Elke printplaat kan met afgeronde randen worden vervaardigd, afgeronde hoeken, enzovoort. Met moderne fabricagemethoden, het is denkbaar dat de hele printplaat tot een ronde bal kan worden gemaakt.
The mission of PCB is to support the components mounted on it, and to supply the electrical connections between them. As long as it carries out these two functions the actual, shape doesn’t matter.

#PCB-ontwerp
After making efforts in a period, I finally finish my PCB design. Next step is releasing them to factory for production. To be honest, I don’t want any mistake on my file which may interrupt further prodution process. So what points should I pay attention when I double-check my design?
I’m making a 4 layer PCB prototype that uses a bluetooth mcu connected to a 2.4GHz chip antenna. I’m thinking about what to do with the feedline, whether it should be buried on one of the middle layers, or left on the top layer. To get a 50 ohm line, should I choose top layer with 13-mil width or buried miccrostrip with 7-mild width?
Although the adsorption of moisture by FR4 is quite low, what is the best way to minimize it or eliminate it completely?
