Hatisitsoeng oa Potoloho Board Selelekela

A Boto ea potoloho e mechanically supports and electrically connects electrical or electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.PCBs can be single-sided (one copper layer), double-sided (two copper layers on both sides of one substrate layer), or multi-layer (outer and inner layers of copper, alternating with layers of substrate). Multi-layer PCBs allow for much higher component density, because circuit traces on the inner layers would otherwise take up surface space between components. The rise in popularity of multilayer PCBs with more than two, and especially with more than four, copper planes was concurrent with the adoption of surface mount technology.

Liboto tsa potoloho tse mahlakore a mabeli li rarahane ho feta PCB e nang le lehlakore le le leng. Liboto tsena li na le karolo e le 'ngoe feela ea substrate ea motheo. Leha ho le joalo, li na le lihlopha tsa conductive ka lehlakoreng le leng. Ba sebelisa koporo e le thepa conductive. Ha re ikakhele ka setotsoana ka har'a PCB e mahlakoreng a mabeli ho ithuta haholoanyane!
