Yintoni umbala webhodi ye-PCB, njengoko igama libonisa, xa ufumana ibhodi ye-PCB, eyona nto intuitive ukubona umbala weoli ebhodini, oko kukuthi, sibhekisela ngokubanzi kumbala webhodi ye-PCB, imibala eqhelekileyo ziluhlaza, zibhlowu, zibomvu namnyama njalo njalo.Aba balandelayo beXiaobian babelana ngokuqonda kwabo ngemibala eyahlukeneyo.
- I-1, i-inki eluhlaza yiyona nto isetyenziswa kakhulu, isiganeko eside kunazo zonke zembali, kwaye kwimarike yangoku iyeyona inexabiso eliphantsi, ngoko uhlaza lusetyenziswa linani elikhulu labavelisi njengowona mbala uphambili weemveliso zabo.
- I-2, phantsi kweemeko eziqhelekileyo, yonke imveliso yebhodi ye-PCB kwinkqubo yokuvelisa kukuba ihambe ngebhodi kunye nenkqubo ye-SMT, ebhodini, kukho iinkqubo ezininzi kufuneka zidlule kwigumbi lokukhanya eliphuzi, kuba umphumo wohlaza kwindawo ephuzi. igumbi elikhanyayo lingcono kuneminye imibala, kodwa oku akusona sizathu siphambili.Xa iikhomponenti ze-SMT welding, i-PCB ukuya kwi-solder paste kunye nokuncamathisela kunye nenkqubo yesibane yokugqibela ye-AOI yokutshekisha, ezi nkqubo kufuneka zifunde ukulinganisa indawo yokubona, umbala ongasemva oluhlaza kwisiphumo sokuchongwa kwesixhobo kungcono.
- 3.Imibala yePCB eqhelekileyo ibomvu, tyheli, eluhlaza, eluhlaza okwesibhakabhaka nomnyama.Nangona kunjalo, ngenxa yenkqubo yemveliso kunye nezinye iingxaki, inkqubo yokuhlolwa komgangatho wemigca emininzi kusafuneka ixhomekeke kubasebenzi ukuze babone kwaye bachonge ngeso lenyama (kakade, uninzi lokusetyenziswa kwangoku kweteknoloji yokuvavanya inaliti).Kwimeko yokukhanya okunamandla, amehlo ahlala ejonge ebhodini, eyinkqubo yokusebenza kaLiu endala kakhulu, xa sithetha, uhlaza yeyona nto inobungozi emehlweni, ngoko ke uninzi lwabavelisi kwimarike basebenzisa iPCB eluhlaza.
- I-4, umgaqo oluhlaza okwesibhakabhaka nomnyama kukuba zixutywe kunye ne-cobalt kunye ne-carbon element yesibane, kunye ne-conductivity ethile yombane, kwimeko yamandla kunokwenzeka ukuba iingxaki ze-short-circuit, kunye ne-PCB eluhlaza ihambelana nokusingqongileyo, xa isetyenziselwa indawo yobushushu obuphezulu, ngokuqhelekileyo ayiyi kukhulula iigesi ezinetyhefu.
- Kwaye kukho inani elincinci labavelisi kwiimarike baya kusebenzisa ibhodi yePCB emnyama, izizathu eziphambili apho uXiaobian ukholelwa ukuba kukho izizathu ezibini: okokuqala, kubonakala kuphezulu, kwaye ibhodi emnyama ayilula ukubona i-wiring. , ezisa ubunzima obuthile kwibhodi yokukopa.Oko uXiaobian wakufundayo kukuba uninzi lweebhodi ezifakwe kwi-Android ngoku zi-PCBS ezimnyama.
- I-5, malunga nexesha eliphakathi kunye nasekupheleni kwenkulungwane edlulileyo, ishishini liye laqala ukunikela ingqalelo kumbala webhodi ye-PCB, ngokukodwa ngenxa yokuba iintlobo ezininzi zebhodi eziphakamileyo zabenzi bomgca wokuqala ziye zamkela ibhodi yombala we-PCB eluhlaza, ngoko ke. abantu ngokucothayo bacinga ukuba umbala PCB eluhlaza kufuneka high-isiphelo.
