PCBs yog cov yoog raws thiab hloov tau yooj yim rau ntau cov kev siv thoob plaws kev lag luam. Tus neeg tsim nyog thiab cov chaw tsim hluav taws xob muaj peev xwm tsim tau ib qho txiaj ntsig zoo thiab tsim tau yooj yim PCB tov rau txhua daim ntawv thov. Yog tias koj tab tom nrhiav ib qhov chaw kho mob PCB zoo, Uniwell pab tau. Peb cov khoom siv dav dav hauv ntau qhov chaw, xws li MP3 / 4/5, neeg uas ua ntawv, hais lus, lub tsheb, lub computer thiab lwm yam.
2.Company profile
Uniwell circuits tau tsim xyoo 2007, nrog rau 100 tus neeg ua haujlwm thiab R & D cov neeg ua haujlwm, nrog rau 10+ xyoos ntawm kev txhim kho, peb ua qhov sib tw PCB thiab PCBA hauv Suav teb, nrog rau kev sib tw kuaj xyuas thiab ntsuas cov cuab yeej, tus nqi tsawg dua 0.1%. peb cov ntaub ntawv pov thawj los ntawm ntau tshaj li kev ruaj ntseg thoob ntiaj teb tus qauv thiab kev tiv thaiv ib puag ncig ntawm kev tiv thaiv, tsis tau peb tau raug pom zoo los ua ISO, UL, RoHs thiab lwm tus qauv, thiab peb cov neeg muas zaub los ntawm thoob plaws lub ntiaj teb, feem ntau ntawm Tebchaws Europe, Tebchaws Asmeskas, thiab Australia.
Cov kws tsav tsheb, cov neeg ua hauj lwm ua hauj lwm thiab cov khoom lag luam hauv siab tshaj plaws thiab cov cheeb tsam ntawm OEM, muab ntau yam kho PCB / PCBA sai thiab reliably, Uniwell tos ntsoov kom txaus siab rau koj los ntawm kev muab cov khoom zoo tshaj thiab zoo heev.
3.Application
Thaum koj xaiv los ua haujlwm nrog Uniwell, koj ua haujlwm nrog ib tus kws kho mob uas yog siab rau koj kev txaus siab thiab cov qauv zoo tshaj plaws. Tsis muaj teeb meem dab tsi ntawm PCB koj lub tuam txhab xav tau, peb tuaj yeem kho nws. Ob leeg - lossis ib leeg-ib tog, SMT, los ntawm qhov los yog sib xyaw ua ke, peb tuaj yeem ua rau tshwm sim hauv txoj kev siv nyiaj tsawg tshaj plaws. Tuaj saib xyuas peb qhov blog los yog hu rau peb kom paub ntxiv txog PCB designs thiab applications, los yog txhaj cov nyees khawm cov lus nram qab no rau kev ceev lus!
4. Dab tsi yog tooj qhwv?
Copper qhwv yog ib qho kev tso tawm ntawm daim npog uas tau tso rau hauv lub qhov ntawm lub qhov thiab nws txuas mus rau ntawm lub PCB (los yog ntawm cov tub ntxhais sab hauv lub hauv plab yog ib feem ntawm cov qauv HDI) yam tsawg kawg 25 um.
Rau cov chav kawm 2 xav tau qhov tuab ntawm qhov nyiaj tso ntawm qhov npog npuaj yog qhov tsawg kawg nkaus 5um, tab sis rau chav kawm 3 qhov no yuav txawv raws li qhov chaw ntawm no feature nyob rau hauv qhov tsim. Thov sab laj peb cov kws kho mob kom paub ntxiv txog chav kawm 3 xav tau.
5. Dab tsi yog capped ntawm qhov?
Ib qho capped ntawm yog thaum plating yog ntxiv tshaj ntawm ntawm qhov kom lub qhov kub yog hlau nrog qhov tsawg kawg yog tooj / hau plating tuab ntawm 5um rau chav kawm 2 xav tau, los yog 12um rau chav kawm 3 xav tau.
Qhov no yog vam khom rau ntawm kev sau cov ntaub ntawv uas yog epoxy resin as opposed to soldermask, raws li cov epoxy yuav txo cov kev pheej hmoo ntawm cov npuas cua los yog kev nthuav dav ntawm cov kev ua haujlwm nyob rau hauv kev ua haujlwm. Qhov no tuaj yeem categorized hauv IPC-4761 raws li hom VII - ntim thiab capped ntawm qhov. Nws yog feem ntau yog siv rau cov qauv siv nrog rau hauv ncoo los yog hauv BGA daim ntawv sau npe uas muaj cov ntom ntom siab uas yuav tsum muaj.
