Indlela yokuxhuma isixhumi se-PCB
Njengengxenye ebalulekile yawo wonke umshini, i-PCB ngokuvamile ayikwazi ukwakha umkhiqizo we-elekthronikhi, futhi kufanele kube nenkinga yokuxhuma kwangaphandle.Isibonelo, ukuxhumeka kukagesi kuyadingeka phakathi kwama-PCB, ama-PCB nezingxenye zangaphandle, ama-PCB namaphaneli emishini.Ingenye yezinto ezibalulekile c...Funda kabanzi -
I-PCBA Reverse Engineering
Inqubo yokugcwaliseka kobuchwepheshe yebhodi lokukopisha le-PCB iwukuskena ibhodi lesifunda ukuze likopishwe, ukurekhoda indawo enemininingwane yendawo, bese ususa izingxenye zokwenza incwadi yezinto zokwakha (BOM) futhi uhlele ukuthengwa kwezinto ezibonakalayo, ibhodi elingenalutho Isithombe esiskeniwe icutshungulwe yi-copy boa...Funda kabanzi -
Ukuze ufinyelele lawa maphuzu angu-6, i-PCB ngeke igobe futhi isonte ngemva kwesithando somlilo sokugeleza kabusha!
Ukugoba nokusonteka kwebhodi le-PCB kulula ukwenzeka esithandweni somlilo.Njengoba sonke sazi, indlela yokuvimbela ukugoba kanye ne-warping yebhodi le-PCB ngokusebenzisa isithando somlilo se-backwelding kuchazwe ngezansi: 1. Ukunciphisa ithonya lokushisa ekucindezelekeni kwebhodi le-PCB Njengoba "izinga lokushisa" liyi-ma...Funda kabanzi -
Imihlahlandlela yabangenele-Izicaciso ze-PCB Postcure!
I. I-PCB Control Specification 1. Ukuqaqa kanye nokugcinwa kwe-PCB(1) Ibhodi le-PCB elivalwe futhi lingavulwa lingasetshenziswa ngokuqondile ku-inthanethi phakathi nezinyanga ezi-2 zosuku lokukhiqiza(2) Usuku lokukhiqiza lwebhodi le-PCB luphakathi kwezinyanga ezi-2, futhi usuku lokukhulula kufanele limakwe. ngemuva kokukhipha (3) ukukhiqizwa kwebhodi le-PCB ...Funda kabanzi -
Yiziphi izindlela zokuhlola ibhodi lesifunda?
Ibhodi le-PCB eliphelele lidinga ukudlula ezinqubweni eziningi ukusuka kumklamo kuye kumkhiqizo ophelile.Uma zonke izinqubo sezimi ngomumo, izogcina ingene kusixhumanisi sokuhlola.Amabhodi e-PCB ahloliwe kuphela azosetshenziswa emkhiqizweni, ngakho-ke uwenza kanjani umsebenzi wokuhlola ibhodi lesifunda le-PCB , Lokhu kuphezulu...Funda kabanzi -
Uyazi ukuthi kunezinhlobo eziningi ze-PCB aluminium substrates?
I-PCB aluminium substrate inamagama amaningi, i-aluminium cladding, i-aluminium PCB, ibhodi le-metal clad ephrintiwe yesifunda (MCPCB), i-PCB ephethe ukushisa, njll. Inzuzo ye-PCB aluminium substrate iwukuthi ukuchithwa kokushisa kungcono kakhulu kunesakhiwo esijwayelekile se-FR-4, kanye ne-dielectric esetshenziswa i...Funda kabanzi -
Uyazi ukuthi yiziphi izinzuzo ze-Multilayer PCB?
Ekuphileni kwansuku zonke, ibhodi lesifunda le-PCB elinezingqimba eziningi liwuhlobo lwebhodi lesifunda olusetshenziswa kakhulu.Ngengxenye ebaluleke kangaka, kufanele izuze ezinhlelweni eziningi zebhodi lesifunda le-PCB elinezingqimba eziningi.Ake sibheke izinzuzo.Izinzuzo zohlelo lokusebenza lwe-multi-lay...Funda kabanzi -
Kufanele uxhume i-vias ye-PCB, hlobo luni lolwazi lolu?
Imbobo yokuqhuba i-Via hole yaziwa nangokuthi ngembobo.Ukuze kuhlangatshezwane nezidingo zamakhasimende, ibhodi lesekethe ngembobo kufanele lixhunywe.Ngemuva kokuzijwayeza okuningi, inqubo yendabuko yokuxhuma i-aluminium iyashintshwa, futhi imaski yebhodi lesifunda ye-solder kanye nokuxhuma kuqedwa ngami mhlophe...Funda kabanzi -
Indlela “yokupholisa” kahle ibhodi lesifunda le-PCB
Ukushisa okukhiqizwa yimishini ye-elekthronikhi ngesikhathi sokusebenza kubangela ukuthi izinga lokushisa langaphakathi lemishini likhuphuke ngokushesha.Uma ukushisa kungaqedwa ngesikhathi, okokusebenza kuzoqhubeka nokushisa, idivayisi izohluleka ngenxa yokushisa ngokweqile, futhi ukuthembeka kwemishini kagesi kuzokwenza...Funda kabanzi -
Ukusebenza kwe-aluminium substrate kanye nenqubo yokuqeda phezulu
I-aluminium substrate iyi-laminate egqoke ithusi esekelwe ensimbi enomsebenzi omuhle wokulahla ukushisa.Yinto efana nepuleti eyenziwe ngendwangu ye-electronic glass fiber cloth noma ezinye izinto eziqinisayo ezifakwe inhlaka, inhlaka eyodwa, njll. njengongqimba olunamathelayo oluvikelayo, olumbozwe ngefoyili yethusi...Funda kabanzi -
Uyazi ngokuthembeka okuphezulu kwe-PCB?
Kuyini ukwethembeka?Ukwethembeka kubhekisela “kokuthenjwayo” kanye “nokwethenjwa”, futhi kubhekisela ekhonweni lomkhiqizo lokwenza umsebenzi othile ngaphansi kwezimo ezithile futhi phakathi nesikhathi esinqunyiwe.Emikhiqizweni yokugcina, lapho ukuthembeka kuphezulu, kulapho i-guaran yokusetshenziswa iphezulu...Funda kabanzi -
