Options for conductive layers of flexible circuit boards

Mune ino blog, isu tichaongorora dzakasiyana sarudzo dziripo dze conductive layer muma flexible circuit board.

Flexible redunhu mabhodhi, anozivikanwawo seanochinjika akadhindwa edunhu mabhodhi (PCBs) kana anochinjika zvemagetsi, akawana mukurumbira wakakura mumakore achangopfuura nekuda kweakasiyana maitiro uye mabhenefiti pamusoro pechinyakare maPCB akaomarara. Kugona kwavo kukotama, kumonyoroka uye kukotama kunoita kuti ive yakanakira kushandiswa kwakasiyana-siyana mumaindasitiri akadai semotokari, aerospace, hutano uye tekinoroji inopfeka.

Chimwe chezvikamu zvakakosha zve flexible circuit board ndiyo conductive layer. Aya mataira ane basa rekufambisa masaini emagetsi uye kufambisa mafambiro emagetsi mudunhu rese. Kusarudzwa kwezvinhu zvinoitisa zvezvikamu izvi zvinoita basa rakakosha mukuita kwese uye kuvimbika kweiyo inoshanduka PCB.

1. Copper foil:

Copper foil ndiyo inonyanya kushandiswa conductive layer zvinhu mumabhodhi anochinjika edunhu. Iyo ine yakanakisa conductivity, kuchinjika uye kusimba. Foil yemhangura inowanikwa muhukobvu hwakasiyana, kazhinji 12 kusvika 70 microns, inobvumira vagadziri kusarudza hukobvu hwakakodzera zvichienderana nezvinodiwa zvekushandisa kwavo. Iyo foil yemhangura inoshandiswa mumabhodhi edunhu anochinjika inowanzobatwa neadhesive kana yekubatanidza mumiriri kuti ive nechokwadi chekunamatira kwakasimba kune inochinjika substrate.

2. Inki inoitisa:

Conductive inki imwe sarudzo yekugadzira conductive layer mumabhodhi anochinjika edunhu. Ingi iyi ine ma conductive particles akaturikwa mu liquid medium, semvura kana organic solvent. Inogona kuiswa kune inochinjika substrates uchishandisa akasiyana matekiniki, senge kudhinda skrini, inkjet kudhinda kana spray coating. Conductive ingi zvakare ine mukana wakawedzerwa wekugadzira yakaoma dunhu mapatani ayo anogona kugadziridzwa kuti asangane neyakagadzika dhizaini zvinodiwa. Nekudaro, dzinogona kunge dzisiri dzakaita senge foil yemhangura uye dzinogona kuda mamwe machira ekudzivirira kuti awedzere kusimba.

3. Nama inoitisa:

Conductive adhesives imwe nzira kune yechinyakare solder nzira dzekugadzira conductive layer mumabhodhi anochinjika edunhu. Aya anonamatira ane ma conductive particles, akadai sesirivha kana kabhoni, akaparadzirwa mu polymer resin. Inogona kushandiswa kusungira zvikamu zvakananga kune inoshanduka substrates, kubvisa kudiwa kwekutengesa. Conductive adhesives inofambisa magetsi zvakanaka uye inogona kumira kukotama nekukotama pasina kukanganisa kuita kwedunhu. Zvisinei, vanogona kunge vane mazinga akakwirira ekupikisa kana achienzaniswa nemhangura foil, iyo inogona kukanganisa kushanda kwese kwedunhu.

4. Firimu resimbi:

Mafirimu ane simbi, akadai sealuminium kana sirivheri mafirimu, anogona zvakare kushandiswa se conductive layer mumabhodhi anochinjika edunhu. Aya mafirimu anowanzo vacuum akaiswa pane anochinjika substrates kuti aumbe yunifomu uye inoenderera mberi layer yemakondakita. Metallized mafirimu ane yakanakisa magetsi conductivity uye anogona kuenzanisirwa uchishandisa etching kana laser ablation maitiro. Nekudaro, ivo vanogona kuve nezvinogumira mukuchinjika nekuti simbi dzakaiswa dzinogona kutsemuka kana kudonhedza kana dzichidzokororwa kana kumonyoroka.

5. Graphene:

Graphene, chidimbu chimwe chete chemaatomu ekabhoni akarongwa mune hexagonal lattice, inoonekwa sechinhu chinovimbisa zvinhu zve conductive layer mumabhodhi edunhu anochinjika. Iyo ine yakanakisa magetsi uye yekupisa conductivity, pamwe neakanakisa emakanika simba uye kuchinjika. Graphene inogona kuiswa kune inochinjika substrates uchishandisa nzira dzakasiyana, senge kemikari vapor deposition kana inkjet kudhinda. Nekudaro, mutengo wakakwira uye kuoma kwekugadzirwa kwegraphene uye kugadzirisa parizvino kunomisa kutorwa kwayo kwakapararira mumashandisirwo ekutengesa.

Muchidimbu, pane zvakawanda zvingasarudzwa zve conductive layers mumabhodhi anochinjika edunhu, rimwe nerimwe riine zvaro zvakanakira uye zvarisingakwanisi. Copper foil, conductive inks, conductive adhesives, metallized films uye graphene zvese zvine zvakasarudzika zvivakwa uye zvinogona kugadzirwa kune chaiwo zvinodiwa zvekushandisa kwakasiyana.Vagadziri nevagadziri vanofanirwa kunyatso ongorora sarudzo idzi uye vosarudza yakanyatsokodzera conductive zvinhu zvichibva pazvinhu zvakaita sekuita kwemagetsi, kusimba, kuchinjika, uye mutengo.
