Amathiphu angu-5 angakusiza unciphise izindleko zokukhiqiza ze-PCB.
01 Nciphisa usayizi webhodi Enye yezinto eziyinhloko ezingaba nomthelela omkhulu ezindlekweni zokukhiqiza ubukhulu bebhodi lesifunda eliphrintiwe.Uma udinga ibhodi lesifunda elikhulu, i-wiring izoba lula, kodwa izindleko zokukhiqiza nazo zizoba phezulu.ngendlela efanayo.Uma i-PCB yakho incane kakhulu,...Funda kabanzi -
Hlukanisa i-iPhone 12 ne-iPhone 12 Pro ukuze ubone ukuthi i-PCB kabani ngaphakathi
I-iPhone 12 ne-iPhone 12 Pro zisanda kwethulwa, kanti i-ejensi eyaziwa kakhulu yokudiliza i-iFixit yenza ukuhlaziya okudiliza i-iPhone 12 ne-iPhone 12 Pro.Uma sibheka imiphumela yokudilizwa kwe-iFixit, ukwakhiwa komshini omusha nezinto zokwakha kusekuhle kakhulu, ...Funda kabanzi -
Imithetho eyisisekelo yesakhiwo sengxenye
1. Ukuhlelwa ngokwamamojula wesekethe, namasekhethi ahlobene aqaphela umsebenzi ofanayo abizwa ngokuthi imojuli.Izingxenye zemojula yesifunda kufanele zamukele isimiso sokugxila okuseduze, futhi isifunda sedijithali kanye nesifunda se-analog kufanele sihlukaniswe;2. Azikho izingxenye noma amadivaysi...Funda kabanzi -
Indlela yokusebenzisa isisindo sethusi ukwenza ukukhiqizwa kwe-PCB ephezulu?
Ngenxa yezizathu eziningi, kunezinhlobo eziningi ezahlukene zamaphrojekthi wokukhiqiza we-PCB adinga izinsimbi ezithile zethusi.Sithola imibuzo evela kumakhasimende angawazi umqondo wesisindo sethusi ngezikhathi ezithile, ngakho lesi sihloko sihlose ukuxazulula lezi zinkinga.Ngaphezu kwalokho, okulandelayo...Funda kabanzi -
Naka lezi zinto mayelana "nezendlalelo" ze-PCB!.
Ukwakhiwa kwe-PCB ye-multilayer (ibhodi lesifunda eliphrintiwe) kungaba nzima kakhulu.Iqiniso lokuthi umklamo udinga ngisho nokusetshenziswa kwezingqimba ezingaphezu kwezimbili kusho ukuthi inombolo edingekayo yamasekethe ngeke ikwazi ukufakwa kuphela ezindaweni eziphezulu nangaphansi.Noma ngabe isekethe ingena...Funda kabanzi -
Imigomo yokucaciswa kwezinto ze-PCB enezingqimba eziyi-12
Izinketho zezinto ezibonakalayo ezimbalwa zingasetshenziswa ukwenza ngokwezifiso amabhodi e-PCB anezingqimba eziyi-12.Lokhu kuhlanganisa izinhlobo ezahlukene zezinto zokuqhuba, izinto zokunamathisela, izinto zokumboza, nokunye.Uma ucacisa imininingwane ebalulekile yama-PCB anezingqimba eziyi-12, ungathola ukuthi umenzi wakho usebenzisa amagama amaningi obuchwepheshe.Kumele...Funda kabanzi -
Indlela yokuklama isitaki se-PCB
Umklamo onama-laminated ngokuyinhloko uhambisana nemithetho emibili: 1. Ungqimba lwezintambo ngalunye kufanele lube nongqimba olusondelene lwereferensi (ungqimba lwamandla noma lomhlabathi);2. Ungqimba lwamandla amakhulu oluseduze kanye nongqimba lomhlabathi kufanele kugcinwe ebangeni elincane ukuze kunikeze amandla amakhulu okuhlanganisa;Okulandelayo kubala i-st...Funda kabanzi -
Unganquma kanjani ngokushesha inani lezendlalelo, izintambo kanye nesakhiwo se-PCB?
Njengoba izimfuneko zikasayizi we-PCB ziba zincane futhi zibe zincane, izidingo zokuminyana kwedivayisi ziba phezulu kakhulu, futhi idizayini ye-PCB iba nzima kakhulu.Indlela yokufeza izinga eliphezulu lesakhiwo se-PCB futhi unciphise isikhathi sokuklama, khona-ke sizokhuluma ngamakhono okuklama wokuhlela kwe-PCB, isakhiwo kanye nezintambo.Funda kabanzi -
Umehluko kanye nomsebenzi we-circuit board soldering layer kanye ne-solder mask
Isingeniso se-Solder Mask Iphedi lokumelana yi-soldermask, elibhekisela engxenyeni yebhodi lesifunda okufanele lipendwe ngamafutha aluhlaza.Eqinisweni, le maski ye-solder isebenzisa okukhiphayo okungalungile, ngakho-ke ngemva kokuma kwe-mask ye-solder kumephu ebhodini, imaski ye-solder ayipendiwe ngamafutha aluhlaza, ...Funda kabanzi -
I-PCB Plating inezindlela eziningi
Kunezindlela ezine eziyinhloko ze-electroplating kumabhodi wesekethe: i-electroplating yomugqa womunwe, i-electroplating yomgodi, i-reel-linked selective plating, kanye ne-brush plating.Nasi isingeniso esifushane: 01 Ukufakwa kwemigqa yeminwe Izinsimbi ezingandile zidinga ukupulekwa ezixhunyweni zonqenqema lwebhodi, ibhodi...Funda kabanzi -
Funda ngokushesha idizayini ye-PCB enomumo ongajwayelekile
I-PCB ephelele esiyibuka ngeso lengqondo imvamisa iwunxande ojwayelekile.Nakuba imiklamo eminingi iwunxande ngempela, imiklamo eminingi idinga amabhodi esekethe anomumo ongavamile, futhi izimo ezinjalo ngokuvamile akulula ukuziklama.Lesi sihloko sichaza indlela yokuklama ama-PCB anomumo ongajwayelekile.Namuhla, usayizi o...Funda kabanzi -
Ngembobo, imbobo eyimpumputhe, imbobo egqitshiwe, yiziphi izici zokubhola kwe-PCB emithathu?
I-Via (VIA), lena imbobo evamile esetshenziselwa ukuqhuba noma ukuxhuma imigqa ye-foil yethusi phakathi kwamaphethini e-conductive ezendlalelo ezahlukene zebhodi lesifunda.Isibonelo (njengezimbobo eziyizimpumputhe, izimbobo ezigqitshiwe), kodwa ayikwazi ukufaka umkhondo wengxenye noma izimbobo ezihlanganiswe ngethusi zezinye izinto eziqinisiwe.Ngoba...Funda kabanzi
