PCB yolimba komanso yosinthika - ukadaulo wapamwamba kwambiri

Mu positi iyi yabulogu, timayang'ana mozama zaukadaulo wama PCB okhwima ndikuwona momwe akusinthira dziko lamagetsi.

M'munda wosinthika wa zida zamagetsi, zatsopano zakhala mwala wopambana. Opanga zamagetsi amayesetsa nthawi zonse kukonza magwiridwe antchito a chipangizocho, kupititsa patsogolo magwiridwe antchito, ndikuchepetsa kukula. Kuti akwaniritse izi, mainjiniya ndi opanga akuyamba kugwiritsa ntchito luso laukadaulo lotchedwa rigid-flex PCBs. Kupereka kusinthasintha kosayerekezeka ndi kudalirika, matabwa apamwambawa asintha makampani opanga zamagetsi, kuwapanga kukhala gawo lofunika kwambiri la chitukuko cha zipangizo zamakono.

Rigid-flex PCB, yomwe imadziwikanso kuti flex-rigid PCB, imaphatikiza zabwino zama board okhazikika komanso osinthika kukhala gawo lophatikizika. Ma board awa amapangidwa ndi magawo osinthika omwe amalola kuti kuzungulira kupindike, kupindika, ndikugwirizana ndi mawonekedwe osiyanasiyana, pomwe magawo olimba amapereka kukhazikika ndikuthandizira kapangidwe kake. Kuphatikizika kwapadera kumeneku kumapereka ufulu wosayerekezeka wa mapangidwe, kulola mainjiniya kupanga zida zomwe kale zinali zosayerekezeka.

Chimodzi mwazofunikira zaukadaulo wama board a rigid-flex ndi mawonekedwe awo amitundu yambiri.Mosiyana ndi mapanelo olimba achikhalidwe, omwe amakhala ndi gawo limodzi, mapanelo okhazikika amatha kukhala ndi zigawo zingapo, zomwe zimawonjezera mwayi wopanga. Kukhoza kukhala ndi zigawo zosiyana pamagulu osiyanasiyana a bolodi kumalola kugwiritsa ntchito bwino malo omwe alipo, kupanga ma PCB okhwima omwe ali abwino kwa zipangizo zazing'ono zamagetsi.

Mapangidwe amitundu yambiri a PCB okhwima amathandiziranso kuphatikiza kwa mabwalo ovuta.Akatswiri tsopano atha kuphatikizira zopanga zovuta, monga zolumikizira zolimba kwambiri ndi zida zomveka bwino, m'zida zawo popanda kusiya ntchito kapena kudalirika. Kuthekera kodabwitsa kumeneku kumatsegula njira zopangira matekinoloje apamwamba kwambiri monga zobvala, zida zamankhwala komanso zowonetsera zosinthika.

Kuphatikiza apo, kulimba kwamakina ndi kudalirika kwa ma PCB okhwima ndi abwino kwambiri.Magawo osinthika amapangidwa ndi zinthu za polyimide, zomwe zimadziwika ndi kukhazikika kwake kwamafuta, kukana mankhwala komanso mphamvu zamakina. Kapangidwe kolimba kameneka kamathandizira ma PCB olimba kuti athe kupirira zovuta zachilengedwe, kuphatikiza kutentha kwambiri, kugwedezeka ndi kugwedezeka. Zotsatira zake, zida zogwiritsa ntchito ma PCB okhwima zimatha kugwira ntchito bwino m'malo ovuta, potero kukulitsa kuchuluka kwa ntchito m'mafakitale.

Kugwiritsa ntchito ma PCB okhazikika pazida zamagetsi kumathanso kupititsa patsogolo kukhulupirika kwa ma siginecha ndikuchepetsa kusokoneza kwamagetsi (EMI).Magawo osinthika amathandizira kuchepetsa kugwedezeka ndikuchepetsa kutayika kwa ma siginecha, kuwonetsetsa kufalikira kodalirika komanso koyenera kwa ma siginecha amagetsi. Kuphatikiza apo, ma PCB olimba osinthika amapereka chitetezo chapamwamba cha EMI, kuchepetsa chiopsezo cha ma radiation a electromagnetic kusokoneza zigawo zapafupi kapena kukhudza magwiridwe antchito onse a chipangizocho. Izi zimapangitsa ma PCB okhwima kukhala abwino pamapulogalamu apamwamba kwambiri monga makina olumikizirana opanda zingwe ndi zamagetsi zamagalimoto.

Ma PCB osasunthika amangowonjezera magwiridwe antchito komanso kudalirika kwa zida zamagetsi, komanso amathandizira kupulumutsa ndalama panthawi yopanga.Kuphatikiza ntchito zingapo pa bolodi limodzi kumachepetsa kufunika kwa zigawo zina zowonjezera komanso kumathandizira kuphatikiza, potero kumachepetsa ndalama zopangira ndikuwonjezera zokolola. Kuphatikiza apo, mawonekedwe ophatikizika a ma PCB okhwima amalola kupondaponda kwazida zing'onozing'ono, kupulumutsa zinthu ndi ndalama zonyamula.

Powombetsa mkota, ma PCB osasunthika asintha dziko lamagetsi popereka ukadaulo wapamwamba womwe umakwaniritsa zosowa za zida zamakono.Ma board ozungulira osinthika komanso odalirikawa amapereka kusinthasintha kwa mapangidwe, mapangidwe amitundu ingapo, kukhazikika kwamakina, kukhulupirika kwa chizindikiro, kuchepetsedwa kwa EMI ndi kupulumutsa mtengo. Pogwiritsa ntchito ma PCB okhazikika, mainjiniya ndi opanga amatha kukankhira malire aukadaulo ndikupereka matekinoloje opambana pamsika. Pamene makampani opanga zamagetsi akupitirizabe kusinthika, zikuwonekeratu kuti ma PCB okhwima-osinthika adzakhala ndi gawo lalikulu pakupanga tsogolo la zipangizo zamagetsi.
