Description

用于承载芯片模块的卡片基材及其智能卡 技术领域
本发明涉及智能卡领域，尤其涉及一种用于承载芯片模块的卡片基材、以及具有该卡片基材的智能卡。
 背景技术
智能卡，又称IC卡、智慧卡、微电路卡、微芯片模块卡等，其因体积小便于携带、存储容量大、可靠性高、使用寿命长、保密性强、安全性高等特点而被广泛应用于支付卡、SIM卡、交通卡、信用卡等领域。智能卡与读写器之间的通讯方式既可以是接触式，也可以是非接触式。接触式智能卡在使用时，通过有形的金属电极触点将卡的集成电路与外部接口电路直接接触连接，提供集成电路工作的电源并进行数据交换。非接触式智能卡由于其芯片模块通过锡膏等导电材料与智能卡内部的感应天线电连接，使用时仅需接近读卡设备，即可以通过无线电波与读卡设备进行远距离感应而读取数据。
无论是接触式智能卡还是非接触式智能卡，其均包括卡片基材、以及收容于卡片基材内的芯片模块，且其在制造完成后往往需要通过三滚轮测试仪（即使用三滚轮挤压芯片模块而模拟银行存取款机等读取设备）进行可靠性测试。然而，现有一些类型的芯片模块比较薄而且软，在进行三滚轮测试时，芯片模块容易被损坏而导致无法通过可靠性测试。
 技术问题
鉴于此，本发明旨在提供一种可以解决或至少减轻上述问题的用于承载芯片模块的卡片基材、以及具有该卡片基材的智能卡。

优选地，所述第二凹陷部的轮廓用于对芯模块片进行良好的支撑和保护，使所述芯片模块在进行三滚轮测试时不会吸收太多的振动和挤压。
优选地，所述第二凹陷部的轮廓大致呈橄榄球形。
另一方面，本发明提供一种智能卡，所述智能卡包括所述的卡片基材、以及收容于所述卡片基材的所述凹陷部内的芯片模块。
 有益效果
本发明中的第二凹陷部的轮廓类似两个相对的三角形，当芯片模块装配至本发明提供的卡片基材后，以对芯片模块进行良好的支撑和保护。即使在进行三滚轮测试时，芯片也不会吸收太多的振动和挤压，从而有助于提高芯片的可靠性测试的通过率。

 本发明的实施方式
以下将结合附图以及具体实施方式对本发明进行详细说明，以使得本发明的技术方案及其有益效果更为清晰明了。可以理解，附图仅提供参考与说明用，并非用来对本发明加以限制，附图中显示的尺寸仅仅是为了便于清晰描述，而并不限定比例关系。
参考图1至图3，本发明的智能卡包括矩形的卡片基材10、以及收容于卡片基材10内的芯片模块20。本发明的智能卡制造完成后在进行三滚轮测试时，其中一滚轮30挤压于芯片模块20的表面，另外两滚轮30间隔挤压于卡片基材10的与芯片模块20相对的一表面。测试时，各滚轮30沿着卡片基材10的长度方向往复滚动，以模拟银行取款机等读取设备，从而对芯片模块20进行可靠性测试。换言之，各滚轮30滚动的方向与将智能卡插入取款机或者从取款机取出智能卡的方向一致。值得说明的是，本发明的智能卡既可以采用接触式通讯方式，也可以采用非接触式通讯方式。当采用接触式通讯方式时，芯片模块20的用于与外部接口电路直接接触的金属层形成于所述芯片模块20的外表面并优选与所述卡片基材10的表面齐平。
参考图4至图6，本发明第一实施例的智能卡的卡片基材10具有相对的第一表面11和第二表面12、以及自所述第一表面11朝向所述第二表面12凹陷的用于容纳所述芯片模块20的凹陷部13。所述凹陷部13包括自所述卡片基材10的第一表面11朝向所述卡片基材10的第二表面12凹陷的第一凹陷部14、以及自所述第一凹陷部14的底壁朝向所述卡片基材10的第二表面12进一步凹陷的第二凹陷部15。所述第一凹陷部14用于收容芯片模块20的基板21，所述第二凹陷部15用于收容芯片模块20的芯片22，其中芯片模块20的基板21与芯片22电连接。
本实施例中的智能卡可实现非接触式读取，其卡片基材10上还形成有自所述第一凹陷部14的底壁朝向所述卡片基材10的第二表面12进一步凹陷的两个第三凹陷部16，两个第三凹陷部16分别位于第二凹陷部15的沿智能卡的插入方向的两端。两个所述第三凹陷部16内均收容有导电材料160，例如锡膏，用于分别连接芯片模块20的电源正负极和布置于卡片基材10内的天线（未示出）。
以图7A和7B作为参考，定义智能卡的插入方向为左右方向X，与智能卡的插入方向垂直的方向为上下方向Y。在左右方向X上，本发明的智能卡的卡片基材10的第二凹陷部15的尺寸从中间逐渐向两侧收窄。在上下方向Y上，本发明的智能卡的卡片基材10的第二凹陷部15的尺寸也从中间逐渐向两侧收窄。第二凹陷部15的轮廓的右端点与上端点之间的连线以及第二凹陷部15的轮廓的右端点与下端点之间的连线形成的夹角在R3在50度到80度之间。同样地，第二凹陷部15的轮廓的左端点与上端点之间的连线以及第二凹陷部15的轮廓的左端点与下端点之间的连线形成的夹角也在50度到80度之间。
假定第二凹陷部15的轮廓的上端点与左端点之间的连线以及第二凹陷部15的轮廓的上端点与右端点之间的连线形成的夹角为R4。优选地，所述夹角R4在100度到130度之间。同样地，第二凹陷部15的轮廓的下端点与左端点之间的连线以及第二凹陷部15的轮廓的下端点与右端点之间的连线形成的夹角也在100度到130度之间。
优选地，第二凹陷部15的轮廓的左、右端点之间的距离M3与上、下端点之间的距离M1的比值在1.2至2.5之间。所述第二凹陷部15的轮廓的左、右端点之间的距离M3在2.5mm~7.5mm之间。第二凹陷部15的轮廓的上、下端点之间的距离M1在2.5mm~5mm之间。
本发明的第二凹陷部15的轮廓类似两个相对的三角形，当芯片模块20装配至本实施例中的卡片基材10中后，对芯片进行良好的支撑和保护。即使在进行三滚轮30测试时，芯片也不会吸收太多的振动和挤压，从而有助于提高芯片的可靠性测试的通过率。
具体到图7A和7B所示的实施例，卡片基材10的第一凹陷部14的轮廓大致呈矩形并包括四个首尾相连的第一直线区段140。优选地，第一凹陷部14的轮廓还包括用于连接相邻的两个第一直线区段140的圆弧形的第一连接区段141。
本实施例中，卡片基材10的第二凹陷部15的轮廓大致呈橄榄球形，包括沿左右方向X布置的两个对称且彼此连接的弯曲区段150。所述弯曲区段150包括大致位于中部的第一圆弧形区段152、分别连接于所述第一圆弧形区段152的两端的两第二圆弧形区段153、以及分别连接于所述两第二圆弧形区段153的远离所述第一圆弧形区段152的一端的两第二直线区段154。每一弯曲区段150的一第二直线区段154与另一弯曲区段150的一相应的第二直线区段154连接。在其他实施例中，两个弯曲区段150在左右方向X上也可以不对称。
本实施例中，两个第一圆弧形区段152的中点分别为第二凹陷部15的轮廓的左、右端点。上侧第二直线区段154上的任意一点为第二凹陷部15的轮廓的上端点。下侧第二直线区段154上的任意一点为第二凹陷部15的轮廓的下端点。
优选地，所述第一圆弧形区段152对应的圆心角R1在81度到134度之间。所述第一圆弧形区段152的半径r1在0.4mm到1mm之间。优选地，所述第二圆弧形区段153的圆心角R2在16度到40度之间。所述第二圆弧形区段153的半径r2在3mm到7mm之间。
由此可见，本实施例中的第二凹陷部15的轮廓包括六个圆弧形区段（两个第一圆弧形区段152和四个第二圆弧形区段153）和两个直线段（每一直线段包括两个第二直线区段154）。值得注意地是，本实施例中的圆弧形区段和直线区段的数量和排布仅作为示例示出，在其他实施例中，也可以采用其他数量和排布的圆弧形区段和直线区段。例如，在其他实施例中，第二凹陷部的轮廓可以仅由多段圆弧形区段连接而成，或者上述第一圆弧形区段152和第二圆弧形区段153可分别由多段圆弧构成。又或者，在一些实施例中，第二凹陷部的轮廓可以由多个圆弧形区段和多个直线区段构成，其中多个圆弧形区段可以依次连接，多个直线区段可以依次连接再和前述的依次连接的多个圆弧形区段的两端连接，或者，多个圆弧形区段和多个直线区段可以周期性间隔地排布和连接，又或者，多个圆弧形区段和多个直线区段可以无规律地随意连接和排布，只要最终形成的第二凹陷部可以利用其特定的形状对芯片模块起到良好的支撑和保护即可。
参考图8，本发明第二实施例的智能卡与第一实施例的智能卡类似，相同之处在此不再赘述。第二实施例的智能卡与第一实施例的智能卡的主要区别在于，本实施例中的智能卡为接触式智能卡，第二实施例中的凹陷部213不再包括前述第三凹陷部16。
参考图9，本发明第三实施例的智能卡与第一实施例的智能卡类似，相同之处在此不再赘述。第三实施例的智能卡与第一实施例的智能卡的主要区别在于第二凹陷部的轮廓有些许不同。
具体地，本实施例中的第二凹陷部315的轮廓的弯曲区段350不再包括所述第二直线区段154，而仅包括大致位于中部的第一圆弧形区段352、以及分别连接于所述第一圆弧形区段352的两端的两第二圆弧形区段353。每一弯曲区段350的一第二圆弧形区段353与另一弯曲区段350的相应的一第二圆弧形区段353直接相连。优选地，两个弯曲区段350在左右方向上对称。
优选地，所述第一圆弧形区段352对应的圆心角R6在81度到134度之间。所述第一圆弧形区段352对应的半径r3在0.4mm到1mm之间。优选地，所述第二圆弧形区段353对应的圆心角R7在16度到40度之间。所述第二圆弧形区段353对应的半径r4在3mm到7mm之间。相邻的两个第二圆弧形区段353可以在同一个圆周上，也可以在不同的圆周上。当相邻的两个第二圆弧形区段353在同一个圆周上时，两个第二圆弧形区段353也可以合并视为一段圆弧。
参考图10，本发明第四实施例的智能卡与第一实施例的智能卡类似，相同之处在此不再赘述。第四实施例的智能卡与第一实施例的智能卡的主要区别在于第二凹陷部的轮廓不同。
具体地，本实施例中的第二凹陷部415的弯曲区段450包括两个第三直线区段451。两个弯曲区段450共同围合形成一大致呈菱形的轮廓。本实施例中的第二凹陷部415的轮廓还包括用于连接相邻的两个第三直线区段451的圆弧形的第二连接区段452。
优选地，每一弯曲区段450的两第三直线区段451之间形成第一夹角R8，所述第一夹角R8在50度到80度之间。两个弯曲区段450的相邻的两第三直线区段451之间形成第二夹角R9，所述第二夹角R9在100度到130度之间。可以理解地，在其他实施例中，第二凹陷部415的轮廓也可以不呈菱形，而呈两个不对称三角形构成的四边形。例如，两个弯曲区段450可以具有不同的第一夹角R8。
以上所述仅为本发明较佳的具体实施方式，本发明的保护范围不限于以上列举的实施例，任何熟悉本技术领域的技术人员在本发明披露的技术范围内，可显而易见地得到的技术方案的简单变化或等效替换均落入本发明的保护范围内。
