Cov ntaub ntawv dab tsi yog siv rau hauv rigid-flex Boards?

Ib hom Circuit Court board uas tau nrov zuj zus hauv kev lag luam hluav taws xob yog qhovrigid-flex board.

Thaum nws los txog rau cov khoom siv hluav taws xob xws li smartphones thiab laptops, cov kev ua haujlwm sab hauv yog ib qho tseem ceeb raws li qhov stylish sab nrauv. Cov khoom siv uas ua rau cov cuab yeej no ua haujlwm feem ntau muab zais hauv qab cov txheej txheem Circuit Court kom ntseeg tau tias lawv ua haujlwm thiab ua haujlwm ntev. Tab sis dab tsi cov ntaub ntawv siv nyob rau hauv cov tshiab Circuit Court boards?

Rigid-flex PCBcombines qhov zoo ntawm nruj thiab yooj ywm Circuit Court boards, muab ib tug tshwj xeeb kev daws teeb meem rau cov khoom uas yuav tsum tau ib tug ua ke ntawm mechanical zog thiab yooj. Cov boards no muaj txiaj ntsig tshwj xeeb hauv cov ntawv thov uas cuam tshuam nrog kev tsim peb-dimensional lossis cov khoom siv uas yuav tsum tau nquag folding lossis khoov.

Cia peb saib ze dua ntawm cov khoom siv feem ntau siv hauv kev tsim kho rigid-flex PCB:

1. FR-4: FR-4 yog cov nplaim hluav taws-retardant iav-reinforced epoxy laminate khoom siv dav hauv kev lag luam hluav taws xob. Nws yog cov khoom siv feem ntau siv hauv cov khoom siv tawv-flex PCBs. FR-4 muaj cov khoom siv hluav taws xob zoo heev thiab cov khoom siv zoo, ua rau nws zoo tagnrho rau cov ntu ntu ntawm cov rooj sib tham.

2. Polyimide: Polyimide yog cov khoom siv hluav taws xob kub-resistant polymer uas feem ntau siv los ua cov khoom siv hauv cov khoom siv hauv cov rigid-flex boards. Nws muaj cov thermal stability zoo heev, hluav taws xob rwb thaiv tsev cov khoom thiab cov neeg kho tshuab hloov tau yooj yim, tso cai rau nws tuaj yeem rov kho dua thiab khoov yam tsis muaj kev cuam tshuam rau kev ncaj ncees ntawm lub rooj tsav xwm Circuit Court.

3. Copper: tooj liab yog cov khoom siv tseem ceeb hauv cov rigid-flex boards. Nws yog siv los tsim cov kab hluav taws xob thiab kev sib txuas uas tso cai rau cov hluav taws xob tam sim no ntws ntawm cov khoom ntawm lub rooj tsav xwm hauv Circuit Court. Tooj liab yog nyiam vim nws cov conductivity siab, zoo solderability thiab nqi-zoo.

4. Adhesive: Adhesive yog siv los khi cov txheej txheem nruj thiab hloov pauv ntawm PCB ua ke. Nws yog ib qho tseem ceeb los xaiv cov nplaum uas tuaj yeem tiv taus cov thermal thiab mechanical stresses thaum lub sij hawm tsim khoom thiab khoom siv lub neej. Thermoset adhesives, xws li epoxy resins, feem ntau yog siv rau hauv rigid-flex PCBs vim lawv cov khoom zoo heev thiab kub ua hauj.

5. Coverlay: Coverlay yog txheej tiv thaiv siv los npog qhov hloov pauv ntawm lub rooj tsav xwm hauv Circuit Court. Nws feem ntau yog tsim los ntawm polyimide los yog cov khoom siv sib xws thiab siv los tiv thaiv cov kab mob me me thiab cov khoom siv los ntawm ib puag ncig xws li ya raws thiab plua plav.

6. Lub npog ntsej muag: Lub npog ntsej muag yog ib txheej tiv thaiv coated ntawm qhov nruj ntawm PCB. Nws pab tiv thaiv kev sib txuas thiab hluav taws xob luv luv thaum tseem muab cov rwb thaiv tsev thiab tiv thaiv corrosion.

Cov no yog cov ntaub ntawv tseem ceeb uas siv rau hauv kev tsim kho PCB nruj.Txawm li cas los xij, nws tsim nyog sau cia tias cov ntaub ntawv tshwj xeeb thiab lawv cov khoom yuav txawv nyob ntawm lub rooj tsavxwm daim ntawv thov thiab kev ua haujlwm xav tau. Cov neeg tsim khoom feem ntau hloov kho cov ntaub ntawv siv hauv cov khoom nruj-flex PCBs kom tau raws li cov kev cai tshwj xeeb ntawm cov cuab yeej uas lawv tau siv.

Hauv cov ntsiab lus,rigid-flex PCBs yog ib qho kev tsim kho tshiab zoo tshaj plaws hauv kev lag luam hluav taws xob, muab kev sib xyaw ua ke ntawm cov neeg kho tshuab lub zog thiab yoog raws. Cov ntaub ntawv siv xws li FR-4, polyimide, tooj liab, adhesives, overlays, thiab solder qhov ncauj qhov ntswg tag nrho ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm thiab ua haujlwm ntev ntawm cov laug cam. Los ntawm kev nkag siab txog cov ntaub ntawv siv hauv cov khoom siv nruj-flex PCBs, cov tuam ntxhab thiab cov neeg tsim khoom tuaj yeem tsim cov khoom siv hluav taws xob zoo, txhim khu kev qha uas ua tau raws li qhov xav tau ntawm lub ntiaj teb kev siv tshuab niaj hnub no.
