Handling Procedures for Syringes of Frozen Underfill Encapsulants
|
From Emerson & Cuming
Recommendations: The follow is recommended for storage and handling of frozen underfill encapsulant syringes. These recommendations should be used as guidelines in handling frozen underfill syringes because each product is unique and the thawing time and process may vary. We recommend trial evaluation on the specific product and package for the development of internal manufacturing procedures. Storage and Handling Procedures: 1. Underfills are packaged in syringes, frozen, and shipped in dry ice to avoid thawing. arrival, dry ice may not be evident due to evaporation. 2. Special care should be taken with underfills stored at -40°C/°F. To prevent breakage, handle the syringe by the tip or shoulder area. The package may break if handled by the barrel at -40°C/°F. Remove the frozen underfill syringes from 40°C/°F freezer and place in a refrigerator at 0°C/32°F for 10-20 minutes. This will allow the syringes of underfill to become acclimated to the warmer temperature and prevent formation of air pockets in the material due to the expansion of the plastic syringe.
