I-Flex Circuit, Ibhodi Lesifunda Eliphrintiwe Lesendlalelo elingu-1 | YMSPCB

Yini i-FPC?

Ama-Flexible Printed Circuits (FPCs), ebizwa nangokuthi i-Flexible Circuits, noma i-Flex Circuits, ngencazelo ye-IPC, isekethe ephrintiwe eguquguqukayo iwuhlelo olunephethini lokujikeleza okuphrintiwe kanye nezingxenye ezisebenzisa impahla esekelwe eguquguqukayo enekhava eguquguqukayo noma ngaphandle kwayo. Le ncazelo inembile, futhi idlulisa amandla athile uma kubhekwa ukwehluka okutholakalayo ezintweni eziyisisekelo, izinto zokukhondatha, nezinto zokumboza ezivikelayo. Kodwa ngezinye izikhathi, amasekhethi aguquguqukayo abuye abizwe ngokuthi i-Flexible PCB noma i-Flex PCB, lokho kungenxa yokuthi umqondo wemvelo wabantu abaningi ukuthi isifunda esivumelanayo siyibhodi lesifunda eliphrintiwe eligobekayo (PCB) elihlanganisa ifilimu eguquguqukayo enephethini yamakhondaktha ethusi kuyo. Eqinisweni, umjikelezo ophrintiwe oguquguqukayo uqukethe ungqimba lwe-metallic lwemikhondo, ngokuvamile ithusi (akuvamile ukuba i-constantan), eboshwe kungqimba lwe-dielectric, ngokuvamile i-polyimide (akuvamile ukuba i-polyester). Yiqiniso, i-multilayer flex circuit ingaba nezingqimba eziningi zensimbi. Njengomkhiqizi wesekethe eguquguqukayo, i-YMSPCB ingakha i-PCB enezingqimba eziyi-8. Ukuqina kwesendlalelo se-conductive kungaba mncane kakhulu (0.47mil, 12μ, 1/3oz) kuya kugqinsi kakhulu (2.8mil, 70μ, 2oz) futhi ukujiya kwe-dielectric kungahluka kusuka ku-0.5mil (13μ) kuya ku-5mil (125μ). I-Flexible copper clad laminates (FCCL) ingaba nohlangothi olulodwa futhi izinhlangothi ezimbili noma ngaphandle kwesendlalelo sokunamathela ukuze ibophe insimbi ku-substrate. Ama-Flexible circuits (FPC) asetshenziswa kuzinhlelo zokusebenza eziningi, kusukela emikhiqizweni esezingeni eliphansi kakhulu kuye kwephezulu kakhulu yezempi neyezohwebo. Akukhona nje ukuqondana ukuthi ububanzi bezinto ezisetshenziswayo ukwenza la masekethi ahluke ngokusebenza njengobubanzi bemikhiqizo asetshenziswa kuyo. Ama-PCB aguquguqukayo asetshenziswa kakhulu kumishini kagesi njengengxenye ebalulekile enikeza izinzuzo zokuba minyene, mncane, futhi aphenduleke kakhulu. Njengomkhiqizi wesekethe onokwethenjelwa oguquguqukayo, sisekela zonke izinhlobo zokukhiqiza izingqimba ezingu-1-8 eziguquguqukayo, okuhlanganisa amasekhethi aguquguqukayo anoxhumano lwe-thru-hole, angcwatshwe kanye/noma angaboni ngokuxhuma, ukungcwatshwa nokuxhunywa kwe-microvia eyimpumputhe. Ngaphezu kwalokho, i-YMSPCB isekela uyinki we-carbon, uyinki wesiliva, i-constantan, kanye namasekethe alawulwa yi-hatch impedance aguquguqukayo.

Ama-Foil Ethusi Ahlukene Asetshenziswa Kuseyingi Ye-Flex

[Incazelo Yenqubo]

I-foil yethusi esetshenziswa ku-FPC incike ekusetshenzisweni.

[Inqubo Ejwayelekile]

Izinto ze-copper foil ezisetshenziswa ku-PCB evamile zinezinhlobo ezimbili, ucwecwe lwethusi olufakwe i-electrodeposited kanye ne-foil yethusi egoqwe, futhi isetshenziswa ezinhlelweni ezihlukene.

I-Electrodeposited copper foil isetshenziswa ekusetshenzisweni kokuguquguquka okungaguquguquki Inqubo yokukhiqiza i-foil yethusi egoqiwe izodala ukucindezeleka okukhulu futhi ngemva kwalokho idinga ukukhishwa kwe-annealing, ucwecwe lwethusi olugoqiwe lunokwakheka okusanhlamvu okufanelekile ukuvimbela ukusakazeka kokuqhekeka.Yingakho inokumelana nokuguquguquka.
