Indlela yoqhagamshelo lwePCB
Njengenxalenye ebalulekileyo yomatshini wonke, i-PCB ngokubanzi ayinakho ukwenza imveliso yombane, kwaye kufuneka kubekho ingxaki yoqhagamshelwano lwangaphandle.Umzekelo, uqhagamshelo lombane luyafuneka phakathi kweePCB, iiPCB kunye namacandelo angaphandle, iiPCB kunye neepaneli zezixhobo.Yenye yezinto ezibalulekileyo c...Funda ngokugqithisileyo -
PCBA Reverse Engineering
Inkqubo yokuqonda yobugcisa yebhodi yekopi yePCB kukuskena nje ibhodi yesekethe ukuba ikhutshelwe, ukurekhoda indawo yecandelo elineenkcukacha, emva koko ususe amacandelo ukwenza ibhili yezixhobo (BOM) kwaye ulungiselele ukuthengwa kwezinto, ibhodi engenanto ngumfanekiso oskeniweyo. igqitywe yi copy boa...Funda ngokugqithisileyo -
Ukufikelela kula manqaku ma-6, iPCB ayizugotywa kwaye ijijwe emva kwesithando somlilo!
Ukugoba kunye warping yebhodi PCB kulula ukuba kwenzeke eziko backwelding.Njengoko sonke siyazi, indlela yokuthintela ukugoba kunye warping ibhodi PCB ngokusebenzisa eziko backwelding ichazwe ngezantsi: 1. Ukunciphisa ifuthe lobushushu kwi PCB ibhodi uxinzelelo Ekubeni "ubushushu" yi ma...Funda ngokugqithisileyo -
Izikhokelo zabangeneleli–Iinkcukacha zePCB Postcure!
I. PCB Control Specification 1. PCB ukukhulula kunye nokugcinwa(1) PCB ibhodi etywiniweyo nengavulwanga inokusetyenziswa ngokuthe ngqo kwi-intanethi phakathi kweenyanga ezi-2 zomhla wokwenziwa (2) Umhla wokwenziwa kwebhodi yePCB ungaphakathi kweenyanga ezi-2, kwaye umhla wokukhutshwa kufuneka uphawulwe. emva kokukhupha (3) ukwenziwa kwebhodi yePCB ...Funda ngokugqithisileyo -
Zeziphi iindlela zokuhlola ibhodi yesekethe?
Ibhodi yePCB epheleleyo kufuneka idlule kwiinkqubo ezininzi ukusuka kuyilo ukuya kwimveliso egqityiweyo.Xa zonke iinkqubo zisendaweni, ekugqibeleni iya kungena kwikhonkco lokuhlola.Kuphela iibhodi ze-PCB ezivavanyiweyo ziya kusetyenziswa kwimveliso, ngoko ke unokwenza njani umsebenzi wokuhlola ibhodi yesekethe ye-PCB , Oku kuphezulu...Funda ngokugqithisileyo -
Ngaba uyazi ukuba kukho iintlobo ezininzi zePCB aluminiyam substrates?
I-PCB aluminiyam substrate inamagama amaninzi, i-aluminium cladding, i-aluminium PCB, i-metal clad eprintiweyo ibhodi yesekethe (MCPCB), i-PCB eqhuba ukushisa, njl njl. Inzuzo ye-PCB ye-aluminium substrate kukuba ukuchithwa kobushushu kubhetele kakhulu kunokwakheka kwe-FR-4 eqhelekileyo, kunye ne-dielectric esetyenzisiweyo ...Funda ngokugqithisileyo -
Ngaba uyazi ukuba zeziphi iingenelo ze-Multilayer PCB?
Kubomi bemihla ngemihla, ibhodi yesekethe ye-multi-layer PCB okwangoku lolona hlobo lwebhodi yesekethe lusetyenziswa kakhulu.Ngomlinganiselo obalulekileyo onjalo, kufuneka uzuze kwiinzuzo ezininzi zebhodi yesekethe ye-PCB enemigangatho emininzi.Makhe sijonge iingenelo.Uncedo lwesicelo se-multi-lay...Funda ngokugqithisileyo -
Kufuneka ufake i-vias ye-PCB, luhlobo luni lolwazi olu?
Umngxuma ohambisa i-Via yaziwa ngokuba ngomngxuma.Ukuze kuhlangatyezwane neemfuno zabathengi, ibhodi yesekethe ngomngxuma kufuneka iplagwe.Emva kokuziqhelanisa okuninzi, inkqubo ye-aluminiyam yesiqhelo yokuplaga iyatshintshwa, kwaye imaski yebhodi yesekethe yomphezulu we-solder kunye nokuplaga kugqitywe ngomhlophe kum...Funda ngokugqithisileyo -
Indlela "yokupholisa" kakuhle ibhodi yesekethe yePCB
Ubushushu obuveliswa zizixhobo zombane ngexesha lokusebenza kubangela ukuba ukushisa kwangaphakathi kwezixhobo kunyuke ngokukhawuleza.Ukuba ubushushu abuchithwanga ngexesha, izixhobo ziya kuqhubeka zifudumeza, isixhobo siya kusilela ngenxa yokushisa okukhulu, kunye nokuthembeka kwesixhobo sombane siya ...Funda ngokugqithisileyo -
