N'ime usoro mmepụta PCB, usoro ọgwụgwọ elu bụ nzọụkwụ dị oke mkpa. Ọ bụghị naanị na ọ na-emetụta ọdịdị PCB, kamakwa ọ na-emetụtakwa ọrụ, ntụkwasị obi na ịdịte aka nke PCB. Usoro ọgwụgwọ n'elu nwere ike inye mkpuchi nchebe iji gbochie mmebi ọla kọpa, kwalite ịrụ ọrụ ire ere, ma nye ezigbo mkpuchi ọkụ eletrik. Ihe na-esonụ bụ nyocha nke ọtụtụ usoro ọgwụgwọ elu na-emekarị na mmepụta PCB.
一.HASL (Na-ekpo ọkụ Ikuku Smoothing)
Planarization ikuku na-ekpo ọkụ (HASL) bụ teknụzụ ọgwụgwọ elu PCB ọdịnala nke na-arụ ọrụ site na itinye PCB n'ime mgbanaka / ndu a wụrụ awụ wee jiri ikuku na-ekpo ọkụ mee “planarize” elu iji mepụta mkpuchi ọla edo edo. Usoro HASL dị ọnụ ala ma dabara adaba maka nrụpụta PCB dị iche iche, mana enwere ike ịnwe nsogbu na paịlị na-enweghị isi na mkpuchi mkpuchi igwe na-ekwekọghị ekwekọ.
ENIG (chemical nickel gold)
Electroless nickel gold (ENIG) bụ usoro na-etinye akwa nickel na ọla edo n'elu PCB. Nke mbụ, a na-ehichapụ elu ọla kọpa ma na-arụ ọrụ, mgbe ahụ, a na-edobe oyi akwa nke nickel site na mmeghachi omume ngbanwe nke kemịkalụ, n'ikpeazụkwa, a na-etinye akwa ọla edo n'elu oyi akwa nickel. Usoro ENIG na-enye ezigbo nguzogide kọntaktị ma na-eyi nkwụsi ike ma dị mma maka ngwa nwere ihe a pụrụ ịdabere na ya dị elu, mana ọnụ ahịa ya dị elu.
三, ọla edo kemịkalụ
Ọlaedo kemịkalụ na-edobe obere oyi akwa ọla edo ozugbo n'elu PCB. A na-ejikarị usoro a eme ihe na ngwa ndị na-achọghị ịgbazinye, dị ka ugboro redio (RF) na sekit microwave, n'ihi na ọla edo na-enye ezigbo conductivity na nguzogide corrosion. Ọlaedo kemịkalụ na-erughị ENIG, mana ọ naghị ewu ewu ka ENIG.
四, OSP (ihe nkiri nchebe organic)
Ihe nkiri nchebe Organic (OSP) bụ usoro na-emepụta ihe nkiri organic dị mkpa n'elu ọla kọpa iji gbochie ọla kọpa site na oxidizing. OSP nwere usoro dị mfe yana ọnụ ala dị ala, mana nchebe ọ na-enye adịghị ike ma dabara adaba maka nchekwa na iji PCB dị mkpirikpi.
五, ọla edo siri ike
Hard Gold bụ usoro na-etinye akwa ọla edo kariri n'elu PCB site na iji ọkụ eletrik. Ọlaedo siri ike na-eguzogide iyi karịa ọla edo kemịkalụ ma dabara adaba maka njikọ ndị na-achọ nkwụnye na nkwụnye ma ọ bụ PCB ndị a na-eji na gburugburu ebe ọjọọ. Ọlaedo siri ike na-efu karịa ọla edo kemịkal mana ọ na-enye nchebe ogologo oge ka mma.
Ọlaọcha imikpu
Silver imikpu bụ usoro maka itinye akwa ọla ọcha n'elu PCB. Silver nwere ezigbo conductivity na reflectivity, na-eme ka ọ dabara maka ngwa anya na infrared. Ọnụ ego nke usoro ọlaọcha nke imikpu ahụ dị oke oke, mana oyi akwa ọlaọcha na-adị mfe vulcanized ma chọọ ihe nchebe ọzọ.
七, Immersion Tin
Tin imikpu bụ usoro maka idobe oyi akwa n'elu PCB. Tin oyi akwa na-enye ezigbo soldering Njirimara na ụfọdụ corrosion iguzogide. Usoro tin imikpu dị ọnụ ala, mana oyi akwa na-adị mfe oxidized ma na-achọkarị mkpuchi nchebe ọzọ.
八, HASL na-enweghị ndu
HASL na-enweghị Lead bụ usoro HASL kwekọrọ na RoHS nke na-eji tin/ọlaọcha/ọla kọpa na-enweghị ndu dochie tin/lead alloy ọdịnala. Usoro HASL na-enweghị isi na-enye arụmọrụ yiri nke HASL ọdịnala mana ọ na-emezu ihe achọrọ gburugburu ebe obibi.
Enwere usoro ọgwụgwọ elu dị iche iche na mmepụta PCB, na usoro ọ bụla nwere uru pụrụ iche na ọnọdụ ngwa. Ịhọrọ usoro ọgwụgwọ elu kwesịrị ekwesị chọrọ ịtụle gburugburu ngwa ngwa, ihe ndị chọrọ ịrụ ọrụ, mmefu ego ọnụ na ụkpụrụ nchebe gburugburu ebe obibi nke PCB. Site na mmepe nke teknụzụ eletrọnịkị, usoro ọgwụgwọ elu ọhụrụ na-aga n'ihu na-apụta, na-enye ndị na-emepụta PCB ọtụtụ nhọrọ iji gboo mkpa ahịa na-agbanwe agbanwe.
