A PCB ibhodi lezinto ezingahambisi lapho izintambo ezishintshayo ziphrintwa khona noma ziqoshwe khona. Izinto ze-elekthronikhi ezibekwe ebhodini zixhunywe ngemigqa ukwakha isekethe yokusebenza. Ukusebenza komklamo we-PCB kuyisihluthulelo sokusebenza kwemishini, futhi kunemingcele eminingi engathinta ukusebenza kahle kwe-PCB.

Usayizi omncane wephakheji unciphisa izindleko, wenza lula ukwakheka kwe-PCB, futhi wehlise ukulahleka kokudluliswa kokuxhuma kwephoyinti nephuzu. Isikhala esincane samatheminali siholela kuzixhumi ezincane futhi, yena, amabhodi amancane nosayizi wezindiza zangemuva.

Isibonelo, isikhala esikhulayo esifanayo senhloko yesixhumi sesifazane singancishiswa, futhi nosayizi omncane wephakeji lesifazane ungasiza ukunciphisa usayizi wesixhumi.

Amanani wedatha aqhume, futhi ukulahleka kwesiginali ngesikhathi sokufakwa manje sekubucayi. Ukwakheka kwangaphakathi kanye nokugcina kwesixhumi kudlala indima ebalulekile ekwenzeni ngcono amandla esignali nokunciphisa ukulahleka kokufakwa. Ukungenisa umoya okuthuthukisiwe kanye ne-impedance yesiteshi ethuthukisiwe nakho kungathuthukisa isikhombimsebenzisi sesiginali.

Ukuvikela ukuphazanyiswa kwe-electromagnetic (EMI) nokukhishwa kwe-electrostatic (ESD) kuyisinyathelo esibalulekile sokwenza ngcono isilinganiso sedatha. Ukufakwa okukhethekile kanye nendlela yokuqeda kuqinisekisa ukuvikelwa kwi-EMI ne-ESD. Leli yiphuzu okufanele ulicabangele lapho ukhetha isixhumi se-PCB.

Kuyadingeka ukuthi ikhebula lixhunywe kahle endaweni yokudlulisela yesixhumi ukunqoba ukulahleka kwesiginali. Izixhumi ezahlukahlukene zihlanganisa amayunithi wokugcina we-wire nama-cable clip endlini eyodwa ye-plug. Ezinye izixhumi ze-PCB zinemithombo elayishwe ngaphambili ukusiza ukuvimbela ukususwa kwentambo ngengozi.
