Cov tooj liab tuab npaum li cas hauv PCBs hloov tau?

Thaum nws los txog rau PCBs hloov tau (cov ntawv luam tawm Circuit Court boards), ib qho ntawm cov ntsiab lus tseem ceeb yuav tsum xav txog yog qhov tuab ntawm tooj liab. Tooj liab ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm thiab ua haujlwm ntawm cov PCB hloov tau yooj yim thiab yog li qhov tseem ceeb kom nkag siab.Nyob rau hauv no blog ncej, peb mam li delve tob rau hauv lub ntsiab lus ntawm tooj liab thickness nyob rau hauv saj zawg zog PCBs, thiab Shenzhen Capel Technology Co., Ltd. txhawb tooj liab thinness, sib tham txog nws qhov tseem ceeb thiab yuav ua li cas nws cuam tshuam rau tag nrho cov kev ua tau zoo ntawm lub rooj tsavxwm.

Qhov tseem ceeb ntawm tooj liab thickness nyob rau hauv saj zawg zog PCB

Tooj liab yog thawj qhov kev xaiv rau PCBs vim nws cov hluav taws xob zoo heev thiab kev tiv thaiv corrosion.Hauv kev hloov pauv ntawm PCBs, tooj liab yog siv los ua cov khoom siv hluav taws xob uas tso cai rau hluav taws xob tam sim no ntws los ntawm lub voj voog. Lub thickness ntawm tooj liab ncaj qha cuam tshuam rau kev ua haujlwm thiab kev ua haujlwm ntawm lub PCB hloov tau. Ntawm no yog vim li cas tooj liab thickness tseem ceeb:

1. Lub peev xwm nqa tam sim no: Lub thickness ntawm tooj liab txiav txim siab npaum li cas tam sim no PCB tuaj yeem nqa tau yam tsis muaj cua sov lossis ua rau muaj teeb meem hluav taws xob.Cov khaubncaws sab nraud povtseg tuab tuaj yeem ua haujlwm zoo dua tam sim no, kom ntseeg tau tias kev ua haujlwm zoo ntawm flex Circuit Court.

2. Teeb liab kev ncaj ncees: Flexible PCBs feem ntau yog siv rau hauv cov ntawv thov uas xav tau cov teeb liab siab ncaj ncees, xws li aerospace, khoom siv kho mob, thiab kev sib txuas lus.Copper thickness cuam tshuam rau impedance ntawm cov kab, kom ntseeg tau tias cov teeb liab propagate kom raug nrog tsawg tsawg los yog distortion.

3. Mechanical Strength: Cov ntaub ntawv luam tawm yooj yim yog tsim los hloov tau, uas txhais tau hais tias lawv raug khoov tas li, twisting thiab flexing.Cov txheej tooj liab muab cov khoom siv dag zog rau lub voj voog thiab tiv thaiv cov kab nrib pleb lossis tawg hauv cov kev coj ua. Lub thickness tooj liab txaus ua kom ntseeg tau tias PCB tseem muaj zog thiab ruaj khov nyob rau hauv nws lub neej.

Kawm txog kev ntsuas tooj liab thickness

Hauv lub ntiaj teb hloov pauv PCB, tooj liab tuab feem ntau ntsuas hauv ounces ib square feet (oz / ft²) lossis micrometers (μm). Cov kev xaiv tooj liab ntau tshaj plaws rau kev hloov pauv PCBs yog 0.5 oz (17.5 µm), 1 oz (35 µm), 2 oz (70 µm), thiab 3 oz (105 µm). Qhov kev xaiv ntawm tooj liab thickness nyob ntawm qhov kev thov tshwj xeeb xws li lub peev xwm nqa tam sim no thiab lub zog txhua yam.

Yam cuam tshuam rau kev xaiv tooj liab thickness

Ntau yam cuam tshuam rau kev xaiv ntawm tooj liab tuab hauv ib qho yooj yim PCB, suav nrog:

1. Cov kev xav tau tam sim no: Cov ntawv thov tam sim no siab dua feem ntau xav tau cov txheej tooj liab tuab dua kom ntseeg tau tias muaj peev xwm nqa tau zoo.Kev txiav txim siab yuav tsum tau muab rau qhov siab tshaj plaws tam sim no lub Circuit Court yuav ntsib kom tsis txhob overheating ntawm tooj liab los yog overvoltage poob.

2. Qhov chaw txwv: Cov khoom siv me me, cov khoom siv me me tuaj yeem xav tau cov txheej tooj liab nyias kom haum rau qhov chaw muaj tsawg.Txawm li cas los xij, qhov kev txiav txim siab no yuav tsum tau ua tib zoo ntsuas tawm tsam tam sim no lub peev xwm nqa thiab lub zog siv tshuab.

3. Flexibility: Qhov yooj ntawm PCB cuam tshuam los ntawm tooj liab thickness.Thicker tooj liab txheej feem ntau nyuaj, txo qhov yooj yim ntawm lub voj voog. Rau cov ntawv thov hloov tau yooj yim, qis dua tooj liab thicknesses nyiam dua.

Manufacturing ceev faj

Flexible PCB manufacturing txheej txheem yog tsim los kom haum rau ntau yam ntawm tooj liab thicknesses. Txawm li cas los xij, qee qhov tooj liab thicknesses yuav xav tau kev ceev faj ntxiv lossis cov txheej txheem tshwj xeeb thaum lub sijhawm tsim khoom. Cov khaubncaws sab nraud povtseg tuaj yeem xav tau ntev etching lub sijhawm kom ua tau raws li qhov xav tau ntawm cov qauv, thaum cov khaubncaws sab nraud povtseg yuav tsum tau ua kom zoo dua kom tsis txhob muaj kev puas tsuaj thaum sib dhos.

Ua haujlwm ze nrog PCB cov chaw tsim khoom yog qhov tseem ceeb kom nkag siab txog cov kev txwv lossis kev txiav txim siab tshwj xeeb rau qhov xav tau tooj liab tuab. Qhov no ua kom cov txheej txheem tsim ua tiav yam tsis muaj kev cuam tshuam rau PCB kev ua haujlwm.

Shenzhen Capel Technology Co., Ltd. txhawb tooj liab thinness nyob rau hauv saj zawg zog pcb

Capel yog lub tuam txhab paub zoo uas tshwj xeeb hauv kev tsim cov ntawv luam tawm yooj yim thiab nkag siab txog qhov tseem ceeb ntawm tooj liab thickness rau tag nrho kev ua haujlwm thiab kev ua haujlwm ntawm cov ntawv luam tawm yooj yim.

Capel muaj nyob rau hauv 1/2 oz tooj liab tuab. Qhov kev ua tau zoo ntawm nws cov rigid-flex Circuit Court yog siab dua. Qhov no ua rau lub voj voog kom tau raws li cov kev xav tau ntawm cov ntawv thov muaj zog thaum tswj qhov tsim nyog yooj.

Membrane hloov:

Capel kuj tseem tsim cov khoom siv membrane nrog cov txheej tooj liab nyias nyias. Cov keyboards no tau siv dav hauv kev lag luam uas xav tau cov neeg siv interface daws teeb meem, xws li cov cuab yeej kho mob thiab kev tswj hwm kev lag luam. Lub thickness ntawm tooj liab ntawm cov membrane hloov li ntawm 0.005 "mus rau 0.0010". Ib txheej txheej ultra-nyias ntawm tooj liab ua kom lub zog hloov tau zoo heev thaum tswj xyuas qhov tsim nyog ruaj khov.

Kev xav zaum kawg:

Lub thickness ntawm tooj liab nyob rau hauv ib tug saj zawg zog PCB muaj ib tug tseem ceeb cuam tshuam rau nws cov kev ua tau zoo, kev cia siab rau thiab lub neej ntev. Xaiv qhov tsim nyog tooj liab tuab raws li qhov yuav tsum tau ua tam sim no, qhov chaw txwv, kev hloov pauv thiab kev tsim khoom yog qhov tseem ceeb. Kev sab laj nrog cov kws tshaj lij PCB cov tuam txhab tsim khoom thiab cov kws tshaj lij tsim qauv tuaj yeem pab txhim kho PCB hloov tau yooj yim rau ntau daim ntawv thov, ua kom lawv ua tau raws li cov qauv tsim hluav taws xob thiab kev ua haujlwm zoo.
