Mitundu Yolephereka Wamba ya Mabodi Ozungulira Olimba-Flex: Kuzindikira Kwambiri

Tsegulani:

Mubulogu iyi, tiwona njira zolephereka zamagulu ozungulira okhazikika, zomwe zimayambitsa, ndi mayankho omwe angathe kuwonetsetsa kuti magwiridwe antchito ndi moyo wautali.Pomvetsetsa mitundu yolepherekayi, opanga, mainjiniya ndi opanga amatha kuwongolera kudalirika kwa board board, pamapeto pake kuwongolera mtundu wazinthu komanso kukhutira kwamakasitomala.

Ma board a Rigid-flex circuit ndi otchuka m'mafakitale ambiri chifukwa cha kusinthasintha kwawo, kudalirika, komanso kapangidwe kawo.Pamene teknoloji ikupitirirabe patsogolo, matabwawa amakhala ovuta kwambiri, zomwe zimapangitsa kuti pakhale kufunikira kutsata njira zomwe zingatheke.

1. Kupsinjika kwamakina:

Chimodzi mwazinthu zolephera zazikulu zama board ozungulira okhazikika ndi kupsinjika kwamakina.Kuphatikizika kwapadera kwa zinthu zolimba komanso zosinthika kumapangitsa matabwawa kukhala osavuta kupindika / kupotoza, zomwe zimapangitsa kupsinjika ndi kupsinjika.Pakapita nthawi, kupsinjika kumeneku kungayambitse kusweka, ming'alu, ndi kuwonongeka kwa dera, pamapeto pake kumabweretsa kulephera kwathunthu.Njira yolepherekayi imatha kukulitsidwa ndi zinthu monga kusagwira bwino, kupindika mopitilira muyeso, kapena kusakwanira kwa mapangidwe.

Kuti muchepetse kulephera kokhudzana ndi kupsinjika kwamakina, ndikofunikira kuwongolera mapangidwe ndi njira zopangira.Zothandizira zokwanira, njira zolondola, ndi kusankha zinthu mosamala kungathandize kwambiri kuti gulu la dera lizitha kupirira kupsinjika kwamakina.Kuyesa mozama ndi kusanthula kupsinjika ndikofunikiranso kuti muwone zofooka zomwe zingachitike ndikuwongolera kapangidwe kake moyenera.

2. Kupsinjika kwa kutentha:

Ma board ozungulira olimba-flex amagwira ntchito m'malo osiyanasiyana otentha ndipo chifukwa chake amakhala ndi zolephera zokhudzana ndi kupsinjika kwa kutentha.Kusinthasintha kwa kutentha kumatha kupangitsa kuti zida zosiyanasiyana zikule ndikulumikizana pamitengo yosiyana, zomwe zimatsogolera ku delamination, zovuta zolumikizana ndi solder ndi kulephera kwa kulumikizana.Kutentha kwambiri kapena kutentha kwachangu kumatha kufulumizitsa njira yolephera iyi, kusokoneza magwiridwe antchito onse ndi kudalirika kwa bolodi.

Pofuna kuthana ndi zolephera zokhudzana ndi kupsinjika kwa kutentha, okonza ayenera kuganizira njira zoyenera zoyendetsera matenthedwe panthawi yokonza bolodi ndi kusonkhanitsa.Kuzama kwa kutentha, njira zotenthetsera, ndi njira zowongolera zowongolera zimathandizira kugawa kutentha mofanana ndikupewa kupsinjika kwa kutentha.Kugwiritsira ntchito zipangizo zotentha kwambiri komanso kuyika chigawo mosamala kungachepetsenso mphamvu ya kutentha pa ntchito ya bolodi.

3. Mankhwala ndi chilengedwe:

Ma board ozungulira okhazikika nthawi zambiri amakumana ndi zovuta za mankhwala komanso zachilengedwe, zomwe zimawapangitsa kuti azilephera.Kuwonekera ku chinyezi, zinthu zowononga, ndi zowononga zimatha kuyambitsa makutidwe ndi okosijeni, dzimbiri, ndi kuwonongeka kwa zigawo zozungulira.Kuonjezera apo, zinthu zakunja monga fumbi, zinyalala, ndi chinyezi zimatha kusokoneza kutsekemera ndi zokutira zotetezera, zomwe zimapangitsa kuti matabwa ozungulira azikhala okhudzidwa kwambiri ndi maulendo afupiafupi ndi kulephera kwa magetsi.

Pofuna kupewa kulephera kwa mankhwala ndi chilengedwe, opanga ayenera kuika patsogolo zokutira zovomerezeka, zomwe zimapereka chitetezo ku chinyezi, mankhwala ndi zinyalala.Njira zosindikizira zopanda madzi, monga potting kapena encapsulation, zimatha kuwonjezera kukana kwa bolodi kuzinthu zakunja.Kuphatikiza pa izi, kuwunika pafupipafupi, kuyezetsa ndi kukonza ndikofunikira kuti muzindikire ndikuchepetsa zizindikiro zilizonse zoyamba za kulephera komwe kumachitika chifukwa cha mankhwala kapena chilengedwe.

4. Kudzaza kwamagetsi ndi ESD:

Kuchulukitsitsa kwamagetsi ndi electrostatic discharge (ESD) ndizomwe zimayambitsa kulephera kwa board board.Mapangidwe olakwika amagetsi, mafunde okwera kwambiri, kapena ma spikes adzidzidzi angayambitse zinthu zowotchedwa, kusungunuka kosungunuka, ndi kulephera kwa board board.Electrostatic discharge (ESD) imachitika pamene magetsi osasunthika akwera mwadzidzidzi pa board board, zomwe zingayambitse kulephera koopsa komanso kuwonongeka kosasinthika kwa zida zamagetsi zamagetsi.

Kupewa kuchulukitsidwa kwamagetsi ndi kulephera kokhudzana ndi ESD kumafuna njira zopangira zolimbikira, kuphatikiza njira zodzitetezera, kuwongolera ma voltage, ndi njira zoyambira pansi.Kuphatikiza kwa oteteza maopaleshoni, ma fuse, ndi zida zopondereza za ESD zitha kuchepetsa kwambiri chiwopsezo chakuwonongeka kwamagetsi kapena zochitika za ESD.Kuphatikiza apo, maphunziro a ogwira ntchito pama protocol achitetezo a ESD ndi malo oyendetsedwa ndi opanga amatenga gawo lalikulu pakuchepetsa njira zolepherekazi.

Pomaliza:

Kumvetsetsa mitundu yolephera yodziwika bwino yama board ozungulira okhazikika ndikofunikira kwa opanga, mainjiniya ndi opanga omwe akufuna kuwongolera kudalirika ndikuchepetsa zoopsa zomwe zingachitike.Kupsinjika kwamakina, kupsinjika kwamafuta, zinthu zamankhwala ndi zachilengedwe, kupsinjika kwamagetsi ndi ESD zonse zimawopseza kwambiri magwiridwe antchito oyenera a matabwa ozungulirawa.Pogwiritsa ntchito malingaliro opangira bwino, kusankha zinthu, njira zopangira, ndi njira zoyesera, njira zolephererazi zitha kuchepetsedwa, kuwonetsetsa kuti nthawi yayitali komanso magwiridwe antchito abwino a ma board ozungulira okhazikika.Pamapeto pake, kuthana ndi njira zolepherekazi kumathandizira kuti zinthu ziziyenda bwino, kukhutitsidwa ndi makasitomala, komanso kuchita bwino pamagetsi anu onse.
