store upright in the refrigerator. Mark the open date — best used within 2 weeks of opening. Do not use past the EXP date. Store away from food, children, and pregnant individuals.

TROUBLESHOOTING

Paste hard to dispense

Paste too cold. Let the syringe warm at room temperature (20–25°C) for 1–2 hours. Never apply heat.

Joints appear dull or grainy

Peak temperature too low, or cooling too fast. Increase peak to 220°C and allow natural cooling.

Excessive solder balls / spatter

Moisture absorbed or peak too high. Allow paste to fully warm before use. Reduce peak to within 215–225°C window.

Paste dried at the nozzle

Clear with a toothpick or replace the needle. Cap the syringe immediately after every use to prevent oxidation.

HOW TO USE

Warm the syringe

Remove from the refrigerator and let it sit at room temperature (20–25°C) for 1–2 hours. Never microwave or apply direct heat.

Cold paste affects flow and joint quality

Prepare your workspace

Work in a well-ventilated area with active fume extraction. Wear nitrile gloves and safety glasses. Clean PCB pads with 99% IPA and let dry completely.

⚠ Lead fumes are harmful — always extract

Attach the dispensing needle

Screw the needle onto the syringe tip. Use 22G–25G for fine-pitch (<0.5mm); 18G–20G for standard pads and through-hole.

Apply paste to pads

Apply even pressure in small amounts — just enough to cover the pad. Avoid bridging adjacent pads. Wipe excess immediately with IPA-soaked lint-free wipe.

Less is more — start small

Place the components

Use tweezers or a vacuum pen to place components. Paste tackiness holds them in place before reflow.

Reflow soldering

Follow the reflow profile; peak 220°C, must not exceed 235°C. Maintain TAL (above 179°C) for 30–60 seconds. Allow board to cool naturally to room temperature.

⚠ Active fume extraction required during reflow

Inspect & wash hands

Good joints look bright and silvery with complete wetting. No-clean flux residue is non-conductive — no cleaning required. Wash hands thoroughly with soap and water before eating or touching face.

⚠ Hand washing is mandatory after handling lead
