Semiconductor Testing related to Printed Circuit Boards:
High frequency/ density characteristics for applications such as (vertical) probe card, load board…etc. resulted from the increasing specific requirements for impedance control, thickness, flatness and so on.
Please find below some examples to the successful PCB prototypes that we have done:
