Incazelo yamaphuzu abalulekile enqubo yokukhiqiza yamabhodi wesekethe anezingqimba eziningi ze-PCB
Ukukhiqizwa kwamabhodi esekethe e-PCB asezingeni eliphezulu akudingi nje ukutshalwa kwezimali okuphezulu kwezobuchwepheshe nemishini, kodwa futhi kudinga ukuqoqwa kokuhlangenwe nakho kochwepheshe nabasebenzi bokukhiqiza. Kunzima kakhulu ukusetshenzwa kunamabhodi esekethe enziwe ngezingqimba eziningi, kanye nekhwalithi yawo...Funda kabanzi -
FR-4 impahla - pcb multilayer wesifunda ibhodi
Abakhiqizi bebhodi lesekethe le-Pcb elinezingqimba eziningi banethimba lochwepheshe lokucwaninga nokuthuthukiswa kwezobuchwepheshe, banolwazi olunzulu lwenqubo yobuchwepheshe bemboni, futhi banezindawo zokukhiqiza ezinokwethenjelwa, izindawo zokuhlola kanye namalabhorethri angokwenyama namakhemikhali anazo zonke izinhlobo zemisebenzi. I-FR-...Funda kabanzi -
IYINI I-PCBA ESEBENZAYO?
Ukucutshungulwa kwe-CBA kuwumkhiqizo oqediwe webhodi elingenalutho le-PCB ngemva kwepheshi ye-SMT, i-plug-in ye-DIP kanye nokuhlolwa kwe-PCBA, ukuhlolwa kwekhwalithi nenqubo yokuhlanganisa, okubizwa ngokuthi i-PCBA. Iqembu eliphathisayo iletha iphrojekthi yokucubungula efekthri yochwepheshe ye-PCBA, bese ilinda umkhiqizo ophelile...Funda kabanzi -
Iyini i-impedance yesici ku-PCB? Indlela yokuxazulula inkinga ye-impedance?
Ngokuthuthukiswa kwemikhiqizo yamakhasimende, ikhula kancane kancane ibheke kwezobuhlakani, ngakho-ke izidingo ze-PCB board impedance ziya ngokuya ziba namandla, okubuye kukhuthaze ukuvuthwa okuqhubekayo kobuchwepheshe bomklamo we-impedance. Iyini impedance yesici? 1. I-resi...Funda kabanzi -
Iyini ibhodi lesekhethi enezingqimba eziningi] Izinzuzo zamabhodi wesekethe we-PCB anezingqimba eziningi
Liyini ibhodi lesifunda elinezingqimba eziningi, futhi yiziphi izinzuzo zebhodi lesifunda le-PCB elinezingqimba eziningi? Njengoba igama liphakamisa, ibhodi lesifunda elinezingqimba eziningi lisho ukuthi ibhodi lesifunda elinezingqimba ezingaphezu kwezimbili lingabizwa ngokuthi i-multi-layer. Ngike ngahlaziya ukuthi liyini ibhodi lesifunda elinamacala amabili ngaphambili, futhi...Funda kabanzi -
I-Siemens yethule isisombululo se-PCBflow esisekelwe efwini ukusheshisa inqubo yokuthuthukiswa kwamabhodi esekethe aphrintiwe ukusuka ekuklanyeni kuya ekukhiqizeni.
Lesi sixazululo ngesokuqala embonini yokuqinisekisa ukusebenzisana okuphephile phakathi kwethimba labaklami bebhodi eliphrintiwe (PCB) nomkhiqizi Ukukhishwa kokuqala kwensizakalo yokuhlaziya ye-inthanethi ye-manufacturability (DFM) i-Siemens isanda kumemezela ukwethulwa kwe-software esungulwe ngamafu ye-solut. .Funda kabanzi -
Imboni yezimoto ezihlakaniphile eqhuba ibhodi lesifunda le-FPC eliguquguqukayo likhula ngokushesha
1 . Incazelo nokuhlukaniswa kwemboni yokukhiqiza ye-FPC i-FPC, eyaziwa nangokuthi ibhodi lesifunda le-PCB eliphrintiwe, ingenye yebhodi lesekethe ye-PCB (PCB) ephrintiwe, iyingxenye ebalulekile yokuxhumana yedivayisi kagesi yemishini kagesi. I-FPC inezinzuzo ezingenakuqhathaniswa ngaphezu kwezinye...Funda kabanzi -
Ukuqamba kuyinkosi, ikhwalithi ye-Skyworth iyathandwa
Ukuqamba kuyinkosi, ikhwalithi ye-Skyworth iyathandwa Ucwaningo lubonisa ukuthi ikhwalithi, amazwi omlomo, kanye nesevisi yizona zinto eziyinhloko ukuze abathengi bakhethe imikhiqizo, futhi ikhwalithi yiyona ebaluleke kakhulu kubantu abaningi. Izinga elihle kakhulu, izinto zikagesi ezisezingeni eliphezulu ziyilokho wonke umuntu akufunayo. Ku...Funda kabanzi -
Ukuguqula indlela yentuthuko, ukudala imikhiqizo edumile emhlabeni
Ukuguqula indlela yentuthuko, ukudala imikhiqizo edumile emhlabeni wonke Kusukela ngonyaka odlule, ngochungechunge lwezinqubomgomo zokwesekwa kwezimboni kazwelonke kanye nezinyathelo zokwandisa isidingo sasekhaya kanye nokwandisa ukutshalwa kwezimali, ukukhiqizwa nokuthengiswa kwezinto zikagesi zasendlini yaseChina kuye kwaqhubeka...Funda kabanzi
