Provided is a thermal type airflow volume meter improving measurement accuracy, a method for manufacturing the same, and an adhesive sheet for use therein, the adhesive sheet divided into at least two or more per adherend and having a thickness of approximately 0.1 mm or less is divided to correspond to a shape of the adherend and generates or increases adhesion or stickiness by external energy.

Adhesive sheet, method for manufacturing semiconductor device using same, method for manufacturing thermal airflow sensor using same, and thermal airflow sensor

An electronic equipment is capable of improving falling down shock resistance or impact resistance in an electronic equipment and of improving reliability of a solder joint in a semiconductor device die-bonded Si chip or the like to which thermal shock causing large deformation may act, bump mounting of BGA, CSP, WPP, flip-chip and so forth, a power module acting large stress and so forth. The electronic equipment has a circuit board and an electronic parts to be electrically connected to an electrode of the circuit board. The electrode of the circuit board and an electrode of the electronic part are connected by soldering using a lead free solder consisted of Cu: 0-2.0 mass %, In: 0.1-10 mass %, and Sn: remaining amount.
