Koporo ke lera le tloaelehileng la tšepe la conductive holim'a boto ea potoloho (PCB).Pele u hakanya khanyetso ea koporo ho PCB, ka kopo hlokomela hore ho hanyetsa ha koporo ho fapana le mocheso.Ho hakanya khanyetso ea koporo holim'a PCB, ho ka sebelisoa mokhoa o latelang.
Ha ho baloa boleng ba kakaretso ba khanyetso ea conductor R, ho ka sebelisoa foromo e latelang.
ʅ : bolelele ba mokhanni [mm]
W: bophara ba conductor [mm]
t: botenya ba conductor [μm]
ρ : conductivity ea conductor [μ ω cm]
Ho hanyetsa ha koporo ho 25°C, ρ (@ 25°C) = ~ ~1.72μ ω cm
Ho phaella moo, haeba u tseba ho hanyetsa koporo sebakeng sa yuniti, Rp, ka mocheso o fapaneng (joalokaha ho bontšitsoe setšoantšong se ka tlase), u ka sebelisa mokhoa o latelang ho hakanya ho hanyetsa ha koporo eohle, R. Hlokomela hore litekanyo tsa litekanyo koporo e bontšitsoeng ka tlase ke botenya (t) 35μm, bophara (w) 1mm, bolelele (ʅ) 1mm.
Rp: khanyetso sebakeng sa yuniti
ʅ: bolelele ba koporo [mm]
W: bophara ba koporo [mm]
t: botenya ba koporo [μm]
Haeba litekanyo tsa koporo li le 3mm ka bophara, 35μm ka bophara le 50mm ka bolelele, boleng ba ho hanyetsa R ba koporo ho 25 ° C ke
Kahoo, ha 3A hona joale e phalla koporo holim'a PCB holim'a 25 ° C, motlakase o theoha hoo e ka bang 24.5mV.Leha ho le joalo, ha mocheso o nyolohela ho 100 ℃, boleng ba ho hanyetsa bo eketseha ka 29% 'me ho theoha ha motlakase ho fetoha 31.6mV.
