你好,
我必须设计一个使用卡普森按钮传感器的PCB。因为这是我第一次用CyPress产品设计一个板,我对布局有一些问题: -如果按钮传感器在顶层,我能有一些东西,比如它下面的CY8CMBR3108,或者它需要一些间隙吗? -我想给一些LED提供反馈,是否可以在传感器的中间放置2(焊接在底部,面对一个孔)?如果我想在同一技术上添加另一个LED,那么从传感器的侧面我能走的最小距离是多少? -如果我很好地理解了这个文件HTTP://wwwyCysP.com/FIL/41076/下载页面81,一个孵化的地面必须出现在第3层,并且在底层的空白空间,但是顶层怎么办?我需要在顶层的另一个孵化地,在传感器周围有间隙吗? -我能用第三层(我想是地面层)来根植非卡彭斯的痕迹吗? 对不起,如果我的问题看似微不足道,但阅读文档后,我不是100%肯定,并希望得到一些建议。 提前感谢 以上来自于百度翻译 以下为原文 Hello, I have to design a PCB using a capsens button sensor. As it is my first time design a board with cypress product, I have some questions about the layout: -If the button sensor is on the top layer, can I have something, like the CY8CMBR3108 beneath it, or does it needs some clearance? -I want to ad some LEDs for feedback, is it possible to put 2 in the middle of the sensor ( soldered on the bottom, facing a hole)? If I want to add other LED on th side, with the same technic, what is the minimal distance from the side of the sensor I can go? -If I understand well this document http://www.cypress.com/file/41076/download page 81, a hatched ground must be present on layer 3, and on empty space of the bottom layer, but what about the top layer? Do I need an other hatched ground on the top layer with clearance around the sensor? -Can I use the 3rd layer ( aka the ground layer I think) for rooting the non-capsense traces ? Sorry if my questions seems trivial, but after reading the documentation I am not 100% sure and wanted some advice Thanks in advance |

-如果按钮传感器在顶层,我能有一些东西,比如它下面的CY8CMBR3108,或者它需要一些间隙吗?
1。对于不同的层,不需要间隙,但建议使用。此外,建议确保传感器跟踪和通信跟踪(例如I2C跟踪)是垂直的,如果它们在不同的层上。 -我想给一些LED提供反馈,是否可以在传感器的中间放置2(焊接在底部,面对一个孔)?如果我想在同一技术上添加另一个LED,那么从传感器的侧面我能走的最小距离是多少? 2。一般情况下,推荐使用2mm。 -如果我很好地理解了这个文件HTTP://wwwyCysP.com/FIL/41076/下载页面81,一个孵化的地面必须出现在第3层,并且在底层的空白空间,但是顶层怎么办?我需要在顶层的另一个孵化地,在传感器周围有间隙吗? 三。对。顶部有舱口,有净空。 -我能用第三层(我想是地面层)来根植非卡彭斯的痕迹吗? 4。对。你可以。 希望能对你有所帮助! 谢谢, 赖安 以上来自于百度翻译 以下为原文 -If the button sensor is on the top layer, can I have something, like the CY8CMBR3108 beneath it, or does it needs some clearance? 1. For different layer, clearance is not required but is recommended. In addition, It is recommended to make sure sensor trace and communication trace(e.g. I2C trace) are vertical if they are on different layers. -I want to ad some LEDs for feedback, is it possible to put 2 in the middle of the sensor ( soldered on the bottom, facing a hole)? If I want to add other LED on th side, with the same technic, what is the minimal distance from the side of the sensor I can go? 2. Generally, >2mm is recommended. -If I understand well this document http://www.cypress.com/file/41076/download page 81, a hatched ground must be present on layer 3, and on empty space of the bottom layer, but what about the top layer? Do I need an other hatched ground on the top layer with clearance around the sensor? 3. Yes. Hatch ground is recommended on the top layer with clearance. -Can I use the 3rd layer ( aka the ground layer I think) for rooting the non-capsense traces ? 4. Yes. You can. Hope it can help you! Thanks, Ryan |
