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 ama-multimeter ezingxenyeni ze-SMT Ezinye izingxenye 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 kwesixazululo se-electroplating, imikhiqizo ephilayo iyaqhubeka nokuqongelela 2. I-TOC (Inani Eliphelele Lokungcola Kwemvelo) 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 -
Ungahlulela inqubo yendawo ye-PCB ngokubheka umbala
nali igolide nethusi kumabhodi esekethe omakhalekhukhwini namakhompyutha. Ngakho-ke, intengo yokugaywa kabusha kwamabhodi esekethe asetshenzisiwe ingafinyelela ngaphezu kwamayuan angama-30 ngekhilogremu. Kubiza kakhulu kunokuthengisa amaphepha alahliwe, amabhodlela engilazi, nezinsimbi ezilahliwe. Kusukela ngaphandle, ungqimba lwangaphandle lwe...Funda kabanzi -
Ubudlelwano obuyisisekelo phakathi kwesakhiwo ne-PCB 2
Ngenxa yezimpawu zokushintsha kwamandla kagesi, kulula ukubangela ukushintshwa kwamandla kagesi ukukhiqiza ukuphazamiseka okukhulu kokuhambisana kwe-electromagnetic. Njengonjiniyela wokuphakela amandla, unjiniyela ohambelana nogesi, noma unjiniyela wesakhiwo se-PCB, kufanele uqonde i-cau...Funda kabanzi -
Kunobudlelwane obuyisisekelo obufika ku-29 phakathi kwesakhiwo ne-PCB!
Ngenxa yezimpawu zokushintsha kwamandla kagesi, kulula ukubangela ukushintshwa kwamandla kagesi ukukhiqiza ukuphazamiseka okukhulu kokuhambisana kwe-electromagnetic.

Zingaki izinhlobo ze-PCB zebhodi lesifunda ezingahlukaniswa ngokwezinto ezibonakalayo? Zisetshenziswa kuphi?
Isigaba sezinto ezibonakalayo ze-PCB ikakhulukazi sihlanganisa lokhu okulandelayo: i-bai isebenzisa i-FR-4 (isisekelo sendwangu yengilazi ye-fiber), i-CEM-1/3 (i-glass fiber kanye ne-substrate eyinhlanganisela yephepha), i-FR-1 (i-copper-clad clad laminate), isisekelo sensimbi. Ama-laminates ane-Copper clad (ikakhulukazi asekelwe ku-aluminium, ambalwa asekelwe ensimbi) yiwona ...Funda kabanzi -
Igridi yethusi noma ithusi eliqinile? Lena inkinga ye-PCB okufanele ucabange ngayo!
Liyini ithusi? Okubizwa ngokuthi ukuthululela kwethusi ukusebenzisa indawo engasetshenziswanga ebhodini lesifunda njengendawo yokubhekisela bese uyigcwalisa ngethusi eliqinile. Lezi zindawo zethusi zibizwa nangokuthi ukugcwaliswa kwethusi. Ukubaluleka kwe-copper coating ukunciphisa i-impedance yocingo oluphansi kanye nokwenza ngcono ...Funda kabanzi -
Ngezinye izikhathi kunezinzuzo eziningi ku-PCB yethusi yokucwenga phansi
Enqubweni yokuklama ye-PCB, abanye onjiniyela abafuni ukubeka ithusi phezu kwawo wonke ungqimba olungezansi ukuze bonge isikhathi. Ingabe lokhu kulungile? Ingabe i-PCB kufanele ifakwe i-copper plated? Okokuqala, sidinga ukucaca: i-copper plating engezansi inenzuzo futhi iyadingeka ku-PCB, kodwa ...Funda kabanzi
