摘要:
Disclosed is an electronic component package 100 including a circuit board 10, an electronic component 20, and an adhesive layer 30. The circuit board 10 is provided with an electrically-conductive conductor post 16 which is buried in a base member 12, and a solder layer 18 which is provided at the front end 13 of the conductor post 16 while exposed from a surface 121 of the base member 12. An electrode pad 24 having a metal layer 22 mounted thereon is provided on the main surface 26 of the electronic component 20. The adhesive layer 30 contains a flux activating compound, and bonds the surface 121 of the base member 12 and the main surface 26 of the electronic component 20. Then, the metal layer 22 and the solder layer 18 are metal-bonded.

摘要:
Disclosed is an electronic component package (100) including a circuit board (10), an electronic component (20), and an adhesive layer (30). The circuit board (10) is provided with an electrically-conductive conductor post (16) which is buried in a base member (12), and a solder layer (18) which is provided at the front end (13) of the conductor post (16) while exposed from a surface (121) of the base member (12). An electrode pad (24) having a metal layer (22) mounted thereon is provided on the main surface (26) of the electronic component (20). The adhesive layer (30) contains a flux activating compound, and bonds the surface (121) of the base member (12) and the main surface (26) of the electronic component (20). Then, the metal layer (22) and the solder layer (18) are metal-bonded.
摘要:
A catheter (10) has a main lumen (20), and sub-lumens (30) each of which having a diameter smaller than that of the main lumen (20). The plurality of sub-lumens (30) are arranged along a circumference of the main lumen (20) in a discrete manner, and each of the sub-lumens (30) has an operating wire (40), fixed to the distal end section (15) of the catheter (10), laid therethrough in a freely slidable manner. By pulling the operating wire(s) (40) respectively laid through the sub-lumens (30), the distal end section (15) of the catheter (10) may be bent towards the pulled operating wire(s) (40) laid therethrough.
