1. Imikpu ọla edo usoro: Ebumnuche nke imikpu gold usoro bụ itinye a nickel-gold mkpuchi na ike agba, ezi nchapụta, ezigbo mkpuchi na ezi solderability n'elu PCB, nke nwere ike ihu ọma kewara anọ nkebi: pretreatment. (Degreeasing, micro-etching, activation, post-dipping), nickel immersion, immersion gold, post-treatment, (ịsacha ọla edo n'efu, ịsa DI, ihicha).

2. Tin na-efesa lead: Okpomọkụ eutectic nwere ndu dị ala karịa nke alloy enweghị ndu.Ọnụ ego a kapịrị ọnụ na-adabere na nhazi nke alloy na-enweghị ndu.Dịka ọmụmaatụ, eutectic nke SNAGCU bụ ogo 217.The soldering okpomọkụ bụ eutectic okpomọkụ gbakwunyere 30-50 degrees, dabere na mejupụtara.Ndozi n'ezie, eutectic na-eduga bụ ogo 183.Ike igwe, nchapụta, wdg ndu dị mma karịa enweghị ndu.
