- Do you recommend any App/ tool for impedance calculation that has accurate results? I used the Polar Si8000 before but I didn't have a budget to purchase the license
- What kind of substrate do you recommend?
Thanks

Due to the via in-pad process, the board house suggests using...
I need some help to decide about the way I'm designing the circuit to achieve the best antenna performance while meeting the 50ohms impedance for the transmission line, in the first example below, I made the line width 10.7 mil and the gap equal to 5 mil, on the second example, the line width...
I already sent them an email to ensure the pad size is okay, but I haven't gotten a response yet.
I also validated the dog-bone design strategy, it seems okay with 5 mil clearance, I can insert a 15 mil via in between the pads with 8 mil drill hole, thoughts?
Sorry, I meant the spacing between the pad edges is 0.35 mm, the pitch is 0.70 mm
I was thinking about VIPPO and it's doable on my PCB but I need to confirm with the board house, have you tried that with the 0.35 mm pad size? if so, can you provide some more information like the size of the...
I need help to decide between designing a PCB with or without blind via's.
Currently, I'm working on the 6 layers PCB, thickness 0.062", the main component that required blind via is LGA173 package with 13.7 mil pads pitch.
I have the option to proceed without the need for blind via's (by...
Looking to have an advice to select the material that is equal to the human body dielectric , I tried one of the goop phantom that we have from a long time ago (not make sure what is the material) but there is a huge difference when I tried to tune the antenna with phantom vs. human body.
