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 -
Ubuchwepheshe bokukhiqiza ibhodi le-PCB
Amabhodi esekethe aphrintiwe (ama-PCB) avela cishe kuzo zonke izisetshenziswa zikagesi. Uma kunezingxenye ze-electronic kudivayisi, zonke zifakwe kuma-PCB osayizi abahlukahlukene. Ngokungeziwe ekulungiseni izingxenye ezincane ezihlukahlukene, umsebenzi oyinhloko we-PCB ukuhlinzeka ngoxhumano lukagesi oluhlangene lwezingxenye ezihlukahlukene ze-p...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.

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 -
Isimo samanje namathuba we-PCB yezimoto ngo-2021
Usayizi wemakethe yezimoto ze-PCB yasekhaya, ukusabalalisa kanye nephethini yokuncintisana 1. Njengamanje, ngokombono wemakethe yasekhaya, usayizi wemakethe we-PCB yezimoto ungamayuan ayizigidi eziyizinkulungwane eziyi-10, futhi izinkundla zokufaka isicelo ikakhulukazi amabhodi angawodwa nakabili anenani elincane le-HDI. amabhodi we-r...Funda kabanzi -
Ukudluliswa kwemboni ye-PCB ukusheshisa umholi we-PCB ukuhlangabezana nethuba lokukhula
I-PCB Industry iya ngasempumalanga, izwekazi liwumbukiso oyingqayizivele. Isikhungo samandla adonsela phansi embonini ye-PCB silokhu sishintshela e-Asia, futhi amandla okukhiqiza e-Asia aqhubekela phambili ashintshela ezweni elikhulu, enza iphethini entsha yezimboni.
