Yenziwa kanjani isendlalelo sangaphakathi se-PCB
Ngenxa yenqubo eyinkimbinkimbi yokukhiqiza i-PCB, ekuhleleni nasekwakheni ukukhiqiza okuhlakaniphile, kuyadingeka ukucabangela umsebenzi ohlobene wenqubo nokuphatha, bese kwenziwa okuzenzakalelayo, ulwazi kanye nesakhiwo esihlakaniphile.Ukuhlukaniswa kwenqubo Ngokwenombolo...Funda kabanzi -
Izidingo zenqubo yokufaka izintambo ze-PCB (zingasethwa emithethweni)
(1) Ulayini Ngokuvamile, ububanzi bomugqa wesignali bungu-0.3mm (12mil), ububanzi bomugqa wamandla bungu-0.77mm (30mil) noma 1.27mm (50mil);ibanga phakathi komugqa nomugqa kanye nephedi likhulu noma lilingana no-0.33mm (13mil) ).Kuzicelo ezingokoqobo, khulisa ibanga lapho izimo zivuma;Nini...Funda kabanzi -
Imibuzo ye-HDI PCB Design
1. Yiziphi izici okufanele ibhodi lesekethe i-DEBUG iqale kuzo?Mayelana namasekhethi edijithali, qala ngokunquma izinto ezintathu ngokulandelana kwazo: 1) Qinisekisa ukuthi wonke amanani wamandla ahlangabezana nezidingo zokuklama.Amanye amasistimu anezinto eziningi zamandla angase adinge ukucaciswa okuthile kwe-oda ...Funda kabanzi -
High frequency PCB design probelm
1. Ungabhekana kanjani nokungqubuzana kwethiyori kuzintambo zangempela?Ngokuyisisekelo, kulungile ukuhlukanisa nokuhlukanisa umhlabathi we-analog/digital.Kumele kuqashelwe ukuthi umkhondo wesignali akufanele uwele umsele ngangokunokwenzeka, futhi indlela yamanje yokubuya yokunikezwa kwamandla kanye nesignali akufanele...Funda kabanzi -
Idizayini ye-PCB eyimvamisa ephezulu
1. Ungakhetha kanjani ibhodi le-PCB?Ukukhethwa kwebhodi le-PCB kufanele kube nebhalansi phakathi kwezidingo zedizayini yokuhlangabezana nokukhiqizwa ngobuningi nezindleko.Izidingo zokuklama zihlanganisa izingxenye zikagesi nezemishini.Le nkinga yezinto ezibonakalayo ngokuvamile ibaluleke kakhulu lapho uklama amabhodi e-PCB anesivinini esikhulu (imvamisa...Funda kabanzi -
Uyini umehluko phakathi kokufakwa kwegolide nesiliva ku-PCB?
Abadlali abaningi be-DIY bazothola ukuthi imibala ye-PCB esetshenziswa imikhiqizo ehlukahlukene yebhodi emakethe iyakhazimula.Imibala evame kakhulu ye-PCB emnyama, eluhlaza, eluhlaza okwesibhakabhaka, ephuzi, ensomi, ebomvu nensundu.Abanye abakhiqizi bathuthukise ngobuhlakani ama-PCB emibala ehlukene njengomhlophe nopinki.Kwezamasiko...Funda kabanzi -
Zifundise ukuthi ungahlulela kanjani ukuthi i-PCB ingeyeqiniso
-PCBworld Ukushoda kwezinto zikagesi kanye nokunyuka kwentengo.Inikeza amathuba kubazenzisi.Kulezi zinsuku, izakhi ze-elekthronikhi ezingamanga sezidumile.Ama-fake amaningi afana nama-capacitor, resistors, inductors, amashubhu e-MOS, namakhompyutha e-single-chip azungeza...Funda kabanzi -
Kungani uxhuma ama-vias e-PCB?
Imbobo yokuqhuba i-Via hole yaziwa nangokuthi ngembobo.Ukuze kuhlangatshezwane nezidingo zamakhasimende, ibhodi lesekethe ngembobo kufanele lixhunywe.Ngemuva kokuzijwayeza okuningi, inqubo yendabuko yokuxhuma i-aluminium iyashintshwa, futhi imaski yebhodi lesifunda ye-solder kanye nokuxhuma kuqedwa ngami mhlophe...Funda kabanzi -
Ukungaqondi kahle 4: Idizayini yamandla aphansi
