Is it better to have round corners on a PCB?

When I visit the PCB showroom in factory, I find that there are some pcs with round corners. Is it better to have round corners on a PCB?
  • Consider whether it is necessary to make round corners to fit in your product shells.
  • If you want to pay for them. You can have any shape you like, at a similar price.

Generally speaking, PCBs are made by a big sheet of fiberglass, followed by line scoring. When they come to assembly line, they will be broken up along the scored lines which are generally straight lines.

If you want rounded corners, or some other shape, the PCBs have to go to an extra process on another machine. Thus, it required extra cost.

Why are RF PCBs hard to design?

I am a project procurement. Recently, Our project is to develop a television. Of all the materials supply, PCB was the slowest one. And even our engineer took part in the discussion with PCB supplier to push them. Is it really hard to make a RF PCB?

How can I fix the PCB to the mechanical structure?

I designed a PCB with an imaging sensor that is mechanically coupled to a lens assembly using four 2-56 screws. I’m noticing that even though the screws are holding the board tightly against the mechanical structure if I flick or lightly knock the the assembly the image “moves”.  I’m hoping to get a few suggestions for ways to fix the PCB to the mechanical structure. Any suggestions for adhesives or the like? Something else?
