Circuit Board nrog impedance

Rau PCB, lub rooj tsavxwm nrog cov kab impedance feem ntau hu ua impedance board.

Impedance board tseem hu ua impedance strip. Cov qauv laminated zoo tuaj yeem tswj cov yam ntxwv impedance ntawm PCB, thiab nws txoj kev tuaj yeem tsim cov kab sib txuas uas yooj yim los tswj thiab kwv yees. Nyob rau hauv ib lub voj voog nrog kev ua haujlwm, inductance thiab capacitance, qhov kev tiv thaiv rau qhov tam sim no hauv Circuit Court yog hu ua impedance. PCB board impedance yog hais txog qhov tsis kam thiab reactance tsis cuam tshuam AC tam sim no.

Feem ntau yam cuam tshuam rau impedance

1. Qhov nruab nrab thickness (lub phaj ob sab yog tsuas yog lub thickness ntawm FR4 integral substrate phaj, thiab ntau txheej board yog lub thickness ntawm PP ntawv thiab core phaj)

2. Kab dav thiab kab sib nrug (ob qho tib si kab dav thiab qhov kev ncua deb ntawm kab yuav cuam tshuam rau tus nqi impedance)

3. Copper thickness (qhov tiav tooj liab thickness feem ntau yog 1OZ, thiab tus nqi impedance kuj yuav cuam tshuam yog tias lub ntsej muag tooj liab tsis txaus)

4. Dielectric tas li (ntawm no yog hais txog qhov dielectric tas li ntawm tus number case thiab dielectric thickness)
