- Uyenza njani ipcb kwiphaneli?
1. Ifreyim yangaphandle (icala elibambekayo) lephaneli yeBhodi yeSekethe eShicileleyo kufuneka yamkele uyilo lwe-loop evaliweyo ukuqinisekisa ukuba ijigsaw yePCB ayisayi konakala emva kokulungiswa kwifixture;2. PCB panel ububanzi ≤260mm (SIEMENS umgca) okanye ≤300mm (FUJI line);ukuba ukukhutshwa okuzenzekelayo kuyadingeka, ububanzi bepaneli yePCB × ubude ≤125 mm×180 mm;3. Ubume bejigsaw yePCB kufuneka ibe kufutshane nesikwere kangangoko...
- Ukuthintela njani ukungqubana kwebhodi yePCB ngexesha lenkqubo yokuvelisa
I-SMT (iNdibano yeBhodi yeSekethe eShicileleyo, i-PCBA) ikwabizwa ngokuba yi-surface Mount technology.Ngexesha lenkqubo yokuvelisa, i-solder paste iyafudumala kwaye inyibilike kwindawo yokufudumala, ukwenzela ukuba iipadi ze-PCB zidibaniswe ngokuthembekileyo kunye nezixhobo zokunyuka komphezulu ngokusebenzisa i-solder paste alloy.Le nkqubo siyibiza ngokuba yireflow soldering.Uninzi lweebhodi zesekethe zithande ukugoba kunye nokujija ibhodi xa unde...
- HDI ibhodi-high ingxinano uqhagamshelwano
Ibhodi ye-HDI, ibhodi ye-HDI yoxinaniso oluphezulu oluprintiweyo ibhodi yesekethe iibhodi ze-HDI yenye yezona zinto zikhula ngokukhawuleza kwiiteknoloji kwi-PCB kwaye ngoku zifumaneka kwi-ABIS Circuits Ltd. Iibhodi ze-HDI ziqulethe ii-vias ezingaboniyo kunye / okanye zingcwatywe, kwaye ngokuqhelekileyo ziqulethe i-microvias ye-0.006 okanye i-diameter encinci.Banoxinzelelo lwesekethe ephezulu kuneebhodi zesekethe zemveli.Kukho 6 iintlobo ezahlukeneyo HDI iibhodi PCB, ukusuka kumphezulu ukuya su ...
- Ibhodi yeSekethe eprintiweyo |Intshayelelo yeSilkscreen
Yintoni iSilkscreen kwiPCB?Xa uyila okanye u-odola iibhodi zakho zesekethe eziprintiweyo, ngaba kufuneka uhlawule ngakumbi kwi-silkscreen?Kukho imibuzo ekufuneka uyazi ukuba yintoni i-silkscreen?Kwaye kubaluleke kangakanani i-silkscreen kwibhodi yakho ye-PCB eyenziwe okanye iNdibano yeBhodi yeSekethe eprintiweyo?Ngoku i-ABIS iya kukucacisela.Yintoni i-silkscreen?I-Silkscreen ngumaleko we-inki yokulandela esetyenziselwa ukuchonga amacandelo, ...
- Ibhodi yeSekethe eprintiweyo |Ukucwenga ngomngxuma, umngxuma oyimfama, umngxuma ongcwatywe
Ibhodi yesekethe eprintiweyo yenziwe ngezaleko zeesekethe zefoyile yobhedu, kwaye unxibelelwano phakathi kwamaleko esekethe ahlukeneyo axhomekeke kwezi "vias".Oku kungenxa yokuba ukuveliswa kwebhodi yesekethe yanamhlanje isebenzisa imingxuma egrunjiweyo ukudibanisa iisekethe ezahlukeneyo.Phakathi kweengqimba zeesekethe, kufana nomjelo wokudibanisa weendlela ezininzi zamanzi angaphantsi komhlaba.Abahlobo abadlale ividiyo ethi "UMzalwana uMariya" ...
