Kodi ma rigid-flex board amalephera bwanji?

Ma board a Rigid-flex circuit ali ndi maubwino apadera opangira, kuphatikiza kukhazikika kwa matabwa olimba ndi kusinthasintha kwa mabwalo osinthika. Kapangidwe ka haibridi kameneka kamapangitsa kuti pakhale zida zamagetsi zowoneka bwino komanso zosunthika, zomwe zimapangitsa kuti zikhale zoyenera pazogwiritsa ntchito zosiyanasiyana kuphatikiza zakuthambo, zida zamankhwala ndi zida zamagetsi zogula. Komabe, monga gawo lina lililonse lamagetsi, ma board ozungulira okhazikika sangalephereke. Kumvetsetsa mitundu yolephereka wamba kungathandize mainjiniya kupanga ma board amphamvu, odalirika. M'nkhaniyi, tiwona njira zolephereka kwambiri zama board ozungulira okhazikika ndikupereka zidziwitso zamomwe mungapewere zolephera izi.

1. Kutopa kosinthasintha:

Chimodzi mwazabwino zazikulu za mapanelo olimba-flex ndi kusinthasintha kwawo, komwe kumawalola kupindika ndikusintha mawonekedwe ovuta. Komabe, kupindika kopitilira muyeso ndi kupindika kumatha kuyambitsa kutopa kwanthawi zonse. Izi zingayambitse ming'alu kapena kusweka kwazitsulo zamkuwa, zomwe zimapangitsa mabwalo otseguka kapena kulumikizana kwapakatikati. Pofuna kupewa kutopa kwapang'onopang'ono, mainjiniya ayenera kuganizira mozama ma bend radius ndi kuchuluka kwa ma bend kuzungulira komwe gulu lingakumane nalo panthawi yautumiki. Kulimbitsa ma frequency osinthika ndi zida zowonjezera zothandizira kapena kugwiritsa ntchito ma flex flex mapangidwe kungathandizenso kuchepetsa zolephera zokhudzana ndi kutopa.

2. Masanjidwe:

Delamination amatanthauza kulekanitsidwa kwa zigawo zosiyanasiyana mkati mwa bolodi lozungulira lokhazikika. Izi zitha kuchitika pazifukwa zosiyanasiyana, kuphatikiza kusalumikizana bwino pakati pa zigawo, kutentha kwa njinga, kapena kupsinjika kwamakina. Delamination imatha kuyambitsa akabudula amagetsi, kutseguka, kapena kudalirika kwa bolodi. Kuti muchepetse chiwopsezo cha delamination, njira zoyenera zoyatsira ziyenera kutsatiridwa panthawi yopanga. Izi zikuphatikiza kugwiritsa ntchito zida zomangira zapamwamba kwambiri, kuwongolera magawo a lamination, ndikuwonetsetsa kuti nthawi yochiritsira yokwanira. Kuphatikiza apo, kupanga ma stackups ndi kugawa mkuwa moyenera komanso kupewa kusintha kwa kutentha kwambiri kungathandize kupewa delamination.

3. Thermomechanical stress:

Ma board a Rigid-flex nthawi zambiri amakhala ndi kupsinjika kwakukulu kwa thermomechanical pa moyo wawo wautumiki. Kupanikizika kumeneku kungayambitsidwe ndi kusintha kwa kutentha, chinyezi, kapena kugwedezeka kwa makina ndi kugwedezeka. Kupsinjika kwa Thermo-mechanical kungayambitse kusweka kapena kulephera kwa solder, zomwe zimayambitsa kudalirika kwamagetsi. Kuti muchepetse zolephera zokhudzana ndi kupsinjika kwa thermomechanical, mainjiniya ayenera kusankha mosamala ndi kuyenerera zida zokhala ndi coefficient yoyenera ya thermal expansion (CTE) pagawo lililonse la bolodi lokhazikika. Kuonjezera apo, kugwiritsa ntchito njira zoyenera zoyendetsera kutentha, monga kugwiritsira ntchito kutentha kwa kutentha kapena matenthedwe, kungathandize kuthetsa kutentha ndi kuchepetsa nkhawa pa bolodi la dera.

4. Kuipitsa ndi dzimbiri:

Kuipitsidwa ndi dzimbiri ndi njira zolephereka wamba pazida zilizonse zamagetsi, ndipo ma board-flex board ndi chimodzimodzi. Kuwonongeka kumatha kuchitika panthawi yopanga kapena chifukwa cha zinthu zachilengedwe monga chinyezi kapena kukhudzana ndi mankhwala. Kumbali ina, kupezeka kwa chinyezi kapena mpweya wowononga nthawi zambiri kumathandizira kuti dzimbiri. Kuyipitsidwa ndi dzimbiri kungapangitse kuti ma board ozungulira achepe kapena kusokoneza magwiridwe antchito. Pofuna kupewa njira zolepherekazi, njira zoyendetsera bwino ziyenera kukhazikitsidwa panthawi yopanga. Kuphatikiza apo, zokutira zofananira kapena encapsulation zitha kupereka chotchinga choteteza kuzinthu zachilengedwe.

5. Kulephera kwa cholumikizira ndi solder:

Zolumikizira ndi zolumikizira zolumikizira ndizofunikira kwambiri pama board ozungulira okhazikika. Kulephera kwa zigawozi kungayambitse kulumikiza kwapakatikati, mabwalo otseguka, kapena kuchepetsa kukhulupirika kwa zizindikiro. Zomwe zimayambitsa kulephera kwa cholumikizira ndi solder zimaphatikizanso kupsinjika kwamakina, kukwera njinga yamoto, kapena njira yolakwika ya soldering. Kuti zitsimikizire kudalirika kwa zolumikizira ndi zolumikizira zogulitsira, mainjiniya amayenera kusankha zida zapamwamba kwambiri, kuwonetsetsa kuti zikuyenda bwino komanso zoyenera, ndikutsatira malangizo omwe akulimbikitsidwa otenthetsera monga kutentha koyenera, kutalika kwa nthawi, ndi kugwiritsa ntchito flux.

Mwachidule, pomwe ma board ozungulira okhazikika amapereka zabwino zambiri, amatha kutengera mitundu ina yolephera. Kumvetsetsa mitundu yolephereka wambayi ndikofunikira kuti mupange mabwalo odalirika komanso olimba. Poganizira zinthu monga flex circuit kutopa, delamination, thermomechanical stress, kuipitsidwa ndi dzimbiri, komanso cholumikizira ndi kulephera kwa solder, mainjiniya amatha kugwiritsa ntchito njira zodzitetezera panthawi yopangira, kupanga ndi kuyesa. Poyang'anitsitsa njira zolephera izi, ma board ozungulira okhazikika amatha kupereka magwiridwe antchito apamwamba komanso moyo wautali wautumiki mumitundu yosiyanasiyana.
