Flexible Printed Circuit Materials | Polyimide Pcb | Mhangura Pcb | Soldering Circuit Boards

Muchinyorwa chino, tichanyatso tarisisa pazvinhu zvinowanzoshandiswa mukatiflexible akadhindwa redunhu kugadzira.

Flexible akadhindwa maseketi (FPC) akachinja zvakanyanya ndima yemagetsi. Kugona kwavo kukotama kunoita kuti vazivikanwe mumaindasitiri akasiyana siyana anosanganisira aerospace, mota, hutano hwehutano, uye zvemagetsi zvevatengi.

Chimwe chezvinhu zvikuru zvinoshandiswa mukugadzirwa kwemasekete akadhindwa anochinjika ndeye polyimide.Polyimide ndeyepamusoro-inoita polymer ine yakanakisa kugadzikana kwemafuta, kupikisa kemikari uye kuoma kwemechani. Izvi zvivakwa zvinoita kuti ive yakanaka kune anochinjika maseketi sezvo ichikwanisa kushingirira tembiricha yepamusoro uye hutsinye nharaunda pasina kukanganisa kushanda kwayo. Polyimide-based films anowanzo shandiswa se substrates for flexible akadhindwa maseketi.

Pamusoro pe polyimide, chimwe chinhu chinowanzo shandiswa mukuchinjika chakadhindwa chedunhu kugadzira imhangura.Mhangura yakasarudzwa nekuda kwayo yakanakisa magetsi conductivity, corrosion resistance uye ductility. Foil yakatetepa yemhangura inowanzo kunyudzwa kune polyimide substrate kuumba nzira inoitisa yedunhu. Iyo mhangura yemhangura inopa inodiwa magetsi ekubatanidza anodiwa kuti dunhu rishande nemazvo.

Kuti udzivirire mitsara yemhangura uye kuve nechokwadi chehupenyu hurefu hweiyo inoshanduka yakadhindwa yedunhu, chivharo chekuvhara kana solder mask inodiwa.Kufukidzira ndeye thermoset adhesive firimu rinowanzo kuisirwa kumatunhu edunhu. Inoshanda sechidziviriro chekudzivirira, ichidzivirira mhangura yemhangura kubva kune zvakatipoteredza zvinhu zvakadai semvura, guruva, uye kukuvara kwemuviri. Iyo yekuvhara zvinhu inowanzova polyimide-yakavakirwa firimu, iyo ine yakakwirira yekubatanidza simba uye inogona kusungirirwa zvakasimba kune polyimide substrate.

Kuti uwedzere kusimba uye kushanda kwemaseketi akadhindwa anochinjika, zvinhu zvekusimbisa senge tepi kana zvinhu zvekusimbisa zvinowanzoshandiswa.Wedzera zvigadziriso kune dzimwe nzvimbo dzedunhu uko kunodiwa kuwedzera simba kana kuomarara. Zvinhu izvi zvinogona kusanganisira sarudzo dzakasiyana-siyana, senge polyimide kana polyester firimu, fiberglass, kana kunyange simbi foil. Kusimbisa kunobatsira kudzivirira masekete kubva kubvaruka kana kuputsika panguva yekufamba kana kushanda.

Uye zvakare, mapadhi kana macontacts anowedzerwa kuti afambise kubatana pakati peinochinjika yakadhindwa redunhu uye zvimwe zvikamu zvemagetsi.Aya mapadhi anowanzo kugadzirwa kubva musanganiswa wemhangura uye solder-resistant zvinhu. Bonding pads inopa chimiro chinodiwa chekutengesa kana kubatanidza zvinhu zvakaita seyakabatanidzwa maseketi (ICs), resistors, capacitors, uye majoini.

Kuwedzera kune zviri pamusoro epakati zvinhu, zvimwe zvinhu zvinogona zvakare kuwedzerwa panguva yekugadzira maitiro zvichienderana nezvinodiwa chaizvo.Semuenzaniso, zvinonamira zvinogona kushandiswa kubatanidza zvidimbu zvakasiyana zvemasekete akadhindwa akadhindwa pamwechete. Izvi zvinonamatira zvinosimbisa chisungo chakasimba uye chakavimbika, zvichibvumira dunhu kuchengetedza kuvimbika kwayo kwemaitiro. Silicone adhesives anowanzo shandiswa nekuda kwekuchinjika kwavo, yakakwirira tembiricha kuramba, uye yakanakisa yekubatanidza zvivakwa.

Pakazere, zvinhu zvinoshandiswa mukugadzirwa kwemaseketi akadhindwa anochinjika anonyatso kusarudzwa kuti ave nechokwadi chekushanda kwakakwana uye kusimba.Iko kusanganiswa kwe polyimide se substrate, mhangura ye conductivity, pamusoro pekudzivirira, zvinhu zvekusimbisa zvekuwedzera simba, uye mapedhi ezvikamu zvekubatanidza zvinogadzira yakavimbika uye inoshanda zvizere yakadhindwa yedunhu. Kugona kwemaseketi aya kuchinjika kune akasiyana maapplication, anosanganisira akakomberedzwa nzvimbo nenzvimbo dzakasimba, zvinoita kuti zvive zvakakosha mumidziyo yemagetsi yemazuva ano.

Muchidimbu, anochinjika akadhindwa edunhu zvinhu senge polyimide, mhangura, akafukidzira, anosimbisa, anonamira, uye mapadhi zvinhu zvakakosha mukugadzira anogara uye anochinjika emagetsi maseketi.Zvinhu izvi zvinoshanda pamwe chete kuti zvipe zvinodikanwa zvemagetsi zvinongedzo, kudzivirira uye simba remagetsi rinodiwa mumidziyo yemagetsi yanhasi. Sezvo tekinoroji iri kuramba ichishanduka, zvinhu zvinoshandiswa mukugadzirisa zvakadhindwa zvedunhu kugadzira zvinogona kuenderera mberi, zvichigonesa mamwe maapplication matsva.
