Kufunika kwa Stiffeners mu 2-Layer Flexible PCB Stackup

Tsegulani:

Flexible printed circuit boards (PCBs) asintha makampani opanga zamagetsi popangitsa kuti pakhale mapangidwe osavuta komanso osinthika. Amapereka maubwino ambiri kuposa anzawo olimba, monga kuwongolera kwapamwamba kwamafuta, kuchepetsa kulemera ndi kukula, komanso kudalirika kodalirika. Komabe, zikafika pa 2-layer flexible PCB stack-ups, kuphatikizidwa kwa ouma kumakhala kovuta.Mubulogu iyi, tiwona chifukwa chake ma 2-layer flexible PCB stackups amafunikira zolimba ndikukambirana zakufunika kwawo pakuwonetsetsa kuti akugwira ntchito bwino komanso kukhala ndi moyo wautali.

Phunzirani za kusinthika kwa PCB:

Tisanafufuze kufunikira kwa zolimba, choyamba tiyenera kumvetsetsa bwino lomwe kusinthika kwa PCB. Kusintha kwa PCB kumatanthawuza dongosolo linalake la zigawo zingapo mu bolodi yosinthasintha. Mu 2-wosanjikiza stackup, a flexible PCB imakhala ndi zigawo ziwiri zamkuwa zosiyanitsidwa ndi flexible insulating material (nthawi zambiri polyimide).

Chifukwa chiyani 2-layer flexible PCB stackup ikufunika zowuma?

1. Thandizo lamakina:

Chimodzi mwazifukwa zazikulu zomwe ma stiffeners amafunikira mu 2-layer flexible PCB stackup ndikupereka chithandizo chamakina. Mosiyana ndi ma PCB okhwima, ma PCB osinthika alibe kukhazikika kwawo. Kuwonjezera zowuma kumathandizira kulimbitsa kapangidwe kake ndikuletsa PCB kuti isapindike kapena kupindika panthawi yogwira kapena kusonkhana. Izi zimakhala zofunikira makamaka ngati ma PCB osinthika nthawi zambiri amapindika kapena kupindidwa.

2. Limbikitsani bata:

Nthiti zimagwira ntchito yofunikira pakukulitsa kukhazikika kwa 2-layer flexible PCB stack-up. Popereka kukhazikika kwa PCB, amathandizira kuchepetsa kuthekera kwa zovuta zoyambitsa kugwedezeka, monga resonance, zomwe zitha kusokoneza magwiridwe antchito onse ndi kudalirika kwa dera. Kuonjezera apo, zowuma zimalola kugwirizanitsa bwino ndi kulembetsa panthawi ya msonkhano, kuwonetsetsa kuti zigawozo zili bwino komanso zimagwirizanitsa.

3. Thandizo lazinthu:

Chifukwa china chofunikira chomwe ma 2-layer flex PCB stackups amafunikira stiffeners ndikupereka chithandizo chazigawo. Zida zambiri zamagetsi zimafunikira zida zaukadaulo wapamtunda (SMT) kuti zikhazikitsidwe pa ma PCB osinthika. Kukhalapo kwa zowuma kumathandizira kufalitsa kupsinjika kwamakina komwe kumachitika panthawi ya soldering, kuteteza kuwonongeka kwa zigawo zolondola ndikuwonetsetsa kulondola kwawo pagawo losinthika.

4. Kutetezedwa kuzinthu zachilengedwe:

Ma PCB osinthika nthawi zambiri amagwiritsidwa ntchito pazinthu zomwe zimakumana ndi zovuta zachilengedwe, monga kutentha kwambiri, chinyezi, kapena kukhudzidwa ndi mankhwala. Nthitizi zimakhala ngati chotchinga choteteza, kuteteza madera osalimba kuti asawonongeke chifukwa cha zinthu zachilengedwezi. Kuonjezera apo, amathandizira kusintha kukana kwa PCB kosinthika ku zovuta zamakina ndikuletsa kulowetsa chinyezi, potero kumawonjezera moyo wautali komanso kudalirika.

5. Njira ndi Kukhulupirika kwa Chizindikiro:

Mu 2-layer flex PCB stackup, ma siginecha ndi ma track amphamvu nthawi zambiri amayendera mkati mwa bolodi yosinthira. Nthiti zilipo kuti zisunge malo oyenera komanso kupewa kusokoneza magetsi pakati pa zigawo zamkuwa zamkati. Kuphatikiza apo, zowuma zimateteza ma siginecha othamanga kwambiri kuchokera ku crosstalk ndi kutsika kwa ma sign, kuwonetsetsa kuti kuwongolera kumayendetsedwa ndikusunga kukhulupirika kwa ma siginecha.

Pomaliza:

Mwachidule, zouma ndi gawo lofunikira mu 2-layer flexible PCB stack-up pamene amathandizira popereka chithandizo chamakina, kupititsa patsogolo kukhazikika, kupereka chithandizo chamagulu, ndi kuteteza kuzinthu zachilengedwe.Amateteza mabwalo olondola, amasunga kukhulupirika kwazizindikiro, ndikulola kusonkhana bwino komanso kugwira ntchito modalirika pamagwiritsidwe osiyanasiyana. Mwa kuphatikiza zolimba mu mapangidwe osinthika a PCB, mainjiniya amatha kuwonetsetsa kulimba komanso moyo wautali wa zida zawo zamagetsi pomwe akusangalala ndi mabwalo osinthika.
