I-Polyimide (Kapton) Tape Ichaziwe: Ithiphu Elimelana Nokushisa Okungu-260°C ye-PCB
I-Polyimide (Kapton) Tape Ichazwa: Kungani Ukumelana Nokushisa Okungu-260°C Kubalulekile
I-polyimide tape — evame ukubizwa nge-Kapton tape ngemuva kwalokho — ingenye yamathiphu asebenza kahle kakhulu ekushiseni okuphezulu ekukhiqizeni ama-electronics. Kulo mhlahlandlela, sichaza ukuthi iyini, kungani isilinganiso sayo esingu-260°C sibalulekile, nokuthi ungakhetha kanjani inguqulo efanele inqubo yakho.
Iyini i-Polyimide Tape?
I-polyimide tape iyifilimu elincane le-polyimide (PI) elihlanganiswe ne-adhesive esebenza kahle kakhulu, ngokuvamile i-silicone. Isici sayo esichazayo ukuzinza okukhulu kokushisa: ihlala iphelele futhi ayishiye insalela emazingeni okushisa afika ku-260°C, futhi ingamelana kafushane namazinga aphezulu kakhulu. Iphinde inikeze ukuhlukaniswa kukagesi okuhle kakhulu nokumelana namakhemikhali.
Kungani u-260°C Kubalulekile ku-SMT & Wave Soldering
Ngesikhathi sokuhlanganiswa kwe-PCB, amabhodi adlula ekushiseni okwedlulele:
· I-SMT reflow soldering ifinyelela phezulu cishe ku-240–260°C
· I-Wave soldering iveza amabhodi ku-solder encibilikile kanye namazinga okushisa aphezulu okushisa ngaphambili
Amateyipu ajwayelekile ayashisa, ancibilike, noma ashiye insalela enamathelayo kulawo mazinga okushisa. I-polyimide tape ibambelela ihlanzekile, yingakho iyisinqumo esijwayelekile sokuthi:
· Ukuvala iminwe yegolide nezixhumi ngesikhathi sokushisela
· Ukuvikela izindawo ze-PCB kwi-flux kanye ne-solder splash
· Ukumboza ngesikhathi se-conformal coating
· Ukuqinisa izingxenye ngesikhathi se-reflow
Umphumela: amabhodi ahlanzekile, iziphambeko ezimbalwa, futhi akukho ukulungiswa kabusha okubizayo.
Ukukhetha Ukujiya Ne-Adhesive
I-PI tape iza ngezinhlobo ezahlukene zokujiya, ngayinye ilungele imisebenzi ehlukene:
· 0.03 mm — incane kakhulu, ilungele izindawo eziminyene kanye nokumboza okucophelelayo
· 0.05 mm — yenjongo ejwayelekile, ilinganisa amandla nokuvumelana
· 0.08 mm — yomsebenzi osindayo, yokufaka insulation okudingekayo kanye nokumelana nokuhuzuka
I-silicone adhesive ijwayelekile emsebenzini wokushisa okuphezulu, kodwa futhi singakwazi ukwakha i-acrylic noma amanye ama-adhesive ukuze kuhambisane nenqubo yakho ngqo. Udinga ububanzi obenziwe ngokwezifiso noma i-liner? Sisika nge-tolerance engu-±0.1 mm.
Ngale Kokushisela
· Ukufaka insulate kukhoyili ne-transformer
· Ukufakwa kwe-insulation yebhethri kanye ne-motor winding
· Ukumboza kwe-powder coating kanye nama-3D printing build plates
· Ukulebula kwezinga lokushisa eliphezulu
