The method of making a low dielectric constant and CCL

The present invention relates to a low dielectric constant and a manufacturing method of CCL. Belonging to CCL technology. The present invention provides a low dielectric constant and the alkali method to obtain cristobalite, and to improve the composition of the resin mixture CCL CCL obtain a low dielectric constant. The present invention solves a method of a low dielectric constant has been obtained by using a low dielectric constant resin or resin by modification, and the use of more economical, convenient to add a low dielectric constant inorganic filler, particularly the use of prepared ore vein Shi Ying cristobalite powder as an inorganic filler composition CCL method for reducing the dielectric constant.
