    • A method of manufacturing a thin support package structure includes the steps of: preparing a support plate formed with a plurality of grooves adjacent to an outer rim thereof, forming a releasing material layer on the support plate; forming a first circuit layer on the releasing material layer so as to form a thin circuit board; forming a dielectric layer on the releasing material layer; forming a plurality of openings in the dielectric layer; forming a second circuit layer on the dielectric layer; forming connection plugs by filling the openings; forming a solder mask on the dielectric layer; forming a plurality of notches on the lower surface of the support plate to communicate with the grooves, respectively; and removing the central part of the support plate between the notches and the central part of the releasing material layer on the support plate.
    • 制造薄支撑包装结构的方法包括以下步骤:制备形成有与其外缘相邻的多个槽的支撑板,在支撑板上形成释放材料层; 在所述释放材料层上形成第一电路层以形成薄电路板; 在释放材料层上形成介电层; 在介电层中形成多个开口; 在所述电介质层上形成第二电路层; 通过填充开口形成连接插头; 在电介质层上形成焊料掩模; 在所述支撑板的下表面上分别形成多个凹槽以与所述凹槽连通; 并且在支撑板上的切口和释放材料层的中心部分之间移除支撑板的中心部分。
