Indium 8.9HF SAC305 Lead-Free Solder Paste 600g - No Clean Type 4
Indium 8.9HF SAC305 Lead-Free Solder Paste — 600g Cartridge | PASTEOT-800495-600G
Indium 8.9HF (SKU: PASTEOT-800495-600G) is a halogen-free, no-clean lead-free solder paste formulated with SAC305 alloy (96.5Sn/3.0Ag/0.5Cu) and Type 4 powder at 88.5% metal load, packaged in a 600g cartridge for use with pneumatic and enclosed dispensing systems. Engineered for RoHS-compliant SMT assembly, 8.9HF delivers exceptional print definition, extended tack time, and low voiding on BGA, QFN, and fine-pitch components. Ships overnight only due to refrigeration requirements.
Minimum order: 1 cartridge. Ships overnight only (temperature-sensitive).

Key Features
- SAC305 lead-free alloy — 96.5Sn/3.0Ag/0.5Cu with 217–220°C melting range; RoHS and REACH compliant
- 600g cartridge format — designed for pneumatic and enclosed dispensing systems; ideal for automated or high-volume SMT printing
- Type 4 fine powder (20–38μm) — precise paste deposition on fine-pitch components, BGA, CSP, QFN, and LGA packages down to 0.4mm pitch
- Low voiding performance — optimized flux chemistry minimizes voiding on BGA and QFN pads for high-reliability assemblies
- Halogen-free no-clean flux — <900ppm Cl/Br; meets J-STD-004 halogen-free classification; no post-reflow cleaning required in most applications
- Extended tack time — maintains component placement stability during high-speed, high-mix SMT production
- ANSI/J-STD-004 & J-STD-005 compliant — meets all applicable IPC flux and solder paste specifications
Industries & Applications
- Electronics manufacturing — automated SMT assembly lines using lead-free SAC305 paste
- Automotive electronics — RoHS-compliant solder paste for ADAS, powertrain, and body control module assemblies
- Medical device manufacturing — high-reliability fine-pitch assembly with halogen-free no-clean flux
- Aerospace and defense electronics — J-STD-004 compliant, halogen-free flux chemistry for fine-pitch and BGA assembly
- Contract electronics manufacturing (CEM/EMS) — high-mix SMT production requiring consistent print performance

Frequently Asked Questions
What dispensing equipment is compatible with the 600g cartridge?
The 600g cartridge is designed for pneumatic syringe dispensers and enclosed paste dispensing systems. It is not intended for open-jar squeegee printing. Ensure your dispensing system accepts 600g cartridges and is compatible with SAC305 Type 4 solder paste before ordering.
Does Indium 8.9HF require post-reflow cleaning?
No — 8.9HF is a no-clean formulation. Post-reflow residue is minimal, non-corrosive, and electrically safe. No cleaning is required in most applications.
What is the shelf life and storage requirement?
Indium 8.9HF has a 6-month shelf life when stored refrigerated at 2–10°C (35–50°F). Allow to reach room temperature before use. Do not use paste that has exceeded its shelf life.
Why does solder paste require overnight shipping?
Solder paste is temperature-sensitive and must be shipped refrigerated to preserve flux activity, viscosity, and shelf life. Refrigerate immediately upon receipt and allow to reach room temperature before use.
