Inventec Ecorel Free 305-16 solder paste is a no-clean, lead-free paste made with the popular SAC305 alloy. It gives you strong, reliable joints on modern SMT lines. In addition, it wets well on a wide range of board finishes, including OSP. This makes it a safe, stable choice for everyday production.
Why choose 305-16 solder paste?
Poor wetting leads to weak joints and costly rework. For this reason, Inventec designed this paste to spread and bond evenly, even on tricky OSP boards. The alloy melts at 217°C, so it suits standard lead-free reflow profiles.
The flux leaves only a small amount of residue. This residue does not conduct and does not corrode. As a result, most users can skip cleaning after reflow and save time on the line.
Key features
- SAC305 lead-free alloy
- Melting point of 217°C
- Type 3 powder for standard fine pitch printing
- No-clean flux with low, safe residue
- Excellent wetting on OSP and metal finishes
- Good slump resistance and a wide process window
- Supplied in a 500 g jar
Where to use 305-16 solder paste
This paste suits a wide range of electronics work. For example, it is a good fit for:
- High-density circuit boards
- General SMT assembly
- Boards with OSP, ENIG or tin finishes
- Products that must meet RoHS rules
Because it resists slump, the printed paste keeps its shape between print and reflow. This helps you avoid bridging on tight pitch parts. It also means you get more good boards per run.
Tips for best results
First, let the jar reach room temperature before you open it. Next, stir the paste gently to get an even mix. Then print and place your parts. Finally, reflow using a profile that suits your board and oven. Always check the datasheet for full storage and profile details.
