5. Pin ọnwụ igwe maka components
Eji maka igbutu na nrụrụ pin components.
6. Efe ire ere
Igwe ịgbado ọkụ bụ ikwe ka elu ịgbado ọkụ nke nkwụnye ihe nkwụnye ahụ na kọntaktị mmiri mmiri dị elu ozugbo iji nweta ebumnuche ịgbado ọkụ, mmiri ọkụ ya dị elu iji nọgide na-enwe mmasị n'elu, yana site na ngwaọrụ pụrụ iche iji mee ka mmiri mmiri gbado agbado. yiri ife ofufe onu, nke a na-akpọ "ebili mmiri soldering", ya isi ihe bụ solder mmanya.
7. Tin oven
N'ozuzu, ọkụ tin na-ezo aka n'iji ọkụ eletrik eme ihe na ngwá ọrụ ịgbado ọkụ.N'ihi na discrete components sekit bọọdụ ịgbado ọkụ agbanwe agbanwe, mfe na-arụ ọrụ, ngwa ngwa, elu arụmọrụ, bụ gị ezi inyeaka na mmepụta na nhazi.
8. Igwe ịsa akwa

9. ICT ule nkwụnye
A na-ejikarị ule ICT iji nwalee sekit mepere emepe, obere sekit na ịgbado ọkụ nke akụkụ niile nke PCBA site na ịkpọtụrụ ebe nlele nke nhazi PCB.
10. FCT ule nyocha
FCT na-ezo aka na usoro nnwale nke na-enye gburugburu ebe ọrụ simulated (akpali akpali na ibu) maka UUT: Unit Under Test, na-enyere ya aka ịrụ ọrụ na steeti nhazi dị iche iche, iji nweta paramita nke steeti ọ bụla iji nyochaa ọrụ nke UUT.N'ikwu ya n'ụzọ dị mfe, ọ pụtara na UUT na-ebu ihe mkpali kwesịrị ekwesị ma tụọ ma nzaghachi mmepụta ahụ kwekọrọ n'ihe achọrọ.
11. Nnwale ịka nká
Ogbe ule ịka nká nwere ike ịnwale bọọdụ PCBA na batches.Enwere ike ịnwale bọọdụ PCBA nwere nsogbu site na ịmegharị ọrụ onye ọrụ ogologo oge.
