Dhawunirodha uye Gadzirisa
Rondedzero iyi inopa pokutangira pakazara. Gadzirisa zvinhu zvichienderana nezvaunoda, kuoma kwekugadzira, uye kugona kwemubatsiri wekugadzira.
Kuti muwane ongororo yeDFM yemahara muchishandisa runyorwa urwu, tumirai mafaira enyu ekugadzira kuHighleap Electronics. Chikwata chedu chemainjiniya chichapa mushumo wakadzama weDFM unoratidza chero matambudziko anopesana nezvinodiwa izvi.
Charles ane ruzivo rwemakore anopfuura gumi mukugadzira mainjiniya ePCB CAM nemagetsi, achinyanya kuongorora mafaira ePCB, kuongorora DFM, uye kugadzirira kugadzirwa kwemabhodhi e multilayer, HDI, RF, uye high-speed. Ane hunyanzvi muGenesis, InCAM, uye CAM350, anovimbisa data rakarurama, maitiro akagadzikana, uye goho guru rekugadzira.
KuHighleap Electronics, anonyanya kutarisa pakugadzirisa mashandiro uye kuongorora kugona kwekugadzira kuti abatsire vatengi kuderedza njodzi, kupfupisa nguva yekutungamira, uye kuwana mhedzisiro yezvigadzirwa yakavimbika.
