Katundu ndi njira zosankhira zida zopangira ma board osinthika

(1) FPC gawo lapansi

Polyimide chimagwiritsidwa ntchito ngati nkhani ya bolodi dera dera, amene ndi kutentha zosagwira ndi mkulu mphamvu zakuthupi polima. Ndi zinthu zopangidwa ndi polima zopangidwa ndi DuPont. Polyimide yopangidwa ndi DuPont amatchedwa Kapton. Kuphatikiza apo, mutha kugulanso ma polyimides opangidwa ku Japan, omwe ndi otsika mtengo kuposa DuPont.

Imatha kupirira kutentha kwa 400 ℃ kwa masekondi 10 ndipo imakhala yolimba 15000-30000 psi.

Gawo la makumi awiri ndi asanu μ M gawo lokulirapo la FPC ndiye wotsika mtengo kwambiri ndipo amagwiritsidwa ntchito kwambiri. Ngati bolodi losinthasintha liyenera kukhala lolimba, 50 iyenera kusankhidwa μ M maziko. M’malo mwake, ngati bolodi loyendetsa bwalo likuyenera kukhala lofewa, sankhani zakuthupi za 13 μ M.

Katundu ndi njira zosankhira zida zopangira ma board osinthika

(2) Transparent zomatira za FPC gawo lapansi

Amagawidwa epoxy resin ndi polyethylene, zonsezi ndi zomata za thermosetting. Mphamvu ya polyethylene ndiyotsika kwambiri. Ngati mukufuna kuti dera lozungulira likhale lofewa, sankhani polyethylene.

Kuchuluka kwa gawo lapansi ndi zomatira zowonekera pamenepo, kumakhala kovuta kwa board board. Ngati bolodi la dera lili ndi malo akuluakulu opindika, gawo laling’ono komanso zomata zowonekera ziyenera kusankhidwa momwe zingathere kuti muchepetse kupsinjika komwe kumayambira mkuwa wamkuwa, kuti mwayi waming’alu yaying’ono muzitsulo zamkuwa ndizochepa. Zachidziwikire, m’malo amenewa, matumba amodzi ayenera kusankhidwa momwe angathere.

(3) FPC zojambulazo zamkuwa

Amagawidwa mkuwa wokhala ndi kalendala komanso mkuwa wama electrolytic. Mkuwa wa kalendala ali ndi mphamvu yayikulu komanso kupindika, koma mtengo wake ndiokwera mtengo. Mkuwa wamagetsi ndi wotchipa kwambiri, koma uli ndi mphamvu zochepa ndipo ndi wosavuta kuthyola. Amagwiritsidwa ntchito nthawi zambiri pomwe amapindika pang’ono.

The makulidwe a zojambulazo mkuwa adzasankhidwa malinga ndi m’lifupi osachepera ndi katemera osachepera a kutsogolera. Wocheperako zojambulazo zamkuwa, ndizocheperako m’lifupi ndikutalikirana komwe kumatheka.

Mukamasankha mkuwa wokhala kalembedwe, samalani kalozera wazitsulo zamkuwa. Kuwongolera kosalala kwa zojambulazo zamkuwa kumayenderana ndi kuwongolera koyenda kwa bolodi.

(4) Kanema woteteza komanso zomatira zowonekera

Momwemonso, 25 μ M yachitetezo imapangitsa bolodi loyenda mosavuta kukhala lolimba, koma mtengo wake ndi wotsika mtengo. Pabwalo loyendetsa likulumikiza kwambiri, ndibwino kuti musankhe filimu yoteteza 13 μ M.

Zomatira zomata zimaphatikizidwanso mu epoxy resin ndi polyethylene. Bungwe loyendetsa dera logwiritsa ntchito epoxy resin ndilovuta. Pambuyo pokanikiza kotentha, zomata zowonekera bwino zimachotsedwa m’mphepete mwa kanema woteteza. Ngati kukula kwa pad kumakhala kokulirapo kuposa kutsegulira kwa filimu yoteteza, zomatira zotulutsidwazo zimachepetsa kukula kwa pad ndikuyambitsa m’mbali zosazolowereka. Pakadali pano, 13 iyenera kusankhidwa momwe zingathere μ M zomata zowonekera poyera.

(5) Kupaka pad

Pabwalo loyenda lomwe lili lopindika kwakukulu ndipo gawo lina la padilo likuwululidwa, faifi tambala yosankhidwa ndi electroplated + yosanjikiza golide idzalandiridwa, ndipo wosanjikiza wa nickel uzikhala wowonda momwe ungathere: 0.5-2 μ m. Mankhwala osanjikiza agolide 0.05-0.1 μ m.
