Momwe mungathetsere vuto lamkuwa wonyezimira laminate wa PCB

Nawa ena mwa mavuto omwe gulu la PCB limakumana nawo komanso momwe mungatsimikizire. Vuto la PCB laminate likakumana, liyenera kuganiziridwa kuti liziwonjezera pamtundu wa PCB Laminate. Momwe mungathetsere vuto la mkuwa wovala laminate wa PCB?

PCB dera bolodi mkuwa wokutira laminate vuto i. Kuti athe kusaka

Ndizosatheka kupanga PCB iliyonse popanda kukumana ndi mavuto ena, makamaka chifukwa cha PCB yoluka laminate. Mavuto azikhalidwe akamachitika pakupanga kwenikweni, zimawoneka kuti gawo la PCB nthawi zambiri limayambitsa vutoli. Ngakhale cholembedwa mosamala ndikukhazikitsidwa mwatsatanetsatane wa ma laminates a PCB sichimatchula zinthu zoyeserera zomwe ziyenera kuchitidwa kuti zitsimikizire kuti ma laminates a PCB ndiomwe amayambitsa zovuta pakupanga. Nawa ena mwa mavuto odziwika bwino a PCB Laminate ndi momwe mungawatsimikizire.

Vuto la PCB laminate likakumana, liyenera kuganiziridwa kuti liziwonjezera pamtundu wa PCB Laminate. Nthawi zambiri, ukadaulo waukadaulowu ukapanda kupindulitsa, umapangitsa kusintha kosalekeza kwamtunduwu ndikupangitsa kuti zinthu zitheke. Nthawi zambiri, vuto lazinthu zakuthupi lomwe limayambitsidwa ndikusintha kwa mtundu wa Laminate wa PCB limapezeka muzogulitsidwa zopangidwa ndimagulu osiyanasiyana azinthu zopangira kapena katundu wosiyanasiyana. Ogwiritsa ntchito ochepa ndi omwe ali ndi zolemba zokwanira kusiyanitsa katundu wambiri kapena gulu lazinthu pamalo osakira. Chifukwa chake zimachitika kuti PCB imapangidwa pafupipafupi ndikuyika zida zake, ndipo warpage imapangidwa mosalekeza mu solder poyambira, yomwe imawononga ntchito zambiri komanso zotsika mtengo. Ngati nambala yotsitsa itha kupezeka nthawi yomweyo, wopanga wa Laminate wa PCB amatha kuwona kuchuluka kwa utomoni, zojambulazo zamkuwa, kuzungulira kozungulira, ndi zina zambiri. , wogwiritsa ntchitoyo adzavutika kwanthawi yayitali. Zotsatirazi zikufotokoza mavuto ambiri okhudzana ndi gawo lapansi pakupanga kwa PCB.

PCB dera bolodi zamkuwa zokutira laminate vuto 2. zinthu mopupuluma vuto

Zizindikiro: kumamatira kosavuta kwa zida zosindikizira, kulumikizana koyenera kwa zokutira, mbali zina sizingakhazikike, ndipo zina sizingagulitsidwe.

Njira zowunika: kuwunika kowonekera kumachitika nthawi zambiri ndikupanga zipsera zamadzi pamtunda:

Zomwe zingayambitse:

Chifukwa chakuda kwambiri komanso kosalala komwe kumachitika chifukwa cha kanema wowonongeka, mkuwa wosaphimbidwa ndi wowala kwambiri.

Kawirikawiri, wopanga laminate samachotsa womasulirayo pambali yopanda laminate.

Zikopa zopangira mkuwa zimapangitsa utomoni kutuluka ndikudziunjikira pamwamba pa zojambulazo zamkuwa, zomwe nthawi zambiri zimapezeka pamapepala amkuwa ochepa kuposa 3/4 oz kulemera kwake.

Opanga zojambulazo zamkuwa amagwiritsa ntchito ma antioxidants owonjezera pamwamba pa zojambulazo zamkuwa.

Opanga laminate asintha utomoni, amasula masamba, kapena njira zotsuka.

Chifukwa chosagwira bwino ntchito, pali zala zambiri kapena zipsera zamafuta.

Mafuta amathimbirira panthawi yokhomerera, kuphimba kapena kubowola.

Njira zothetsera mavuto:

Gwirizanani ndi wopanga laminate ndikufotokozerani zomwe amayesa mayeso asanasinthe chilichonse pakupanga laminate.

Ndikulimbikitsidwa kuti opanga laminate azigwiritsa ntchito nsalu ngati makanema kapena zida zina zotulutsira.

Lumikizanani ndi wopanga laminate kuti muwone gulu lililonse lazithunzi zamkuwa zomwe sizilephera kuyendera; Funsani yankho kuti muchotse utomoni woyenera.

Funsani wopanga laminate njira yochotsera. Nthawi zambiri amalimbikitsidwa kugwiritsa ntchito hydrochloric acid, kenako ndikuchotsa pomanga ndi kutsuka.

Lumikizanani ndi wopanga laminate kuti mugwiritse ntchito njira zopewera makina kapena mankhwala.

Phunzitsani onse ogwira ntchito kuti avale magolovesi ndikutenga zokutira zokutira zamkuwa. Onetsetsani ngati laminate ili yodzaza bwino kapena yodzaza m’thumba mukamanyamula, ndipo sulfa yomwe ili papepala ili yotsika, ndipo chikwama chonyamula chilibe dothi. Samalani kuti muwonetsetse kuti palibe amene angalumikizane ndi zojambulazo zamkuwa mukamagwiritsa ntchito sopo wokhala ndi silicone.

Chotsani ma laminates onse musanayale kapena kusintha mawonekedwe
