Ntak bọọdụ sekit e biri ebi chọrọ njikwa impedance?

N'ahịrị mgbama nnyefe nke ngwaọrụ eletrọnịkị, nguzogide na-ezute mgbe mgbama ugboro dị elu ma ọ bụ ebili mmiri electromagnetic na-agbasa ka a na-akpọ impedance.Gịnị mere mbadamba PCB ga-abụ impedance n'oge nrụpụta usoro nke ụlọ ọrụ sekit osisi?Ka anyị nyochaa site na ihe anọ ndị a:

1. Nke PCB sekit osisi nke ụlọ ọrụ sekit ụlọ ọrụ kwesịrị ịtụle nkwụnye na ịwụnye ngwa eletriki, na mgbe e mesịrị SMT patch njikọ kwesịkwara ịtụle okwu ndị dị ka conductivity na mgbaàmà nnyefe arụmọrụ, otú ahụ ala impedance, mma.

3. Ngwunye tin nke mbadamba pcb bụ ihe kachasị emetụta nsogbu na mmepụta nke ụlọ ọrụ sekit dum, ọ bụkwa isi njikọ nke na-emetụta impedance;ya nnukwu ntụpọ bụ mfe ọxịdashọn ma ọ bụ deliquescence, ogbenye solderability, na-eme ka sekit osisi siri ike solder na oke impedance.Elu, na-akpata adịghị mma conductivity ma ọ bụ akwusighị ike nke n'ozuzu osisi arụmọrụ.

4. Ndị na-eduzi na PCB sekit osisi nke ụlọ ọrụ sekit ga-ebunye akara dị iche iche.Sekit ahụ n'onwe ya ga-agbanwe uru nke impedance n'ihi etching, ikpo ọkụ, obosara waya na ihe ndị ọzọ, nke ga-eme ka mgbaàmà ahụ gbanwee ma na-eduga na bọọdụ sekit.Arụmọrụ dara, yabụ ịkwesịrị ijikwa uru impedance n'ime oke ụfọdụ
