摘要： In a circuit board having lands 2 each of which has a through hole 4 through which a lead of an electrical part is inserted, the lead 3 and the land 2 being mounted in the circuit board by using lead-free solder 6, the width of the land 2 corresponding to the difference in radius between the land 2 and the through hole 4 is set to about 0.40 mm or more. The width of the land 2 is set to such a value that the land exfoliation due to the solidification/shrinkage of the lead-free solder 6 and the shrinkage of the circuit board in the thickness direction can be prevented. The circuit board 1 has circuit wires at least on both the surface and the back surface.

摘要： The present invention provides a board ensuring no peel-off of a wall and a land, even if a part is soldered to the board with lead-free solder. The board 10 is comprised of N (N≧3) layer patterns electrically insulated from one another, and is formed with a through-hole 14 into which an electrode 19 of an electronic part 18 is to be inserted. An external land 15 is formed on a surface of each of the first and N-th layer patterns. An electrically conductive layer 17 is formed on an inner wall of the through-hole 14 such that the electrically conductive layer is electrically connected to the external land 15 of each of the first and N-th layer patterns. The electronic part 18 is fixed in the through-hole 14 with lead-free solder 20 filled in the through-hole 14. At least one internal land 16 extending from the electrically conductive layer 17 is formed in the same layer as a M-th layer pattern (2≦M≦(N−1)). The internal land 16 is not electrically connected to the M-th layer pattern.

摘要： A circuit board includes a plurality of through holes (14, 44) into which a plurality of leads (18) of one electronic devices are inserted and soldered. Among these through holes (14, 44), the volume of through hole (14b, 24b, 34b, 44b, 54, 64b) into which the outermost end lead of leads (18) of the electronic device is inserted, is set greater than the volume of through hole (14a, 44a), into which the lead at the position nearest to the center of the electronic device is inserted. Alternatively, the size of through hole (14b, 24b, 34b, 44b, 54, 64b), into which the outermost end lead of leads (18) is inserted, the size being measured in a direction of a straight line that connects a position of the outermost end lead of leads (18) of the electronic device, which is mounted before being soldered, and a center position of the electronic device at the time when the electronic device is mounted, is larger than the size of through hole (14a, 44a), into which the lead of leads (18) which is located at the position nearest to the center of the electronic device is inserted, the size being measured in any direction in a plane. Alternatively, the center position of through hole (74b), into which outermost end lead (18) of the electronic device is inserted, is shifted in a direction away from or approaching the center position of the electronic device at the time when the electronic device is mounted, from the position of outermost end lead (18) of the electronic device, which is mounted before being soldered, in accordance with the relationship between the amount of thermal expansion of the electronic device and that of the circuit board.
