Hana ʻia ʻo HDI PCB i kahi hale hana PCB automated --- ENEPIG PCB hoʻopau ʻili
ʻO ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold) ʻaʻole ia he PCB maʻamau i hoʻohana ʻia i kēia manawa ʻoiai ua lilo i mea kaulana i ka ʻoihana hana PCB.Ua pili ia no ka laulā o ka noi e laʻa, nā ʻāpana ʻili like ʻole a me nā papa PCB kiʻekiʻe loa.ʻO ENEPIG kahi mana hou o ENIG, me ka hoʻohui ʻana i kahi papa Palladium (0.1-0.5 µm/4 a i 20 μ'') ma waena o Nickel (3-6 µm/120 – 240 μ'') a me ke gula (0,02- 0,05 µm/1 i ka 2 μ'') ma o ke kaʻina hana kemika immersion ma ka hale hana PCB.Hana ʻia ka palladium ma ke ʻano he pale e pale i ka papa nickel mai ka corrosion e Au, e kōkua i ka pale ʻana i ka "papa ʻeleʻele" mai ka puka ʻana mai kahi pilikia nui no ENIG.
Inā ʻaʻohe hoʻopaʻa kālā, ʻoi aku ka maikaʻi o ka ENEPIG i ka hapa nui o nā kūlana ʻoi aku ka nui o nā koi koi nui me nā ʻano pūʻolo lehulehu e like me, through-holes, SMT, BGA, wire bonding, a press fit, ke hoʻohālikelike ʻia me ENIG.
Eia kekahi, ʻoi aku ka maikaʻi o ka lōʻihi a me ke kūpaʻa ʻana i ke ola lōʻihi.He mea maʻalahi a hilinaʻi hoʻi i ka hoʻokomo ʻana i nā ʻāpana a me ke kūʻai ʻana.Eia kekahi, hāʻawi ʻo ENEPIG i kahi koho Wire Bonding hilinaʻi kiʻekiʻe.
Pono:
• maʻalahi e hana
• ʻEleʻele Pad Free
• ili palahalaha
• ʻOi aku ka maikaʻi o ka mālama ʻana (12 mahina+)
• ʻAe ʻia nā pōʻaiapili reflow he nui
• Nui no ka Plated through Holes
• Nui no ka Pitch maikaʻi / BGA / Nā mea liʻiliʻi
• Maikaʻi no ka Hoʻopā Hoʻopā / Hoʻokaʻa Push
• ʻOi aku ka hilinaʻi ʻoi aku ka maikaʻi o ka hoʻopaʻa uea (gula / aluminika) ma mua o ENIG
• ʻOi aku ka ikaika o ka Solder hilinaʻi ma mua o ENIG;Hoʻokumu i nā hui solder hilinaʻi Ni/Sn
• Hoʻohālikelike loa me nā mea kūʻai aku Sn-Ag-Cu
• Nānā maʻalahi
Cons:
• ʻAʻole hiki i nā mea hana a pau ke hāʻawi.
• Pono ka pulu no ka lōʻihi lōʻihi.
• ʻO ke kumukūʻai kiʻekiʻe
• Hoʻopili ʻia ka maikaʻi e nā kūlana plating
• ʻAʻole paha e like me ka hilinaʻi no ka hoʻopaʻa uea gula ke hoʻohālikelike ʻia me ke gula palupalu
Hoʻohana maʻamau:
ʻO nā Hui Kūʻai Kiʻekiʻe, ʻenehana paʻakikī a hui pū paha, nā mea hana kiʻekiʻe, noi hoʻopaʻa uea, nā PCB lawe IC, etc.
