Iibhodi zeesekethengamacandelo angundoqo weiimveliso zombane.Makhe sijonge amacandelo eebhodi zesekethe:
1. Iphedi:
IiPads yimingxuma yentsimbi esetyenziselwa ukuthengisa izikhonkwane zecandelo.
2 umaleko:
Ngokuxhomekeke kuyilo lwebhodi yesiphaluka, kuya kubakho i-double-side, i-4-layer, i-6-layer, i-8-layer, njl.Ukongeza kumaleko wesignali, kukho ezinye iileyile ezisetyenziselwa ukuchaza ukusetyenzwa.
3. Nge:
Intsingiselo ye-vias kukuba ukuba isiphaluka asikwazi ukuphumeza zonke iimpawu zesignali kwinqanaba elinye, imigca yesignali kufuneka idityaniswe kwiileya ngokusebenzisa.IiVias ngokubanzi zahlulwe zaba ziindidi ezimbini, enye yintsimbi nge, enye ingeyiyo eyentsimbi.Isinyithi ngesinyithi sisetyenziselwa ukudibanisa izikhonkwane zecandelo phakathi kweeleya.Ubume kunye nedayamitha ye-via ixhomekeke kwiimpawu zomqondiso kunye neemfuno zeplanti yokucubungula.
4. Amacandelo:
Amacandelo athengiswa kwi-PCB.Ukudityaniswa koyilo phakathi kwamacandelo ahlukeneyo kunokufikelela kwimisebenzi eyahlukeneyo, ekwayindima yePCB.
5. Uyilo:
Uyilo lubhekiselele kumgca wesignali odibanisa izikhonkwane zesixhobo.Ubude kunye nobubanzi boyilo buxhomekeke kubume bomqondiso, njengobungakanani bangoku, isantya, njl.
6. Ushicilelo lweSkrini:
Isikrini Ushicilelo lusenokuthiwa yiscreen Umaleko woShicilelo, osetyenziselwa ukuphawula ulwazi olwahlukeneyo olunxulumeneyo kumacandelo.Ushicilelo lwesikrini lumhlophe ngokubanzi, kwaye unokukhetha umbala ngokwezidingo zakho.
7. Imaski yesoda:
Umsebenzi oyintloko we-mask solder kukukhusela umphezulu we-PCB, yenza umaleko okhuselayo kunye nobukhulu obuthile, kwaye uthintele ukudibanisa phakathi kobhedu nomoya.Imaski yesolder iluhlaza ngokubanzi, kodwa kukwakho nobomvu, tyheli, luhlaza, mhlophe, kunye nomnyama.
8. Umngxuma wokumisa:
Umngxuma wokumisa ngumngxuma obekwe ngokufanelekileyo ukufakela okanye ukulungisa ingxaki.
9. Ukuzalisa:
Ukuzaliswa kobhedu kusetyenziswe kumnatha womhlaba, onokuthi unciphise ngempumelelo i-impedance.
10. Imida yombane:
Umda wombane usetyenziselwa ukumisela imilinganiselo yebhodi yesekethe, kwaye onke amacandelo ebhodini yesekethe akufanele adlule lo mda.
Ezi nxalenye zingentla zilishumi zisisiseko sokuqulunqwa kwebhodi yesekethe, kwaye ukufezekiswa kwemisebenzi emininzi kusafuneka kucwangciswe kwi-chip ukufezekisa.
Ukuba unayo nayiphi na imibuzo, wamkelekile ukuba undwendwelePCBFuture.com.
