Handling and Storage Introductions
1) Refrigerate pastes at 0~10 °C to prolong shelf life; normal shelf life is 6 months from production date (sealed jars).
(2) Keep away from direct sunlight.
Use (Sealed)
(1) Allow pastes to reach ambient temperature prior to use, 3 - 4 hrs. Do not heat or raise temperature abruptly.
(2) Mix paste well with plastic spatula for 1-3 mins before use. Mixing time depends on tool type.
Use (Opened)
(1) At first add 2/3 jar of solder paste onto the stencil. Do not add more than 1 jar.
(2) Add paste a little at a time.
(3) It is recommended to finish fresh paste within 24 hrs. To maintain paste quality, make sure not to store used paste and fresh paste in the same jar.
(4) At the beginning of the next day, use leftover solder paste from the previous day by mixing with new, unopened paste at a ratio of 1:2 (opened: new), adding a little at a time during printing.
