Material Storage

  • Laminate should be stored flat in a cool dry environment. Avoid bending or scratching the laminate surface.
  • When possible store the laminate in the original container.
  • Prepreg should be stored flat in a cool dry controlled environment, 73℉ (23℃) or less and 50% RH or less.
  • Extended storage of prepreg should be at a reduced temperature of 41 ℉(5 ℃). Open bags of prepreg must be resealed.
    Prepreg should not be exposed to open environments for more than 8 hours total cumulatively under the above conditions or as agreed upon between user and supplier.

Laminate Surface Preparation

  • Regular Shiny Copper can be cleaned using industry standard chemical clean or mechanical clean.
  • Reverse Treat Copper should be cleaned using industry standard chemical clean.

Inner Layer Bond Treatment

  • Alternative Oxide Treatment with organic coating using a Peroxide/Sulfuric etch technology is preferred.
  • Black or Brown Oxide can be used. In the case of using Black Oxide, please check whether peel strength is acceptable for the usage.

Drying

  • Dry finished inner layers completely to remove any absorbed moisture or surface moisture.
  • A racked bake at 225 ℉(105 ℃) for 20-30 minutes is preferred. For conveyorized alternative oxide processing, some equipment may have sufficient drying capability. However, a racked bake is suggested.
