4 Layer ENIG FR4 Heavy Copper PCB
Heavy Copper PCB
Heavy copper PCB board akhoza kupangidwa mophweka mwa kuphatikiza njira ziwiri zazikulu, electroplating ndi etching.Mosiyana ndi ma PCBS ena, derali limapangidwa ndi chojambula chopyapyala chamkuwa.
Ma PCB amkuwa olemera amapangidwa mofanana ndi FR4 kapena zinthu zina za epoxy.Kulemera kwapakati kwa PCB zamkuwa zolemera zimatha kukhala ma ounces 4 (140μm), zomwe ndi chiŵerengero chabwinoko kuposa PCB ina yamkuwa wamba.
Kuchuluka kwa mkuwa wowonjezera kumapangitsa kuti bolodi liziyendetsa mafunde apamwamba, kukwaniritsa kutentha kwabwino, ndikupangitsa kusintha kosavuta pamalo ochepa.Ubwino wina ndikuwonjezera mphamvu zamakina pamalo olumikizirana, kuthekera kopanga miyeso yaying'ono yazinthu pophatikiza zolemera zingapo mugawo lomwelo la dera, komanso kutha kugwiritsa ntchito zida zapadera zokhala ndi chiopsezo chochepa cha kulephera kwa dera.
Ubwino Wa Heavy Copper PCB
Kupanga olemera mkuwa PCBs kumafuna ntchito plating kapena etching, monga kumawonjezera makulidwe a PCB mkuwa mbali makoma ndi mabowo plating.Kuphatikiza apo, PCBS yamkuwa yolemera imapangidwa ndi electroplated panthawi yopanga PCB.Izi zimathandiza kukulitsa khoma la PTH pa PCB.Makhalidwe ena a PCBS yamkuwa wandiweyani omwe amasiyana ndi ma PCBS ena ndi awa:
Kulemera kwa Copper:
Izi ndithudi mbali yaikulu ya lolemera mkuwa PCB.Amatanthawuza kulemera kwa mkuwa womwe umagwiritsidwa ntchito pa phazi limodzi mu ma ounces.
Chophimba
Chojambula chakunja chamkuwa.Kulemera kwa mkuwa kwa wosanjikiza wakunja ndi ndondomeko yokhazikika yokhazikitsidwa pasadakhale.
Gulu Lamkati
Ubwino wamkuwa ndi makulidwe a dielectric amkati mwawo ndi zinthu zomwe zafotokozedwa kale.Komabe, zitha kusinthidwa kuti zigwirizane ndi zosowa za polojekitiyi.
Kugwiritsa Ntchito Heavy Copper PCB
Ma PCB amkuwa olemera amagwiritsidwa ntchito m'njira zosiyanasiyana, monga zosinthira lathyathyathya, kufalitsa kutentha, kubalalitsidwa kwamphamvu kwambiri, otembenuza owongolera, ndi zina zambiri. Mu PC, magalimoto, zida zankhondo ndi makina owongolera, chidwi cha mbale zodzaza ndi mkuwa chikukula.Ma board ozungulira amkuwa olemera amkuwa amagwiritsidwanso ntchito kwambiri:
1. Mphamvu zamagetsi ndi zowongolera zowongolera
2. Ulamuliro wa ndalama
3. Zida zowotcherera kapena zida
4. Makampani opanga magalimoto
5. Opanga solar panel, etc
