    • A circuit board for carrying a chip is provided. The circuit board includes a substrate, a wiring layer and a solder mask. The wiring layer including a cutting line pattern defining a cutting region is disposed on the substrate. The solder mask including a chip region, a first opening and a second opening is disposed on the substrate and the wiring layer. The chip region is disposed inside the cutting region. The chip is suitable to be disposed in the chip region, wherein the chip overlaps the chip region. The first opening and the second opening are respectively disposed outside two adjacent lateral sides of the chip region for exposing a part of the cutting line pattern. The exposed part of the cutting line pattern is used for measuring the position of the chip relative to the substrate.
    • 提供用于承载芯片的电路板。 电路板包括基板,布线层和焊接掩模。 包括限定切割区域的切割线图案的布线层设置在基板上。 包括芯片区域,第一开口和第二开口的焊接掩模设置在基板和布线层上。 芯片区域设置在切割区域内。 该芯片适于放置在芯片区域中,其中芯片与芯片区域重叠。 第一开口和第二开口分别设置在芯片区域的两个相邻侧面的外侧,用于暴露切割线图案的一部分。 切割线图案的露出部分用于测量芯片相对于基板的位置。
