Abstract: A circuit board structure includes a rigid circuit board, a flexible circuit board, a plurality of conductive bumps, and a plurality of spacers. The rigid and flexible circuit boards are stacked one above the other. The conductive bumps are formed between the rigid and flexible circuit boards. The spacers are formed between the rigid and flexible circuit boards and spaced apart from the conductive bumps.

Abstract: An extraction technology of a Xiao-yao-drink includes a medicine preparing step of preparing herbal medicines, a pulverizing step of pulverizing the herbal medicines to produce medicinal solid particles, a liquid extracting step of adding the medicinal solid particles into an extraction liquid to dissolve the medicinal solid particles in the extraction liquid, an ultrasonic extraction step of impacting the medicinal solid particles in the extraction liquid by concentrated ultrasonic waves to crush the medicinal solid particles into medicinal molecules, and a centrifugal filtering step of filtering the medicinal molecules from the extraction liquid by a strainer cloth to produce a medicinal extract which constructs a Xiao-yao-drink product. Thus, the extraction technology uses an ultrasonic extraction procedure to crush the medicinal solid particles into medicinal molecules by concentrated ultrasonic waves to efficiently increase the active component of the herbal medicine.
