Kodi Ma board a PCB Okhazikika Ndi Okhazikika Motani?

Ma PCB olimba osinthika(Ma board ozungulira olimba osinthika) akuyamba kutchuka pazida zamagetsi chifukwa cha mawonekedwe awo apadera omwe amapereka kusinthasintha komanso kusasunthika.Kuphatikizana kumeneku kumapangitsa kusinthasintha kwakukulu kwapangidwe ndi kukhazikika, ndikupangitsa kukhala koyenera kwa ntchito zosiyanasiyana. Komabe, musanagwiritse ntchito matabwawa pazinthu zamagetsi, kulimba kwake kuyenera kumveka.M'nkhaniyi, tiona zinthu zimene zimakhudza durability wa matabwa okhwima kusintha PCB ndi zimene mungachite kuti moyo wawo wautali.

Ubwino Wazinthu ndi Kusankhidwa mu ma PCB osinthika okhazikika:

Kusankhidwa kwa zida zomwe zimagwiritsidwa ntchito popanga PCB yolimba-flex kumatenga gawo lalikulu pakuzindikira kulimba kwake.Zida zapamwamba monga polyimide kapena magawo apadera monga FR-4 amagwiritsidwa ntchito kwambiri chifukwa cha makina awo abwino kwambiri komanso magetsi. Zidazi zimakhala ndi kukana kwambiri kupindika, kusinthasintha, chinyezi ndi kusintha kwa kutentha komwe kumafunikira pazinthu zambiri.

Polyimide, chinthu wamba gawo lapansi mu PCBs olimba-flex, ali ndi kutentha kwambiri bata, kulola bolodi kupirira kutentha kwambiri popanda kusokoneza kukhulupirika kwake.Izi ndizofunika kwambiri pazida zamagetsi zomwe zimatha kukhala ndi kutentha kwambiri kapena kusakhazikika kwachilengedwe.

Kuonjezera apo,polyimide ili ndi coefficient yotsika ya kukulitsa kutentha, zomwe zikutanthauza kuti imakula ndikuchepa pang'ono ndi kusintha kwa kutentha.Izi zimawonetsetsa kuti PCB yokhazikika-yokhazikika imakhalabe yokhazikika komanso imalepheretsa kuwonongeka kapena kulephera kulikonse chifukwa cha kupsinjika kwamafuta.

Magawo apadera monga FR-4 amagwiritsidwanso ntchito kwambiri m'mapangidwe osasunthika chifukwa cha luso lawo lamakina komanso magetsi.FR-4 ndi chinthu chotchingira moto chokhala ndi magetsi abwino komanso mphamvu zamakina apamwamba. Amadziwika ndi kukhazikika kwake, kukana chinyezi komanso kupirira kutentha kwambiri.
Ma board olimba amapangidwa ndi zida zapamwamba kwambiri, kuwonetsetsa kuti amatha kupirira zovuta zomwe zimagwiritsidwa ntchito tsiku ndi tsiku komanso chilengedwe. Kukhazikika kwa PCB ndikofunikira kwambiri pakuchita kwake komanso moyo wautali, makamaka pamapulogalamu omwe amapindika ndikupindika mobwerezabwereza.

Kuphatikiza pa khalidwe lachinthu, kusankha zinthu zoyenera kuti zikhale zofunikira pakupanga ndikofunikanso.Kusankhidwa kwa zinthu kumadalira zinthu monga kutentha kwa ntchito, kusinthasintha ndi zofunikira zamakina, komanso kukhudzana ndi chinyezi ndi mankhwala omwe PCB angakumane nayo. Opanga amawunika mosamala zinthuzi ndikusankha zida zomwe zikugwirizana ndi izi, kuwonetsetsa kukhazikika kwa ma PCB okhazikika omwe amawagwiritsa ntchito.

Flexibility ndi Bend Radius:

Flex ndi bend radius ndizofunikira kwambiri pakupanga ndi kupanga PCB yokhazikika. Ma PCB awa amadziwika ndi kuthekera kwawo kopindika popanda kuwononga kapena kulephera, kuwapanga kukhala oyenera ntchito zomwe zimafuna kusinthasintha komanso kukhazikika.

Bend radius ndiye mtunda wocheperako womwe bolodi imatha kupindika popanda kuwononga zigawo zake kapena magwiridwe ake onse.Zimatsimikiziridwa ndi zinthu zingapo, kuphatikizapo zinthu zakuthupi za PCB, masanjidwe ndi mapangidwe a zigawo, ndi malo a kufufuza ndi vias. Kukonzekera koyenera kwa malo opindika ndikofunikira kuti tipewe kusweka kapena kung'ambika panthawi yopanga. Izi zimaphatikizapo kuwonetsetsa kuti bolodi ndi yayikulu ndikuyalidwa kuti igwirizane ndi kusinthasintha komwe kumayembekezeredwa kapena kusinthasintha popanda kusokoneza kukhulupirika kwa gawo. Komanso, kugwiritsa ntchito chitsulo chamkuwa m'dera lopindika kumathandizira kukulitsa kulimba kwa bolodi ndikupewa kuwonongeka. Kupanga kosasintha komanso njira zolumikizirana zolondola ndizofunikira kwambiri kuti ma PCB asasunthike mokhazikika ngakhale mutazungulira kangapo. Izi zikuphatikizanso chidwi chatsatanetsatane pakugulitsa, kuyika kwazinthu ndikutsata miyezo yamakampani ndi machitidwe abwino.

Ndikofunika kuzindikira kuti kulimba kwa matabwa olimba-flex kutha kusiyanasiyana malinga ndi ntchito yeniyeni.Mafakitale monga zakuthambo kapena azachipatala nthawi zambiri amafunikira kusinthasintha kosalekeza kapena kopitilira muyeso ndipo angafunike kuganizira mozama kwambiri kuti atsimikizire kudalirika komanso kulimba kwa nthawi yayitali. Zikatero, njira zowonjezera zitha kuchitidwa, monga kuwonjezera kulimbikitsa kwina m'malo ovuta kapena kusankha zida zokhala ndi zida zopindika.

Zachilengedwe:

Kukhalitsa kwa bolodi lolimba-flex kumadalira kwambiri mphamvu yake yolimbana ndi zinthu zachilengedwe monga kusintha kwa kutentha, chinyezi, ndi kugwedezeka - zonse zomwe zimachitika pazida zamagetsi.

Kutentha kwapang'onopang'ono ndi mayeso odalirika omwe amachitidwa pa ma PCB osasunthika kuti awone kukana kwawo kusinthasintha kwa kutentha kwambiri.Kupyolera mu mayeserowa, opanga amatha kuzindikira zofooka zomwe zingatheke pakupanga bolodi kapena kusankha zinthu zomwe zingayambitse kulephera pansi pa kutentha kwapadera.

Chinyezi chitha kukhudzanso kulimba kwa matabwa olimba. Kuti awonjezere kukana kwawo, opanga nthawi zambiri amapaka zokutira zapadera kapena zokutira zomwe zimapereka chitetezo chowonjezera.Zopaka izi zimalepheretsa kulowa kwa chinyezi ndikuteteza PCB kuti isachite dzimbiri, kukulitsa moyo wake.

Chinthu chinanso chofunikira cha chilengedwe chomwe chimakhudza kukhazikika kokhazikika ndikugwedezeka.Kugwedezeka kumatha kutsindika bolodi ndi zigawo zake, zomwe zimapangitsa kulephera kwa mgwirizano wa solder kapena chigawo chapakati. Pofuna kuchepetsa zotsatira za kugwedezeka, opanga angagwiritse ntchito njira monga nthiti, zomatira kapena makina okwera kuti ateteze zigawo zikuluzikulu ndi kuchepetsa zotsatira za kugwedezeka.

Kuphatikiza apo, fumbi, dothi, ndi zonyansa zina zimatha kukhudza magwiridwe antchito komanso moyo wautali wa ma board okhazikika.Ngati zonyansazi zayikidwa pamwamba pa bolodi lozungulira, zingayambitse mabwalo afupikitsa, dzimbiri kapena kuwonongeka kwa insulation. Kusindikiza koyenera ndi kuteteza matabwa ozungulira, komanso kuyeretsa ndi kukonza nthawi zonse, n'kofunika kwambiri kuti tipewe mavutowa.

Kuphatikiza apo, electromagnetic interference (EMI) imatha kukhudza magwiridwe antchito a ma rigid-flex board, makamaka pamapulogalamu omwe zida zodziwika bwino kapena ma siginecha apamwamba amapezeka.Njira zotetezera monga ndege zapansi kapena zokutira zotetezera zimathandiza kuchepetsa EMI ndikuwonetsetsa kukhulupirika kwa kufalitsa chizindikiro pa bolodi.

Zotsatira za mphamvu zakunja (monga momwe zimakhudzira kapena kukhudzidwa) pamagulu olimba osinthasintha ziyeneranso kuganiziridwa.Zida zomwe zimagwiridwa mwankhanza kapena zoyendera zitha kuonongeka. Chifukwa chake, kulongedza moyenera, zida zowononga mantha, ndi zotchingira zoteteza ndizofunikira kuti bolodi ikhale yolimba.

Kapangidwe kagawo ndi Trace:

Chigawo ndi kutsata masanjidwe pa bolodi lolimba-flex ndizofunikira kuti zitsimikizire kulimba kwake.Mbali imodzi yofunika kuiganizira ndi gawo losinthika la bolodi. Ma board olimba amapangidwa kuti azipinda ndi kupindika, koma kupindika mopitilira muyeso m'malo ena kumatha kuyika kupsinjika kopitilira muyeso pazinthu zomwe zimatsogolera kulephera kwamakina. Pokonzekera mosamala zigawo, okonza akhoza kuchepetsa chiopsezo cha kupsinjika kwa makina kapena kuwonongeka.

Zida ziyenera kusungidwa kutali ndi malo omwe kupindika kwakukulu kumachitika.Kuwayika pamalo olimba kapena okhazikika a bolodi kungathandize kuwateteza ku nkhawa zosafunikira. Komanso, ndikofunikira kulingalira kukula ndi kulemera kwa zigawozo. Zigawo zazikulu kapena zolemera ziyenera kuikidwa m'madera omwe sangakhale ndi kusinthasintha kwakukulu.

Kufufuza ndi vias ndi conductive njira pa bolodi kuti nawonso ayenera kuikidwa njira.Ayenera kuikidwa m'malo omwe sangakhale opanikizika kwambiri. Popewa madera opindika ovuta, mumachepetsa chiopsezo cha kuwonongeka kwa trace komanso kuthekera kotsegula kapena zazifupi.

Kuti muwonjezere kulimba kwa mapanelo, zomatira zitha kugwiritsidwa ntchito kulumikiza ndi kulimbikitsa nthiti.Nthiti ndi timizere tating'ono tomwe timayika pakati pa plies kuti tithandizire. Pogwirizanitsa zigawo ndi zizindikiro ku nthitizi, luso lawo lotha kupirira kupindika ndi kupindika limakhala bwino. Zomatira zimagwira ntchito ngati chotchinga choteteza, kuchepetsa kuthekera kwa zinthu zowononga ndi kutsata panthawi yopindika.

Miyezo Yoyesera ndi Chitsimikizo:

Pankhani yoyesa ndi chiphaso, ma board a rigid-flex amadutsa njira zosiyanasiyana kuti awone kulimba kwawo komanso kudalirika kwawo. Mayeserowa ndi ofunikira kuti awonetsetse kuti gululo likukwaniritsa zofunikira zoyenera komanso machitidwe.

IPC-6013 ndi muyezo wofunikira womwe umawongolera kuyezetsa kosasunthika, kofalitsidwa ndi Printed Circuits Council (IPC).Muyezowu umapereka zofunikira ndi zofunikira pakuwunika ma board awa. Kutsatira IPC-6013 kumawonetsetsa kuti ma board akwaniritsa malangizo ovomerezeka ndi makampani kuti akhale abwino komanso olimba.

Kuyesa kosasunthika kumaphatikizapo kuyesa kwamakina ndi magetsi.Kuyesa kwamakina kumawunika kuthekera kwa gulu lozungulira kuti athe kupirira kupindika, kupindika, ndi zovuta zina zamakina zomwe zingakumane nazo pa moyo wake wothandiza. Mayesowa angaphatikizepo kupinda, kupindika ndi kugwedeza bolodi kuti ayesere zochitika zenizeni padziko lapansi. Yesani kukana kwa bolodi ku zovuta izi ndikulemba zolephera kapena kuwonongeka kulikonse.

Kuyesa kwamagetsi kumawunika momwe magetsi amagwirira ntchito komanso kukhulupirika kwa bolodi lokhazikika lokhazikika.Mayesowa angaphatikizepo kuyang'ana zotseguka, zazifupi, miyeso ya impedance, kukhulupirika kwa ma siginecha, ndi kuyesa kwamagetsi/pano. Poyesa magetsi awa, zitha kudziwika kuti bolodi imakwaniritsa zofunikira zamagetsi ndipo ikugwira ntchito moyenera.

Kuphatikiza pakuyesa kwamakina ndi magetsi, mayeso ena amatha kuchitidwa kuti awunike mawonekedwe kapena zofunikira zama board okhazikika.Izi zitha kuphatikizira kuyesa magwiridwe antchito amafuta, kuchedwa kwamoto, kukana mankhwala, kukana chinyezi komanso kudalirika pansi pazovuta zachilengedwe.

Chitsimikizo ndi gawo lofunikira pakuyesa kokhazikika.Ma board akapambana mayeso onse ofunikira, amatha kutsimikiziridwa kuti akugwirizana ndi zomwe zafotokozedwa mu IPC-6013 kapena miyezo ina yamakampani. Chitsimikizochi chimatsimikizira makasitomala ndi ogwiritsa ntchito kuti bolodi ndi yapamwamba, yodalirika komanso yolimba.
Kukhazikika kwa matabwa okhazikika a PCB ndi chifukwa cha kapangidwe kake, kusankha zinthu, ndi malingaliro opanga.Pogwiritsa ntchito zipangizo zamtengo wapatali, kugwiritsa ntchito njira zoyenera zosinthira, kuthana ndi zovuta zachilengedwe, ndikuyika mwadongosolo zigawo ndi zizindikiro, opanga amatha kuonetsetsa kuti matabwawa akwaniritsa zofunikira za ntchito zosiyanasiyana. Ngakhale ma PCB osasunthika amapereka kukhazikika kwapadera, ndikofunikira kugwira ntchito ndi opanga odziwa komanso opanga kuti muwonetsetse kuti zofunikira pa pulogalamu iliyonse zikukwaniritsidwa. Potsatira miyezo yamakampani ndikuyesa mozama, opanga amatha kutsimikizira kuti ma PCB awo okhazikika okhazikika adzakhala ndi kulimba komanso moyo wautali wofunikira pazida zamakono zamakono.
