Is it true that PCB antennas can be tuned by only changing their length?
My PCB antennas fail to achieve resonance, though I have changed their length. Our new product project is obstructed due to this problem now. Are there any good solution else?

Just interested in PCB design. I am wondering whether PCB traces start to act as antennas at some frequency. Anybody knows?
I am dealing with a project about a PCB with NFC antenna. We are designing PCB now. Do anyone know about the size of an NFC antenna if we want it operate in 10 centimeters?
Recently, I have learnt about kernel and find a question that who controls the process control block(PCB)?The kernel or the process itself? Does it differ in different platform (windows/Linux)? So far, I know PCB is controlled in hardware, but I can’t get to the right answer.
To my understanding, each process in the operating system contains its own separate Process Control Block. Can someone explain this to me. Does each process have its own PCB or is there just one PCB that contains all the information for all the processes?
We are glad to find you have ISO and BSCI certification. Could you please tell what is the warranty of your PCBA product? I mean, on average.
We plan to visit factory next week. Could we know more about how many basic PCB testings in EMS field?
How does a conventional board house deal with the issue of reflow during PCB component assembly with BGA’s on both sides of the board?
Are two different solders used (like regular lead free SAC305 and a low temp?)
Last week we visited a PCBA factory. We were looking at reflow ovens. A lot of them have a metal conveyor belt the boards sit on. On a double sided board, when you put the board on the metal belt, won’t the metal belt knock components off as they are only held on by paste?
