摘要： An improved surface mounting method applied in a semiconductor package process is provided, wherein the method comprises the following steps: First a substrate having at least one pad set on one surface of the substrate is provided. Then a mask having at least one opening associated with one of the at least one pad is set on the substrate, wherein each opening is separated into a plurality of sub-openings by a segregator to expose the pad. Subsequently, a printing process is conducted to form a conductive layer on each pad. After removing the mask, a passive device is set on the conductive layer over the pad, and a heating treatment is conducted to fix the passive device on the pad.

摘要： The present invention relates to a substrate structure having non-solder mask design (N-SMD) ball pads. The substrate structure comprises a substrate and a solder mask. The substrate has a first surface, a trace layer and at least one ball pad. The ball pad and the trace layer are disposed on the first surface. The trace layer has a plurality of traces, and at least one trace electrically connects to the ball pad. The solder mask has at least one opening corresponding the ball pad. The size of the opening is larger than that of the ball pad. The solder mask covers the trace connecting to the ball pad. By utilizing the substrate structure of the invention, the problem of non-alignment of the solder ball can be solved, and the hole in the solder ball can be prevented when the substrate structure is welded with a PCB so that the reliability of solder ball welding can be improved.
摘要翻译：本发明涉及具有非阻焊掩模设计（N-SMD）球垫的衬底结构。衬底结构包括衬底和焊接掩模。基板具有第一表面，迹线层和至少一个球垫。球垫和轨迹层设置在第一表面上。迹线层具有多个迹线，并且至少一个轨迹电连接到球垫。焊接掩模具有至少一个对应于球垫的开口。开口的尺寸大于球垫的尺寸。焊接掩模覆盖连接到球垫的迹线。通过利用本发明的衬底结构，可以解决焊球不对准的问题，并且当衬底结构用PCB焊接时可以防止焊球中的孔，从而焊球焊接的可靠性可以改进。
