3 Umaleko Pcb inkqubo unyango umphezulu: ukuntywiliselwa igolide kunye OSP

Xa ukhetha inkqubo yonyango lomphezulu (njengokuntywiliselwa kwegolide, i-OSP, njl.) kwi-PCB yakho ye-3-layer, inokuba ngumsebenzi onzima.Kuba zininzi iindlela onokukhetha kuzo, kubalulekile ukukhetha eyona nkqubo ifanelekileyo yonyango lomphezulu ukuhlangabezana neemfuno zakho ezithile.Kule posi yebhlog, siza kuxoxa ngendlela yokukhetha olona nyango luphezulu lwe-PCB yakho enemigangatho emi-3, siqaqambisa ubuchule be-Capel, inkampani eyaziwa ngolawulo lwayo olukumgangatho ophezulu kunye neenkqubo zokwenziwa kwe-PCB ephucukileyo.

I-Capel idume ngee-PCB zayo eziqinileyo, ii-PCB eziguquguqukayo kunye ne-HDI PCBs.Ngezatifikethi ezinelungelo elilodwa lomenzi kunye noluhlu olubanzi lweenkqubo zokwenziwa kwe-PCB eziphucukileyo, iCapel izimise njengenkokeli yoshishino.Ngoku makhe sijonge ngakumbi kwizinto ekufuneka ziqwalaselwe xa ukhetha umphezulu ogqityiweyo we-PCB enomaleko-3.

1. Isicelo kunye nokusingqongileyo

Okokuqala, kubalulekile ukumisela isicelo kunye nokusingqongileyo kwe-PCB yomaleko-3.Iinkqubo ezahlukeneyo zonyango lomhlaba zibonelela ngamanqanaba ahlukeneyo okhuseleko ngokuchasene nokubola, i-oxidation kunye nezinye izinto zokusingqongileyo.Umzekelo, ukuba i-PCB yakho iya kuboniswa kwiimeko ezinzima, ezinje ngokufuma okuphezulu okanye amaqondo obushushu agqithisileyo, kuyacetyiswa ukuba ukhethe inkqubo yonyango engaphezulu ebonelela ngokhuseleko olongeziweyo, olufana nokuntywiliselwa kwegolide.

2. Iindleko kunye nexesha lokuhambisa

Enye inkalo ebalulekileyo ekufuneka iqwalaselwe ziindleko kunye nexesha lokukhokela elihambelana neenkqubo ezahlukeneyo zonyango lomphezulu.Iindleko zezinto eziphathekayo, iimfuno zabasebenzi kunye nexesha lokuvelisa ngokubanzi liyahluka kwinkqubo nganye.Le miba kufuneka ivavanywe ngokuthelekisa uhlahlo lwabiwo-mali lwakho kunye nexesha leprojekthi yakho ukuze wenze isigqibo esinolwazi.Ubuchwephesha beCapel kwiinkqubo zokuvelisa eziphucukileyo buqinisekisa izisombululo ezingabizi kakhulu kwaye kwangexesha kwiimfuno zakho zokulungiselela umphezulu wePCB.

3. Ukuthotyelwa kweRoHS

Ukuthotyelwa kwe-RoHS (Uthintelo lwezinto ezinobungozi) ngumba ophambili, ngakumbi ukuba imveliso yakho yeyemarike yaseYurophu.Unyango oluthile lomphezulu lunokuthi luqulathe izinto eziyingozi ezingaphaya kwemida ye-RoHS.Kubalulekile ukukhetha inkqubo yonyango yomhlaba ehambelana nemigaqo ye-RoHS.Ukuzinikela kukaCapel kulawulo lomgangatho kuqinisekisa ukuba iinkqubo zonyango lwayo olungaphezulu ziyahambelana ne-RoHS, kukunika uxolo lwengqondo xa kufikwa ekuthotyelweni.

4. Solderability kunye Wire Bonding

I-solderability kunye neempawu ze-wire bonding ze-PCB yingqwalasela ebalulekileyo.Inkqubo yonyango yomphezulu kufuneka iqinisekise i-solderability efanelekileyo, okubangela ukunamathela ngokufanelekileyo kwi-solder ngexesha lokuhlanganisa.Ukongeza, ukuba uyilo lwePCB yakho lubandakanya ukudityaniswa kocingo, inkqubo yonyango yomphezulu kufuneka iphucule ukuthembeka kweebhondi zocingo.I-OSP (i-Organic Solderability Preservative) lukhetho oludumileyo ngenxa yokuthengiswa kwayo okugqwesileyo kunye nokuhambelana kocingo.

5. Ingcebiso nenkxaso yeengcali

Ukukhetha inkqubo elungileyo yonyango lomphezulu kwi-PCB yakho yomaleko-3 kunokuba nzima, ngakumbi ukuba umtsha kwimveliso yePCB.Ukufuna iingcebiso zeengcali kunye nenkxaso kwinkampani ethembekileyo efana neCapel inokwenza inkqubo yokwenza izigqibo ibe lula.Iqela elinamava laseCapel linokukukhokela kwinkqubo yokhetho kwaye licebise eyona nkqubo ifanelekileyo yonyango yomhlaba ngokusekelwe kwiimfuno zakho ezithile.

Isishwankathelo, ukukhetha olona nyango lufanelekileyo lomphezulu lwe-PCB yakho ene-3-layer ibaluleke kakhulu ekusebenzeni kakuhle kunye nobomi obude.Izinto ezifana nesicelo kunye nokusingqongileyo, iindleko kunye nexesha lokukhokela, ukuthotyelwa kwe-RoHS, ukuthengiselana kunye nokudibanisa ucingo kufuneka kuhlolwe ngokucophelela.Ulawulo lomgangatho weCapel, iziqinisekiso ezinelungelo elilodwa lomenzi wechiza kunye neenkqubo zokwenziwa kwe-PCB eziphucukileyo ziyenza ikwazi ukuhlangabezana neemfuno zakho zokulungisa umphezulu.Qhagamshelana neengcali zeCapel kwaye uxhamle kulwazi lwabo olubanzi lweshishini kunye namava.Gcina ukhumbule ukuba iinkqubo zonyango ezikhethiweyo ngokucokisekileyo zinokuchaphazela kakhulu ukusebenza kunye nokuqina kwe-PCB ye-3-layer.
