Kule mihla, izixhobo zombane kumashishini ahlukeneyo yeyona njongo iphambili yokusukela iimveliso ezigqwesileyo, ezincinci kodwa ezisebenza ngokupheleleyo. Ubunzima bokukhanya kunye nokunyamezela indawo ephezuluI-Rigid-Flex PCBzibenze zilungele amashishini ahlukeneyo, kubandakanywa i-aerospace, izixhobo zonyango, izixhobo zokulawula i-industrial, kunye ne-electronics yabathengi. Nangona kunjalo, uyilo kunye nokuveliswa kwe-PCBS eqinile-eguqukayo ineemfuno zemathiriyeli ezithile kunye nokuqwalaselwa kokusebenza, ngakumbi xa kufikwa kwiingubo ezihambelanayo. Kweli phepha, iimfuno zeengubo ezihambelanayo kwiI-Rigid-FlexUyilo PCB kuxoxwa, kunye neziphumo zabo kwiimfuno PCB eziphathekayo, inkqubo yoyilo kunye nokusebenza iyonke kuxoxwe.
PCB Material iimfuno
Ukhetho lwezixhobo lubalulekile kuyilo lweRigid-Flex PCB. Izinto eziphathekayo akufanele zixhase kuphela ukusebenza kombane kodwa ziphinde zimelane noxinzelelo lomatshini kunye nezinto ezisingqongileyo. Izinto eziqhelekileyo ezisetyenziswa kwiRigid-Flex PCB ziquka:
- Polyimide (PI): Eyaziwa ngokuba yi-thermal stability egqwesileyo kunye nokuguquguquka, i-polyimide isoloko isetyenziselwa amacandelo aguquguqukayo e-Rigid-Flex PCBs.
- FR-4: Isixhobo esisetyenziswa ngokubanzi kumacandelo aqinileyo, i-FR-4 inika ukufakwa kakuhle kombane kunye namandla omatshini.
- Ubhedu: Kubalulekile kwiindlela zokuqhuba, ubhedu lusetyenziselwa ubuninzi obuhlukeneyo ngokuxhomekeke kwiimfuno zoyilo.
Xa usebenzisa i-coating conformal, kubalulekile ukuqwalasela ukuhambelana kwezi zinto kunye nezinto zokugqoka. Ukugquma kufuneka kuhambelane kakuhle ne-substrate kwaye ingachaphazeli kakubi iipropati zombane zePCB.
Ukugqunywa kwe Coating Conformal
Ukwambathisa ngokusesikweni ngumaleko okhuselayo osetyenziswa kwiiPCBs ukuzikhusela kwizinto ezisingqongileyo ezifana nokufuma, uthuli, iikhemikhali, kunye nokuguquguquka kobushushu. Kumxholo we-Rigid-Flex PCBs, ukugqunywa kwe-conformal coating kubaluleke kakhulu ngenxa yoyilo olulodwa oludibanisa izinto eziqinileyo neziguquguqukayo.
Iingqwalaselo eziPhambili kuMgqubuthela woKugqunywa ngokusesikweni
Isicelo esifanayo: Ukugqoka kufuneka kusetyenziswe ngokufanayo kuzo zombini iindawo eziqinileyo kunye neziguquguqukayo ukuze kuqinisekiswe ukukhuselwa okuhambelanayo. Ukhuselo olungalinganiyo lunokukhokelela kubuthathaka kwiindawo ezithile, okunokuthi kubeke esichengeni ukusebenza kwePCB.
Ukulawula ukutyeba: Ubukhulu bengubo ehambelanayo bubalulekile. Umaleko oshinyene kakhulu unokuchaphazela ukuguquguquka kwePCB, ngelixa umaleko obhityileyo kakhulu unokunganikeli ukhuseleko olululo. Abavelisi kufuneka balawule ngononophelo inkqubo yesicelo ukufezekisa ubukhulu obufunwayo.
Ukuba bhetyebhetye: Ingubo ehambelanayo kufuneka igcine ingqibelelo yayo ngexesha lokugoba kunye nokuguqulwa kwe-PCB. Oku kufuna ukukhetha iingubo ezilungiselelwe ngokukodwa izicelo eziguquguqukayo, ziqinisekisa ukuba ziyakwazi ukumelana noxinzelelo lomatshini ngaphandle kokuqhekeka okanye ukuxubha.
IiMfuno zeNkqubo ye-PCB eRigid-Flex
Inkqubo yokwenziwa kweeRigid-Flex PCBs ibandakanya amanyathelo aliqela, ngalinye lineseti yalo yeemfuno. Ezi ziquka:
Ukupakishwa kweLayer: Uyilo kufuneka luphendule ukupakishwa kweeleyile eziqinileyo kunye neziguquguqukayo, ukuqinisekisa ukulungelelaniswa okufanelekileyo kunye nokubambelela phakathi kwezinto ezahlukeneyo.
Ukuqhotyoshwa kunye nokuGwatywa: Ukuchaneka ngundoqo kwiinkqubo ze-etching kunye ne-drilling ukudala i-circuitry efunekayo. Inkqubo kufuneka ilawulwe ngononophelo ukuphepha ukonakalisa amacandelo aguquguqukayo.
Isicelo sokugquma: Ukusetyenziswa kwengubo ehambelanayo kufuneka kuhlanganiswe kwinkqubo yokuvelisa. Ubuchwephesha obufana nokutshiza, ukudipha, okanye ukugquma okukhethiweyo kungasetyenziswa, kuxhomekeke kuyilo kunye neemfuno zezinto eziphathekayo.
Ukunyanga: Ukunyangwa ngokufanelekileyo kwengubo ehambelanayo kubalulekile ukufezekisa izinto ezifunekayo zokukhusela. Inkqubo yokunyanga kufuneka iphuculwe ukuqinisekisa ukuba i-coating ibambelela kakuhle kwi-substrate ngaphandle kokuchaphazela ukuguquguquka kwe-PCB.
Ukusebenza kwe-PCB eRigid-Flex
Ukusebenza kweRigid-Flex PCBs kuphenjelelwa zizinto ezahlukeneyo, kubandakanya ukukhethwa kwezinto, ukuntsonkotha koyilo, kunye nokusebenza kokutyatyekwa okuhambelanayo. I-Rigid-Flex PCB eyilwe kakuhle ene-conformal coating efanelekileyo inokubonelela ngeenzuzo ezininzi:
- Ukomelezwa koKuhlala ixesha elide: Ukwambathisa ngokusesikweni ukhusela ngokuchasene noxinzelelo lokusingqongileyo, ukwandisa ubomi bePCB.
- Ukuphucula ukuthembeka: Ngokukhusela i-circuitry, i-coating conformal iphakamisa ukuthembeka okupheleleyo kwesixhobo, ukunciphisa umngcipheko wokungaphumeleli kwizicelo ezibalulekileyo.
- Uyilo lokuguquguquka: Ukudityaniswa kwezinto eziqinileyo kunye neziguquguqukayo kuvumela ukuyila kwezinto ezintsha ezinokuziqhelanisa neemeko ezahlukeneyo zeefom, okwenza iiRigid-Flex PCBs zilungele uluhlu olubanzi lwezicelo.
