Ma board osinthika osindikizidwa ndi mtundu wopindika wa bolodi wozungulira wopangidwa pazifukwa zingapo. Ubwino wake pama board achikhalidwe akuphatikiza kuchepa kwa zolakwika zapamsonkhano, kulimba mtima m'malo ovuta, komanso kutha kusamalira masinthidwe amagetsi ovuta kwambiri. Ma board ozungulirawa amapangidwa pogwiritsa ntchito zojambula zamkuwa za electrolytic, zinthu zomwe zikuwonetsa mwachangu kuti ndizofunikira kwambiri pamafakitale amagetsi ndi kulumikizana.
Momwe Ma Flex Circuits Amapangidwira
Ma Flex Circuits amagwiritsidwa ntchito pamagetsi pazifukwa zosiyanasiyana. Monga tanena kale, imachepetsa zolakwa za msonkhano, imagwira ntchito bwino ndi chilengedwe, ndipo imatha kugwira ntchito zamagetsi zovuta. Komabe, itha kuchepetsanso ndalama zogwirira ntchito, kuchepetsa kulemera ndi zofunikira za malo, ndikuchepetsanso malo olumikizirana omwe amawonjezera bata. Pazifukwa zonsezi, ma flex circuits ndi amodzi mwazinthu zamagetsi zomwe zimafunidwa kwambiri pamsika.
A flexible kusindikizidwa derawapangidwa ndi zigawo zikuluzikulu zitatu: Makondukita, zomatira, ndi zoteteza. Kutengera ndi mawonekedwe a ma flex circuits, zida zitatuzi zimakonzedwa kuti ziyende momwe makasitomala amafunira, komanso kuti azilumikizana ndi zida zina zamagetsi. Zomwe zimagwiritsidwa ntchito kwambiri pa zomatira za flex circuit ndi epoxy, acrylic, PSAs, kapena nthawi zina palibe, pamene zotetezera zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo poliyesitala ndi polyamide. Panopa, timakonda kwambiri okondakitala amene amagwiritsidwa ntchito m’madera amenewa.
Ngakhale zida zina monga siliva, kaboni, ndi aluminiyamu zitha kugwiritsidwa ntchito, zida zomwe zimagwiritsidwa ntchito kwambiri pakuwongolera ndi mkuwa. Chojambula chamkuwa chimatengedwa kuti ndi chinthu chofunikira kwambiri popanga ma flex circuit, ndipo amapangidwa m'njira ziwiri: rolling annealing kapena electrolysis.
Mmene Zojambula za Copper Zimapangidwira
Anagulung'undisa annealed mkuwa zojambulazoamapangidwa mwa kugubuduza mkangano mapepala amkuwa, kupatulira iwo pansi ndi kupanga yosalala mkuwa pamwamba. Mapepala amkuwa amatha kutentha kwambiri komanso kupanikizika kudzera munjira iyi, kumapanga malo osalala ndikuwongolera ductility, bendability, ndi conductivity.
Pakadali pano,electrolytic mkuwa foil amapangidwa pogwiritsa ntchito njira ya electrolysis. Njira yothetsera mkuwa imapangidwa ndi sulfuric acid (ndi zowonjezera zina malinga ndi zomwe wopanga). Selo la electrolytic limayendetsedwa ndi yankho, lomwe limapangitsa kuti ayoni amkuwa adutse ndikutera pamtunda wa cathode. Zowonjezera zitha kuwonjezeredwa ku yankho lomwe lingasinthe mawonekedwe ake amkati komanso mawonekedwe ake.
Njira ya electroplating iyi imapitirira mpaka ng'oma ya cathode ichotsedwa pa yankho. Ng'oma imayendetsanso momwe zojambulazo zidzakuliridwira, monga ng'oma yothamanga kwambiri imakopanso madzi ambiri, kukulitsa zojambulazo.
Mosasamala kanthu za njirayi, zojambula zonse zamkuwa zopangidwa kuchokera ku njira zonsezi zidzathandizidwabe ndi chithandizo chomangirira, chithandizo cha kutentha kwa kutentha, ndi kukhazikika (anti-oxidation) chithandizo pambuyo pake. Mankhwalawa amathandiza kuti zojambulazo zamkuwa zizitha kumangirira bwino zomatira, zimakhala zolimba kwambiri ndi kutentha komwe kumakhudzidwa pakupanga dera losindikizidwa lokhazikika, ndikuletsa oxidation ya zojambulazo zamkuwa.
Rolled Annealed vs Electrolytic
Chifukwa njira yopangira chojambula chamkuwa cha zojambulazo za annealed ndi electrolytic copper ndizosiyana, amakhalanso ndi ubwino ndi zovuta zosiyanasiyana.
Kusiyana kwakukulu pakati pa zojambula ziwiri zamkuwa ndizofanana ndi mapangidwe awo. Chojambula chamkuwa chokulungidwa chidzakhala ndi chopingasa pa kutentha kwabwino, chomwe chimasandulika kukhala kristalo wa lamellar chikakhala ndi kuthamanga kwambiri ndi kutentha. Pakadali pano, chojambula chamkuwa cha electrolytic chimasunga mawonekedwe ake pamatenthedwe abwinobwino komanso kuthamanga kwambiri komanso kutentha.
Izi zimapanga kusiyana mu conductivity, ductility, bendability, ndi mtengo wa mitundu yonse ya zojambula zamkuwa. Chifukwa zojambula zamkuwa zopindidwa nthawi zambiri zimakhala zosalala, zimakhala zowoneka bwino komanso zoyenerera mawaya ang'onoang'ono. Amakhalanso odumphira kwambiri ndipo nthawi zambiri amakhala opindika kuposa zojambula zamkuwa za electrolytic.
Komabe, kuphweka kwa njira ya electrolysis kumatsimikizira kuti zojambula zamkuwa za electrolytic zimakhala zotsika mtengo kusiyana ndi zojambula zamkuwa zopindika. Zindikirani, kuti atha kukhala njira yabwino kwambiri pamizere yaying'ono, komanso kuti ali ndi kukana kupindika koyipa kuposa zojambula zamkuwa zopindidwa.
Pomaliza, zojambula zamkuwa za electrolytic ndi njira yabwino yotsika mtengo ngati ma conductor mumayendedwe osinthika osindikizidwa. Chifukwa cha kufunikira kwa flex circuit mu zamagetsi ndi mafakitale ena, imapanganso zojambula zamkuwa za electrolytic kukhala chinthu chofunikira.
