HDI PCB ikora muruganda rwa PCB rwikora --- ENEPIG PCB kurangiza
ENEPIG (Electroless Nickel Electroless Palladium Immersion Zahabu) ntabwo ikoreshwa cyane kurangiza PCB kurubu mugihe imaze kumenyekana cyane mubikorwa byo gukora PCB.Irakoreshwa kumurongo mugari wa porogaramu eg, ibice bitandukanye byububiko hamwe nibibaho byateye imbere cyane PCB.ENEPIG ni verisiyo ivuguruye ya ENIG, hiyongereyeho Palladium (0.1-0.5 µm / 4 kugeza 20 μ '') hagati ya Nickel (3-6 µm / 120 - 240 μ '') na Zahabu (0,02- 0,05 µm / 1 kugeza 2 μ '') binyuze mumikorere yimiti yibiza muruganda rwa PCB.Palladium ikora nk'inzitizi yo kurinda urwego rwa nikel kwangirika na Au, ifasha gukumira "padi yumukara" kubaho bikaba ikibazo gikomeye kuri ENIG.
Niba nta guhuza ingengo yimari, ENEPIG isa nuburyo bwiza kubintu byinshi cyane cyane kubisabwa cyane cyane nibisabwa hamwe nubwoko bwinshi bwa paki nka, binyuze mu mwobo, SMT, BGA, guhuza insinga, no gukanda neza, mugihe ugereranije na ENIG.
Byongeye kandi, Kuramba no kwihanganira bihebuje bituma ubuzima buramba.Ikoti yoroheje yibiza ituma ibice bishyirwa hamwe no kugurisha byoroshye kandi byizewe.Mubyongeyeho, ENEPIG itanga uburyo bwizewe bwo gukoresha Wire Bonding.
Ibyiza:
• Biroroshye gutunganya
• Umukara wirabura
Ubuso bunini
• Ubuzima bwiza bwo kubaho neza (amezi 12 +)
• Kwemerera inzinguzingo nyinshi
• Nibyiza kubishyirwa mu mwobo
• Nibyiza kubibanza byiza / BGA / Ibice bito
• Nibyiza Kubikoraho / Gusunika
• Kwizirika hejuru kwizerwa (zahabu / aluminium) kuruta ENIG
• Kwizera gukomeye kugurishwa kuruta ENIG;Ifishi yizewe Ni / Sn igurisha ingingo
• Bihujwe cyane nabagurisha Sn-Ag-Cu
Kugenzura byoroshye
Ibibi:
• Ntabwo ababikora bose bashobora kubitanga.
• Amazi akenewe mugihe kirekire.
• Igiciro kinini
• Imikorere iterwa nuburyo bwo gufata amasahani
• Ntishobora kuba iyo kwizerwa muguhuza insinga za zahabu mugihe ugereranije na Zahabu yoroshye
Ibikoreshwa cyane:
Igiterane Cyinshi Cyinshi, Ikomatanyirizo cyangwa Ivanga rya Package Technologies, Ibikoresho Byiza cyane, Porogaramu Ihuza, Porogaramu itwara IC PC, nibindi.
