曲线形状滑块设计是否所有的滑块都必须等尺寸?

你好,
我们的目的是将CasSooLoad片段弯曲形状(如附录中所示),并有以下查询。
1 &是否有任何指南文件可用于沿曲线路径放置滑块段?
2、是否所有的滑块都必须等尺寸?
3对滑块段的接地网宽度是否有要求?由于我们打算把滑块靠近板边缘,并有非常小的空间为地面网格一侧。
4滑块轨迹与10密耳间隙平行(在它们之间没有接地网)?
5和gt;在图像的一个侧面放置CasSook IC可以吗?
谢谢,
毗沙尔

  Hello,

We are intended to place capsense slider segments in curved shape  ( as shown in attached file ) and have below queries.

1> Is there any guideline document available to place slider segment along curved path ?
2> Is it must to have all slider segments in equal dimension ?
3> Is there any requirement on width of the ground mesh around slider segment ? As we intend to place slider close to board edge, and have very small room for ground mesh on one side.
4> Can slider trace run parallel with 10 mil clearance in between ( No ground mesh in between them) ?
5> is it Ok to place capsense IC on one side of slider , as shown in image ?

Thanks,
Vishal

嗨,Vishal,
请在下面找到答案:
“1 &是否有任何指南文件可将滑块段沿曲线路径放置?”
-没有指定曲线滑块的特殊文件。我们的基本建议是保持所有的传感元件在手指位置和实际输出之间的线性一致。所以你可以只使用线性滑块的建议。
“2,是否所有的滑块都必须在同一维上?”
——是的。否则,输出计数将不与手指的位置成线性关系。
“3”是否对滑块段周围的接地网宽度有任何要求?由于我们打算把滑块靠近板边缘,并有非常小的空间为地面网格一侧。
-GT;周围网格和CAPSENSE传感器之间的气隙应等于覆盖层的厚度。孵化模式的尺寸为7密耳宽度和45密耳间距在顶层,7密耳宽度和70密耳间隔在底层。
“4”与“滑块轨迹平行于10密耳间隙之间(在它们之间没有接地网)吗?”
-gt;推荐的CAPSONE跟踪痕迹为0.25毫米。转换为密尔,为20密耳。
“5”&是否可以将SCAPENSE IC放在滑块的一侧,如图像所示?
-Gt;不建议将IC完全放置在CopSnkes传感器或其他层的轨迹下。除了这个区域,你可以把它放在任何地方。
感谢和问候

  Hi Vishal,
 
Please find the answers below:
 
>>"1> Is there any guideline document available to place slider segment along curved path ?"
 
--> There is no special document for specifying the curved slider. Our basic recommendation is to keep all the sensing elements identical for linearity between finger position and the actual output. So you can go with the recommendations of linear slider only.
 
>>"2> Is it must to have all slider segments in equal dimension ?"
 
--> Yes. Otherwise the output count will not be in linear with the position of the finger.
 
>>"3> Is there any requirement on width of the ground mesh around slider segment ? As we intend to place slider close to board edge, and have very small room for ground mesh on one side."
 
--> The air gap between the surrounding mesh and the CapSense sensors should be equal to the thickness of the overlay. And the dimensions of the hatch pattern is 7 mil width and 45 mil spacing in top layer and 7 mil width and 70 mil spacing in the bottom layer.
 
>>"4> Can slider trace run parallel with 10 mil clearance in between ( No ground mesh in between them) ?"
 
--> The recommended CapSense trace to trace clearance is 0.25 mm. Converting to mil it is 20 mil.
 
>>"5> is it Ok to place capsense IC on one side of slider , as shown in image ?"
 
--> It is not recommended to place the IC exactly under the CapSense sensors or traces in the other layer. Other than this area you can place it anywhere.
 
Thanks and Regards
Ganesh
