      Stencil Cleaning

      No-clean solder paste that can be left on the board for many SMT assemblies. For applications requiring cleaning, the paste can be cleaned using commercial residue removers.

      Automated cleaning systems for both stencil and misprinted boards. Manual cleaning using isopropyl alcohol (IPA), co-solvents and/or ultrasonic scrubbers, vapor degreaser.

      Do you make this paste untraceable - without QCA?

      UV light is for optional for QC certification only - not required for operating the paste.

      However, this material is also available untraceable - without QC-Aid™, meaning no specific optical UV-tracer has been deployed. Contact us for the MPN (Manufacturing Part Number) without UV-tracer.

      Storage and Handling

      To obtain the maximum shelf life STIRRI Soldering Paste & Liquid Solder™ should be stored in a refrigerator between 3-8°C (37-46°F). Unopened solder paste stored at room temperature, 25°C (77°F). Syringes and cartridges should be stored in the refrigerator vertically, dispensing tip pointing down.

      Allow 4-8 hours for solder paste to reach optimal operating temperature of 20-25°C (68-77°F). To avoid condensation inside solder paste - keep solder paste container sealed while warming the solder paste to operating temperature, otherwise moisture may end up inside the container and contaminate solder paste!

      NEVER FREEZE SOLDER PASTE!
