Delamination mu PCB imatha kubweretsa zovuta zogwira ntchito, makamaka pamapangidwe okhazikika pomwe zida zolimba komanso zosinthika zimaphatikizidwa. Kumvetsetsa momwe mungapewere delamination ndikofunikira kuti muwonetsetse kuti nthawi yayitali komanso yodalirika yamisonkhano yovutayi. Nkhaniyi tikambirana malangizo othandiza kupewa PCB delamination, kuganizira PCB lamination, ngakhale zinthu, ndi wokometsedwa Machining magawo.
Kumvetsetsa PCB Delamination
Delamination imachitika pamene zigawo za PCB zimasiyana chifukwa cha zinthu zosiyanasiyana, kuphatikizapo kupsinjika kwa kutentha, kuyamwa kwa chinyezi, ndi zovuta zamakina. M'ma PCB osasunthika, zovuta zimakula chifukwa chamitundu yosiyanasiyana yazinthu zolimba komanso zosinthika. Chifukwa chake, kuwonetsetsa kuyanjana pakati pazidazi ndi gawo loyamba popewa delamination.
Onetsetsani PCB Material Kugwirizana
Kusankha kwazinthu ndizofunikira kwambiri popewa delamination. Mukamapanga PCB yokhazikika, ndikofunikira kusankha zida zomwe zili ndi ma coefficients owonjezera amafuta. Kugwirizana kumeneku kumachepetsa kupsinjika panthawi yothamanga njinga, zomwe zingayambitse delamination. Komanso, ganizirani zomatira zomwe zimagwiritsidwa ntchito popanga lamination. Zomatira zapamwamba kwambiri zomwe zimapangidwira kuti zigwiritsidwe ntchito mokhazikika zimatha kukulitsa kwambiri mphamvu ya mgwirizano pakati pa zigawo.
Njira ya PCB Lamination
Njira yopangira lamination ndi gawo lofunikira kwambiri popanga PCB. Lamination yoyenera imatsimikizira kuti zigawozo zimagwirizana bwino, kuchepetsa chiopsezo cha delamination. Nawa malangizo othandiza a PCB lamination:
Kutentha ndi Kuwongolera Kupanikizika: Onetsetsani kuti njira yopangira lamination ikuchitika pa kutentha koyenera ndi kupanikizika. Kutentha kwambiri kumatha kuwononga zida, pomwe kupanikizika kosakwanira kungayambitse kusamata bwino.
Vacuum Lamination: Kugwiritsa ntchito vacuum panthawi ya lamination kungathandize kuthetsa thovu la mpweya lomwe lingayambitse mawanga ofooka mu mgwirizano. Njirayi imatsimikizira kukakamiza kofananako pamagawo onse a PCB.
Nthawi Yokonzekera: Lolani nthawi yokwanira yochiritsa kuti zomatira zigwirizane bwino. Kuthamangira njirayi kungayambitse kumamatira kosakwanira, kuonjezera chiopsezo cha delamination.
Wokometsedwa Rigid-Flex PCB Machining Parameters
Machining magawo amatenga gawo lalikulu mu kukhulupirika kwa ma PCB okhazikika. Nawa maupangiri okhathamiritsa makina kuti mupewe delamination:
Njira Zobowola: Gwiritsani ntchito zobowola zoyenera ndi kuthamanga kuti muchepetse kutentha kwanthawi yayitali pobowola. Kutentha kwambiri kumatha kufooketsa chomangira chomata ndikuyambitsa delamination.
Njira ndi Kudula: Mukamayendetsa kapena kudula PCB, onetsetsani kuti zida zake ndi zakuthwa komanso zosamalidwa bwino. Zida zopepuka zimatha kuyambitsa kupanikizika kwambiri ndi kutentha, kusokoneza kukhulupirika kwa zigawo.
Chithandizo cha Edge: Kusamalira bwino m'mbali mwa PCB pambuyo Machining. Izi zitha kuphatikizira kusalaza kapena kusindikiza m'mbali kuti chinyontho chisalowe, chomwe chingathandize kuti delamination pakapita nthawi.
Malangizo Othandiza Popewa PCB Delamination
Kuwonjezera pa njira zomwe zili pamwambazi, ganizirani malangizo othandiza awa:
Kuwongolera Zachilengedwe: Sungani ma PCB pamalo olamulidwa kuti mupewe kuyamwa kwa chinyezi. Chinyezi chimafooketsa chomangira chomata ndikupangitsa kuti delamination.
Kuyesedwa Kwanthawi Zonse: Khazikitsani kuyezetsa pafupipafupi kwa ma PCB pazizindikiro za delamination panthawi yopanga. Kuzindikira msanga kungathandize kuchepetsa mavuto asanakule.
Maphunziro ndi Chidziwitso: Onetsetsani kuti onse ogwira nawo ntchito pakupanga PCB amaphunzitsidwa njira zabwino zopangira lamination ndi makina. Kuzindikira zinthu zomwe zimapangitsa kuti delamination ikhale yabwino.
