Kodi nthawi ya moyo wa rigid flex PCB circuit ndi chiyani?

Mawu Oyamba

Mu positi iyi yabulogu, tikufuna kuwulula zinsinsi za moyo wa ma PCB apaderawa ndikuwunikira zomwe zimakhudza moyo wawo wautali.

Zikafika ku dziko losindikizidwa dera (PCB), imodzi mwa mitundu yosangalatsa kwambiri ndi PCB yokhazikika. Ma board awa amaphatikiza kusinthasintha kwa ma PCB osinthika ndi kukhazikika kwa ma PCB okhwima ndipo akukhala otchuka kwambiri m'mafakitale osiyanasiyana. Komabe, funso limodzi lomwe limabuka ndilakuti: "Kodi ma board olimba amatalika bwanji?"

Kumvetsetsa ma board a rigid-flex

Tisanamvetsetse moyo wautumiki wa ma rigid-flex board, choyamba timvetsetse zomwe iwo ali. Ma PCB osasunthika ndi ma board ozungulira omwe amapangidwa ndi madera okhazikika komanso osinthika omwe amathandizira kupanga zinthu zambiri. Kuphatikizana kwa kuuma ndi kusinthasintha kumatheka pogwiritsa ntchito zinthu zolimba komanso zosinthika monga FR4 ndi polyimide. Ma board a Rigid-flex amapereka maubwino angapo, kuphatikiza kuchepetsedwa kwa nthawi yolumikizirana ndi malo, kudalirika kokhazikika, komanso kulimba kolimba.

Zinthu zomwe zimakhudza nthawi ya moyo

Poganizira za moyo wautumiki wa ma rigid-flex board, zinthu zingapo zimachitika. Ngakhale kuti matabwawa amapangidwa kuti azikhala olimba, zinthu zina zingakhudze moyo wawo wautali. Tiyeni tiwone mwatsatanetsatane zina mwazinthu zazikulu zomwe zimakhudza moyo wa board-flex board:

1. Mikhalidwe yogwirira ntchito: Mikhalidwe yogwirira ntchito yomwe gulu lolimba-flex likuwonekera limakhudza kwambiri moyo wake wautumiki. Zinthu monga kutentha, chinyezi ndi kugwedezeka, zonse zimagwira ntchito. Kutentha kwambiri kapena chinyezi chambiri kumatha kutsindika zakuthupi, zomwe zitha kupangitsa kuti delamination kapena kulephera msanga. Momwemonso, kugwedezeka kwakukulu kungayambitse kutopa kumalo osinthasintha, kumabweretsa ming'alu kapena kulephera kwa magetsi.

2. Kusankha Zinthu: Zida zomwe zimagwiritsidwa ntchito pomanga okhwima a PCB zimagwira ntchito yofunika kwambiri pozindikira moyo wake wautumiki. Zida zamtengo wapatali zokhala ndi makina abwino kwambiri komanso kutentha ndizofunikira kuti zitsimikizire kuti zikugwira ntchito kwa nthawi yayitali. Kusankha zinthu zomwe zimatsutsana bwino ndi kutentha, mankhwala ndi zinthu zachilengedwe zimatha kupititsa patsogolo kulimba kwa bolodi.

3. Zolinga za mapangidwe: Mapangidwe a matabwa olimba-flex amakhudzanso mwachindunji moyo wawo. Kukonzekera koyenera, kukonzekera kwa stacking ndi kuika zigawo ndizofunikira kuti zitsimikizire kugawa bwino kwa nkhawa komanso kuchepetsa chiopsezo cha kulephera. Kusakhazikika bwino kapena kusanjika bwino kungayambitse kupsinjika kosafunikira komwe kumayambitsa kuwonongeka msanga kwa bolodi.

4. Njira yopangira: Njira yopangira yokha idzakhudza moyo wautumiki wa bolodi lokhazikika. Kuwongolera bwino komanso kuwongolera bwino pakupanga, kuphatikiza njira zoyenera zolumikizirana ndi zomangira, ndizofunikira kwambiri kuti tipewe zolakwika zomwe zingasokoneze kukhulupirika kwa gulu ladera. Kuonjezera apo, kusamalira bwino ndi kusungirako panthawi yopanga ndi kusonkhanitsa n'kofunikanso kuti tipewe kuwonongeka komwe kungakhudze moyo wautumiki.

Mapeto

Mwachidule, moyo wautumiki wa ma rigid-flex board umakhudzidwa ndi zinthu zosiyanasiyana, kuphatikiza momwe magwiridwe antchito, kusankha kwazinthu, malingaliro apangidwe, ndi njira zopangira. Pomvetsetsa izi ndikuziganizira panthawi yopangira ndi kupanga, moyo wautumiki wa ma board-flex board ukhoza kukonzedwa. Kutsatira miyezo yamakampani ndikugwira ntchito ndi wopanga PCB wodziwa bwino kumatha kusintha kwambiri magwiridwe antchito komanso kudalirika kwa matabwa osunthikawa. Chifukwa chake, poganizira za moyo wautumiki wa bolodi lokhazikika, kumbukirani kuti PCB yopangidwa bwino, yopangidwa bwino yophatikizidwa ndi magwiridwe antchito abwino kwambiri imatha kukulitsa kulimba kwake komanso moyo wonse.
