2. Qhia cov ntaub ntawv
1) Nthuav qhia txog Uniwell
Uniwell circuits tau tsim nyob rau hauv 2007, raws li nyob rau hauv Shenzhen, Tuam Tshoj, tshwj xeeb nyob rau hauv lub ntawm luam tawm Circuit Court boards. Raws li keeb kwm Tuam Tshoj raws li PCB chaw tsim hluav taws xob, Uniwell circuits manufactures ntau hom PCB, xws li ib sab PCB, ob chav PCB thiab ntau txheej PCB, mus txog 32 txheej. Peb cov khoom siv sib txawv yog siv rau cov teeb pom kev zoo xws li LED teeb, lub hwj chim, kev ntsuas, kev sib txuas lus, kev siv tshuab hluav taws xob, tsheb electronics thiab lwm yam lag luam. Peb muaj kev kub ntxhov ntawm cov kev pab cuam los ntawm PCB prototypes ceev kom ntim loj PCB.
2) Peb cov kab ntau lawm
Peb ua raws tus txheej txheem thoob ntiaj teb kev lag luam.
3) Ntawv pov thawj
3.Cov khoom siv ntiag tug
Uniwell ntsuam xyuas cov nyiaj hauv cov khoom siv hluav taws xob hauv kev lag luam thiab koom tes nrog cov khoom lag luam sab saum toj.
