15 Feb 2007 It should be as low as possible to scrape the stencil clean of solder paste particles when printing. The amount of pressure is determined by the printing speed and stencil type. The printing speed is usually recommended by paste manufacturer. Usually the solder paste manufacturer only gives guideline to
Handling Guidelines. Temperature Stable Solder Paste. February 2015. HANDLING. Storage: It is recommended that the solder paste be stored at of the paste. Stirring: To restore fresh solder paste to its specified rheology, it can be stirred gently for 1 – 2 minutes before being applied to the printer. Always use a
Guidelines. Solder Paste Storage. • Indium Corporation solder paste is refrigerated or frozen after manufacturing and shipped cold, often with a cold pack. This helps keep the For product-specific storage requirements and shelf life information, please elevated viscosity, resulting in poor print transfer. • Working life of
Below are the general guidelines to be used for handling ALPHA® Solder Pastes. Typical no-clean solder paste shelf life is 6 months, water-soluble paste ranges from 3-6 months in a refrigerated Best practices for solder past printing are to maintain the temperature inside the printer between 22°C – 29°C, 40% -.
