Iteyiphu yokugubungelaisetyenziswa ikakhulu kushishino lokufakwa kwecandelo lombane. Isetyenziswe ngokubambisana ne-tape yokuthwala ukugcina nokugcina izixhobo ze-elektroniki ezifana ne-resistors, i-capacitors, i-transistors, i-diodes, njl.
I-tape yokugubungela ngokuqhelekileyo isekelwe kwifilimu ye-polyester okanye i-polypropylene, kwaye idibaniswe okanye ifakwe ngeendlela ezahlukeneyo zokusebenza (i-anti-static layer, i-adhesive layer, njl.). Kwaye itywinwe phezu kwepokotho kwi-tape yokuthwala ukwenza indawo evaliweyo, esetyenziselwa ukukhusela amacandelo e-elektroniki ekungcoleni kunye nomonakalo ngexesha lokuthutha.
Ngethuba lokubekwa kwamacandelo e-elektroniki, i-tape yokugubungela ikhutshwe, kwaye izixhobo zokubeka ngokuzenzekelayo zibeka ngokuchanekileyo amacandelo epokothweni ngokusebenzisa umngxuma we-sprocket we-tape ye-carrier, kwaye emva koko ithatha kwaye ibeke kwibhodi yesekethe edibeneyo (ibhodi ye-PCB) ngokulandelelana.
Ukuhlelwa kweeteyiphu zokugquma
A)Ngobubanzi betape yesigqubuthelo
Ukufanisa ububanzi obuhlukeneyo be-tape ye-carrier carrier, iiteyipu zokugubungela zenziwe ngobubanzi obuhlukeneyo. Ububanzi obuqhelekileyo bu-5.3 mm (5.4 mm), 9.3 mm, 13.3 mm, 21.3 mm, 25.5 mm, 37.5 mm, njl.
B)Ngeempawu zokutywina
Ngokweempawu zokubopha kunye nokuxobula kwiteyiphu yokuthwala, iiteyiphu zokugubungela zinokwahlulwa zibe ziindidi ezintathu:iteyiphu yokuvala i-heat-activated (HAA), i-tape ye-cover-sensitive cover tape (PSA), kunye ne-universal cover tape entsha (UCT).
1. Iteyiphu yekhava efakwe kubushushu (HAA)
Ukutywinwa kwe-tape ye-cover esebenzayo yokushisa kufezekiswa ngokutshisa kunye noxinzelelo oluvela kwibhloko yokutywinwa komatshini wokutywina. Ngelixa i-adhesive ye-melt eshushu inyibilika kwindawo yokutywinwa kwe-tape ye-carrier carrier, i-tape ye-cover ixinzelelwe kwaye itywinwe kwi-tape yokuthwala. Iteyiphu yokugubungela ubushushu ayinayo i-viscosity kwiqondo lobushushu begumbi, kodwa iba incangathi emva kokufudumeza.
2.I-adhesive enoxinzelelo loxinzelelo (PSA)
Ukutywinwa kwe-tape ye-cover-sensitive cover tape kwenziwa ngumatshini wokutywina usebenzisa uxinzelelo oluqhubekayo ngokusebenzisa i-roller yoxinzelelo, ukunyanzelisa i-adhesive-sensitive adhesive on the cover cover to bond to the carrier carrier. Amacala amabini ancamathelayo ancamathelayo etheyiphu yokuvala uxinzelelo ancangathi kwiqondo lobushushu begumbi kwaye anokusetyenziswa ngaphandle kokufudumeza.
3. ITape entsha ye-Universal Cover (UCT)
Amandla e-peeling of the cover tapes kwiimarike ikakhulu kuxhomekeke kumandla okubambelela kwiglue. Nangona kunjalo, xa iglue efanayo isetyenziselwa izinto ezahlukeneyo zomhlaba kwi-tape yokuthwala, amandla okubambelela ayahluka. Amandla okubambelela kwiglue abuye ahluke phantsi kweendawo ezahlukeneyo zokushisa kunye neemeko zokuguga. Ukongezelela, kunokubakho ukungcoliswa kweglue eseleyo ngexesha lokucoca.
Ukusombulula ezi ngxaki zithile, uhlobo olutsha lweteyiphu yokugquma jikelele luye lwaziswa kwimarike. Amandla e-peeling awathembeli kumandla okubambelela kwiglue. Endaweni yoko, kukho iigrooves ezimbini ezinzulu ezisikwe kwifilimu esisiseko yeteyiphu yokugubungela ngokulungiswa komatshini.
Xa i-peeling, i-tape ye-cover ikrazula kunye ne-grooves, kwaye i-peelling force ixhomekeke kwi-glue yamandla enamathelayo, echaphazelekayo kuphela ngobunzulu be-grooves kunye namandla omatshini wefilimu, ukwenzela ukuba kuqinisekiswe ukuzinza kwamandla okugcoba. Ukongezelela, ngenxa yokuba kuphela indawo ephakathi kwekhava yekhava ekhutshwe ngexesha lokuhluma, ngelixa omabini amacala ekhava ehlala ebambelele kumgca wokutywina we-carrier tape, iphinda inciphise ukungcoliswa kweglue eseleyo kunye ne-debris kwizixhobo kunye namacandelo.
