Chinyezi ndi chinyezi zimakhudza magwiridwe antchito a ma rigid-flex board

Mu positi iyi yabulogu, tiwona bwino momwe chinyezi ndi chinyezi chimakhalira pama board ozungulira okhazikika ndikukambirana momwe opanga ndi mainjiniya angachepetse izi.

M'munda wamagetsi, ma board ozungulira okhazikika akukhala otchuka kwambiri chifukwa cha mapangidwe awo apadera komanso magwiridwe antchito osiyanasiyana. Ma matabwa ozungulirawa amakhala ndi zigawo zolimba komanso zosinthika zomwe zimawalola kupindika, kupindika, kapena kupindika kuti agwirizane ndi zida zamagetsi zophatikizika komanso zovuta. Komabe, monga gawo lina lililonse lamagetsi, ma board ozungulira okhazikika satetezedwa kuzinthu zachilengedwe monga chinyezi ndi chinyezi. M'malo mwake, zinthu izi zitha kukhudza kwambiri magwiridwe antchito komanso moyo wautali wa matabwawa.

Chinyezi chonsecho (ponena za kukhalapo kwa nthunzi mumlengalenga) ndi chinyezi (ponena za kuchuluka kwa madzi omwe amapezeka m'chilengedwe) zitha kusokoneza ma board ozungulira okhazikika.Akakumana ndi chinyezi chambiri, chinyezi chimatha kulowa m'magulu ozungulira, kuchititsa dzimbiri zazitsulo ndi zigawo zake. Izi zingayambitse kutayika kwa conductivity ndi nkhani zodalirika. Kuphatikiza apo, chinyezi chimatha kukhudza zida za dielectric zomwe zimagwiritsidwa ntchito pama board ozungulira, zomwe zimapangitsa kuti pakhale mphamvu kapena kutayikira pano. Izi zitha kubweretsa kusokonezedwa kwa ma sign, kuwongolera bwino kwa impedance, ndikuwonongeka kwathunthu kwa board.

Imodzi mwazovuta zazikulu zomwe zimakhala ndi matabwa ozungulira okhwima ndi kukhalapo kwa madera omwe ali ndi ma bend radii osiyanasiyana, omwe angapangitse zofooka zomwe zingatheke.Zikakhala ndi chinyezi, zofookazi zimakhala zosavuta kuwonongeka. Chinyezi chimatha kulowa m'magawo osinthika, kuwapangitsa kutupa kapena kufooketsa, kupangitsa kupsinjika kwakukulu pamagawo olimba ndikupangitsa bolodi kulephera. Kuonjezera apo, kuyamwa chinyezi kungasinthe miyeso ya wosanjikiza wosanjikiza, kuchititsa misalignment ndi wosanjikiza wosanjikiza ndi kulepheretsa ntchito yonse ya bolodi.

Kuti muchepetse zovuta za chinyezi ndi chinyezi pama board ozungulira okhazikika, opanga ndi mainjiniya amagwiritsa ntchito njira zosiyanasiyana.Njira imodzi yodziwika bwino ndiyo kugwiritsa ntchito zokutira zofananira, zomwe zimateteza ku zinthu zachilengedwe, kuphatikiza nthunzi wamadzi ndi chinyezi chamadzimadzi. Zopaka izi nthawi zambiri zimagwiritsidwa ntchito pazitsulo zowonekera kuti zisawonongeke komanso kulimbitsa kudalirika kwa bolodi lozungulira. Komabe, kusankha zomangira zoyenera ndikuwonetsetsa kuti kuphimba koyenera ndikofunikira, chifukwa kuyanika kosakwanira kumatha kupangitsa kuti pakhale chinyezi komanso chitetezo chochepa.

Chinthu chinanso chofunikira ndikusankha zida zoyenera za ma rigid-flex circuit board. Zida zolimbana ndi chinyezi, monga polyimide, nthawi zambiri zimakondedwa ndi zigawo zosinthika chifukwa cha kuyamwa kwake kochepa komanso kukhazikika kwabwino kwambiri. Inen Kuonjezera apo, chotchinga cha chinyezi chingathenso kuphatikizidwa mu mapangidwe a bolodi la dera kuti ateteze chinyezi kuti chisalowe mu wosanjikiza ndikuwononga. Zotchinga izi nthawi zambiri zimapangidwa ndi zinthu zomwe zimakhala ndi mpweya wambiri wamadzi, monga zojambula zachitsulo kapena ma polima apadera.

Kuonjezera apo, kulingalira koyenera kamangidwe kungachepetse zotsatira za chinyezi ndi chinyezi pamagulu ozungulira ozungulira.Kuonetsetsa kuti pali malo okwanira pakati pa zigawo ndi zotsalira kumathandiza kuchepetsa mwayi wa kusamuka kwa chinyezi komanso kuchepetsa chiopsezo cha maulendo afupiafupi. Kuphatikiza apo, kugwiritsa ntchito mawonekedwe oyendetsedwa ndi impedance kumatha kupititsa patsogolo kukhulupirika kwa ma sign ndi kuchepetsa zotsatira za kusintha kwamphamvu kwa chinyezi.

Kuyesa ndi kuyang'anira nthawi zonse n'kofunikanso kuti pakhale kudalirika kwa matabwa ozungulira ozungulira.Kuyesa kwa chilengedwe, monga kutentha ndi kutentha kwa njinga, kumatha kutsanzira zochitika zenizeni padziko lapansi ndikuzindikira zofooka zomwe zingachitike pamapangidwe kapena kupanga. Mayeserowa atha kuthandizira kuzindikira kuwonongeka kapena kulephera kulikonse chifukwa cha kuyamwa kwa chinyezi ndikuwongolera kuwongolera kwamtsogolo.

Powombetsa mkota,chinyezi ndi chinyezi zingakhudze kwambiri magwiridwe antchito ndi kudalirika kwa matabwa ozungulira okhazikika. Kukhalapo kwa chinyezi kungayambitse dzimbiri, kutupa, delamination ndi kusintha kwa dimensional, zomwe zimabweretsa mavuto osiyanasiyana ogwiritsira ntchito. Komabe, mainjiniya ndi opanga amatha kuchepetsa izi pogwiritsa ntchito zida zoyenera, zokutira zoteteza, malingaliro oyenera apangidwe komanso kuyesa mwamphamvu. Pomvetsetsa zotsatira za chinyezi ndi chinyezi pamabwalo ozungulira okhazikika komanso kugwiritsa ntchito njira zochepetsera bwino, zida zamagetsi zimatha kupitiliza kugwira ntchito modalirika m'malo osiyanasiyana.
