Usoro mmepụta PCB

Nzọụkwụ 1: Nyochaa data

Tupu mmepụta, onye na-emepụta PCB na-enyocha data nhazi osisi nke onye ahịa nyere, gụnyere nha osisi, usoro chọrọ, na ọnụ ọgụgụ ngwaahịa. Mmepụta na-enweta naanị mgbe ya na ndị ahịa nwetachara nkwekọrịta.

Nzọụkwụ 2:Ịcha ihe

Dị ka ozi ndị na-emepụta ihe na-eme ka ndị ahịa si dị, belata mbadamba mmepụta n'ime obere iberibe nke na-emezu ihe ndị a chọrọ. Ọrụ a kapịrị ọnụ: nnukwu efere efere → ịcha dị ka MI chọrọ → ịcha efere → ịkpụ nkuku / nkuku → mwepu efere.

Kwụpụ 3: Na-egwu mmiri

Gwuo dayameta oghere achọrọ n'ọnọdụ kwekọrọ na bọọdụ PCB. Ọrụ a kapịrị ọnụ: nnukwu efere efere → ịcha dị ka MI chọrọ → ọgwụgwọ → ịkpụ nkuku / ichikota ọnụ → mwepụ efere.

Nzọụkwụ 4: Imi ọla kọpa

A na-edobe akwa ọla kọpa dị mkpa n'ime oghere mkpuchi. Specific arụmọrụ: siri ike egweri → nghọta osisi → akpaka ọla kọpa sinking akara → eweda osisi → tetara na 1% itughari H2SO4 → ndim ọla kọpa.

Nzọụkwụ 5: Nyefee onyonyo

Nyefee ihe oyiyi site na ihe nkiri mmepụta na osisi. Ọrụ dị iche iche: osisi hemp → ịpị ihe nkiri → guzoro → nhazi → ikpughe → guzoro → mmepe → nyocha.

Nzọụkwụ 6:Ihe osise eserese

Electroplate oyi akwa ọla kọpa nke ọkpụrụkpụ achọrọ na oyi akwa nickel ọla edo ma ọ bụ tin na mpempe ọla kọpa ekpughere ma ọ bụ mgbidi oghere nke ụkpụrụ sekit. Ọrụ a kapịrị ọnụ: efere elu → degreasing → ịsacha mmiri nke abụọ → micro corrosion → ịsacha mmiri → ịsacha acid → plating ọla kọpa → ịsacha mmiri → ịsacha acid → tin plating → mmiri ịsacha → ala efere.

Nzọụkwụ 7: Mwepụ ihe nkiri

Wepu oyi akwa mkpuchi mgbochi electrolating na ngwọta NaOH iji kpughee oyi akwa ọla kọpa na-abụghị okirikiri.

Kwụpụ 8: Mwepu

Wepu akụkụ ndị na-abụghị okirikiri site na iji reagent kemịkal.

Kwụpụ 9: Mkpuchi solder

Nyefee onyonyo nke ihe nkiri akwụkwọ ndụ akwụkwọ ndụ na bọọdụ ahụ, ọkachasị iji chebe sekit ma gbochie ire nke akụkụ nwere tin na sekit.

Nzọụkwụ 10: Ihuenyo silk

Bipụta mkpụrụedemede enwere ike ịmata na bọọdụ PCB. Arụ ọrụ akọwapụtara: mgbe ọgwụgwọ ikpeazụ nke nkpuchi solder gasịrị, dị jụụ ma guzoro otu ebe, dozie ihuenyo ahụ, bipụta mkpụrụedemede, wee gwọọ ya n'ikpeazụ.

Kwụpụ 11: Mkpịsị aka ọla edo

Tinye akwa nickel/ọlaed nke ọkpụrụkpụ achọrọ na mkpịsị aka plọg iji kwalite ike ya na iyi ihe mgbochi.

Nzọụkwụ 12: Ịmepụta

Punch udi nke onye ahịa chọrọ site na iji igwe ebu ma ọ bụ CNC.

Nzọụkwụ 13: Nnwale

Nrụrụ arụrụ arụ nke sekit mepere emepe, obere sekit, wdg, siri ike ịchọpụta site na nlele anya na enwere ike ịnwale ya site na iji ihe nleba anya na-efe efe.
