Cần hỗ trợOneplus 8 switch test connectors

Does anyone know what type of connector these extra small switch test connectors are?
They are also used in Oppo devices. They are used for 5G and also WiFi/BT antennas and are much smaller than the other ones seen on the PCB
Much appreciated

 

Never seen it, but why don't you use copper wires to connect them?
Why do you need this connector?

 

Hi,
I do lots of RF testing on new flagship devices, using the correct connector isolates RF line from the antenna without risk of damage to the board. Now I am seeing the same connectors on Oppo and Oneplus devices I was hoping to be able to source these, I cannot find the type. I believe these will become more common when 5G is in more devices

 

i thinke it it is writing on back cover

 

Nope, there's nothing written on them
