As you know for EMI dome array, there is an EMI layer on the top of metal dome array. So what’s the function of EMI? OK, follow me:
EMI dome array is that there is a sliver paste is printed on the top layer as ESD (electrostatic Discharge Control). It can help to reduce the electrostatic which maybe hamful to the other parts inside of the mobile phone, and to protect the product.There are also two “contact eyes”(we named) to let me electrostatic run way. The contact resistance can reduce to less than three ohm.
This item are mostly used in our china marketing, and used in the cellphone products. Do you need the dome array made into EMI? Please contact us for your required.
