Hoʻopuka kēia pepa i kekahi mau ʻōlelo a me nā wehewehe ʻoihana maʻamau no ka hana laina hui omīkini SMT.
1. PCBA
Pai 'ia ka Papa Kaapuni Board Assembly (PCBA) i ke ka'ina hana e hana 'ia ai na papa PCB, me na pa'i SMT pa'i, DIP plugins, ho'ā'o hana, a me ka Hui huahana pau.
2. Papa PCB
ʻO ka Papa Kaapuni Pai (PCB) he manawa pōkole no ka papa kaapuni paʻi, maʻamau i hoʻokaʻawale ʻia i ka papa hoʻokahi, ka papa pālua a me ka papa multi-layer.ʻO nā mea maʻamau i hoʻohana ʻia ʻo FR-4, resin, lole aniani a me ka substrate alumini.
3. Nā waihona Gerber
ʻO ka waihona Gerber ka mea nui e wehewehe i ka hōʻiliʻili o ka palapala palapala o ka PCB kiʻi (laina laina, solder resistance layer, character layer, etc.) drilling and milling ikepili, pono e hāʻawi ʻia i ka PCBA processing plant i ka wā i hana ʻia ai ka ʻōlelo a PCBA.
4. waihona BOM
ʻO ka faila BOM ka papa inoa o nā mea.ʻO nā mea hana a pau i hoʻohana ʻia i ka hana PCBA, me ka nui o nā mea a me ke ala kaʻina hana, ʻo ia ke kumu nui no ke kūʻai ʻana i nā mea.Ke ʻōlelo ʻia ka PCBA, pono e hāʻawi ʻia i ka mea kanu PCBA.
5. SMT
ʻO SMT ka pōkole o "Surface Mounted Technology", e pili ana i ke kaʻina hana o ka paʻi paʻi solder, nā ʻāpana pepa e kau ana areflow umukūʻai ma ka papa PCB.
6. Paʻi paʻi solder
ʻO ka paʻi paʻi solder he hana ia e kau ai i ka paʻi solder ma ka ʻupena kila, e hoʻokuʻu i ka paʻi solder ma ka puka o ka ʻupena kila ma o ka ʻōpala, a paʻi pololei i ka paʻi solder ma ka papa PCB.
7. SPI
ʻO SPI kahi mea ʻike mānoanoa solder paste.Ma hope o ka paʻi ʻana i ka solder paste, pono ka ʻike SIP e ʻike i ke kūlana paʻi o ka solder paste a hoʻomalu i ka hopena paʻi o ka solder paste.
8. Reflow wiliwili
ʻO ka hoʻoulu hou ʻana e hoʻokomo i ka PCB i hoʻopaʻa ʻia i loko o ka mīkini solder reflow, a ma o ka wela kiʻekiʻe i loko, e hoʻomehana ʻia ka paʻi solder paste i loko o ka wai, a ma hope e hoʻopau ʻia ke kuʻi ʻana ma ka hoʻoluʻu a me ka paʻa.
9. AOI
ʻO AOI e pili ana i ka ʻike ʻike maka.Ma o ka hoʻohālikelike scanning, hiki ke ʻike ʻia ka hopena kuʻi ʻana o ka papa PCB, a hiki ke ʻike ʻia nā hemahema o ka papa PCB.
10. Hooponopono
ʻO ka hana o ka hoʻoponopono ʻana i ka AOI a i ʻole i ʻike lima ʻia nā papa hemahema.
11. DIP
He pōkole ʻo DIP no "Dual In-line Package", e pili ana i ka ʻenehana hana o ka hoʻokomo ʻana i nā ʻāpana me nā pine i loko o ka papa PCB, a laila hoʻomaʻamaʻa iā lākou ma o ke kūʻai ʻana i ka nalu, ka ʻoki wāwae, ke kūʻai aku ʻana, a me ka holoi ʻana i ka pā.
12. Ka nalu ʻana
Wave soldering mea e hookomo i ka PCB i loko o ka nalu soldering umu, ma hope o spray flux, preheating, nalu soldering, cooling a me nā loulou e hoʻopau i ka kuʻihao o ka PCB papa.
13. Eʻokiʻoki i nā mea
E ʻoki i nā ʻāpana ma ka papa PCB welded i ka nui kūpono.
14. Ma hope o ka hana kuʻi ʻana
Ma hope o ka hana kuʻi ʻana e hoʻoponopono i ka wili a hoʻoponopono i ka PCB ʻaʻole i hoʻopili piha ʻia ma hope o ka nānā ʻana.
15. Holoi papa
ʻO ka papa holoi holoi e hoʻomaʻemaʻe i ke koena o nā mea ʻino e like me ka flux ma nā huahana i hoʻopau ʻia o ka PCBA i mea e hoʻokō ai i ka maʻemaʻe maʻemaʻe maʻamau e koi ʻia e nā mea kūʻai.
16. ʻEkolu anti pena ka pulupulu
ʻEkolu ka hoʻopuʻi ʻana i ka pena kiʻi e hoʻopā i kahi papa o ka uhi kūikawā ma ka papa kumukūʻai PCBA.Ma hope o ka ho'ōla ʻana, hiki iā ia ke pāʻani i ka hana o ka insulation, moisture proof, leakage proof, shock proof, dust proof, corrosion proof, aging proof, mildew proof, nā ʻāpana wehe a me ka pale ʻana i ka corona.Hiki iā ia ke hoʻolōʻihi i ka manawa mālama o PCBA a hoʻokaʻawale i ka ʻino o waho a me ka pollution.
17. Pa'i wiliwili
E hoʻohuli i ka PCB i hoʻonui ʻia i nā alakaʻi kūloko, ʻaʻohe uhi pena insulation, hiki ke hoʻohana ʻia no nā ʻāpana wili.
18. Hoʻopili
ʻO ka Packaging e pili ana i ke ʻano o ka hoʻopili ʻana o nā ʻāpana, ua hoʻokaʻawale nui ʻia ka pahu i DIP pālua - laina a me SMD patch packaging ʻelua.
19. Hoʻokaʻawale pine
ʻO ka spacing pine e pili ana i ka mamao ma waena o nā laina waena o nā pine pili o ka mea kau.
20. QFP
He pōkole ʻo QFP no "Quad Flat Pack", e pili ana i kahi kaapuni i hui pū ʻia i ka ʻili i loko o kahi pūʻolo ʻilika lahilahi me nā alakaʻi airfoil pōkole ma nā ʻaoʻao ʻehā.
