1. Electroless Nickel Immersion Gold (ENIG): Nke a bụ usoro ọgwụgwọ elu PCB nkịtị.Ọ na-agụnye itinye akwa nickel na-enweghị eletrọl dị ka oyi akwa etiti na paịlị na-ere ihe, na-esote akwa ọla edo imikpu n'elu nickel.ENIG na-enye uru dị ka ezigbo solderability, flatness, corrosion resistance, na mma soldering arụmọrụ.Njirimara ọla edo na-enyekwa aka n'igbochi oxidation, si otú a na-eme ka nkwụsi ike nke nchekwa ogologo oge.

2. Hot Air Solder Leveling (HASL): Nke a bụ usoro ọgwụgwọ elu ọzọ a na-ahụkarị.N'ime usoro HASL, a na-etinye paịlị na-ere ihe n'ime ihe mgbanaka a wụrụ awụ, a na-eji ikuku na-ekpo ọkụ na-afụpụ ya, na-ahapụkwa akwa akwa akwa akwa.Uru HASL gụnyere ọnụ ala dị ala, ịdị mfe nke nrụpụta na ịre ahịa, n'agbanyeghị na ihu ya na ịdị larịị nwere ike ịdị ala.

3. Electroplating Gold: Usoro a na-agụnye itinye akwa ọla edo n'ime pads na-ere ihe.Ọlaedo kacha mma n'omume eletriki na nguzogide corrosion, si otú a na-emeziwanye ogo ire ere.Agbanyeghị, ịgbanye ọla edo na-adịkarị ọnụ karịa ma e jiri ya tụnyere ụzọ ndị ọzọ.A na-etinye ya karịsịa na ngwa mkpịsị aka ọla edo.

4. Organic Solderability Preservatives (OSP): OSP gụnyere itinye ihe mkpuchi organic na paịlị na-ere ihe iji chebe ha pụọ ​​​​na ọxịdashọn.OSP na-enye ezigbo flatness, solderability, ma dabara maka ngwa ọrụ ọkụ.

5. Tin imikpu: Dị ka imikpu ọla edo, tin imikpu gụnyere ikpuchi ihe na-ere ihe na akwa tin.Tin imikpu na-enye ezigbo ọrụ ire ere yana ọ na-efu ọnụ ma e jiri ya tụnyere ụzọ ndị ọzọ.Agbanyeghị, ọ nwere ike ọ gaghị agafe ọla edo imikpu n'ihe gbasara nguzogide corrosion na nkwụsi ike ogologo oge.

6. Nickel/Gold Plating: Usoro a yiri ọla edo na-emikpu n'ime mmiri, ma mgbe ọ gbasasịrị nickel na-enweghị electroless, a na-ekpuchi akwa ọla kọpa na-esote ọgwụgwọ nchara.Usoro a na-enye ezigbo conductivity na nguzogide corrosion, dabara maka ngwa arụmọrụ dị elu.

7. Plating Silver: Ịtinye ọlaọcha na-agụnye ikpuchi ihe na-ere ihe na akwa ọlaọcha.Ọlaọcha dị mma n'ihe gbasara conductivity, mana ọ nwere ike oxidize mgbe ekpughere ya na ikuku, na-achọkarị oyi akwa nchekwa ọzọ.

8. Ike Gold Plating: A na-eji usoro a maka njikọ njikọ ma ọ bụ oghere kọntaktị nke chọrọ ntinye na mwepụ ugboro ugboro.A na-etinye akwa ọla edo ka ukwuu iji nye nguzogide iyi na arụmọrụ corrosion.
