5. Purpose and Significance of RF stiching?

Purpose and Significance of RF stiching?


  • Hi all,

    I've been recently trying my hands in high speed and RF PCB designs. I have recently learnt that we need to stitch the high speed traces all along their way. I have read many sources saying different reasons. But, I haven't landed on any solid answer. Please do explain me this concept if any one knows this. Thanks in advance..!!

  • Via stitching is a technique used in PCB design to reduce the EMI , to keep the short return loops and maintain the low impendence through tracks. especially on the larger copper areas

    @salmanfaris best if you could point me to an example that works as described: getting different values depending on hoe close the finger is without really touching. nothing i tried did work yet

    @salmanfaris I haven't found a good sensor module for this at all. I used a thing which was calles touch sensor and it returns only 1/0. Tried to use touchRead() but it is not sensitive apparently, only 40 and 1 more or less.

    #define touch_pin_numer 33

    const int VALUE_THRESHOLD = 30;
    int TOUCH_SENSOR_VALUE;
    void setup()
    {
    Serial.begin(115200);
    delay(1000);

    }
    void loop(){
    TOUCH_SENSOR_VALUE = touchRead(touch_pin_numer);
    Serial.println(TOUCH_SENSOR_VALUE);
    if(TOUCH_SENSOR_VALUE < VALUE_THRESHOLD)
    {
    Serial.println ("Touch ON");
    }
    else{
    Serial.println ("Touch OFF");
    }
    }

    should show something between 40 (current max) and 1 (current min) the closer the finger gets but it shows 40/41/39 and 1 - nothing inbetween. got this code from the web

  • @FlorianB Can you share the code, output window/error and details of the sensor module?

    Hi! I am trying to add an capacitive sensor to the ESP32, that will work through glass with 3mm thickness and an distance of 8 to 2 cm. I have bought sensors which only work on touch, i have looked into the touchRead() function but cant get a steady value increase/decrease with distance and only a real touch gets me enough difference to count it as a "touch". I have checked Arduino examples with foil where a resistor can set the sensitivity but nothing worked on my ESP32. i have spent hours looking for an example, can somebody point me to one please?
