I-Flex Circuit, iBhodi yeSekethe eGuquguqukayo e-1 | YMSPCB

Yintoni i-FPC?

IiSekethe eziShicileleyo eziFlebileyo (FPCs), ekwabizwa ngokuba yiFlexible Circuits, okanye iFlex Circuits, ngenkcazo ye-IPC, isekethe eprintiweyo eguquguqukayo lulungiselelo olunepateni yeesekethe eziprintiweyo kunye namacandelo asebenzisa izinto ezisekelwe kwi-flexible kunye okanye ngaphandle kokubeka i-cover eguquguqukayo. Le nkcazo ichanekile, kwaye idlulisela ezinye zezinto ezinokuthi zinikwe iinguqu ezikhoyo kwizinto ezisisiseko, izixhobo zomqhubi, kunye nezixhobo zokukhusela ezikhuselayo. Kodwa ngamanye amaxesha, iisekethe eziguquguqukayo zikwabizwa ngokuba yiFlexible PCB okanye iFlex PCB, kungenxa yokuba ingqikelelo yendalo yabantu abaninzi kukuba isekethe eguquguqukayo yibhodi yesekethe eprintiweyo (PCB) equlathe ifilimu ebhetyebhetye kunye nepateni yabaqhubi bobhedu kuyo. Enyanisweni, i-flexible eprinted circuit iqulethe i-metallic layer of traces, ngokuqhelekileyo ithusi (inqabileyo i-constantan), ebophelelwe kwi-dielectric layer, ngokuqhelekileyo i-polyimide (inqabile i-polyester). Ngokuqinisekileyo, i-multilayer flex circuit ingaba neeleyile ezininzi zetsimbi. Njengomenzi wesekethe eguquguqukayo, i-YMSPCB inokwenza i-8-layer flex PCB. Ukutyeba umaleko conductive kunokuba bhityile kakhulu (0.47mil, 12μ, 1/3oz) ukuba kakhulu (2.8mil, 70μ, 2oz) kunye nobukhulu dielectric zinokwahluka 0.5mil (13μ) ukuba 5mil (125μ). I-Flexible copper clad laminates (i-FCCL) ingaba yinto enye kunye ne-double-side okanye ngaphandle kwe-adhesive layer ukuze idibanise isinyithi kwi-substrate. Iisekethe eziguquguqukayo (FPC) zisetyenziselwa ubuninzi bezicelo, ukusuka kwiimveliso zabathengi ezisezantsi ukuya kwezona zixhobo ziphezulu zomkhosi kunye nezorhwebo. Akunjalo nje ukuba uluhlu lwezixhobo ezisetyenziselwa ukwenza ezi sekethe zihluke kakhulu ekusebenzeni njengoluhlu lweemveliso ezisetyenziswa kuzo. Ii-PCB eziguquguqukayo zisetyenziswa ngokubanzi kwizixhobo zombane njengenxalenye eyimfuneko enikezela ngezibonelelo zokuba zicutheke, zibhitye, kwaye ziphepheke kakhulu. Njengomenzi wesekethe oguquguqukayo othembekileyo, sixhasa zonke iintlobo ze-1-8 iileya eziguquguqukayo zokwenziwa kweesekethe, kubandakanywa iisekethe eziguquguqukayo ezinonxibelelwano lwe-thru-hole, ukungcwatywa kunye / okanye ukungaboni ngoqhagamshelo, ukungcwatywa kunye ne-microvia eyimfama. Ngapha koko, i-YMSPCB ixhasa i-ink yekhabhoni, i-inki yesilivere, i-constantan, kunye ne-hatch impedance elawulwa ziisekethe eziguquguqukayo.

Iifoyile zobhedu ezahlukeneyo ezisetyenziswa kwiFlex Circuit

[Inkcazelo ngeNkqubo]

Ifoyile yobhedu esetyenziswa kwi-FPC ixhomekeke kwizicelo.

[Inkqubo Jikelele]

Izinto zefoyile yobhedu ezisetyenziswa kwi-PCB eqhelekileyo zineendidi ezimbini, ifoyile yobhedu ene-electrodeposited kunye nefoyile yobhedu esongiweyo, kwaye isetyenziswe kwizicelo ezahlukeneyo.

I-Electrodeposited copper foil isetyenziswa kwi-non-dynamic flexure applications Inkqubo yokwenziwa kwefoyile yobhedu eqengqelekayo iya kudala uxinzelelo olukhulu kwaye emva koko ifune i-annealing.After annealing, ifoyile yobhedu eqengqelekisiweyo inesakhiwo esifanelekileyo sokutya okuziinkozo ukunqanda ukusasazeka kokuqhekeka.Yiyo loo nto inokumelana nokuguquguquka.
