2. Qhia cov ntaub ntawv
Uniwell circuits tau pom nyob rau hauv 2007, nrog 10+ xyoos txoj kev loj hlob, Peb teeb muaj pab pawg neeg haib R & D, yog li ntawd peb tuaj yeem tsim kho thiab tsim peb muaj peev xwm thiab tawm kev teeb tsa kom tau raws li txhua tus neeg yuav tsum tau ua, los ntawm kev tsim khoom ntawm ib yam khoom tshwj xeeb kom tiav qhov project management. Nrog nplua nuj kev nyob rau hauv pcb fabrication, Cheebtsam sourcing thiab pcb los ua ke kev pab. Raws li kev lag luam pcb & pcba kev, Kom ua tau zoo tshaj plaws thiab cov qauv qhia meej tshaj plaws yog peb lub hom phiaj.
Coj kom zoo dua peb lub dag zog thiab kev ua haujlwm thiab cia peb pab koj tuav koj cov kev sib tw. peb zoo positioned los txhawb peb cov neeg muas zaub los ntawm tag nrho cov khoom khoom lub neej, los ntawm lub tswv yim mus ntim ntau lawm. Peb tab tom yuav ua koj tus khub ntev nyob hauv Suav.

4. Feem ntau cov qauv thiab cov txiaj ntsig ntawm lub looj ntsej muag peelable yog:
● Sij hawm thiab nqi txuag nyiaj txuag piv rau cov kaspev
● Kev tiv thaiv ntawm cov txheej txheem thiab duab los ntawm kev ntsuam xyuas kev lag luam
● Kev tiv thaiv ntawm cov chaw xaiv ntawm PCB thaum muaj ntau txheej txheem los yog sib dhos
● Kev tiv thaiv (tenting) ntawm plated los ntawm qhov (PTH)
● Daws cov pa roj carbon ntau dua
● Ua haujlwm nyob hauv cov txheej txheem plating (eg electrolessess / electrolytic Copper or Tin plating)
● Kev tiv thaiv thaum Flex lossis Flex-Rigid process
● Ib qho yooj yim tshem tawm thiab nplooj tsis muaj qhov seem
● Cov khoom tsis muaj paug, cov uas tsis zawm, thiab tsis txhuam
● Ua raws li RoHS
● Siv cov hmoov txhuas tsis txhuas los sis hmoov txhuas xyaw lossis hmoov txhuas xyaw
● Ruaj rau 550 ° F (288 ° C)
