薄膜开关引出线

引出线为一个或多个柔性线路回路的引出部分，用于连接连接器。 此线路可承载多重回路，它的宽度和倾斜度根据需要而定。我厂在倾斜度上的要求处于领先地位。

常有的误区：

引出线是薄膜内一层或多层线路回路引出的一个独立的和完整的线路，改变引出线的长度对于薄膜开关的性能有一定的影响。可以通过增加引出线的宽度而达到增加引出线长度的性能。

设计考虑因素：

对于每一个项目，我 企业会根据以下因素设计引出线：

   (1)电路结构

   (2)顾客所使用的联接器。

   (3)屏蔽层和联接器的要求。

   (4)保证与其它元件完好联接的机械结构设计。

引出线的典型截面图：

    1、 导电银层

    2、 热稳定聚脂

    3 、绝缘保护层

    4、 碳保护层

  注意：

   (1)引出线不能随意被折叠，或是弯曲半径超过2.5mm 。

   (2)如果要求引出线折弯，我 企业会提供可靠的压力、高温定型以满足客户的要求。

   (3)引出线不必被精确地切割成直线，它们可以被修成各种形状以满足不同装配的要求。

   (4)因为引出线是线路层的外延部分，它们不能离开开关触点的下方。

   (5)线路绝缘选项：

     ①碳保护层用于防止银氧化，并保证线路与插针良好联接。

     ②用绝缘油涂印在引出线上的成本较低。

     ③为保证静电和防止磨损， 我企业会提供一层聚脂层用于密封传导线路。

brief introduction

The lead out wire is a lead out part of one or more flexible line loops. The circuit can carry multiple circuits, and the width and the inclination of the circuit can be determined according to the requirement. I plant in the requirements of the tilt in a leading position.

Common mistakes

The lead wire is an independent and complete circuit which leads to one or more lines in the thin film, and the length of the lead wire is changed to have a certain effect on the performance of the film switch. The performance of the lead wire length can be increased by increasing the width of the lead wire.

Design considerations

For each project, my company will be designed according to the following factors:

(1) circuit structure

(2) coupling is used by the customer.

(3) shielding layer and the coupler.

(4) the design of mechanical structure to ensure the good connection with other components.

Typical section of lead outlet

1 conductive silver layer

2 heat stabilized polyester

3 insulation protection layer

4 carbon protective layer

be careful：

(1) lead outlet can not be arbitrarily folded, or bending radius of more than 2.5mm.

(2) if the line is bent, the company will provide reliable pressure and high temperature to meet the requirements of the customers.

(3) lead wire will not be accurately cut into a straight line, they can be built in various shapes to meet the different requirements of assembly.

(4) because the lead out line is the extension of the line layer, they can not leave the lower part of the switch contact.

(5) line insulation options:

The carbon protective layer to prevent the oxidation of silver, and ensure good connection line and pin.

The cost of using insulating oil on the extraction line is low.

In order to ensure the electrostatic and prevent wear, I companies will provide a layer of polyester layer for sealing the transmission line.
