Cov ntaub ntawv luam tawm yooj yim |Polyimide Pcb |Tooj Pcb |Soldering Circuit Boards

Hauv kab lus no, peb yuav ua tib zoo saib cov ntaub ntawv uas nquag siv hauvflexible printed circuit manufacturing.

Flexible printed circuits (FPC) tau hloov pauv ntawm cov khoom siv hluav taws xob.Lawv lub peev xwm khoov ua rau lawv nrov hauv ntau yam kev lag luam xws li aerospace, tsheb, kev kho mob, thiab cov khoom siv hluav taws xob.

Ib qho ntawm cov ntaub ntawv tseem ceeb siv hauv kev tsim cov ntawv luam tawm yooj yim yog polyimide.Polyimide yog ib qho kev ua tau zoo polymer nrog zoo heev thermal stability, tshuaj tsis kam thiab mechanical toughness.Cov khoom no ua rau nws zoo tagnrho rau kev hloov pauv hloov pauv raws li nws tuaj yeem tiv taus qhov kub thiab txias ib puag ncig yam tsis muaj kev cuam tshuam rau nws txoj haujlwm.Polyimide-raws li cov yeeb yaj kiab feem ntau yog siv los ua cov substrates rau cov ntawv luam tawm yooj yim.

Ntxiv nrog rau polyimide, lwm yam khoom siv feem ntau siv hauv kev lag luam luam tawm yooj yim yog tooj liab.Copper tau raug xaiv rau nws cov khoom siv hluav taws xob zoo heev, tiv thaiv corrosion thiab ductility.Nyias tooj liab ntawv ci feem ntau yog laminated rau polyimide substrate los tsim txoj kev conductive rau lub voj voog.Cov txheej tooj liab muab cov khoom siv hluav taws xob sib txuas uas tsim nyog rau lub voj voog kom ua haujlwm zoo.

Txhawm rau tiv thaiv cov kab tooj liab thiab ua kom lub neej ntev ntawm cov ntawv luam tawm yooj yim, yuav tsum muaj txheej txheej npog lossis daim npog ntsej muag.Overlay yog ib qho thermoset nplaum zaj duab xis feem ntau siv rau qhov chaw hauv Circuit Court.Nws ua raws li cov txheej txheem tiv thaiv, tiv thaiv cov kab tooj liab los ntawm ib puag ncig xws li ya raws, plua plav, thiab kev puas tsuaj rau lub cev.Cov khoom siv npog feem ntau yog polyimide-raws li zaj duab xis, uas muaj lub zog sib txuas siab thiab tuaj yeem ruaj khov rau polyimide substrate.

Txhawm rau txhim kho kev ua haujlwm ntev thiab ua haujlwm ntawm cov ntawv luam tawm yooj yim, cov ntaub ntawv txhawb nqa xws li daim kab xev lossis cov ntaub ntawv txhawb zog feem ntau siv.Ntxiv cov kev txhawb zog rau cov cheeb tsam tshwj xeeb ntawm ib lub voj voog uas xav tau lub zog ntxiv los yog khov kho.Cov ntaub ntawv no tuaj yeem suav nrog ntau yam kev xaiv, xws li polyimide lossis polyester zaj duab xis, fiberglass, lossis cov ntawv hlau.Kev txhawb zog pab tiv thaiv kev sib tsoo los ntawm kev tawg lossis tawg thaum txav los yog ua haujlwm.

Tsis tas li ntawd, cov ntaub qhwv los yog cov neeg sib txuas tau ntxiv los pab txhawb kev sib txuas ntawm cov ntawv luam tawm yooj yim thiab lwm yam khoom siv hluav taws xob.Cov ntaub qhwv no feem ntau yog tsim los ntawm kev sib xyaw ntawm tooj liab thiab cov khoom siv tawv-resistant.Bonding pads muab qhov tsim nyog interface rau soldering lossis txuas cov khoom xws li kev sib xyaw ua ke (ICs), resistors, capacitors, thiab connectors.

Ntxiv nrog rau cov ntaub ntawv tseem ceeb saum toj no, lwm yam khoom tseem tuaj yeem ntxiv thaum lub sijhawm tsim khoom raws li cov kev xav tau tshwj xeeb.Piv txwv li, cov nplaum tuaj yeem siv los ua cov txheej txheem sib txawv ntawm cov ntawv luam tawm yooj yim ua ke.Cov nplaum no ua kom muaj kev ruaj khov thiab txhim khu kev qha, tso cai rau lub voj voog kom tswj tau nws cov qauv kev ncaj ncees.Silicone adhesives feem ntau siv vim lawv qhov yooj yim, kub tsis kam, thiab cov khoom sib txuas zoo heev.

Zuag qhia tag nrho, cov ntaub ntawv siv hauv kev tsim cov ntawv luam tawm yooj yim yog ua tib zoo xaiv los ua kom pom kev ua haujlwm zoo thiab ua haujlwm ntev.Kev sib xyaw ua ke ntawm polyimide ua ib lub substrate, tooj liab rau conductivity, overlays rau kev tiv thaiv, cov ntaub ntawv ntxiv rau lub zog ntxiv, thiab cov ntaub qhwv rau cov khoom sib txuas tsim ib qho kev txhim khu kev qha thiab ua tiav cov ntawv luam tawm yooj yim.Lub peev xwm ntawm cov kab hluav taws xob no hloov mus rau ntau yam kev siv, suav nrog cov npoo nkhaus thiab qhov chaw nruj, ua rau lawv tsis muaj qhov tseem ceeb hauv cov khoom siv hluav taws xob niaj hnub no.

Hauv cov ntsiab lus, cov ntaub ntawv luam tawm yooj yim xws li polyimide, tooj liab, overlays, reinforcements, adhesives, thiab pads yog cov khoom tseem ceeb hauv kev tsim cov khoom siv hluav taws xob ruaj khov thiab hloov tau yooj yim.Cov ntaub ntawv no ua haujlwm ua ke los muab cov kev sib txuas hluav taws xob tsim nyog, kev tiv thaiv thiab lub zog siv hluav taws xob xav tau hauv cov khoom siv hluav taws xob niaj hnub no.Raws li kev siv thev naus laus zis txuas ntxiv mus, cov ntaub ntawv siv hauv cov khoom siv hluav taws xob hloov pauv hloov pauv yuav hloov zuj zus ntxiv, ua kom muaj kev siv tshiab tshiab.
