摘要: A method of manufacturing a printed wiring board with solder bumps includes forming a solder-resist layer having small and large apertures exposing a respective conductive pad of the printed wiring board, loading a solder ball in each of the small and large apertures using a mask with aperture areas corresponding to the apertures of the solder-resist layer, forming a first bump having a first height, from the solder ball in the small aperture, and a second bump having a second height, from the solder ball in the large aperture, the first height being greater than the second height, and pressing a top of the first bump such that the first height becomes substantially the same as the second height. A multilayer printed wiring board includes a solder-resist layer with apertures of differing sizes and solder bumps having substantially equal volumes but a difference in height no greater than 10 μm.

摘要: A solder ball loading method capable of securely loading solder balls on connection pads includes applying flux on each connection pad group of a printed wiring board flux is not applied to a contact portion between a spacer and the printed wiring board to keep the flux from attaching to the spacer. Because the flux is not attached to the spacer, when the mask is detached from the printed wiring board, the printed wiring board need not be inverted, and damage to the solder resist layer 70 is minimized. Further, the heights of the solder balls and the upper surface of the mask are made equal by using the spacer, making it possible to securely load the solder balls on the electrode pads, one solder ball for each connection pad, and to reduce a probability that solder balls are not loaded or that a plurality of the solder balls are loaded onto a single connection pad.

摘要: A solder ball is loaded on a bump having a small height (FIG. 5(B)) and the height of the bump is intensified by melting the solder ball by heating with laser (FIG. 5(C)). Thus, the heights of the bumps are adjusted within a requested allowable range. Because the bump is not removed by heating when the height of the low bump is intensified, the printed wiring board is not subjected to local heat history thereby intensifying reliability of the bump of a printed wiring board.

摘要: A printed wiring board comprises a wiring substrate provided with at least one conductor circuit, a solder resist layer formed on the surface of the wiring substrate, covering the at least one conductor circuit, conductor pads formed on a part of the at least one conductor circuit exposed from respective openings provided in the solder resist layer for mounting electronic parts, and solder bumps formed on the respective conductor pads. Connection reliability and insulation reliability are easily improved by making the ratio (H/D) of a height H from solder resist layer surface the solder bump to an opening diameter of the opening about 0.55 to about 1.0 even in narrow pitch structure under the pitch of the opening provided in the solder resist layer of about 200 μm or less.
