Abstract

具有装在基板(3)上并电接触的部件系统(1,2)的OFW部件,其中在部件侧面上提供面向离开部件系统(1,2)和基板(3)连接区方向的保护层(8)以及保护层(8)对部件系统(1,2)形成防止对基板(3)受环境影响的密封层。

Description

电子部件，尤其是利用声表面波工作 的电子部件-OFW部件
根据权利要求1的描述，本发明涉及电子部件，尤其是涉及用声表面波工作的部件-OFW部件。
大家知道，电子部件通过保护层防止环境影响如化学物质或许湿度的侵蚀。因而例如US-PS3438873描述通过氧化硅、氮化硅和混合硅化物如或许为硅酸铝保护半导体部件。这时保护层直接涂敷到半导体部件的系统上。这里关于部件系统理解为包含部件的有源电子元件的基板。换言之表示在部件系统情况下涉及除了包含部件的外壳之外的部件。
在确定的电子部件情况下上述类型的保护层涂敷到部件系统本身上可能是不合适的，甚至对部件功能有害。例如在用声表面波工作的部件情况下就是这种情况，因为在这类部件的部件系统上涂敷保护层能影响声表面波的传播。对此的另一例是机械应力的传感器，因为由传感器系统内的保护层引起机械的过大应力能影响对于待测机械应力的检测。
基于本发明的任务是：给出一种办法能够防止电子部件受环境影响，而且能够不因涂敷在部件系统上的保护层产生损害。
本任务在本文一开始类型的电子部件情况下根据本发明由权利要求1特征部分的标志解决。
本发明的改进为从属权利要求的对象。
本发明依靠附图的图所描绘的实施例详细说明如下。这里图1到图3图示给出了由本发明构成的电子部件的各种实施例。
在图1电子部件实施例，一部件系统电接触装配在基板3上。部件系统通过衬底上和包围未图示导电结构的绝缘框架2简略描述。在此导电结构情况下，对于OFW部件它可以涉及到例如叉指式换能器、谐振器或反射器。
在本发明的范围内所谓“基板”理解为在合成物基、玻璃基或陶瓷基上的印刷电路衬底。在基板3上提供印制导线4，该印制导线经缓冲件5与部件系统的衬底1上的(未图示的)导电结构相接触。在这种电接触中涉及本身公知的所谓倒装晶片式安装。
在包围衬底1上导电结构的框架2和印制导线4之间提供例如由环氧树脂或玻璃构成的绝缘层6。最后在部件系统1、2和基板3之间的联接区提供一镶框7，在该镶框可涉及例如粘着剂、热塑合成树脂或塑胶。因此特别提供该镶框以便吸收由部件系统和基板的不同热膨胀引起以及能够通过缓冲件5机械上损害在衬底1上导电结构和基板3的印制导线之间电接触的剪力。
根据本发明在遍及结构部件系统1、2和基板3之间连接区的部件端上，提供一保护层8用于对部件系统形成防止对基板环境影响的密封的封闭层。正如在以下还要详细说明的那样，该保护层可以不同方式构成。
在图2的OFW部件的实施例中OFW的部件系统通过压电衬底10并在该预定的导电结构11和为导电结构的引线面12-焊接点-上形成。在导电结构11的情况下例如又涉及叉指式换能器、谐振器或反射器。导电结构11和焊接点12按照图1的实施例为绝缘框架21所包围。而图2的OFW部件系统10、11、12的描绘完成是图解性质。OFW部件用的这种部件系统的完整结构本身是大家熟悉的，因此在这里不详细说明。
此外，提供一基板13，在其转向部件系统10、11、12的侧面上提供在其上具有缓冲件15的印制导线14，经缓冲件15实现部件上在焊接点12的接触。基板13的构成不限于双层性。多于两层也是可以应用的。
由部件通过下述方式引出电接通，即，印制导线14围绕基板13建立，正如在图2左侧所示，或者通过基板经引线16-1,16-2,16-3在基板13的外侧与印制导线17相连。电引线16-1,16-2,16-3在垂直方向偏心安排用于阻止影响部件功能的化学物质进入，即：通过引线的偏心构成保证从基板13的外侧来的气密性。当印制导线14围绕基板13建立并经缓冲件15与焊接点12相连，则在印制导线14和下述保护层19之间必须一绝缘层20。
部件系统10、11、12通过塑料涂层18覆盖在基板13上。该覆盖层18通过热塑合成树脂、塑胶或热塑形成。
根据本发明在覆盖层上面向离开部件系统10、11、12和基板13之间的连接区方向提供根据本发明的保护层19，该保护层形成防止对基板13环境影响的密封层。
正如以上说明，图1的保护层8和图2的保护层19可以不同方式构成。根据实施例它可以是包含金属的层或完全金属层。此外，它也可以通过多个分层形成(在图1和2内并未特别表示)，其中至少有一层是金属层。此外分层之一可以是玻璃层，此时涉及分层系列的下分层。例如，铜、镍或金可考虑作为金属区。金属层可以通过蒸发、真空金属喷涂、电镀或叠层胶合涂敷。在必要时在金属层上提供未特别说明的抗腐蚀层。此外，在金属层下也可以提供未特别描绘的粘附层。
正如依靠图2的实施例描绘的那样，保护层19，即：尤其是其金属部分是电接触的，以致保护层19不仅是对环境影响起保护的层，而且同时也形成对部件系统10、11、12的高频屏蔽。但是为此目的，保护层19与基板13上的印制导线14相连，正如在图2通过焊接22所描绘的那样。
在图1和图2的相同部分提供同一参考符号的图3给出一实施例，其中部件系统是导线连接的。这时衬底1借助一合适的连接，例如粘接30固定在基板3上。在转向固定区的一侧，经接触线31引线连接到印制导线4上。
在本实施例，按照图2的实施例塑料涂层18提供一本发明的保护层19。
