PCBs yog ib qho tseem ceeb heev rau kev lag luam sib txuas lus. Ib qho siv nrov ntawm PCCs yog rau kev sib txuas lus ua haujlwm. Koj yuav pom PCBs hauv xov tooj switching systems, yees duab kev sib tham, PBX systems thiab Voice Vev Xaib Hauv Kev Sib Cai, lossis VoIP. Kev sib txuas lus PCBs kuj raug siv rau hauv kev sib txuas lus sib xws xws li xovtooj ntawm tes, cov phom sij, cov kev khiav tsheb ceev thiab cov neeg siv khoom thiab kev siv xov tooj. Kev sib txuas lus PCBs kuj tseem siv los tswj cov kev ntsuas LED thiab cov yeeb yam. Uniwell Circuits Co., Ltd, tau tsim hauv Shenzhen, Tuam Tshoj hauv 2007. Uniwell Circuits yog lub tuam txhab muaj kev lag luam uas tau txais kev tso cai rau ISO9001, ISO14001, TS16949, UL. Peb xav kom koj ua tus khub rau hauv Suav.
2. Qhia cov ntaub ntawv
Uniwell Circuits Co., Ltd, tau tsim tsa hauv Shenzhen, Tuam Tshoj hauv lub Plaub Hlis, 2007. Uniwell Circuits yog ib lub tuam txhab muaj kev lag luam tshwj xeeb hauv kev tsim, kev tsim kho, kev tsim thiab muag khoom ntawm cov neeg muaj kev sib txuam nrog ntau tshaj ob sab sib tw thiab Multilayer PCBs (Printed Circuit Board) ntawm ceev tig, prototype, nruab nrab thiab loj tagnrho.Peb muaj 2 cov nroj tsuag ntau lawm, uas tuaj yeem ntsib koj tag nrho cov lus txib.
Muaj kev paub zoo txog kev lag luam, cov khoom zoo, kev tsim cov khoom tsim tawm thiab cov kev pabcuam, Uniwell Circuits tau txais txiaj ntsim siab ntawm cov neeg tuaj thoob lub ntiaj teb, xws li Mainland China, Taiwan, USA, Nyiv, Russia, Lub teb chaws Yelemees, UK, Finland, Fabkis, Holland, Ltalis, Poland, Denmark, Australia, Brazil, Singapore, Thaib, thiab Malaysia.

Peb muab tag nrho cov kev pab cuam soj ntsuam: AOI, Kev Kuaj Ua Haujlwm, Hauv Kev Tshaj Xo Kev Ntsuas, X-Dais rau BGA
2) Shipping
Yog tias lub rooj tsav xwm ceev, Peb pheej xa cov qauv ntawm DHL, FedEx lossis UPS lwm yam. Yog tias nws tsis yog li ntawd, peb tuaj yeem xa los ntawm kev xa khoom xa khoom xa tuaj, nws yuav siv sij hawm ntau dua ua ntej koj txais cov khoom, tab sis tuaj yeem txuag koj qee cov nyiaj.
5.Koj paub koj tus thawj coj yog dab tsi
Q: Nws yog dab tsi?
Leaded Solder yog hom kev ua tiav tshaj plaws. Nws yog ib qho sib xyaw ntawm tin thiab cov hlau lead uas siv rau lub rooj tsavxwm. Cov khoom sib tov yog kwv yees li 63/37 mix ntawm tin / lead. Qee lub sij hawm hu ua 60/40 cais. Yuav raug xa mus rau SN67 lossis SN66
Lub caij nyoog uas nws ntws (yog kua) yog 485 degrees.
Nws yog ci iab nyiaj dawb tas.
Q: Vim li cas nws thiaj siv?
Nws yog siv ua qhov txheej txheem vim. Nws yog qhov zoo tshaj plaws rau cov laug cam nrog thru-hole technology. Qhov seem finish tsis yog heev rau SMDs los yog BGAs.
Q: Tus txheej txheem los ua kom tiav qhov tiav?
Cov txheej txheem raug yog HAL (Kub Cua Kub). Cov laug cam dipped mus rau hauv lub tank ntawm lub raj mis thiab tom qab cua tshuab riam tawm ntawm cov khib nyiab tshaj. Nws yog siv tom qab muag khoom muag tau ua lawm.
Q: Cov kev ntsuas tseem ceeb yog dab tsi?
Feem ntau yog qhov ntsuas ntawm cov Leaded Solder yog ntsuas tau, txawm hais tias lo lus nug no tuaj txog ntawm lub caij nyoog. IPC tus qauv yog qhov muag pom kev ntawm lub tooj.
Tus nqi kuj tseem tsawg heev rau lwm hom kev xeem.
