Kwihlabathi elivela ngokukhawuleza le-electronics, imfuno yokusebenza okuphezulu, i-compact, kunye nezinto ezithembekileyo zihlala zikhula. Elinye icandelo eliye lafumana i-traction ebalulekileyo yi-multi-layer flexible printed circuit (FPC). Eli nqaku liphonononga ubucukubhede bokwenziwa kwe-FPC yemigangatho emininzi, kugxininise kwiinkcukacha ezinjengokugqitywa komphezulu, ubukhulu bebhodi, kunye nenkqubo yokuvelisa, ngakumbi kumxholo wovavanyo lweentambo zesikrini.
Ukuqonda i-FPC yoMaleko amaninzi
Ii-FPC ezinamanqwanqwa amaninzi ziyimfuneko kwizixhobo zombane zanamhlanje, zibonelela ngesisombululo esikhaphukhaphu nesiguquguqukayo soyilo lwesekethe enzima. Ngokungafaniyo neePCB zemveli eziqinileyo, ii-FPC ezinomaleko amaninzi zinokugoba kwaye zijije, zizenze zilungele usetyenziso kwii-smartphones, izinto ezinxitywayo, kunye nezinye izixhobo ezixineneyo. Ukukwazi ukwenza ezi mveliso kuvumela abavelisi ukuba bahlangabezane neemfuno ezithile, baqinisekise ukusebenza kakuhle kwizicelo ezahlukeneyo.
Iimveliso ezenzelwe wena: Ukulungelelanisa kwiiMfuno eziKhethekileyo
Ukwenza ngokwezifiso kusembindini wokwenziwa kweFPC enemigangatho emininzi. Iprojekthi nganye inokuba neemfuno ezizodwa ezisekelwe kwisicelo, ezifana nobukhulu, imilo, kunye nokusebenza kombane. Abavelisi basebenzisana ngokusondeleyo nabathengi ukuphuhlisa izisombululo ezilungiselelweyo ezihlangabezana neenkcukacha zabo. Le ntsebenziswano ihlala ibandakanya iingxoxo ezineenkcukacha malunga nokusetyenziswa okucetywayo kwe-FPC, imeko-bume eza kusebenza kuyo, kunye nayo nayiphi na imigangatho yolawulo ethile ekufuneka ithotyelwe.
Ukugqitywa komphezulu: Ukubaluleka kwe-ENIG 2uin
Omnye wemiba ebalulekileyo yokwenziwa kwe-FPC enemigangatho emininzi kukugqiba komphezulu. Ukhetho oluqhelekileyo lwee-FPC ezikumgangatho ophezulu kukugqiba i-Electroless Nickel Immersion Gold (ENIG), ngokukodwa kubukhulu be-2uin. Olu kugqiba umphezulu lubonelela ngeenzuzo ezininzi:
Ukuxhathisa ukonakala:I-ENIG inika ukhuseleko olugqwesileyo kwi-oxidation kunye ne-corrosion, iqinisekisa ixesha elide lesekethe.
I-Solderability:Umaleko wegolide uphucula ukuthengiselana, okwenza kube lula ukuqhoboshela amacandelo ngexesha lokuhlanganisa.
Ukucaba:Ukugqitywa kwe-ENIG kwaziwa ngokutyaba kwazo, okubalulekileyo ekuqinisekiseni uqhagamshelo oluthembekileyo kuyilo lwemigangatho emininzi.
Ngokukhetha umphezulu we-ENIG 2uin ukugqiba, abavelisi banokuqinisekisa ukuba ii-FPC zabo ezinoluhlu oluninzi zigcina ukusebenza okuphezulu kunye nokuthembeka kumjikelo wabo wobomi.
Ukutyeba kwebhodi: Ukubaluleka kwe-0.3mm
Ubukhulu bebhodi ngomnye umba obalulekileyo kwimveliso yeFPC enemigangatho emininzi. Inkcazo eqhelekileyo bubunzima obuyi-0.3mm, obubetha ibhalansi phakathi kokuguquguquka kunye nokuqina. Obu bukhulu buvumela uyilo oluntsonkothileyo ngelixa ugcina imfezeko yesakhiwo efunekayo kwizicelo ezahlukeneyo.
Iibhodi ezibhityileyo ziluncedo ngakumbi kwizixhobo ezixineneyo apho indawo ikwiprimiyamu. Nangona kunjalo, ukufezekisa ubukhulu obufanelekileyo kufuna ukuchaneka kwinkqubo yokuvelisa ukuqinisekisa ukuba i-FPC inokumelana noxinzelelo lomatshini ngaphandle kokunciphisa ukusebenza.
Inkqubo yokuVelisa: Ukuchaneka kunye noLawulo loMgangatho
Inkqubo yokwenziwa kwee-FPC ezinomaleko amaninzi ibandakanya amanqanaba amaninzi, ngalinye lifuna ingqwalasela ecokisekileyo kwiinkcukacha. Nantsi inkcazo emfutshane yamanyathelo aphambili abandakanyekayo:
Uyilo kunye nePrototyping: Inkqubo iqala ngesigaba soyilo, apho iinjineli zenza i-schematics kunye noyilo oluneenkcukacha. Iprototyping ivumela uvavanyo kunye nokuqinisekiswa koyilo ngaphambi kokuveliswa kobuninzi.
Ukukhethwa kwezinto:Ukukhetha imathiriyeli efanelekileyo kubalulekile. Iifilimu zePolyimide ezikumgangatho ophezulu okanye iifilimu zepolyester zihlala zisetyenziselwa izinto ezibalaseleyo zobushushu kunye nombane.
Ukupakishwa koMaleko:Kwi-FPCs zomaleko amaninzi, iileya zipakishwe kwaye zilungelelaniswe ngokuchanekileyo. Eli nyathelo libalulekile ekuqinisekiseni ukuba uqhagamshelo lombane phakathi kweeleya luthembekile.
Ukuqhotyoshwa kunye noKutyalwa:Iipateni zesekethe zenziwe nge-etching, ilandelwa yi-plating ukwakha ubukhulu obuyimfuneko bobhedu.
Ukugqitywa komphezulu:Emva kwe-etching, umgangatho we-ENIG ugqityiwe, unikezela ukhuseleko oluyimfuneko kunye nokuthengiswa.
Uvavanyo:Uvavanyo olungqongqo lwenziwa ukuqinisekisa ukuba i-FPC ihlangabezana nazo zonke iinkcukacha. Oku kubandakanya uvavanyo lombane, iimvavanyo zoxinzelelo koomatshini, kunye novavanyo lokuhamba ngebhayisikile eshushu.
Ukuhlolwa kokuGqibela kunye noLawulo loMgangatho: Ngaphambi kokuthunyelwa, i-FPC nganye ihlolwa okokugqibela ukuze iqinisekise ukuba ihlangabezana nemigangatho efunekayo. Ukulawulwa komgangatho kubaluleke kakhulu kwinkqubo yokuvelisa ukukhusela iziphene kunye nokuqinisekisa ukuthembeka.
Vavanya iSkrini seSiseko seNdawo yeCable Application
Olunye usetyenziso olubalulekileyo lwe-FPCs zomaleko oluninzi lukwindawo yovavanyo lwentambo yesikrini. Ezi ntambo ziyimfuneko ekudibaniseni amacandelo ahlukeneyo kwiindawo zokuvavanya, ukuqinisekisa ukuba iimpawu zihanjiswa ngokuchanekileyo nangokufanelekileyo. Ukuguquguquka kunye nokubumbana kwee-FPC ezinomaleko amaninzi kuzenza zilungele esi sicelo, zivumela ukuba kube lula ukuhamba kunye nokufakwa kwiindawo ezixineneyo.
Kuvavanyo lwezicelo zentambo yesikrini, ukuthembeka kweFPC kubaluleke kakhulu. Nakuphi na ukungaphumeleli kwintambo kunokukhokelela kwiziphumo zovavanyo ezingachanekanga, nto leyo eyenza ukuba kubaluleke kakhulu ukuba abavelisi babambelele kumanyathelo okulawula umgangatho angqongqo kuyo yonke inkqubo yokuvelisa.
