The tensile simba uye elongation yefoil yemhangurazviratidzo zviviri zvakakosha zvezvinhu zvemuviri, uye kune humwe hukama pakati pavo, izvo zvinokanganisa zvakananga kunaka uye kuvimbika kwefoil yemhangura.
Kusimba kwesimba kunoreva kugona kwefoiri yemhangura kuramba kutsemuka kutyoka pasi pechiito chesimba, chinowanzo ratidzwa mu megapascals (MPa). Elongation inoreva kugona kwechinhu kuita deformation yepurasitiki panguva yekutambanudza, inoratidzwa sechikamu. The tensile simba uye elongation yefoil yemhanguravanobatwa panguva imwe chete nekukora uye saizi yezviyo, uye tsananguro yeiyi saizi mhedzisiro inofanirwa kuunza iyo dimensionless ukobvu-zviyo saizi reshiyo (T / D) seyekuenzanisa parameter. Iyo yekusiyanisa pateni yekusimba kwesimba yakasiyana muakasiyana makubvu-zviyo saizi reshiyo, nepo kureba kunodzikira nekudzikiswa kwekukora kana ukobvu-zviyo saizi reshiyo yakafanana.
Mumashandisirwo anoshanda, senge mukugadzirwa kwemapuranga edunhu akadhindwa(PCBs), zviyero zvinonzwisisika zvekusimba uye kurebesa zvinogona kuve nechokwadi chekuti chigadzirwa hachiwanzo kutsemuka kana deformation panguva yekushandiswa, nekudaro kuve nechokwadi chemhando uye kuvimbika kwechigadzirwa. Pakuyedzwa kwekusimba kwefoiri yemhangura, kune akasiyana mwero uye nzira dzekuona zvivakwa izvi, senge IPC-TM-650 2.4.18.1A chiyero, iyo yakanyatsogadzirirwa foil yemhangura yemabhodhi edunhu akadhindwa uye inopa yakadzama nzira dzekuyedza uye mapoinzi.
Paunenge uchiyedza kusimba kwekusimba uye kurebesa kwemhangura foil, zvinhu zvekufunga nezvazvo zvinosanganisira saizi yemuenzaniso, kukurumidza kuyedza, tembiricha mamiriro, nezvimwe. Semuenzaniso, iyo ASTM E345-16 chiyero inopa nzira dzekutemesa kuyedzwa kwesimbi foil, kusanganisira yakadzama paramita senge saizi yemuenzaniso, kukurumidza kuyedza, etc. Iyo GB/T 5230-1995 chiyero, kusanganisa saizi ye electrolytic, kune rumwe rutivi, inoteedzera saizi yecopper. gauge kureba, chinhambwe pakati pezvisungo, uye bvunzo muchina wekusimbisa kumhanya.
Muchidimbu, kusimba kwekusimba uye kurebesa kwemhangura foil zviratidzo zvakakosha zvekuyera zvimiro zvayo zvemuviri, uye hukama hwavo uye nzira dzekuyedza dzakakosha pakuona kunaka uye kuita kwekushandisa kwe.foil yemhangurazvinhu.
