Akatswiri omwe akhala akuchita PCB masanjidwe kwa zaka afotokozera mwachidule zina mwazikuluzikulu zodetsa nkhawa, zomwe mphamvu yamagetsi ndi malo oyenera kuziganizira. Kotero, momwe mungapangire dera lamagetsi pakapangidwe ka board ya PCB?

Choyamba, bolodi lamagetsi ndilofunika kwambiri kuti mupirire gawo lamagetsi, pakakonzedwe kake liyenera kudziwa gawo lamagawo azizungulira, mdera lamagetsi limagawika kwambiri dera la DI / DT ndi dera la DV / DT, yendani pomwe Kukhazikitsidwa kwa mizere iwiri sikofanana.
