Flexible circuits, inozivikanwawo se flexible printed circuit boards (PCBs), zvinhu zvakakosha zvezvizhinji zvemazuva ano zvigadzirwa zvemagetsi.Kuchinjika kwavo kunovabvumira kuchinjika kune akasiyana maumbirwo uye saizi, zvichiita kuti ive yakanakira maapplication ayo anoda imwe dhigirii rekukotama kana kukotama.Kugadzirwa kwema flex circuits kunosanganisira matanho akati wandei, kusanganisira kusarudzwa kwezvinhu zvakakodzera.Mune ino blog post, isu tichaongorora zvakajairwa zvinhu zvinoshandiswa muflex wedunhu kugadzirwa uye basa ravanoita mukuona kusimba uye kushanda kwemaseketi aya.
Chimwe chezvinhu zvekutanga zvinoshandiswa mukushandura dhizaini kugadzira polyimide.Polyimide ndeye yakakwira tembiricha inodzivirira epurasitiki zvinhu zvinokwanisa kumira nharaunda dzakaomarara.Iyo ine yakanakisa kupisa kugadzikana uye magetsi insulating zvivakwa, zvichiita kuti ive yakakodzera kushandiswa mumaseketi anochinjika anogona kuratidzwa kune tembiricha yepamusoro kana zvakanyanya mamiriro.Polyimide inowanzoshandiswa sechinhu chakadzika kana substrate yemaseketi anochinjika.
Chimwe chinhu chinowanzoshandiswa mu flex circuit kugadzira imhangura.Mhangura yakanaka conductor yemagetsi, ichiita kuti ive yakakodzera kufambisa masaini emagetsi mumasekete anochinja.Iyo inowanzo simbiwa kune polyimide substrate kuti iite conductive traces kana wiring padunhu.Mhangura yemhangura kana mapepa akaonda emhangura anowanzoshandiswa mukugadzira.Ukobvu hwemhangura layer hunogona kusiyana zvichienderana nezvinodiwa zvekushandisa.
Adhesive zvinhu zvakakoshawo mu flex circuit kugadzira.Adhesives anoshandiswa kubatanidza zvikamu zvakasiyana zve flex circuit pamwe chete, kuve nechokwadi kuti dunhu rinoramba rakasimba uye rinoshanduka.Zvinhu zviviri zvakajairwa zvekunamira zvinoshandiswa mukuchinja kwedunhu kugadzira ndeye acrylic-based adhesives uye epoxy-based adhesives.Acrylic-based adhesives inopa yakanaka kuchinjika, nepo epoxy-based adhesives yakanyanya kuomarara uye yakasimba.
Pamusoro pezvishandiso izvi, zvivharo kana solder mask zvinhu zvinoshandiswa kuchengetedza maitiro ekuitisa pane inotenderera redunhu.Pamusoro pezvinhu zvinowanzogadzirwa zve polyimide kana liquid photoimaging solder mask (LPI).Iwo anoiswa pane conductive traces kuti ape insulation uye azvidzivirire kubva kune zvakatipoteredza zvinhu zvakaita sehunyoro, guruva uye makemikari.Iyo yekuvharira layer inobatsirawo kudzivirira mapfupi maseketi uye inovandudza kuvimbika kwese kweiyo flex circuit.
Chimwe chinhu chinowanzoshandiswa mukugadzirisa flex circuit kugadzira mbabvu.Mbabvu dzinowanzo gadzirwa neFR-4, murazvo unodzoreredza fiberglass epoxy zvinhu.Iwo anoshandiswa kusimbisa dzimwe nzvimbo dze flex circuit inoda imwe rutsigiro kana kuoma.Mbabvu dzinogona kuwedzerwa munzvimbo dzine zvibatanidza kana zvikamu zvakasimudzwa kuti zvipe simba rakawedzerwa uye kugadzikana kudunhu.
Pamusoro pezvinhu izvi zvekutanga, zvimwe zvinhu zvakaita semasoja, machira ekudzivirira, uye zvinhu zvinodzivirira zvinogona kushandiswa panguva yekugadzira flex circuit.Chimwe nechimwe chezvishandiso izvi chinoita basa rakakosha pakuita, kusimba uye kuvimbika kwemaseketi anochinjika mumhando dzakasiyana dzekushandisa.
Muchidimbu, zvinhu zvinowanzo shandiswa mukugadzira flex circuit yekugadzira zvinosanganisira polyimide seyo substrate, mhangura senzira inobatika, inonamira zvinhu zvekusungirira, inovhara matanda ekudzivirira nekudzivirira, uye mbabvu dzekusimbisa.Chimwe nechimwe chezvishandiso izvi chinoshanda chakananga chinangwa uye pamwe chete chinosimudzira mashandiro uye kuvimbika kweiyo flex maseketi.Kunzwisisa uye kusarudza zvinhu zvakafanira kwakakosha pakugadzira emhando yepamusoro maseketi anochinjika anosangana nezvinoda kuomesesa zvemidziyo yemagetsi yemazuva ano.
