Any PCB can be manufactured with rounded edges, rounded corners, etc. With modern fabrication methods, it is conceivable that the entire PCB could be made into a round ball.
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.

Muitas vezes, nosso fabricante de PCBA nos liga sobre um problema no arquivo de projeto. Às vezes pensamos que é demorado discutir esta questão. Só quero saber por que eles sempre fazem isso.
eu pedi placa, mas não consigo programar na memória QSPI.?
I am prototyping a PCB, using Chip Quik’s “SMDSWLF.031, a Sn96.5/ Ag3.0/ Cu0.5 solder with 2.2% no-clean flux. I find that the black spots appears frequently in larger pads on my board. I wonder if it is because I left the soldering iron more time heating the solder and that burnt the flux. What is that black residue? Is that a sign of a bad joint or maybe bad soldering technique?
