Key Features
- SAC305 lead-free alloy: Match the alloy to the assembly's approved soldering requirements.
- Type 4 powder at 88.5% loading: Specify the full formulation rather than ordering by flux-family name alone.
- Low-voiding product family: Indium's data sheet identifies low BGA, CSP, and QFN voiding; actual results depend on the assembly and process.
- Stencil-printing performance: The product-family sheet describes high transfer efficiency through small apertures and resistance to hot and cold slump.
- Halogen-free no-clean flux: The sheet identifies clear, probe-testable residue and ROL0 classification.
- 500g jar: Suitable for replenishing paste in jar-fed stencil-printing workflows.
Industries & Applications
- Electronics manufacturing: SAC305 SMT assembly for industrial, commercial, and consumer electronics.
- Contract electronics manufacturing: Stencil-printing workflows using the specified paste formulation.
- Prototyping and process development: Print and reflow trials with controlled paste handling.
- High-reliability assembly: Use only within approved process and cleanliness requirements. This paste listing does not by itself establish automotive, medical, or aerospace qualification.
Jar Format vs. Cartridge Format
| Consideration | This 500g Jar | Cartridge Packaging |
|---|---|---|
| Paste delivery | Paste transferred from the jar to the printing process | Equipment-specific cartridge delivery |
| Purchasing check | Confirm 800495-500G, Type 4, 88.5% metal loading | Confirm the exact cartridge SKU, formulation, size, and equipment compatibility |
| Interchangeability | The same flux-family name does not establish identical loading, powder type, or equipment suitability. | |
Storage & Handling
The supplied Indium8.9HF product-family sheet lists an unopened shelf life of 12 months below 10°C and 30 days maximum below 25°C. These are storage conditions, not a promise of remaining shelf life at delivery. Use the expiration date on the supplied lot and follow current manufacturer instructions.
Allow the sealed jar to reach ambient working temperature before opening. The sheet generally recommends removal from refrigeration at least two hours before use and notes that warming time varies with container size. Label jars with their opening date and time; do not assume the unopened shelf-life limits apply after opening.

Frequently Asked Questions
What formulation is this jar listing?
PASTEOT-800495-500G is listed as Indium 8.9HF, SAC305 alloy, Type 4 powder, 88.5% metal loading, in a 500g jar. Confirm that complete specification against your approved purchasing record.
Is 800494 an interchangeable alternative?
Interchangeability has not been established. Confirm the exact part number, packaging, powder type, and metal loading with your supplier before substituting another SKU.
What does 8.9HF mean?
It identifies Indium's no-clean flux family; HF denotes the halogen-free formulation. The family sheet lists EN14582 testing and ROL0 flux classification.
Is this paste suitable for every fine-pitch component?
No universal component-size or pitch qualification is implied. Match Type 4 powder to stencil geometry, aperture design, printing parameters, and the validated reflow profile.
Does no-clean mean cleaning is never required?
No. Determine residue acceptability against the assembly's electrical, cleanliness, and downstream coating requirements. A no-clean designation does not replace process qualification.
What shelf life does the manufacturer sheet list?
For unopened containers, the supplied product-family sheet lists 12 months below 10°C or 30 days maximum below 25°C. Follow the supplied lot expiration date; these limits are not guaranteed remaining shelf life when purchased.
How long should a refrigerated jar warm before use?
The sheet generally recommends at least two hours out of refrigeration, but warming time varies with container size. Keep the jar sealed until it reaches ambient working temperature and follow the current handling instructions.
Why is overnight shipping required?
This listing requires overnight shipping for temperature-sensitive solder paste. Arrange receipt and refrigerated storage promptly, following the manufacturer's instructions and supplied lot label.
