Leli khono lisenza sibe nguzakwethu othembekile ezinkampanini ezithuthukisa izinhlelo zokuxhumana zesizukulwane esisha kanye nobuchwepheshe be-radar.

Yebo, sinikeza zombili izinsiza zokwenza amaphrothothiphu ngokushesha ngezikhathi ezijwayelekile ezifushane njengezinsuku ezi-3 kuya kwezi-5, kanye namandla okukhiqiza ngobuningi ngezikhathi zezinsuku ezi-15 kuya kwezi-20 kuye ngobunkimbinkimbi kanye nomthamo. Ingqalasizinda yethu ekhulayo isivumela ukuthi siguqule kalula kusukela kumaphrothothiphu siye ekukhiqizeni ngobuningi ngaphandle kokudinga ukuqinisekiswa kabusha noma izinguquko ezinkulu ekwakhiweni. Lokhu kuvumelana kusekela imijikelezo ejikelezayo yokuthuthukisa umkhiqizo, ivumela amakhasimende ethu ukuthi aqinisekise imiklamo yawo ngokushesha futhi afinyelele emakethe ngokushesha. Sisebenza eduze namakhasimende ukuhlela umthamo wokukhiqiza nokuqinisekisa ukuguquka okubushelelezi esigabeni ngasinye somjikelezo wokuphila womkhiqizo wawo.

Cabanga ngezinto ezifana nekhono lokukhiqiza (inani lezingqimba, usayizi webhodi, izinto ezitholakalayo), izitifiketi zekhwalithi (ISO 9001, ISO 14001), amakhono okuhlola (ukuhlola kwe-impedance, i-AOI), izikhathi zokulethwa, isakhiwo samanani, kanye nokujula kokusekelwa kwezobuchwepheshe. Bheka umlingani onjengo-Guangdong Inkue Technology onikeza ukubuyekezwa kwamahhala kwe-DFM, ukubonisana okukhethekile kwezobunjiniyela, kanye nensiza yokuthengisa ephendulayo ukuze usekele izidingo zakho. Hlola umlando womkhiqizi ngokusebenzisa izifundo zamacala kanye nezinkomba zamakhasimende embonini yakho ukuze uqinisekise ukuthi bayaziqonda izidingo zakho ezithile zokusebenzisa. Okubaluleke kakhulu, khetha umlingani obheka iphrojekthi yakho njengokubambisana kwesikhathi eside kunokuba kube ukuthengiselana okukodwa nje.

Sigcina isitifiketi se-ISO 9001 sezinhlelo zokuphatha ikhwalithi kanye nesitifiketi se-ISO 14001 sokuphatha imvelo, okubonisa ukuzibophezela kwethu kukho kokubili ukugqama kwekhwalithi kanye nezinqubo zokukhiqiza ezisimeme. Zonke izinqubo zethu zokukhiqiza zibhalwe phansi, zihlolwe njalo, futhi zithuthukiswa ukuze siqhubeke sithobela lawa mazinga omhlaba aqinile. Ithimba lethu lokuqinisekisa ikhwalithi lenza ukuhlolwa okuphelele kanye nokuhlolwa kukagesi kuwo wonke amabhodi akhiqizwayo, ngokulandeleka okuphelele kuyo yonke inqubo yokukhiqiza. Lezi zitifiketi kanye nezinqubo zinikeza amakhasimende ethu ukuzethemba kokuthi ama-high frequency PCB abo ahlangabezana namazinga aphezulu kakhulu ekhwalithi embonini.

Izikhathi ezijwayelekile zokulethwa yizinsuku ezi-3-5 kuma-oda wokuqala (prototype) nezinsuku ezi-15-20 zokukhiqiza ngobuningi, kuye ngobunkimbinkimbi bebhodi, inani lezingqimba, kanye nokutholakala kwezinto zokusebenza. Siphinde sinikeze izinsiza eziphuthumayo ngezidingo eziphuthumayo ngenani elengeziwe, sinikeze nezikhathi zokukhiqiza ezibekiwe kubathengi ababalulekile. Ithimba lethu linikeza izilinganiso ezinembile zokulethwa kusukela ekuqaleni futhi liyazibophezela ekuhlangabezaneni nalezi zinsuku, linikeze izibuyekezo eziqhubekayo phakathi nomjikelezo wokukhiqiza. Ukuze uxoxe ngezidingo zakho ezithile zesikhathi, siyakukhuthaza ukuthi uxhumane nethimba lethu lokuthengisa ukuze uthole uhlelo olukhethekile lwakho.
