Ingaba iimoto zamandla amatsha zifikelela njani kwi-vacuum assisted braking? | Amandla e-VET
ngu admin on 24-12-18
Iimoto zamandla amatsha azixhotyiswanga ziinjini zamafutha, ke zifikelela njani kwi-vacuum-assisted braking ngexesha lokuqhobosha? Izithuthi zamandla amatsha ubukhulu becala zifumana uncedo lwebrake ngokusebenzisa iindlela ezimbini: Indlela yokuqala kukusebenzisa inkqubo yokuqhotsa i-vacuum booster yombane. Le nkqubo isebenzisa ivac yombane...

Wafer warpage, ukwenza ntoni?
ngu admin on 24-12-16
Kwinkqubo ethile yokupakisha, izinto zokupakisha ezinee-coefficients ezahlukeneyo zokwandiswa kwe-thermal zisetyenziswa. Ngethuba lenkqubo yokupakisha, i-wafer ifakwe kwi-substrate yokupakisha, kwaye emva koko amanyathelo okufudumeza kunye nokupholisa ayenziwa ukugqiba ukupakisha. Nangona kunjalo, ngenxa yokungahambelani phakathi ...
