BQC' kev taw qhia
BQC raws li koj qhov kev daws teeb meem ib leeg, peb saib xyuas txhua yam los ntawm kev yuav khoom (kev pabcuam puv ntoob), kev tsim khoom, kuaj thiab kev xa khoom, chaw nres nkoj lossis chaw nres nkoj rau kev lag luam uas pab peb cov neeg siv khoom los ntawm kev tsim khoom, tom qab ntawd lawv tuaj yeem tsom mus rau kev lag luam thiab kev muag khoom. Peb ua txhua qhov kev sim los pab cov neeg siv khoom kom txo nqi kom lawv cov kev sib tw ua lag luam tsis muaj kev cuam tshuam ntawm qhov zoo. Yog li, peb tau txais lub koob npe zoo thiab pom lub hauv paus ntawm peb txoj kev koom tes ntev nrog peb cov neeg siv khoom.

Dab tsi yog qhov impedance yam cuam tshuam rau PCB pov thawj?
Cov khoom siv hluav taws xob xa cov kab teeb liab, nws cov teeb liab ntau zaus lossis electromagnetic yoj propagation tsis kam ntsib thaum hu ua tus yam ntxwv impedance. Hauv kev ua pov thawj PCB, thaum muaj cov teeb liab ntau zaus kis tau los ntawm lub rooj tsavxwm, PCB tus yam ntxwv impedance tus nqi yuav tsum tau sib phim nrog cov hluav taws xob impedance ntawm lub taub hau thiab tus Tsov tus tw; ib zaug tsis sib xws, lub zog hluav taws xob xa hluav taws xob yuav cuam tshuam, tawg, tawg lossis ncua qhov tshwm sim, cuam tshuam rau lub teeb liab kev ncaj ncees. Nyob rau hauv cov ntaub ntawv no, impedance tswj yuav tsum tau nqa tawm kom lub PCB tus yam ntxwv impedance qhov tseem ceeb raws li cov khoom.
Los ntawm PCB pov thawj pom, qhov tseem ceeb cuam tshuam rau impedance yog
W----- kab dav/interline: kab dav tsub kom impedance ua me me, nrug nce impedance nce.
H---- rwb thaiv tsev thickness: nce thickness nce impedance.
T------ tooj liab thickness: nce tooj liab thickness txo impedance.
H1 - ntsuab roj thickness: nce thickness txo impedance.
Er----- dielectric tas li: DK tus nqi nce, impedance txo.
Undercut----undercut nce, impedance yuav loj dua.
Lus Cim: solder kuj tseem muaj kev cuam tshuam rau impedance, tsuas yog vim lub solder tiv thaiv txheej txuas nrog lub dielectric, ua rau muaj zog dielectric tas li, qhov no yuav raug ntaus nqi los ntawm kev cuam tshuam ntawm dielectric tas li, tus nqi impedance yuav raug txo los ntawm kwv yees li 4 feem pua. raws li.
Cov lus ceeb toom tshwj xeeb: Hauv kev pov thawj PCB, kev tswj hwm impedance yog txheej txheem tshwj xeeb, kev ua haujlwm nyuaj, ua rau qee lub tuam txhab PCB teeb meem ntau dhau, tsis xav ua lossis tsawg dua.
