The present invention relates to a method and apparatus for mounting an electronic part (11) on a circuit board (28). When the part is mounted, a distance between the under surface of a part maintaining section (12) and the circuit board (38) is measured. Determination that the electronic part (11) is normally mounted on the circuit board (28) is made by comparing the measured distance with the thickness of the electronic part (11) measured in advance.

A carrier band of electronic parts which can carry electronic parts such as IC packages in good protected condition without spoiling the convenience of a carrier tape having convexities and sticking tape. An electronic parts carrier band T which includes a flexible band (10) and keeps and carries longitudinally at intervals a large quantity of electronic parts (40) where each part (40) has a part body (42) and projecting portions (44) with the carrier band comprising: supporting stands (20), which are mounted longitudinally at intervals and project from the band (10); supporting faces (22), which are formed on the supporting stands (20) and support the electronic parts (40) by contacting the part body (42); opening portions (26), which are opened from the supporting faces (22) to a part of both side faces (24) of the supporting stands (20) at positions corresponding to the part bodies (42); and a sticking tape (30), which is longitudinally affixed to a back side of the band (10) including the supporting faces (22) by a one-sided sticking face (32) of the sticking tape (30), wherein a part of the sticking face (32) is exposed by the opening portions (26) and is stuck to a part body (42).

According to this invention, an electrically conducting wire provided with a solder ball is inserted through throughholes provided around the perimeters thereof with electrically conductive members such as copper foils which form printed wiring on both surfaces of an insulating substrate. One of the conductive members and the conducting wire are soldered by dipping or flow-soldering, thereby making a circuit connection across both surfaces of the substrate by causing melting of the solder ball on the conducting wire on the substrate surface not soldered.

The disclosure is directed to an electronic component supply apparatus for use in an electronic component mounting arrangement, which employs an electronic component carrier tape. The apparatus is arranged to separate a covering tape from a tape base of the carrier tape only at a position directly below a vacuum chuck for picking up the component, while the covering tape is separated from the tape base so as to be wound up at a winding speed lower than an intermittent feeding speed of the carrier tape by a predetermined pitch.
摘要:
Fabrication of an electronic circuit board is carried out by forming a predetermined number of resistors having various resistances based on a circuit design stored in a memory on a nonconductive substrate and dividing the nonconductive substrate into discrete resistors, then mounting the discrete resistors on a circuit board and testing operation characteristic thereof; and when some resistors having resistances which are not suitable to obtain a predetermined operation characteristic exist in the above-formed resistors, the resistances are corrected, and electronic circuit board having corrected accurate electric constants is obtained; and thereby a complete electronic circuit boards are fabricated by repetition of above-mentioned respective steps.

A component mounting apparatus comprises a hollow rod communicated to a source of vacuum and having a suction head for picking up generally rectangular articles one at a time by the effect of a suction force. At least one pair of finger members for clamping and releasing the articles which has been sucked onto the suction head are provided for effecting a correction in position of the article relative to the suction head. Each of the finger members has an inclined end face which is adapted to support the article sucked onto the suction head from below in engagement with the opposite lower edges of the article.
