Uyazi ukuthi yiziphi izinzuzo ze-PCB enezinombolo ezilinganayo?
[VW PCBworld] Abaklami bangase badizayine amabhodi esekethe aphrintiwe anezinombolo ezingavamile (ama-PCB). Uma i-wiring ingadingi isendlalelo esengeziwe, kungani siyisebenzisa? Ingabe ukwehlisa izendlalelo ngeke kwenze ibhodi lesifunda libe mncane? Uma kunebhodi lesifunda elilodwa elincane, ngeke yini izindleko zibe phansi? Nokho, kwezinye izimo...Funda kabanzi -
Kungani izinkampani ze-PCB zithanda i-Jiangxi yokukhulisa umthamo nokudlulisa?
[VW PCBworld] Amabhodi esekethe aphrintiwe ayizingxenye ezibalulekile zokuxhuma nge-elekthronikhi zemikhiqizo kagesi, futhi aziwa ngokuthi “umama wemikhiqizo kagesi”. Amabhodi esekethe aphrintiwe asatshalaliswa kabanzi, ahlanganisa amathuluzi okuxhumana, amakhompyutha nama-peripherals, ...Funda kabanzi -
Uyini umehluko phakathi kokufakwa kwegolide nokufakwa kwesiliva ebhodini le-PCB? Imiphumela yayimangaza
Abadlali abaningi be-DIY bazothola ukuthi imikhiqizo ehlukahlukene yebhodi emakethe isebenzisa izinhlobonhlobo ezididayo zemibala ye-PCB. Imibala evame kakhulu ye-PCB emnyama, eluhlaza, eluhlaza okwesibhakabhaka, ephuzi, ensomi, ebomvu, nensundu. Abanye abakhiqizi baye bahlakulela imibala emhlophe, epinki neminye ehlukene ye-PCB. Ngokwesiko...Funda kabanzi -
Kungani i-PCB kufanele ixhunywe ngezimbobo? Ingabe kukhona ulwazi olwaziyo?
Imbobo yokuqhuba i-Via hole yaziwa nangokuthi ngembobo. Ukuze kuhlangatshezwane nezidingo zamakhasimende, ibhodi lesekhethi ngembobo kufanele lixhunywe. Ngemuva kokuzijwayeza okuningi, inqubo yokuxhuma ye-aluminium yendabuko iyashintshwa, futhi imaski ye-solder yebhodi lesifunda kanye nokuxhuma kuqedwa nge-wh...Funda kabanzi -
Ngo-2021, isimo se-quo namathuba e-PCB yezimoto
Usayizi wemakethe yezimoto ye-PCB yasekhaya, ukusatshalaliswa kanye nesimo sokuncintisana 1. Ngokombono wemakethe yasekhaya, usayizi wemakethe wama-PCB ezimoto ungamayuan ayizigidi eziyizinkulungwane eziyi-10, futhi izindawo zokufaka izicelo ikakhulukazi amabhodi angawodwa nakabili anenani elincane lamabhodi e-HDI erada. . 2. Kuleli sonto...Funda kabanzi -
Unepheya yezandla ezihlakaniphile “ezifekethisiwe” ku-PCB yomkhumbi-mkhathi
“Umshiseli” oneminyaka engu-39 ubudala u-Wang He unezandla ezimhlophe nezintekenteke ngendlela engavamile. Eminyakeni engu-15 edlule, leli pheya lezandla ezinekhono liye labamba iqhaza ekwakhiweni kwamaphrojekthi angaphezu kwe-10 okulayisha isikhala, okuhlanganisa uchungechunge oludumile lwe-Shenzhou, uchungechunge lwe-Tiangong kanye ne-Chang'e ser...Funda kabanzi -
Ungakucabangela kanjani ukufaniswa kwe-impedance lapho uklama ama-schematics edizayini ye-PCB enesivinini esikhulu?
Lapho uklama amasekethe e-PCB anesivinini esikhulu, ukufaniswa kwe-impedance kungenye yezinto zokuklama. Inani le-impedance linobudlelwano obuphelele nendlela yokufaka izintambo, njengokuhamba phezu kwesendlalelo esingaphezulu (i-microstrip) noma isendlalelo sangaphakathi (i-stripline/double stripline), ibanga ukusuka kusendlalelo sereferensi (i-powe...Funda kabanzi -
I-Copper clad laminate iyi-substrate eyinhloko
Inqubo yokukhiqiza ye-copper clad laminate (CCL) iwukugxilisa into eqinisayo nge-organic resin bese uyomisa ukwenza i-prepreg. A blank eyenziwe prepregs eziningana laminated ndawonye, eyodwa noma zombili izinhlangothi embozwe ucwecwe yethusi, futhi impahla emise okwepuleti okwakhiwa ngokucindezela hot. F...Funda kabanzi -
Ezinye izinkinga ezinzima ezihlobene ne-PCB enesivinini esikhulu, ingabe ukuxazululile ukungabaza kwakho?
Kusuka emhlabeni we-PCB 1. Ungakucabangela kanjani ukufaniswa kwe-impedance lapho uklama ama-schematics edizayini ye-PCB enesivinini esikhulu? Lapho uklama amasekethe e-PCB anesivinini esikhulu, ukufaniswa kwe-impedance kungenye yezinto zokuklama. Inani le-impedance linobudlelwano obuphelele nendlela yokufaka izintambo, njengokuhamba phezu kwe-su...Funda kabanzi -
Yimaphi amathuba entuthuko imboni ye-PCB enawo esikhathini esizayo?
Kusuka ku-PCB World—- 01 Ukuqondiswa kwamandla okukhiqiza kuyashintsha Isiqondiso samandla okukhiqiza siwukwandisa ukukhiqiza nokwandisa umthamo, kanye nokuthuthukisa imikhiqizo, isuka kwesezingeni eliphansi iye kwephezulu.
