Izinkinga eziyisishiyagalombili ezijwayelekile nezisombululo ekwakhiweni kwe-PCB
Enqubweni yokuklama nokukhiqiza kwe-PCB, onjiniyela abadingi nje kuphela ukuvimbela izingozi ngesikhathi sokukhiqiza i-PCB, kodwa futhi kudingeka bagweme amaphutha okuklama.Lesi sihloko sifinyeza futhi sihlaziye lezi zinkinga ezijwayelekile ze-PCB, ngethemba lokuletha usizo oluthile emsebenzini wawo wonke wokwakha nomsebenzi wokukhiqiza....Funda kabanzi -
Izinzuzo zenqubo yokuphrinta ye-PCB
Kusuka ku-PCB World.Ubuchwepheshe bokuphrinta be-inkjet bamukelwe kabanzi ukuze kumakwe amabhodi esekethe e-PCB nokuphrinta uyinki yemaski ye-solder.Esikhathini sedijithali, isidingo sokufunda ngokushesha amakhodi onqenqemeni ngebhodi-by-board kanye nokukhiqizwa okusheshayo nokuphrinta amakhodi e-QR kwenze ...Funda kabanzi -
I-Thailand ithatha ama-40% omthamo wokukhiqiza we-PCB yaseNingizimu-mpumalanga ye-Asia, ibalwa kwabayishumi abahamba phambili emhlabeni.
Kusuka ku-PCB World.Isekelwa iJapane, ukukhiqizwa kwezimoto zaseThailand kwake kwaqhathaniswa nokwaseFrance, kwathatha indawo yerayisi nenjoloba ukuze kube imboni enkulu kunazo zonke eThailand.Zombili izinhlangothi zeBangkok Bay zikleliswe ngolayini bokukhiqiza izimoto iToyota, Nissan kanye neLexus, i-sc abilayo...Funda kabanzi -
Umehluko phakathi kwefayela le-PCB schematic ne-PCB design
Kusuka ku-PCBworld Uma ukhuluma ngamabhodi esekethe aphrintiwe, abaqalayo bavame ukudida "izinhlelo ze-PCB" kanye "namafayela e-PCB design", kodwa empeleni babhekisela ezintweni ezahlukene.Ukuqonda umehluko phakathi kwabo kuyisihluthulelo sokukhiqiza ngempumelelo ama-PCB, ukuze kube...Funda kabanzi -
Mayelana nokubhaka kwe-PCB
1. Uma ubhaka ama-PCB anosayizi omkhulu, sebenzisa uhlelo lokupakisha oluvundlile.Kunconywa ukuthi inani eliphezulu lesitaki akufanele lidlule izingcezu ezingu-30.Ihhavini idinga ukuvulwa phakathi kwemizuzu eyi-10 ngemuva kokubhaka ukukhipha i-PCB futhi uyibeke phansi ukuze uyipholise.Ngemva kokubhaka, idinga ukucindezelwa...Funda kabanzi -
Kungani ama-PCB aphelelwe yisikhathi edinga ukubhakwa ngaphambi kwe-SMT noma isithando somlilo?
Inhloso enkulu yokubhaka kwe-PCB ukukhipha umswakama nokususa umswakama, kanye nokukhipha umswakama oqukethwe ku-PCB noma omuncwa ngaphandle, ngoba ezinye izinto ezisetshenziswa ku-PCB ngokwayo zakha kalula ama-molecule amanzi.Ngaphezu kwalokho, ngemva kokukhiqizwa kwe-PCB futhi yabekwa isikhathi esithile, i...Funda kabanzi -
Izici zephutha nokugcinwa komonakalo we-circuit board capacitor
Okokuqala, iqhinga elincane lokuhlola i-multimeter yezingxenye ze-SMT Ezinye izakhi ze-SMD zincane kakhulu futhi akulula ukuzihlola nokulungisa ngamapeni e-multimeter ajwayelekile.Enye iwukuthi kulula ukubangela isifunda esifushane, kanti enye ukuthi akulula ebhodini lesifunda elihlanganiswe ne-insulatin...Funda kabanzi -
Khumbula la maqhinga okulungisa, ungalungisa ukwehluleka okungu-99% kwe-PCB
Ukwehluleka okubangelwa ukulimala kwe-capacitor kuphezulu kakhulu emishinini kagesi, futhi ukulimala kwama-electrolytic capacitor yikhona okuvamile.Ukusebenza kokulimala kwe-capacitor kungokulandelayo: 1. Ikhono liba lincane;2. Ukulahlekelwa amandla ngokuphelele;3. Ukuvuza;4. Isifunda esifushane.Ama-Capacitor ayadlala...Funda kabanzi -
Izixazululo zokuhlanzwa okufanele imboni ye-electroplating izazi
Kungani ukuhlanza?1. Ngesikhathi sokusetshenziswa kwesisombululo se-electroplating, imikhiqizo ephilayo iyaqhubeka nokuqongelela 2. I-TOC (Inani Eliphelele Lokungcola Kwezinto Eziphilayo) liyaqhubeka nokukhuphuka, okuzoholela ekwandeni kwenani le-electroplating brightener kanye ne-agent yokulinganisa engeziwe 3. Amaphutha ku- kufakwe ugesi...Funda kabanzi -
Amanani e-foil yethusi ayenyuka, futhi ukwanda sekube yisivumelwano embonini ye-PCB
Umthamo wasekhaya we-high-frequency kanye ne-high-speed copper clad laminate akwanele.Imboni ye-copper foil iyimboni enkulu, ubuchwepheshe, kanye nethalente elinezithiyo eziphezulu zokungena.Ngokusho kwezinhlelo zokusebenza ezihlukene ezingezansi, imikhiqizo ye-copper foil ingahlukaniswa ...Funda kabanzi -
Yimaphi amakhono okuklama we-op amp circuit PCB?
Izintambo zebhodi lesifunda eliphrintiwe (PCB) zidlala indima ebalulekile kumasekhethi anesivinini esikhulu, kodwa ngokuvamile kuba ngesinye sezinyathelo zokugcina enqubweni yokuklama isifunda.Kunezinkinga eziningi ngezintambo ze-PCB ezinesivinini esikhulu, futhi kubhalwe izincwadi eziningi ngalesi sihloko.Lesi sihloko sidingida kakhulu izintambo ze ...Funda kabanzi -
