Ubushyuhe bwo hejuru bwerekana kaseti zifatika zikoreshwa mubushyuhe bwo hejuru bukora.Hamwe nimikorere nyamukuru yo gukuramo nta bisigara, kaseti yubushyuhe bwo hejuru ikoreshwa cyane cyane nko guhisha no kurinda ibikorwa mugihe cyo gutwika ifu, Gupanga, gucapa imbaho zumuzunguruko, kugurisha imashini hamwe no gushiraho SMT.Irashobora gukoreshwa muburyo butandukanye bwo gukoresha inganda, nk'inganda za elegitoroniki, inganda zitwara ibinyabiziga, inganda zo mu kirere, n'ibindi.
Hano turashaka gutondekanya kaseti ndende nkuko bikurikira:
Ubwa mbere, ubushyuhe bwo hejuru burashobora kugabanwa ukurikije firime zitandukanye.
Ikarita ya Polyimide,nanone yitwa Kapton cyangwa Urutoki rwa Zahabu, nicyo kintu cyiza cyane cyo kurwanya ubushyuhe ku isoko hamwe nigihe gito ukoresheje ubushyuhe bwo hejuru kugirango ube 350 ℃.Ubunini rusange bwa firime ya Kapton ni 12.5um, 25um, 35um, 50um, 75um, 100um na 125um, kandi uruganda rwacu rushobora kandi gutunganya ubundi bunini budasanzwe nka 150um, 200um cyangwa 225um nkuko umukiriya abisaba.Ibara rya Amber n'Umukara ni ibara ryibiri risanzwe, kandi ibara ry'umukara rishobora no gukorwa nk'urumuri cyangwa matte yo kurangiza.Andi mabara nka Icyatsi, Umutuku cyangwa Transparent arashobora kandi guhindurwa hamwe na MOQ hamwe nigiciro kinini.
Polyester nayo mu magambo ahinnye yitwa PET (Izina ryimiti ni polyethylene terephthalate, nanone yitwaMYLAR kaseti).Ubushyuhe bwayo bwo gushonga ni 240 ℃, naho ubushyuhe bwo hejuru bukora ni 230 ℃, mugihe ubushyuhe bwiza bwo gukora buri muri 180 ℃.PET ya firime iranga hamwe nogukwirakwiza kwinshi nigiciro gihenze, ntabwo ikoreshwa gusakaseti irwanya ubushyuhe bwinshiariko kandi nkaMylar insulationcyangwaPET firime ikingira.Amenshi muri firime ya PET ni ibara ryeruye, usibye andi mabara amwe nka Amber ibara, Umutuku, Ubururu nicyatsi kibisi.
- 3. Utwara imyenda y'ibirahure
Imyenda y'ibirahuri ikozwe muri fibre y'ibirahuri kandi ikozwe mu mwenda, naho ubunini muri rusange ni 130um mu ibara ryera.Imyenda y'ibirahure ifite imbaraga zikomeye kandi zirwanya amarira zishobora gukoreshwa nko gupfunyika cyangwa gutunganya transformateur, Moteri, bateri ya lithium cyangwa no gufata neza ibikoresho bya kirombe.
Umwenda wa fibre fibre ikozwe muri Teflon ivurwa kandi igasiga amavuta ya silicone nyuma yo kuvura nanochemiki.Ifite anti-inkoni, ubushyuhe bwo hejuru hamwe n’imiti irwanya imiti, itanga igisubizo kirambye ku mashini zipakira hamwe n’ubushyuhe.Ubunini rusange bwimyenda yikirahure ya Teflon ni 80um na 130um, ubundi bunini budasanzwe nka 50um, 150um cyangwa 250um nabwo bushobora gutegurwa nkuko abakiriya babisabye.
- 5. PTFE
Filime ya PTFE igizwe no guhagarika PTFE resin mu kubumba, gucumura, gukonjesha ubusa.Ifite imiterere myiza ya dielectric, gusaza-kurwanya-kurwanya no kwangirika kwangirika bikunze gukoreshwa mugufunga urudodo, imiyoboro ya doping, pompe no gupfunyika.Hano hari amabara atatu yo guhitamo, ari umweru, umukara n'umukara.
Icya kabiri, kaseti yubushyuhe bwo hejuru irashobora kugabanwa muburyo butandukanye nkuko biri munsi ukurikije ibifatika bitandukanye.
- 1. Ibikoresho bya silicone
Silicone kole ninziza nziza yo kurwanya ubushyuhe bworoshye.Irashobora kurwanya ubushyuhe burebure kuri 260 ℃ n'ubushyuhe buke kuri 300 ℃.Hariho uburyo bubiri bwingenzi bwa silicone glue aribwo buryo bwa BPO catalitiki na sisitemu ya catalitiki ya platine.Sisitemu ya BPO ihendutse kandi ifite ubushyuhe bwiza, ariko izahindura molekile ntoya ya dioxyde ya silicon, izagira ingaruka ku isuku yibicuruzwa.Sisitemu ya catalizike ya platine ifite ubukana buke, ariko isuku nziza, ubusanzwe ikoreshwa mugukora ibicuruzwa bya firime birinda silicone.
- 2. Amashanyarazi
Acrylic glue ifite ubwinshi bwubwiza bwisuku nziza ariko irwanya ubushyuhe buke.Ubukonje bushobora kuva kuri garama 1 ya firime ikingira kugeza kuri 3000gram ya kaseti ya VHB.Mubisanzwe, uko ubukonje buri hejuru, niko birwanya ubushyuhe.Ubushyuhe bwo guhinduranya ibirahuri bya acrylic bifata nka dogere 200, imiterere yifata ya acrylic hejuru ya dogere 200 yarahindutse, kandi ibishishwa biri hasi cyane.Nyuma yo gutwikira birangiye, bigomba gukira no gukura kuri 40 ° C mumasaha 48.Igihe cyakize kandi gikuze kiratandukanye mugihe cyizuba nimbeho, iminsi 3-4 mugihe cyizuba hamwe nicyumweru 1 mugihe cy'itumba.
Kurwanya ubushyuhe buke ni inenge yubwoko bwa acrylic.Nyamara, uruganda rwa kole rwakoze ubushakashatsi bwinshi kugirango ruhindure kole.Kugeza ubu, imaze guteza imbere ubushyuhe bwa dogere 250 hamwe n'ubukonje bwa 7-8N ya acrylic yometse hejurukaseti.
Icya gatatu, ukurikije imiterere itandukanye, ubushyuhe bwo hejuru burashobora kugabanwa nkuko biri hepfo
- 1. Kuruhande rumwe rukumbi kaseti
Kaseti imwe imwe igizwe nubwikorezi nka firime ya Polyimide, firime ya Polyester, umwenda wikirahure, igitambaro cyikirahure cya Teflon cyangwa firime ya PTEFE kandi igashyirwaho igipande kimwe gifata nka silicone yometse cyangwa acrylic.
- 2. Kaseti imwe kuruhande hamwe na firime yo gusohora
Kaseti imwe kuruhande hamwe na firime yo gusohora koresha firime nkuwitwaye yometse kuri silicone cyangwa acrylic yometse hamwe hanyuma ugahuza na firime yo gusohora kugirango urinde uruhande
- 3. Kabiri kuruhande hamwe na firime imwe yo gusohora
Kabiri kuruhande hamwe na firime imwe yo gusohora koresha firime nkuwitwaye impande zombi zometse kuri silicone cyangwa acrylic yometse kandi ihujwe na firime yo gusohora
- 4. Sandwich impande ebyiri kaseti hamwe na firime ebyiri zo gusohora
Kabiri ya kaseti hamwe na firime ebyiri zo gusohora zikoresha firime nka transport yikubye kabiri yometseho kandi igahuzwa na firime ebyiri zo gusohora, igipande kimwe kigahuza uruhande rumwe, ikindi gice kigahuza uruhande, gikoreshwa cyane mugutunganya gupfa.
Hejuru ni ugushira kaseti yubushyuhe bwo hejuru ukurikije uburyo butandukanye.Kubindi bisobanuro nibisobanuro, nyamunekakanda hano.Wabona byinshikaseti irwanya ubushyuhenagupfa gukatankuko ubisaba hano kuri GBS.
