Echiche Nnwale Na-efe efe, Uru na Ọdịmma nke PCB Flying Test

Nnwale iji efe efe bụ otu n’ime ụzọ iji lelee ọrụ eletrik nke PCB (ule sekit mepere emepe na nke dị mkpụmkpụ). Ihe nlele agịga na-efe efe bụ usoro maka ịnwale PCB na gburugburu nrụpụta. Ọ na-adịghị eji niile omenala bed nke online ule igwe-Ntu) interface, na-efe efe agịga ule na-eji anọ ruo asatọ onwe ha na-achịkwa nyocha ịkwaga n’ókè-na-atụ ule nke components n’okpuru ule. A na-ebufe UUT (otu n’okpuru ule) na ọdụ ule site na eriri ma ọ bụ usoro mgbasa ozi UUT ọzọ
N’ime igwe. Emezizie ya, nyocha nke igwe nnwale na-akpọtụrụ pad ule na site na iji nwalee otu ihe nke otu n’okpuru ule (UUT). A na-ejikọta nyocha ule na onye ọkwọ ụgbọ ala site na usoro multiplexing (signal generator, ike ọkọnọ, wdg) na sensọ (dijitalụ multimeter, ugboro counter, wdg) iji nwalee ihe ndị dị na UUT. Mgbe a na-anwale akụrụngwa, ihe ndị ọzọ dị na UUT na-echekwa ọkụ eletrik site na nyocha iji gbochie ịgụ nnyonye anya dijitalụ.

Ọdịiche dị n’etiti ule agịga na-efe efe na ule ngwa
◆ Igwe na-anwale agịga na-efe efe bụ ngwa a na-ahụkarị na-eji usoro capacitance. Nyocha ule na-aga ngwa ngwa site na isi ihe na bọọdụ sekit iji mechaa ule ahụ.
◆ Buru ụzọ mụta bọọdụ ọkọlọtọ wee gụọ uru ọkọlọtọ nke capacitance nke netwọkụ ọ bụla.
◆ buru ụzọ nwalee na usoro capacitance, wee kwenye nke ọma na usoro nguzogide mgbe ike a tụrụ atụ adịghị n’ime oke ruru eru.
◆ Enwere ike ịme nha ahịrị anọ.
◆ n’ihi na ngwa ngwa ule ọsọ, ọ bụ naanị adabara sample sample na obere ogbe.

Uru na ụkọ ihe ụfọdụ:
◆ agịga ule dị mfe imebi
◆ ngwa ngwa ule ọsọ
◆ Njupụta ule dị elu, na ọkwa kacha nta nwere ike iru 0.05mm ma ọ bụ obere
◆ enweghị ego nkwụnye ego, ịchekwa ego.
◆ enweghị ike ịnwale voltaji na-eguzogide, na ule ọkwa dị elu nwere nnukwu ihe ize ndụ.
