Surface Mount Technology (SMT): Cov thev naus laus zis ntawm kev ua cov khoom lag luam liab qab PCB thiab txuas cov khoom siv hluav taws xob ntawm PCB pawg thawj coj saib.Qhov no yog cov khoom siv hluav taws xob nrov tshaj plaws niaj hnub no nrog cov khoom siv hluav taws xob tau txais me me thiab ib qho kev hloov maj mam hloov DIP plug-in technology.Ob lub thev naus laus zis tuaj yeem siv rau ntawm tib lub rooj tsavxwm, nrog rau kev siv tshuab thru-qhov siv rau cov khoom siv tsis haum rau qhov chaw mounting xws li cov transformers loj thiab cov hluav taws xob hluav taws xob hluav taws xob semiconductors.
Ib qho khoom siv SMT feem ntau yog me dua nws qhov sib tw ntawm qhov sib tw vim tias nws muaj cov coj me me los yog tsis muaj txhuas txhuas.Tej zaum nws yuav muaj cov pins luv luv los yog coj ntawm ntau yam qauv, kev sib cuag tiaj tus, lub matrix ntawm solder balls (BGAs), los yog txiav tawm ntawm lub cev ntawm cov khoom.
Tshwj xeeb nta:
> Kev kub ceev tuaj tos & qhov chaw tshuab teeb tsa rau txhua qhov me me, nruab nrab mus rau loj khiav SMT sib dhos (SMTA).
> X-ray tshuaj xyuas rau qhov zoo SMT Assembly (SMTA)
> Cov kab sib dhos muab qhov tseeb +/- 0.03 hli
> tuav cov vaj huam sib luag loj txog li 774 (L) x 710 (W) mm loj
> Kov cov khoom loj rau 74 x 74, Qhov siab txog li 38.1 hli
> PQF tuaj tos & qhov chaw tshuab muab peb qhov yooj yim dua rau kev khiav me me thiab cov qauv qauv tsim.
> Tag nrho cov PCB sib dhos (PCBA) ua raws li IPC 610 chav kawm II tus qauv.
> Nto Mount Technology (SMT) tuaj tos thiab tso lub tshuab muab peb lub peev xwm ua haujlwm ntawm Surface Mount Technology (SMT) cov khoom ntim me dua 01 005 uas yog 1/4 qhov loj ntawm 0201 tivthaiv.
