- Printer Operations
Stencil printer does not require any specific optimization, should be fully adjustable based on standard in-house process requirements, including high-speed printers; Print Speed: 20-200 mm/sec (add pressure for speed) Squeegee Pressure: 70-540 g/cm of blade (add for speed) Stencil Vac/Wipe: Every 10-25 prints or as necessary; Automated and vacuum cleaning systems for both stencil and misprinted boards. Manual cleaning using Isopropyl alcohol (IPA), co-solvents and/or ultrasonic scrubbers, vapor degreaser.
- Packaging Information
- Options with various viscosity and metal load for stencil printing and dispensing applications:
- Printing
- Jars, 1/4 NPT nozzle cartridges
- Dispensing
- Syringes, ProFlow cassettes
- Certifications and Compliance
- REACH (Europe)
- Shelf LIfe
Refrigerated storage at 5-7°C will prolong the solder paste shelf life to no less than 6 months. Solder Paste should be allowed to reach ambient temperature, normalize for about 6-8 hours before use. Tacky flux has 24 months shelf life stored in room temperature. Refrigeration won't extend shelf life. Normalize for 4-6 hours if stored refrigerated. Paste/flux in syringes and cartridges should be kept vertically, dispensing tip pointing down.. Note :NEVER FREEZE SOLDER PASTE / FLUX!
