Kwiminyaka yakutshanje, ii-PCBs eziguquguqukayo ziye zaduma ngenxa yendibaniselwano yazo ekhethekileyo yokuguquguquka kunye nokuqina.Olu hlobo lwebhodi yesekethe luvumela abaqulunqi ukuba benze izisombululo ezintsha kunye nezonga indawo, ngakumbi kwizicelo apho iibhodi eziqinileyo zendabuko azikwazi ukuhlangabezana neemfuno.Ngelixa ii-PCB eziguquguqukayo ezilukhuni zibonelela ngoluhlu olunokwenzeka loyilo, kusekho imida ethile ekufuneka iqwalaselwe, ngakumbi ngokumalunga ne-bend radii.
Iradiyasi egobileyo yePCB yeyona radiyasi incinci apho ibhodi inokugotshwa ngokukhuselekileyo ngaphandle kokwenza umonakalo kwimikhondo okanye amacandelo.Kwiibhodi ze-rigid-flex, i-radius yokugoba yiparameter ephambili echaphazela ngokuthe ngqo ukusebenza ngokubanzi kunye nokuthembeka kwebhodi yesiphaluka.
Xa uyila i-PCB eqinile-eguquguqukayo, kufuneka uqonde imida ebekwe yiradiyasi yokugoba.Ukogqitha iradiyasi ecetyisiweyo yokugoba kunokubangela iingxaki ezinjengomkhondo we-delamination, ukwaphuka, okanye ukungaphumeleli kwecandelo.Ngoko ke, lo mbandela kufuneka uqwalaselwe ngononophelo ngexesha lesigaba soyilo ukuqinisekisa ukusebenza ngokufanelekileyo kunye nokuphila ixesha elide kwebhodi.
Umda wokugoba weradiyasi yeePCB eziguquguqukayo zixhomekeke kwizinto ezahlukeneyo, kubandakanywa izinto zokwakha, inani leeleya, kunye nobukhulu bebhodi ngokubanzi.Masingene nzulu kwinto nganye ukuze siqonde ngcono ifuthe labo:
1. Izinto zokwakha:Ukukhethwa kwezinto eziphathekayo, ezifana nesiseko kunye nezinto eziguquguqukayo ezisetyenzisiweyo, zichaphazela ngokuthe ngqo umda we-radius bend.Izinto ezahlukeneyo zineempawu ezahlukeneyo zokuguquguquka, ezichaphazela i-radius ye-bend encinci.Ngokomzekelo, i-polyimide lukhetho oluqhelekileyo kwiindawo eziguquguqukayo ngenxa yokuguquguquka okugqwesileyo kunye nokumelana nokushisa okuphezulu.Nangona kunjalo, ukhetho lwezinto eziphathekayo kufuneka lulungelelaniswe ngokucokisekileyo, njengoko ukusebenzisa izinto eziguquguqukayo kakhulu kunokubangela ukugoba ngokugqithiseleyo kwaye mhlawumbi umonakalo kwibhodi.
2. Inani leeleya:Inani leeleya zebhodi e-rigid-flex iya kuchaphazela umda we-radius egoba.Ngokubanzi, okukhona ibhodi inamaleko, kokukhona iradiyasi yokugoba kufuneka ibe nkulu.Oku kungenxa yokuba umaleko owongezelelweyo wazisa ukuqina ngakumbi, okwenza ibhodi ibe nzima ngakumbi ukugoba ngaphandle kokutsala umkhondo okanye kubangela ezinye iingxaki zoomatshini.Abaqulunqi kufuneka baqwalasele ngokucophelela inani leengqimba ezifunekayo kwisicelo esithile kwaye balungise i-radius bend ngokufanelekileyo.
3. Ubunzima bubonke bepleyiti:Ubunzima bepleyiti nabo budlala indima ebalulekileyo ekunqumeni umda we-bend radius.Iipleyiti ezityebileyo zikholisa ukuba neradiya enkulu egobileyo kuneepleyiti ezibhityileyo.Njengoko ubukhulu bebhodi bukhula, izinto ziba nzima, zifuna iradiyasi enkulu yokugoba ukuphepha nawuphi na umonakalo onokuthi ubekho.
Xa kuqwalaselwa le miba kunye nokumisela imida eguquguqukayo yee-PCB eziguquguqukayo, kukwabalulekile ukuba kuqwalaselwe naziphi na izinto zangaphandle ezinokuchaphazela ukusebenza kwebhodi.Umzekelo, iimfuno ezithile zesicelo ezifana nokuguquguquka okufunekayo okanye ukuvezwa kwebhodi yesekethe kumaqondo obushushu aphezulu kunokuchaphazela ngakumbi imida yeradiyasi egobileyo.
Ukuqinisekisa ukugoba i-radii efanelekileyo kwiibhodi eziguquguqukayo, kuyacetyiswa ukuba usebenze ngokusondeleyo nabavelisi abanamava kunye nabaqulunqi abanolwazi olubanzi kunye nobuchule kulo mmandla.Banokubonelela ngengqiqo ebalulekileyo, isikhokelo kunye nenkxaso kuyo yonke inkqubo yoyilo kunye nemveliso.Ukongeza, ukusebenzisa izixhobo zokulinganisa eziphambili kunye nokuqhuba uvavanyo olucokisekileyo kunokunceda ukuqinisekisa iradiyasi ekhethiweyo kunye nokuqinisekisa ukuthembeka kwebhodi kunye nokuphila ixesha elide.
Isishwankathelo, nangona ii-PCB eziguquguqukayo zibonelela ngoluhlu olubanzi lwamathuba oyilo, imida yeradiyasi egobayo kufuneka iqwalaselwe.Ukukhethwa kwezinto zokwakha, inani leengqimba kunye nobukhulu bepaneli ngokubanzi buchaphazela ngokuthe ngqo umda we-radius bend.Ngokulungelelanisa ngononophelo le miba kunye nokuqwalasela iimfuno ezithile zesicelo, abaqulunqi banokudala ii-PCB eziqinileyo nezithembekileyo eziguquguqukayo ezihlangabezana nokuguquguquka okufunekayo ngelixa uphepha nayiphi na imiba enokubakho enxulumene nokugoba.Ukusebenza kunye neengcali ezinamava kunye nokuxhasa izixhobo zokulinganisa eziphambili kunokuququzelela kakhulu impumelelo yoyilo lwePCB elukhuni.
