Kuwonetsetsa kukhulupirika kwa ma siginecha pamapangidwe a board-flex board board: kalozera pang'onopang'ono

Mawu Oyamba

Kukhulupirika kwa chizindikiro kumagwira ntchito yofunika kwambiri pakugwira ntchito ndi kudalirika kwa zipangizo zamakono zamakono. Kupanga ma board ozungulira okhazikika omwe amaphatikiza kusinthasintha kwa ma flex circuit ndi mphamvu zamapangidwe a board olimba kumabweretsa zovuta zapadera zomwe ziyenera kuthetsedwa kuti zitsimikizire kukhulupirika kwazizindikiro.Mu positi iyi yabulogu, tiwona mfundo zazikuluzikulu ndi njira zapakatikati zopangira ma board ozungulira olimba omwe amasunga kukhulupirika nthawi zonse.Potsatira malangizowa, mainjiniya ndi opanga amatha kuthana ndi zovuta zomwe zingayambitse kusakhulupirika kwazizindikiro ndikupanga ma board apamwamba apamwamba.

1. Mvetserani zovuta za kukhulupirika kwa ma siginali mu kapangidwe ka bolodi lokhazikika

Kuti muwonetsetse kukhulupirika kwa chizindikiro cha bolodi lozungulira lokhazikika, ndikofunikira kumvetsetsa kaye zovuta zomwe zingakhudze magwiridwe ake. Zinthu zina zofunika ndi monga kuwongolera kwa impedance, kuyika kolumikizira, kasamalidwe kamafuta, komanso kupsinjika kwamakina chifukwa chopindika ndi kusinthasintha.

1.1 Kuwongolera kwa Impedans: Kusunga kusakhazikika pamayendedwe azizindikiro ndikofunikira kuti tipewe kuwunikira ndi kutayika.Kuyika koyenera kwa dielectric, njira zowongolera zowongolera, ndi njira zolondola zothetsera ndizofunikira.

1.2. Kuyika kwa cholumikizira: Kuyika mwanzeru zolumikizira ndikofunikira kuti muchepetse kutsitsa kwazizindikiro ndikuwonetsetsa kulumikizana kodalirika.Sankhani malo mosamala kuti muchepetse mphamvu za parasitic, kuchepetsa kutha, ndikupewa kusokoneza.

1.3. Kasamalidwe ka matenthedwe: Zovuta za kutentha monga kutenthetsa m'malo ndi kutentha kosafanana zimatha kusokoneza kukhulupirika kwa chizindikiro.Njira zoyendetsera bwino za kutentha, kuphatikizapo kutayika koyenera kwa kutentha ndi kufufuza njira, ndizofunikira kuti zipitirize kugwira ntchito bwino.

1.4. Kupsinjika kwamakina: Kupinda ndi kupindika kumatha kubweretsa kupsinjika kwamakina pama board ozungulira okhazikika. Kupsinjika kumeneku kungayambitse kuphulika, kusintha kwa impedance, ndi kusokonezeka kwa zizindikiro.Kuganizira mozama za ma bend radius, kulimbitsa madera opindika, ndi kuyika kwa chigawochi kungachepetse mavutowa.

2. Ndondomeko ya sitepe ndi sitepe yotsimikizira kukhulupirika kwa chizindikiro

Kupanga ma board ozungulira okhazikika okhala ndi kukhulupirika kwazizindikiro kumafuna kutsatira malangizo ndi masitepe. Tiyeni tifufuze mu chitsogozo chilichonse kuti timvetsetse bwino.

2.1. Kufotokozera zolepheretsa ndi zofunikira pakupanga: Yambani ndikulongosola zofunikira za polojekiti, kuphatikizapo magetsi, makina, ndi magetsi.Kumvetsetsa zofooka izi kuyambira pachiyambi kungathandize kutsogolera ndondomeko yopangira.

2.2. Gwiritsani ntchito zida zamapulogalamu poyesa kuyerekezera: Gwiritsani ntchito zoyeserera zamagetsi zamagetsi, mapulatifomu owunikira ma siginecha ndi zida zina zamapulogalamu kuti mutengere magwiridwe antchito a board board.Unikani magawo ofunikira monga impedance, crosstalk ndi zowunikira kuti muzindikire zomwe zingachitike ndikupanga kusintha kofunikira.

2.3. Konzani kusanjika: Khazikitsani mapangidwe osanjika bwino kuti aphatikize bwino zigawo zolimba komanso zosinthika.Onetsetsani kuti mwasankha zipangizo zoyenera pagawo lililonse kuti mukwaniritse zofunikira komanso zodalirika. Ganizirani za kuwongolera kwa impedance, kukhulupirika kwa ma signature, komanso kukhazikika kwamakina panthawi yokonzekera ma stackup.

2.4. Tsatirani njira ndi kuyika kwa awiriawiri: Samalani kwambiri ndi njira yotsatirira ndi kuyika kosiyana kuti muchepetse kuwonongeka kwa ma sign.Pitirizani kufufuza m'lifupi mwake, sungani kusiyana pakati pa zizindikiro zothamanga kwambiri ndi zigawo zina, ndipo gwiritsani ntchito njira yobwerera mosamala.

2.5. Kuyika ndi kapangidwe ka cholumikizira: Sankhani mosamalitsa mitundu yolumikizira ndi kuyika kwake kuti muchepetse kutsika kwa ma siginecha.Mukamapanga zolumikizira, chepetsani kutalika kwa njira zazizindikiro, pewani ma vias osafunika, ndipo ganizirani mfundo zamakina opatsira.

2.6. Kuwongolera Kutentha: Gwiritsani ntchito njira zoyendetsera kutentha kuti muteteze kutenthedwa ndi nkhani zotsatila za kukhulupirika kwa chizindikiro.Gawani kutentha mofanana, gwiritsani ntchito mpweya wotentha, ndipo ganizirani kugwiritsa ntchito matenthedwe kuti muthe kutentha bwino.

2.7. Kuchepetsa kupsinjika kwamakina: Zopangira zomwe zimachepetsa kupsinjika kwamakina, monga ma bend radii oyenera, zolimbitsa thupi, ndi madera osinthika kukhala olimba.Onetsetsani kuti mapangidwewo amatha kupirira kupindika ndikupindika popanda kusokoneza kukhulupirika kwa chizindikiro.

2.8. Phatikizani mfundo za kamangidwe ka kupanga (DFM): Gwirani ntchito ndi PCB yopanga ndi ogwirizana nawo kuti muphatikize mfundo za DFM pakupanga.Izi zimatsimikizira kupangidwa, zimachepetsa chiopsezo cha kukhulupirika kwa ma siginecha, ndikuwongolera magwiridwe antchito onse.

Mapeto

Kupanga ma board ozungulira okhazikika okhala ndi kukhulupirika kwazizindikiro zolimba kumafuna kukonzekera mosamala, kusamalitsa mwatsatanetsatane, komanso kutsatira machitidwe abwino. Pomvetsetsa zovuta zapadera zomwe zimakhudzidwa ndi kamangidwe ka board-flex board, mainjiniya ndi opanga amatha kugwiritsa ntchito njira zabwino zowonetsetsa kuti ma siginecha akuyenda bwino. Kutsatira malangizo a sitepe ndi sitepe zomwe zafotokozedwa mu positi iyi mosakayikira zidzatsegula njira yopita ku mapangidwe opambana a board board omwe amakwaniritsa kapena kupitilira zomwe amayembekeza. Ndi matabwa ozungulira opangidwa bwino, zipangizo zamagetsi zimatha kupereka ntchito zapamwamba, zodalirika, ndi moyo wautali.
