- Ukuhlolwa Kokulawulwa Kwe-Impedans kwebhodi le-PCB
Ukuhlola kwe-TDR okwamanje kusetshenziswa kakhulu kubakhiqizi bebhodi lesekhethi yebhethri ye-PCB (amabhodi esekethe ephrintiwe) imigqa yesignali nokuhlolwa kokuvinjwa kwedivayisi.Kunezizathu eziningi ezithinta ukunemba kokuhlolwa kwe-TDR, ikakhulukazi ukubonisa, ukulinganisa, ukukhetha ukufunda, njll. Ukuzindla kuzodala ukuphambuka okukhulu kunani lokuhlola lomugqa wesignali we-PCB omfushane, ikakhulukazi uma kusetshenziswa i-TIP (probe) ...
- Ibhodi Lesifunda Eliphrintiwe |Okubalulekile, FR4
Esivame ukubhekisela kukho ukuthi "FR-4 Fiber Class Material PCB Board" igama lekhodi lebanga lezinto ezingashi.Imele ukucaciswa kwezinto ezibonakalayo okumele i-resin ikwazi ukuzicisha ngokwayo ngemva kokushiswa.Akulona igama eliphathekayo, kodwa uhlobo lwezinto ezibonakalayo.Ibanga lezinto ezibonakalayo, ngakho-ke kunezinhlobo eziningi zezinto zebanga le-FR-4 ezisetshenziswa kumabhodi wesifunda ajwayelekile njengamanje, kodwa...
- Ibhodi Lesifunda Eliphrintiwe |Ukucwenga Ngembobo, Imbobo Eyimpumputhe, Umgodi Ombelwe
Ibhodi lesifunda eliphrintiwe lakhiwe ngezingqimba zamasekethe e-foil yethusi, futhi ukuxhumana phakathi kwezingqimba ezihlukene zesekethe kuncike kulezi "vias".Lokhu kungenxa yokuthi ukukhiqizwa kwebhodi lesifunda lanamuhla lisebenzisa izimbobo ezibhoboziwe ukuxhuma amasekhethi ahlukene.Phakathi kwezingqimba zesifunda, kufana nesiteshi sokuxhuma somzila wamanzi ongaphansi komhlaba onezingqimba eziningi.Abangane abadlale ividyo ethi "Brother Mary"...
- Ibhodi Lesifunda Eliphrintiwe |Ukwethulwa kweSilkscreen
Iyini i-Silkscreen ku-PCB?Uma uklama noma u-oda amabhodi esekethe akho aphrintiwe, ingabe udinga ukukhokha okwengeziwe ngesikrini sikasilika?Kukhona imibuzo odinga ukuyazi ukuthi yini isikrini sikasilika?Futhi isikrini sikasilika sibaluleke kangakanani ekwenziweni kwebhodi lakho le-PCB noma i-Printed Circuit Board Assembly?Manje i-ABIS izokuchazela.Yini isikrini sikasilika?Isikrini sikasilika ungqimba lwemikhondo kayinki esetshenziselwa ukuhlonza izingxenye, ...
- I-HDI board-high density interconnect
Ibhodi le-HDI, ukuminyana okuphezulu kokuxhumana okuphrintiwe ibhodi lesifunda Amabhodi e-HDI angobunye bobuchwepheshe obukhula ngokushesha kuma-PCB futhi manje butholakala e-ABIS Circuits Ltd. Amabhodi e-HDI aqukethe ama-vias angaboni kanye/noma angcwatshwe, futhi ngokuvamile aqukethe ama-microvias angu-0.006 noma amancane ububanzi.Banobuningi besifunda obuphakeme kunamabhodi wesifunda wendabuko.Kunezinhlobo eziyisi-6 ezihlukene zamabhodi we-HDI PCB, ukusuka phezulu kuye ku-su...
- Indlela yokuvimbela i-PCB board warping ngesikhathi senqubo yokukhiqiza
I-SMT(Printed Circuit Board Assembly, PCBA) ibizwa nangokuthi ubuchwepheshe be-surface mount.Phakathi nenqubo yokukhiqiza, i-solder paste iyashiswa futhi incibilike endaweni yokushisa, ukuze amaphedi e-PCB ahlanganiswe ngokuthembekile nezingxenye ze-surface mount ngokusebenzisa i-solder paste alloy.Le nqubo siyibiza ngokuthi i-reflow soldering.Iningi lamabhodi esekethe lithambekele ekugobeni nasekwenzeni ibhodi uma lihlehliswa...
- Indlela yokwenza i-pcb kuphaneli?
1. Uhlaka lwangaphandle (uhlangothi olubambayo) lwephaneli Yebhodi Lesifunda Eliphrintiwe kufanele lusebenzise idizayini evala iluphu ukuze kuqinisekiswe ukuthi ijigsaw ye-PCB ngeke ikhubazekile ngemva kokulungiswa endaweni;2. Ububanzi bephaneli ye-PCB ≤260mm (umugqa we-SIEMENS) noma ≤300mm (umugqa we-FUJI);uma ukukhishwa okuzenzakalelayo kuyadingeka, ububanzi bephaneli ye-PCB× ubude ≤125 mm×180 mm;3. Umumo we-PCB jigsaw kufanele usondele eduze kwesikwele ngokungenzeka...
