    SC200L Hardware Design 8 Storage, Manufacturing and Packaging 8.1 Storage SC200L is stored in a vacuum-sealed bag. It is rated at MSL 3, and its storage restrictions are shown as below. Recommended storage conditions: temperature 23 ± 5 °C, and relative humidity 35% ~ 60%.储 Under the recommended storage conditions, the module can be stored in a vacuum sealed bag for 12 months.
  • Page 83 SC200L Hardware Design Push the squeegee to apply the solder paste on the surface of stencil, thus making the paste fill the stencil openings and then penetrate to the PCB. The force on the squeegee should be adjusted properly so as to produce a clean stencil surface on a single pass. To ensure the module soldering quality, the thickness of stencil for the module is recommended to be 0.18 mm~0.20 mm.
