Iyo inochinjika P-ruvara BB, inowanzozivikanwa se Flex pcb, ine insulating polyimide firimu uye yakadhindwa yedunhu pateni. Polyimides insulators, saka nzira inogona chete kupedzwa kana dunhu pateni iri conductive. Kungofanana ne “welding mask” yePCB yakaoma, PCB inochinjika yakafukidzwa ne “chifukidziro” chakatetepa chinodzivirira dunhu kubva kune chero kukanganiswa kwemagetsi. Flex PCB ikozvino yakajairika mune smartphone uye zvekurapa zvikumbiro, kunyanya kana masekete ari pasi pekuchinja kwakanyanya tembiricha uchiramba uchichinjika.

Flexible PCBS inoonekwa se “inochinjika” nekuda kwezvikonzero zvakawanda zvakasiyana. Izvo zviri pachena ndezvekuti matunhu avo anogona kugadziridzwa kuti aenzane nechigadzirwa chaicho. Izvi zvinonyanya kubatsira kana zvasvika kune ma parameter akadai sekusimudzira, kusimba, huremu hwakaderera uye kuchinjika. Mabhodhi edunhu echinyakare haakwanise kusangana nemaitiro akafanana ekugara, fragility uye kugona.

Anochinjika mabhodhi akakwirira kune echinyakare akaomarara mabhodhi kana zvasvika kune zvigadzirwa zvinogumira. Semuenzaniso, kushandisa PCB inochinjika pachinzvimbo cheyakaomarara inogona kuderedza zvakanyanya saizi yechigadzirwa. Vanogona kukotamiswa uye kubhenekerwa kuti vagadzirise kune yepamoyo chigadzirwa. Icho chigadzirwa chose chinogona kuitwa chakareruka uchishandisa zvakafanana zvikamu sezvakaomarara uye zvinorema zvinhu. Nekudaro, mahwendefa anochinjika haachinjiki zvachose. Aya maPCBS ane dzimwe nzvimbo dzakaomarara, asi iwo maseketi anonyanya kuiswa pazvikamu zvinoshanduka, saka zvinogona kugadziriswa zvinoenderana nechigadzirwa. Chengeta nhengo dzakaomarara dzinoshandiswa kutsigira zvinhu kuitira kuti zvichengetedzwe kusvika padanho rakaderera.

1. Kuvakwa:

PCB inoshanduka inogona kuenderana nekuoma kwayo inogona kuvakwa nenzira dzakasiyana siyana. Zvinoenderana nehunyanzvi, nhanho uye zvinhu, tinozvironga sezvizvi:

Single-sided flexible circuit (SSFC) ine imwechete conductive layer ine simbi kana simbi-yakazadzwa polymer pane inoshanduka dielectric firimu; Kazhinji polyimide inoshandisa iyo THT (kuburikidza-gomba) nzira yekuisa chikamu, zvinoreva kuti unogona kushandisa rumwe rutivi kugadzirisa uye kushandura chikamu. Single-sided inochinjika PCB ine kana isina shielding coating inogona kugadzirwa uchishandisa insulating firimu; Nekudaro, kushandiswa kwechivharo chekudzivirira padunhu ndiyo yakajairika tsika nekuti inodzivirira nemagetsi dunhu uye chero EMI. Chimiro uye insulation yeimwe-layer inochinjika PCB inotsanangurwa sezvinotevera:

Sculpted flexible PCB inoyevedza subset ye flexible PCB, chazvino kugadzirwa chine chekuita neimwe nzira inochinjika yekugadzira iyo inogadzira inochinjika dunhu nemaconductor emhangura ehukobvu hwakasiyana pakureba kwayo. Kondakita ari mutete munzvimbo inoshanduka uye akakora munzvimbo yakaoma. Iyi nzira inosanganisira kusarudza etching yemhangura foil kuti uwane kudzika munzvimbo dzakasiyana dzedunhu.

Engraving inochinjika PCB matekiniki anowanzo kusarudzwa kugadzira isina simbi mabati kuti izvi zviitike. Inowedzera kubva kumucheto kusvika kune plug-in yekubatanidza. Iyo yakawedzera nzvimbo inoita kuti majoini e solder agadzikane uye akasimba kupfuura akajairwa flexible circuits.

Multilayer inochinjika PCB ine yakafanana inochinjika sedunhu ine akawanda akaturikidzana. Aya akaturikidzana akabatanidzwa neflat plates. Iwo akaturikidzana e-multi-layer anochinjika PCB anoramba akanyudzwa kuburikidza nemakomba. Aya akawanda maPCBS akafanana neakaomesesa multilayer PCBS kunze kwekusiyana kwezvinhu, mhando, maitiro, uye mutengo. Multi-layer flexible circuits inodhura kupfuura vamwe vavo, asi iva nechokwadi chehutano huri nani. Pazasi pane kuratidzwa kweakawanda-layer PCB.

Chikamu chakasimba chete chikamu chinoshandiswa kujoinha. Iyo yakasara yebhodhi redunhu inoshanduka.

2. Application:

Flexible PCBS inoshandiswa munzvimbo dzinotevera:

Flexible akadhindwa edunhu mabhodhi anowanzoshandiswa kana kuvimbika, kuchinjika uye zvigadzirwa zvisingaremi zvichidikanwa, senge zviri mumidziyo yekurapa. Piritsi rekamera rekumedza rinonzi Pill Cam rinoshandisa dunhu rakatetepa rinochinjika iro rinofanirwa kuvharirwa nemazvo uye kugara. Mushure mekumedza piritsi, vanachiremba nenyanzvi vanogona kunyatsoona tishu kubva mukati memuviri. Mapiritsi anofanirwa kunge ari madiki uye anofanirwa kufamba achichinjika mukati memuviri, saka inochinjika PCBS isarudzo yakakwana, kusiyana neakaomarara uye asina brittle.

B) Smart mafoni:

Kudiwa kwemafoni e “smart” kunoda kuti nharembozha dzive nezvikamu zvidiki uye maseketi anochinjika. Nekudaro, inochinjika PCBS inoita basa rakakosha mumaseketi anoshandiswa mune zvimwe zvikamu zvakakosha zvedunhu, se “simba amplifiers”. Saka mafoni anogona kuve akangwara uye akareruka.

C) Computer Electronics:

Zvigadzirwa zvemagetsi mubhodhi reamai ndizvo musimboti uye mweya wekombuta yemazuva ano. Dhizaini dhizaini inofanirwa kuitiswa nenzira diki, yakapfupika. Naizvozvo, mabhodhi edunhu anochinjika anoshandiswa kuchengetedza zvese zvakagadzikana uye zvidiki.
