    Abstract: The present invention increases real estate by providing non-annular lands which do not completely encircle the through holes. The non-annular lands are non-annular, that is they do not extend 360.degree. around the through hole. Preferably the non-annular lands contact no more than one side of the through holes thereby providing real estate not otherwise available using conventional lands. The present invention also relates to a method for producing such Non-annular lands.

    Abstract: PURPOSE: A landless printed circuit board is provided to implement a high density wiring without a separate bump pad by directly interlinking a conductive bump and a circuit. CONSTITUTION: A landless printed circuit board comprises an insulating layer(100), a circuit pattern(200), and a conductive bump(300). The circuit pattern is formed in both sides of the insulating layer. The circuit pattern is formed by using a single method among a tenting, a M-SAP(Modified Semi-Additive Process), a SAP and an ink jet printing method. The conductive bump is formed within the insulating layer. The conductive bump electrically interlinks a circuit pattern in both sides of the insulating layer. The conductive bump is directly connected to the circuit pattern without the bump pad.

    Abstract: PROBLEM TO BE SOLVED: To protect a semiconductor component with an inexpensive and simple method from a discharge generated from a piezoelectric element owing to the pyroelectric effect in a process of a flow soldering. SOLUTION: An electronic device includes, for instance, a printed circuit board soldered with the use of a solder jet flow, a semiconductor component provided on the printed circuit board, and a piezoelectric element provided on the printed circuit board. Further, the electronic device includes a reference potential pattern and a land. The reference potential pattern imparts a reference potential to at least one of the semiconductor component and the piezoelectric element. The land is provided between the semiconductor component and the piezoelectric element, connected to the reference potential pattern, and formed by exposing the wiring part from a solder resist layer of the printed-wiring board. This causes the discharge current generated in the piezoelectric element owing to the pyroelectric effect in a process of the flow soldering using the solder jet flow to flow on a discharge channel formed by the piezoelectric, the land, the reference potential pattern, and the solder jet flow.

    Abstract: PROBLEM TO BE SOLVED: To provide a printed circuit board capable of certainly preventing the damage of a conductor pattern caused by a terminal.
    SOLUTION: A printed circuit board 1a includes a substrate 2, a conductor pattern 6, a through-hole 4, and a non-conductor portion 5. A lead line 22b of a resistor 22 mounted on a printed circuit board 1a is inserted in the through-hole 4. The lead line 22b is bent so that the line protrudes toward the surface 2a of the substrate 2 and the line comes near the surface 2a of the substrate 2. The resistor 22 is attached to the printed circuit board 1a. The non-conductor portion 5 is formed substantially into the shape of a fan which expands with the through-hole 4 at the center as it is closer to the leading end of the lead line 22b. The bent lead line 22b is arranged in the non-conductor portion 5. The non-conductor portion 5 prevents the lead line 22b from coming into contact with the conductor pattern 6 and damaging the conductor pattern 6.
