Itheyiphu ye-PTFE yokushisa ephezulu ingaqhekeka noma iphuke ngaphansi kwezimo zokugoba nokuvula okuphindaphindiwe. Lesi sihloko sichaza ukuthi ungakuvimbela kanjani lokhu ngokukhetha okufanele kwe-substrate (i-fiber yengilazi iqiniswe), ukujiya okuphezulu (0.18mm njengokujwayelekile), ukukhetha kwe-adhesive ye-silicone, nezindlela zokufaka ezifanele.

Ukukhethwa kwephepha lokukhishwa noma i-substrate yefilimu kanye ne-ejenti yokukhulula kuthinta ngokuqondile ukuqina kwesitoreji nokusebenza kokuxebuka kwetheyiphu ye-PTFE yokushisa okuphezulu. Lesi sihloko siqhathanisa i-PET vs. kraft paper substrates kanye ne-silicone ngokumelene nama-ejenti okukhululwa e-fluorinated, incoma inhlanganisela efanele yokuxebuka kwezinsalela eziyiziro nokuthembeka kwesikhathi eside.

Amateyipu e-PTFE okushisa okuphezulu asetshenziswa kakhulu ekufakeni ugesi, kodwa izimo ze-high-frequency kanye ne-high-voltage zibeka izingozi eziyingqayizivele: ukuphuka kukagesi, ukukhipha ingxenye, ukuguga okushisayo, ukulahlekelwa kwesignali ye-high-frequency, kanye nokuzwela kwemvelo. Lesi sihloko sichaza ingozi ngayinye nendlela yokugwema.

Njengomkhiqizi ochwepheshe wezindwangu zokushisa okuphezulu kwe-PTFE, i-Jiangsu Aokai New Materials yabelana nawe ngolwazi olufanele lwemboni. I-Edge warping kanye nokuwa kumatheyipu okushisa aphezulu e-PTFE akuvamile ukubangelwa isici esisodwa, kodwa umphumela wemiphumela ehlanganisiwe yokukhetha okungalungile kwe-tape,

I-Jiangsu Aokai New Materials, umkhiqizi ochwepheshile wamateyipu ashisa kakhulu e-PTFE, uyakuthatha ukuze ufunde kabanzi. Lapho ukhetha izinto zokukhishwa zezindwangu ze-PTFE ezishisa kakhulu, ifilimu yokukhishwa kwe-PET, iphepha lokukhishwa kwengilazi kanye nephepha lokukhishwa kwe-kraft kuletha umehluko ocacile ekuzinzeni kwesitoreji.

Njengomkhiqizi ochwepheshe we-PTFE itheyiphu yokushisa okuphezulu, i-Jiangsu Aokai New Materials ikunikeza incazelo enemininingwane. Enqubweni yokushisa yomshini wokunyathelisa we-Flexible Printed Circuit Boards (FPC), itheyiphu ye-PTFE yokushisa okuphezulu ikhuluma ngezinkinga ezimbili eziyinhloko — ukushwabana kwe-substrate nokudluliswa kwe-adhesive —
