Simbisa iyo PCB maitiro dhizaini yezvigadzirwa, tsanangura zvinoenderana paramita zvePCB maitiro dhizaini, ita Iyo pcb dhizaini inosangana nezvinodiwa zvekugadzirwa, testability, chengetedzo, EMC, EMI uye mamwe maratidziro ehunyanzvi, uye kuvaka zvakanakira maitiro, tekinoroji, mhando uye mutengo wezvigadzirwa. mukuita kwechigadzirwa dhizaini.

Kuongororwa kwematanho ane hukama ePCB maitiro dhizaini

2. Chikero chekushandisa

Tsanangudzo iyi inoshanda kune pcb process dhizaini yezvose zvigadzirwa zvemagetsi, uye zvinoshanda asi zvisingaganhurwe nePCB dhizaini, pcb bhodhi yekukanda maitiro ekuongorora, imwechete bhodhi maitiro ekuongorora uye zvimwe zviitiko. Kana paine kupokana pakati pematanho akakodzera nezviri mune zvakatarwa pamberi peKodhi iyi nezvisungo zveiyi Code, kodhi iyi ichakunda.

3. Tsanangura

Kuburikidza negomba (VIA): Gomba rine simbi rinoshandiswa mukati mekubatana, asi kwete yekuisa yezvinhu zvinotungamira kana zvimwe zvekusimbisa.

Bofu kuburikidza: A kuburikidza-gomba rinotambanuka kubva kubhodhi rakadhindwa kune imwechete nzvimbo.

Kuvigwa kuburikidza: A conductive gomba risingatambanudzi pamusoro pemvura yakadhindwa bhodhi.

Kuburikidza ne: A kuburikidza-gomba rinotambanuka kubva kune imwe pamusoro pebhodhi rakadhindwa kune imwe.

Chikamu chemuburi: gomba rinoshandiswa kweComponent terminals yakatarwa kuPCB uye kubatana kwemagetsi kweiyo inoitisa mifananidzo.

Mira kure: Vertical chinhambwe kubva pasi pemuviri wepamusoro pegomo chigadziro kusvika pasi pepini.
