Indium 8.9HF SAC305 Lead-Free Solder Paste 600g - No Clean Type 4
Indium 8.9HF SAC305 Lead-Free Solder Paste 600g - No Clean Type 4
Indium 8.9HF PASTEOT-800495-600G is a SAC305 no-clean solder paste supplied in a 600g cartridge with Type 4 powder and 88.5% metal loading. It supports lead-free SMT stencil-printing processes where paste transfer, oxidation resistance, and post-reflow probe testability are important. Select the cartridge and delivery hardware for your printer rather than assuming it fits a syringe dispenser.
Minimum order: 1 cartridge. Overnight shipping only for this temperature-sensitive listing.
Best Uses / Applications
For electronics manufacturers and EMS providers evaluating SAC305 stencil-printing processes, including fine-pitch, BGA, CSP, and QFN assemblies. Validate stencil release, reflow, residue acceptance, and voiding on the actual assembly. Automotive, medical, and aerospace use requires application-specific qualification; the paste name alone does not establish suitability.
Key Features
- No-clean flux with halogen-free test results described in the manufacturer data sheet.
- Manufacturer-reported low voiding and oxidation resistance, not a guaranteed defect rate on every assembly.
- Air-reflow formulation with clear, probe-testable residue.
- Cartridge packaging for compatible paste-delivery and printing equipment.

Storage and Process Guidance
Store cartridges tip down. Allow sealed material to reach ambient working temperature before use. The manufacturer generally specifies removal from refrigeration at least two hours before use, but actual equilibration depends on container size; verify paste temperature. Mark opening date and time. Use the applicable profile as a starting point and validate the board and component temperatures. Do not infer regulatory or customer approval from the SAC305 designation.
Format Comparison
| Format | Selection consideration |
|---|---|
| 600g cartridge, this listing | For compatible cartridge delivery and printing systems; confirm hardware fit. |
| 500g jar | Alternative packaging for jar-based printing workflows; confirm exact order code and availability. |
| Dispensing syringe | Requires an appropriately specified dispensing formulation and hardware; not automatically interchangeable with this cartridge. |
Frequently Asked Questions
What is the exact part number?
This listing is PASTEOT-800495-600G, the 600g SAC305 Type 4 configuration.
Is this intended only for dispensing?
No. Cartridge packaging does not make a paste dispensing-only. Indium lists cartridge and enclosed-print-head packaging; verify the formulation and delivery hardware for your intended process.
Does no-clean mean cleaning is never needed?
No. Determine whether residue may remain from your validated assembly and customer requirements. Qualify a compatible cleaning process if removal is necessary.
What is the refrigerated shelf life?
The SAC305-family PDS 98485 R27 lists 12 months for unopened material below 10°C. The lot label and applicable configuration documentation must be checked; do not substitute figures from other 8.9HF alloy or powder variants.
Does Type 4 guarantee performance at a particular component pitch?
No. Aperture dimensions, stencil thickness, paste release, and process conditions must be evaluated together.
Why is overnight shipping specified?
This listing requires overnight shipping for temperature-sensitive material. Follow the supplier's transport and receipt instructions; overnight service is not itself proof of continuous refrigeration.
