Cov khoom siv hluav taws xob uas yooj yim npaj muaj ntau yam ntawm lub cev thiab hluav taws xob interconnect cov kev daws uas tsis tuaj yeem ua tiav nrog cov qauv kev sib tham ntawm lub rooj sib tham. Nrog 10 xyoo ntawm kev tsim ntau yam, Uniwell yog ib tus thawj coj hauv cov khoom hloov khoom, tsim tawm, thiab kev sib txoos ua ke kom muaj kev sib tw tau yooj yim.
2. Peb cov neeg muag khoom
Peb muaj kev sib koom tes ua ke nrog neeg ntiaj teb sab saum toj kawg nkaus.
Ua kom muaj kev sib raug zoo ntawm kev lag luam los ntawm kev sib txuas lus peb cov kev xav tau thiab kev xav tau. Cia tus neeg muag khoom rau hauv peb lub tswv yim zoo thiab koom nrog kev soj ntsuam cov khoom tshiab thiab cov txheej txheem.
3. Daim Ntawv Thov
Feem ntau cov khoom siv hluav taws xob tsis zoo yog siv cov khoom siv hluav taws xob sib txuas uas siv los txuas rau cov khoom siv hluav taws xob xws li cov resistor, capacitors, integrated circuits, thiab cov zoo li, tab sis qee qhov siv los ua kev sib txuas ntawm lwm cov koom sib txuas sib txuas lus ncaj qha los yog nrog cov neeg sib txuas. Nyob rau hauv lub tsheb, cov dav hlau ywj pheej yog siv hauv cov khoom siv hluav taws xob, hauv hood tswj, qhov kev sib tshuam kom muaj nyob rau hauv lub headliner ntawm lub tsev txias, thiab hauv cov tshuab ABS.
4.Luag tshaj paub --- Cov khoom siv hluav taws xob yooj yim
Muaj ob peb qhov tseem ceeb ntawm cov txee uas muaj ywj pheej, tab sis nws muaj qhov txawv ntawm qhov sib txawv ntawm cov neeg mob hauv lawv cov khoom. Nram qab no yog ib qho kev luj xyuas ntawm feem ntau hom kev kho vaj tse hauv koog tsev.
Single-sided saj zawg circuits
Ib kauj zuam hauv ib lub voj voog muaj ib tus neeg ua tus txheej txheem ntawm ib tus qauv hlau los yog cov khoom siv hluav taws xob (hlau ntim) ntawm lub tshuab xaim hluav taws xob. Kev tua cov nta ua haujlwm muaj nyob ntawm ib sab xwb. Taws yuav tsim (drilled los yog laser) nyob rau hauv zaj duab xis los luj kom cia tivthaiv ua kom dhau lub sijhawm rau kev sib tshuam, feem ntau yog los ntawm kab ntsig. Pheej ib sab ntawm ib sab tsuas muaj peev xwm muab xa los yog tsis muaj cov txheej txheem pov npav xws li cov khaubncaws sab nraud povtseg lossis lub tsho tiv no, txawm li cas los xij siv cov txheej txheem tiv thaiv kab tshooj saum toj no yog kev xyaum ua ntau tshaj.
Kev siv ntu mounted li ntawm cov yeeb yaj kiab ua yeeb yam tau ua qhov tsim tau ntawm qhov muag pom ntawm cov yeeb yam Films, uas yog siv hauv iav LED, tiamsis ntxiv rau hauv cov twj ywm tsheb yooj yim.
Ob tog sib nyhav sib luag
Ob lub voj voog thaiv ob sab phaj nyaj yog ib lub zaw hlau muaj ob lub rooj sib tshuam ntawm cov neeg. Thesis flex circuits tuaj yeem tsim tau los yog tsis tau plated los ntawm qhov, tab sis yog plated los ntawm qhov variation yog ntau ntau. Thaum tsim tsis muaj plated los ntawm lub qhov thiab cov koom txoos nta yog nkag tau los ntawm ib sab tsuas, qhov Circuit Court yog txhais tias yog "Hom 5" raws li cov tub rog.
Nws tsis yog ib qho kev xyaum, tab sis nws yog ib qho kev xaiv, lub sij hawm tso tawm rau hluav taws xob apparatus yog muab rau ob tog ntawm Circuit Court, yog li cia cov cuab yeej muab tso rau txhua sab. Raws li tsim cov khoom tsim, ob tog sib txuas hauv cov hluav taws xob yuav tsum tau muab pov thaiv nrog kev tiv thaiv npog cov khaubncaws sab nraud povtseg hauv ib, ob lossis ob sab ntawm Circuit Court tag, tiam sis feem ntau yog tsim los ntawm kev tiv thaiv txheej txheem ntawm ob sab. Ib qho txiaj ntsim ntawm hom qoob no yog qhov uas nws tso cai rau kev sib raug zoo kom npaj tau yooj yim heev. Ntau yam kev sib tw ua ke tau ua rau ntawm ob sab sib npaug tam sim ntawd txij li thaum lawv muaj ib feem ntawm ob txoj kev sib tshuam.
Sculptured saj zawg zog circuits
Sculptured flex circuits yog qhov tshiab sib cais ntawm cov qauv kho vaj tse yooj yim. Cov txheej txheem tsim muaj feem xyuam nrog ib qho kev sib tw ua ke nrog ntau txoj hauv kev uas ua rau cov khoom siv tau yooj yim uas tau ua tiav tau cov tooj liab uas tau ua rau cov neeg ua haujlwm sib txawv nyob hauv ob peb qhov chaw raws lawv qhov ntev. (xws li cov neeg sib tw ua nyias hauv thaj chaw yooj yim thiab tuab ntawm cov ntsiab lus sib txuas).
Multilayer saj zawg hluav taws xob
Flex circuits muaj peb los yog ntxiv cov txheej ntawm cov neeg sib tw uas raug hu ua cov kab hluav taws xob sib ntau. Feem ntau cov khaubncaws sab nraud povtseg yog txuas los ntawm txoj kev plated los ntawm qhov, tab sis qhov no tsis yog qhov kev txhais ntawm qhov txhais tau tias nws yog qhov muaj tseeb rau cov kev qhib rau kev nkag mus hauv qib qis. Cov khaubncaws sab nraud povtseg ntawm cov txawb tau ntau lub vev xaib los yog yuav tsis tau latelyated laminated ua ke thoob plaws hauv lub tsev nrog cov kev zam uas muaj kev ceeb toom ntawm cov cheeb tsam nrog plating hauv-qhov. Kev xyaum ntawm lam txwm lam yog paub nrog cov neeg mob uas tsis yooj yim. Qhov no yog ua tiav los ntawm kev tsis tshuav qhov chaw tsis hais qhov twg los yog khoov dabtsi.
Txaus-flex circuits
Rigid-flex circuits yog ib lub voj voog ua flex flex uas muaj cov yoojyim thiab yooj yim substrates uas yog laminated ua ke rau hauv ib tus qauv. Rigid flex flex circuits yuav tsum tsis txhob muaj kev ntxhov siab nrog cov rigidized flex constructions yog ib qho yooj yim flex circuits uas tus stiffener txuas nrog kom muaj qhov ceeb thawj ntawm cov khoom siv hluav taws xob hauv zos. Ib txoj hlua ruaj ruaj lossis nyhav nyhav nyhav nyhav nyhav yuav muaj ib los yog cov txheej txheem hluav taws xob. Yog li, thaum lub sij hawm ob qho lus yuav zoo tib yam, lawv qhia cov khoom uas muaj kev cuam tshuam. Cov khaubncaws sab nraud povtseg es feem ntau yog sib txuas los ntawm txoj kev plated ntawm qhov. Xyoo dhau, cov kev sib tw tsis yeem muaj xws li qhov zoo ntawm cov tub rog cov khoom tsim qauv; txawm tias cov cuab yeej tau pom muaj kev siv zoo hauv cov khoom lag luam.
Thaum uas nquag saib xyuas cov khoom tshwj xeeb rau cov ntawv tsis txaus siv raws li ntawm kev cov nyom, ib qho tshwj xeeb siv los siv technology yog npaj los ntawm Compaq computer hauv kev tsim ntawm cov laug cam rau lub computer laptop hauv lub xyoo 1990.Thaum lub computer kev ua haujlwm loj PCBA tsis siv los ntawm kev siv, ua tau zoo tsim los ntawm Compaq cov yeeb yaj kiab uas yooj yim rau cov hinged cov khoom pov thawj cable, dhau 10s ntawm 1000 tawm ntawm kev sib tw thaum kuaj. Los ntawm 2013, kev siv quab qeeb-flex circuits nyob rau hauv cov neeg lag luam laptop computers tam sim no paub. Rigid-sl boards yog nyob rau hauv kev sib txuam ntau txheej txheem; Txawm li cas los xij, ob txheej hlau txheej txheem siv qee zaus.
