Nke mbụ, a na-akụnye ihe mkpuchi ahụ nke ọma n'ime ebe a na-edobe ụlọ ahụ, na-enwe oke okpomọkụ nke ±1 ogo mgbe ejiri nrapado ọkụ kpuchie{4}}. Onye na-eduzi etiti ahụ na-akwado nkwado mkpuchi site na iji kọntaktị mmiri, a na-ejikwa ihe nlele laser iji chọpụta njehie coaxial (ihe na-erughị ma ọ bụ hà 0.01mm). A na-etinye obere griiz silicone na njikọ eriri iji belata ike ntinye. N'ikpeazụ, a na-emechi ụlọ ahụ site na iji igwe eji eme ihe raara onwe ya nye, na-achịkwa ike nke na-achịkwa n'ime oke 50-80N.
5. Nnwale arụmọrụ na njikwa ogo
Ngwaahịa emechara na-enweta usoro nyocha zuru oke: A na-anwale VSWR (voltage standing wave ratio) site na iji ihe nyocha netwọkụ, yana ihe achọrọ ihe na-erughị ma ọ bụ nhata 1.15 n'ime bandwit ugboro 20GHz. A na-atụ nguzogide kọntaktị site na iji ụzọ waya anọ{3}, nwere uru ọkọlọtọ nke<5mΩ. Durability testing includes checking contact wear after 500 plug-in and unplug cycles, and a 96-hour salt spray test to assess corrosion resistance. All data is recorded in real time through the MES system, keeping the defective rate below 0.3%.
