Dab tsi yog kev sib txheeb ntawm tooj liab cov ntawv ci tensile lub zog thiab elongation?

Tooj liab ntawv nyiajYog ob qho khoom siv lub cev tseem ceeb ntawm lub cev, thiab muaj qee qhov kev sib raug zoo ntawm lawv, uas cuam tshuam ncaj qha cuam tshuam rau qhov zoo thiab kev ntseeg siab ntawm tus tooj liab ntawv ci.

Tensile lub zog yog hais txog kev muaj peev xwm ntawm tooj liab ntawv los tiv thaiv tensile bensure raws li kev ua ntawm lub zog, feem ntau qhia hauv MegapScals (MPA). Elongation refers to the ability of the material to undergo plastic deformation during the stretching process, expressed as a percentage. The tensile strength and elongation ofTooj liab ntawv nyiajyog ib txhij cuam tshuam los ntawm thickness thiab grain loj, thiab cov lus piav qhia ntawm cov nyhuv loj-lis loj piv (T / D) raws li kev sib piv parameter. Lub zog sib txawv ntawm lub zog tensile muaj qhov sib txawv ntawm cov tuab tuab-li kev txo qis ntawm cov tuab thaum lub thickness-grain loj me me yog tib yam.

(PCBs), tus qauv tsim nyog rau tensile lub zog thiab elongation tuaj yeem ua kom cov khoom tawg lossis deformation thaum siv, yog li ntseeg tau qhov zoo thiab kev ntseeg tau ntawm cov khoom. Rau kev sim cov khoom lag luam tooj liab, xws li IPC-TM-650 2.4.18.18.18.18.18.18.18.1 tus qauv uas luam tawm cov qauv luam tawm thiab muab cov ncauj lus kom ntxaws thiab cov ntsiab lus ntsuas kom ntxaws thiab cov ntsiab lus.

Thaum kuaj cov tensile lub zog thiab elongation ntawm tooj liab ntawv ci, cov qauv ntsuas, thiab lwm yam, ntawm qhov kev ntsuas kub, thiab lwm yam, ntawm qhov kev ntsuas kub, thiab lwm yam. electrolytic copper foil, including sample size, gauge length, distance between clamps, and test machine clamp speed.

Hauv cov ntsiab lus, lub zog tensile thiab elongation tooj ntawm tooj liab ntawv yog ntsuas nws txoj kev sib raug zoo thiab kev sim siab rau kom ua tau zoo thiab kev ua tiav ntawmTooj liab ntawv nyiajCov ntaub ntawv.
