Hemeixin Electronics Co.,Ltd.
Radio-frequency PCB and Microwave PCB can be found in countless wireless products from handheld devices for medical and industrial applications to advanced communications systems for base stations, radar and global positioning. The success of these high-speed products begins at the product design stage when the PCB laminate materials are selected.
HemeixinPCB has created the option of checking the required impedance on the customer's Circuit Board, so as to modify the circuit board, or the tracks and the layer structure if necessary. The impedance is largely determined by the track geometry, the structure of the layers and the dielectric constant (Er) of the materials used.
After making the circuit board, the impedances are checked and recorded. The results of the measurements are available on request at any time.
