Itheyiphu yokumbozaisetshenziswa kakhulu embonini yokubeka izingxenye ze-elekthronikhi. Isetshenziswa ngokuhambisana netheyiphu yenkampani yenethiwekhi ukuze iphathe futhi igcine izingxenye ze-elekthronikhi ezifana nama-resistors, ama-capacitor, ama-transistors, ama-diode, njll. emaphaketheni we-carrier tape.
Itheyiphu yekhava ngokuvamile isekelwe ku-polyester noma ifilimu ye-polypropylene, futhi ihlanganiswe noma ihlanganiswe ngezendlalelo ezihlukene zokusebenza (i-anti-static layer, i-adhesive layer, njll.). Futhi ivalwe phezu kwephaketheni ku-tape yenethiwekhi ukuze kwakhiwe indawo evaliwe, esetshenziselwa ukuvikela izingxenye ze-elekthronikhi ekungcoleni nasekulimaleni ngesikhathi sokuthutha.
Ngesikhathi sokubekwa kwezingxenye ze-elekthronikhi, ikhava yekhava iyahlutshiwe, futhi imishini yokubeka ngokuzenzakalelayo ibeka ngokunembile izingxenye ephaketheni ngokusebenzisa imbobo ye-sprocket ye-tape ye-carrier, bese ithatha futhi ibekwe ebhodini lesifunda elihlanganisiwe (PCB board) ngokulandelana.
Ukuhlukaniswa kwamakhava amakhava
A)Ngobubanzi bekhava yekhava
Ukufanisa ububanzi obuhlukene be-tape yenkampani yenethiwekhi, amateyipu ekhava enziwe ngobubanzi obuhlukene. Ububanzi obujwayelekile buyi-5.3 mm (5.4 mm), 9.3 mm, 13.3 mm, 21.3 mm, 25.5 mm, 37.5 mm, njll.
B) Ngezimpawu zokuvala
Ngokwezici zokubopha nokucwecwa kwetheyiphu yenethiwekhi, amateyipu ekhava angahlukaniswa abe yizinhlobo ezintathu:itheyiphu yekhava eyenziwe yasebenza ukushisa (HAA), ikhava yekhava ezwela ukucindezela (PSA), kanye nekhava yekhava entsha yendawo yonke (UCT).
1. Itheyiphu yekhava eyenziwe yasebenza ukushisa (HAA)
Ukuvalwa kwetheyiphu yekhava eyenziwe ngokushisa kufinyelelwa ngokushisa nokucindezela okuvela ebhodini lokuvala lomshini wokuvala. Ngenkathi i-adhesive encibilikayo eshisayo incibilika endaweni yokuvala ye-tape yenkampani yenethiwekhi, ikhava yekhava iyacindezelwa futhi ivalwe ku-tape yenethiwekhi. Itheyiphu yekhava eyenziwe yasebenza ngokushisa ayinakho i-viscosity ekamelweni lokushisa, kodwa iyanamathela ngemva kokushisa.
2.I-adhesive ebucayi ngomfutho (PSA)
Ukuvalwa kwetheyiphu yekhava ezwela ukucindezela kwenziwa umshini wokuvala osebenzisa ingcindezi eqhubekayo ngokusebenzisa i-roller yokucindezela, okuphoqa ukunamathela okuzwela ukucindezela kukhava yekhava ukuze kuhlanganiswe itheyipu yenethiwekhi. Unqenqema olunamathelisa lwezinhlangothi ezimbili lwekhava yekhava ezwela ukucindezela lunamathela kuzinga lokushisa legumbi futhi lungasetshenziswa ngaphandle kokushisisa.
3. Itheyiphu entsha ye-Universal Cover (UCT)
Amandla okuxebuka amateyipu ekhava emakethe ngokuyinhloko ancike emandleni okunamathela weglue. Kodwa-ke, lapho i-glue efanayo isetshenziswa ngezinto ezingaphezulu ezihlukile ku-tape yenethiwekhi, amandla okunamathela ayahlukahluka. Amandla okunamathela eglue nawo ayahlukahluka ngaphansi kwezindawo ezihlukene zokushisa nezimo zokuguga. Ngaphezu kwalokho, kungase kube nokungcoliswa kweglue esele ngesikhathi sokucwecwa.
Ukuxazulula lezi zinkinga ezithile, uhlobo olusha lwekhava ye-universal tape yethulwe emakethe. Amandla okucwecwa awancikile emandleni okunamathela eglue. Esikhundleni salokho, kunemigodi emibili ejulile esikwe efilimini yesisekelo sekhava yekhava ngokucubungula okunembile kwemishini.
Lapho ucwecwa, ikhava yekhava idabula eduze kwama-grooves, futhi amandla okucwenga azimele ngaphandle kwamandla okunamathela weglue, okuthinteka kuphela ukujula kwama-grooves namandla omshini wefilimu, ukuze kuqinisekiswe ukuzinza kwamandla okucwenga. Ngaphezu kwalokho, ngenxa yokuthi ingxenye ephakathi kuphela yekhava yekhava ihlutshiwe ngesikhathi sokucwecwa, kuyilapho izinhlangothi zombili zekhava yekhava zihlala zinamathele emgqeni wokuvala we-tape othwala, futhi kunciphisa ukungcoliswa kwe-glue esele kanye nemfucumfucu kumishini kanye nezingxenye.
