Kodi heavy copper PCB ndi chiyani?

Mtundu wa PCB uwu ndi chisankho choyamba pamene mafunde apamwamba sangalephereke: PCB yamkuwa wandiweyani , yopangidwa muukadaulo weniweni wa etching. Ma PCB amkuwa okhuthala amadziwika ndi mapangidwe okhala ndi makulidwe amkuwa kuyambira 105 mpaka 400 µm. Ma PCB awa amagwiritsidwa ntchito pazotulutsa zazikulu (zapamwamba) komanso kukhathamiritsa kasamalidwe ka matenthedwe. Mkuwa wandiweyani umalola magawo akulu a PCB-mtanda kuti azinyamula katundu wambiri komanso amalimbikitsa kutentha. Mapangidwe omwe amadziwika kwambiri ndi multilayer kapena awiri-mbali. 

Ngakhale kuti palibe tanthawuzo lodziwika bwino la Heavy Copper, nthawi zambiri amavomereza kuti ngati ma ounces atatu (oz) amkuwa kapena ochulukirapo akugwiritsidwa ntchito pamagulu amkati ndi akunja a bolodi losindikizidwa, amatchedwa PCB yamkuwa wolemera . Dera lililonse lokhala ndi makulidwe amkuwa opitilira 4 oz pa phazi lalikulu (ft2) limagawidwanso ngati PCB yamkuwa yolemera. Mkuwa wochuluka umatanthauza 20 oz pa ft2 mpaka 200 oz pa ft2.

PCB yamkuwa yolemera imadziwika kuti ndi PCB yokhala ndi makulidwe a 3 oz pa ft2 mpaka 10 oz pa ft2 mu zigawo zakunja ndi zamkati. PCB yamkuwa yolemera imapangidwa ndi zolemera zamkuwa kuyambira 4 oz pa ft2 mpaka 20 oz pa ft2. Kulemera kwa mkuwa wowongoka bwino, pamodzi ndi plating yokhuthala ndi gawo lapansi loyenera m'mabowo amatha kusintha bolodi lofooka kukhala nsanja yayitali komanso yodalirika yolumikizira. Makondakitala amkuwa olemera amatha kukulitsa makulidwe onse a PCB kwambiri. Kuchuluka kwa mkuwa kuyenera kuganiziridwa nthawi zonse panthawi yopanga dera. Mphamvu yonyamula pakali pano imatsimikiziridwa kuchokera m'lifupi ndi makulidwe a mkuwa wolemera.

Phindu lalikulu la matabwa ozungulira amkuwa ndi kuthekera kwawo kuti apulumuke nthawi zambiri, kutentha kwanthawi yayitali komanso kuthamanga kwapang'onopang'ono, komwe kumatha kuwononga bolodi lokhazikika mumasekondi. Bolodi lamkuwa lolemera kwambiri limakhala ndi kulekerera kwakukulu, zomwe zimapangitsa kuti zigwirizane ndi ntchito muzochitika zovuta monga, chitetezo ndi malonda a ndege.

Zina mwazabwino zowonjezera za matabwa olemera amkuwa ndi awa:

Kukula kwazinthu zophatikizika chifukwa cha zolemera zingapo zamkuwa pagawo limodzi lozungulira

Njira zokulirapo zamkuwa zimadutsa mulingo wokwezeka kudzera pa PCB ndikuthandizira kusamutsa kutentha ku sinki yakunja ya kutentha.

Kusiyana pakati pa Standard PCB ndi Thick Copper PCB

Ma PCB okhazikika amatha kupangidwa ndi ma etching amkuwa ndi plating. Ma PCB awa amakutidwa kuti awonjezere makulidwe amkuwa kundege, ma trace, PTHs, ndi pads. Kuchuluka kwa mkuwa wogwiritsidwa ntchito popanga ma PCB wamba ndi 1oz. Popanga PCB yamkuwa yolemera, kuchuluka kwa mkuwa komwe kumagwiritsidwa ntchito ndikokulirapo kuposa 3oz.

Kwa matabwa ozungulira, njira zowotchera zamkuwa ndi plating zimagwiritsidwa ntchito. Komabe, ma PCB amkuwa olemera amapangidwa kudzera munjira zosiyanasiyana komanso kuyika masitepe. Ma PCB okhazikika amagwira ntchito zopepuka pomwe matabwa olemera amkuwa amagwira ntchito zolemetsa.

Ma PCB okhazikika amayendetsa ma PCB otsika pomwe ma PCB amkuwa olemera amayendetsa kwambiri pano. Ma PCB amkuwa okhuthala ndi abwino kwa mapulogalamu apamwamba chifukwa cha kugawa kwawo bwino kwamafuta. Ma PCB amkuwa olemera amakhala ndi mphamvu zamakina kuposa ma PCB wamba. Ma board olemera amkuwa amawonjezera luso la bolodi momwe amagwiritsidwira ntchito.

Zina zomwe zimapanga ma PCB amkuwa wandiweyani kusiyana ndi ma PCB ena

Kulemera kwa mkuwa: Ichi ndiye chosiyanitsa chachikulu cha PCB zamkuwa zolemera. Kulemera kwa mkuwa kumatanthawuza kulemera kwa mkuwa womwe umagwiritsidwa ntchito pamtunda wautali. Kulemera kumeneku nthawi zambiri kumayesedwa mu ma ounces. Zimasonyeza makulidwe a mkuwa pa wosanjikiza.

Zigawo zakunja: Izi zikutanthauza zigawo zamkuwa zakunja za bolodi. Zida zamagetsi nthawi zambiri zimagwirizanitsidwa ndi zigawo zakunja. Zigawo zakunja zimayamba ndi zojambula zamkuwa zomwe zimakutidwa ndi mkuwa. Izi zimathandiza kuwonjezera makulidwe. Kulemera kwa mkuwa kwa zigawo zakunja kumakonzedweratu kuti zikhale zokhazikika. Wolemera wamkuwa wa PCB amatha kusintha kulemera ndi makulidwe a mkuwa kuti agwirizane ndi zomwe mukufuna.

Zigawo zamkati: Makulidwe a dielectric, komanso kuchuluka kwa mkuwa kwa zigawo zamkati, zimatanthauziridwa pama projekiti okhazikika. Komabe, kulemera kwa mkuwa ndi makulidwe mu zigawozi zikhoza kusinthidwa malinga ndi zosowa zanu.

Ma PCB amkuwa olemera amagwiritsidwa ntchito pazinthu zingapo monga mapulani osinthira, kutentha kwapang'onopang'ono, kugawa mphamvu zambiri, otembenuza mphamvu, ndi zina zambiri. Pali kuchuluka kwa matabwa ovala zamkuwa pamakompyuta, magalimoto, zida zankhondo, ndi mafakitale.

Ma board ozungulira amkuwa olemera kwambiri amagwiritsidwanso ntchito mu:

Zida zamagetsi, zosinthira mphamvu

Kugawa mphamvu
