Heavy Copper PCB
Nthawi zambiri, makulidwe amkuwa a PCB yokhazikika ndi 1oz mpaka 3oz. Ma PCB okhuthala-mkuwa kapena ma PCB olemera-mkuwa ndi mitundu ya ma PCB omwe kulemera kwa mkuwa womalizidwa kumaposa 4oz (140μm) . Zopangidwe zofala kwambiri ndi multilayer kapena zapawiri. Ndi ukadaulo wa PCB uwu ndizothekanso kuphatikiza mapangidwe abwino pazigawo zakunja ndi zigawo zamkuwa wandiweyani mkati mwa zigawo zamkati.
PCB yokhuthala-mkuwa ndi ya mtundu wapadera wa PCB. zipangizo zake conductive, zipangizo gawo lapansi, ndondomeko kupanga, minda ntchito ndi osiyana PCBs ochiritsira. Kuyika kwa mabwalo akuda amkuwa kumathandizira opanga PCB kuti awonjezere kulemera kwa mkuwa kudzera m'mabowo am'mbali ndi maenje opakidwa, zomwe zimatha kuchepetsa kuchuluka kwa masanjidwe ndi mapazi. Kuyika kwa mkuwa wokhuthala kumaphatikiza mabwalo apamwamba komanso owongolera, kupanga kachulukidwe kakang'ono kokhala ndi ma board osavuta kutheka.
Kumanga
mabwalo
2.Kupirira kwapamwamba ku zovuta zotentha
3.Kutentha kwabwinoko
4.Kuwonjezera mphamvu zamakina pazitsulo ndi mabowo a PTH
5.Kuchepetsa kukula kwa mankhwala
Kugwiritsa ntchito ma PCB amkuwa wandiweyani
Pamodzi ndi kuchuluka kwa zinthu zamphamvu kwambiri, kufunikira kwa ma PCB amkuwa akuchulukirachulukira. Masiku ano opanga PCB amasamala kwambiri kugwiritsa ntchito bolodi lakuda lamkuwa kuti athetse kutentha kwamagetsi amagetsi apamwamba kwambiri.
Ma PCB okhuthala-mkuwa nthawi zambiri amakhala gawo lalikulu lapano, ndipo ma PCB akulu aposachedwa amagwiritsidwa ntchito kwambiri mugawo lamagetsi ndi zida zamagetsi zamagalimoto. Magalimoto achikhalidwe, magetsi, ndi zamagetsi zamagetsi amagwiritsa ntchito njira zoyambira zotumizira monga kugawa chingwe ndi pepala lachitsulo. Tsopano matabwa wandiweyani-mkuwa m'malo mawonekedwe kufala, amene osati kupititsa patsogolo zokolola ndi kuchepetsa nthawi mtengo wa mawaya, komanso kuonjezera kudalirika kwa zinthu zomaliza. Panthawi imodzimodziyo, matabwa akuluakulu amakono amatha kusintha mawonekedwe a mawaya, motero amazindikira miniaturization ya mankhwala onse.
Thick-copper circuit PCB imagwira ntchito yosasinthika pamapulogalamu omwe ali ndi mphamvu zambiri, zamakono, komanso kufunikira kozizira kwambiri. The kupanga ndondomeko ndi zipangizo za heavy-mkuwa PCBS ndi zofunika apamwamba kuposa PCBs muyezo. Ndi zida zapamwamba komanso mainjiniya akatswiri, YMS imapereka ma PCB amkuwa wandiweyani okhala ndi makasitomala apamwamba kwambiri ochokera kunyumba ndi kunja.
