FPC

1.FPC-Flexible Printed Circuit Court, muaj kev txhim khu kev qha thiab hloov tau yooj yim luam tawm Circuit Court ua los ntawm etching rau tooj liab ntawv ci siv polyester zaj duab xis los yog polyimide ua lub substrate los tsim ib lub voj voog.

2.Product yam ntxwv: ① me me thiab lub teeb yuag: ua tau raws li qhov xav tau ntawm high-density, miniaturization, lub teeb yuag, thinness thiab siab kev txhim kho cov lus qhia; ② Kev hloov pauv siab: tuaj yeem txav mus los thiab nthuav dav hauv 3D qhov chaw, ua tiav kev sib koom ua ke ntawm cov khoom sib dhos thiab cov xaim txuas.

FPC daim ntawv thov:

lub koob yees duab, yees duab yees, CD-ROM, DVD, hard drive, laptop, xov tooj, xov tooj ntawm tes, tshuab luam ntawv, fax tshuab, TV, khoom siv kho mob, automotive electronics, aerospace thiab tub rog khoom.

Raws li tus naj npawb ntawm cov txheej txheem conductive, nws tuaj yeem muab faib ua pawg thawj coj saib ib leeg, ob sab board thiab ntau txheej txheej.

Ib sab board: tus neeg xyuas pib ntawm ib sab nkaus xwb

Ob chav sab board: muaj 2 conductors ntawm ob sab, thiab tsim hluav taws xob kev twb kev txuas ntawm 2 conductors nrog los ntawm lub qhov (ntawm) raws li ib tug choj. Ib los ntawm lub qhov yog ib qho me me tooj liab plated qhov ntawm lub qhov phab ntsa uas tuaj yeem txuas nrog cov circuits ntawm ob sab.

Multi-layer board: muaj 3 lossis ntau txheej ntawm cov neeg xyuas pib, nrog cov txheej txheem ntau dua.

Tsuas yog ib sab ntawm lub rooj tsavxwm, tus naj npawb ntawm cov txheej txheem nruj yog feem ntau txawm tias, xws li 2, 4, 6, 8 txheej, feem ntau yog vim qhov khib txheej txheej txheej txheej yog asymmetric thiab nquag ua rau board warping. Ntawm qhov tod tes, hloov pauv PCB yog qhov sib txawv vim tsis muaj teeb meem ntawm warping, yog li 3-txheej, 5-txheej, thiab lwm yam.

Copper foil yog muab tso rau hauv Electro-Deposited tooj liab (ED Copper) thiab Rolled Annealed tooj liab (RA Copper)

1oz 35 ua

OZ yog qhov hnyav, sib npaug rau 1/16 phaus, kwv yees li 28.35g.

Hauv kev lag luam Circuit Court board, lub thickness ntawm 1oz tooj liab nteg nyob rau hauv ib tug wquare ko taw yog txhais raws li 1oz. Yog li qee zaum cov neeg thov rau 28.35g ntawm tooj liab, peb yuav tsum tam sim ntawd paub tias qhov no yog qhov yuav tsum tau rau 1oz ntawm tooj liab.

Kev ua haujlwm ntawm lub npog ntsej muag: ① rwb thaiv tsev ② tiv thaiv Circuit Court thiab tiv thaiv kev puas tsuaj rau lub voj voog ③ tiv thaiv cov khoom txawv teb chaws los ntawm kev ua tsis tau rau hauv Circuit Court thiab ua rau luv luv Circuit Court.

Muaj 2 hom ntawm cov ntaub ntawv npog ntsej muag: number case thiab coverlay

Tus cwj mem siv rau daim npog ntsej muag yog feem ntau photosensitive thiab hu ua kua duab imagealble, abbreviated li LPI. Feem ntau muaj nyob rau hauv ntsuab, dub, dawb, liab, daj, xiav, thiab lwm yam.

Coverlay, feem ntau muaj xim daj (qee yam hu ua amber), dub thiab dawb. Dub muaj qhov muag pom zoo thiab dawb muaj qhov cuam tshuam siab, uas tuaj yeem hloov cov cwj mem dawb rau backlight saj zawg zog boards.

Nyob rau hauv rooj plaub ntawm lub rooj tsavxwm hloov tau, ob qho tib si number case thiab coerlay tuaj yeem siv rau daim npog ntsej muag. Yog li dab tsi yog qhov sib piv ntawm qhov zoo thiab qhov tsis zoo ntawm ob? Thov xa mus rau lub rooj hauv qab no:

Kev ua haujlwm ntawm qhov chaw tiav yog los tiv thaiv tooj liab nto oxidation, muab vuam los yog txheej txheej.

Feem ntau muaj ntau txoj kev ua tiav saum npoo raws li hauv qab no: specification rau nto tiav.

OSP: Organic solderability preservatives OSP: 0.2-0.5um

Plating Ni/Au Plating Tin: 4-20um

ENIG: Electroless Nickel Immersion Kub ENIG: 0.05-0.1um

Plating Sn / Tin Plating kub: 0.1-1um

Immersion Sn / Tin Immersion Tin: 0.3-1.2um

Immersion Ag Immersion Ag: 0.07-0.2um.

Tus nqi sib piv: Plating Ni/Au(ENIG) > Immersion Ag > Plating Sn/Tin (Immersion Sn/Tin) > OSP.

Tsis zoo li lub rooj tsavxwm nruj, lub rooj tsavxwm hloov tau tsis muaj qhov nruj thiab lub zog ua haujlwm zoo li lub rooj tsavxwm nruj, yog li nws tsis tuaj yeem kho tau zoo los ntawm cov ntsia hlau lossis ntxig daim npav. Feem ntau, nws yog ib qho tsim nyog los kho nws ntawm lub cuab yeej nrog ob-sided nplaum nplaum los tiv thaiv FPC los ntawm kev co tom qab sib dhos. Tsis tas li ntawd, ob-sided nplaum kuj tuaj yeem siv los txuas stiffener rau FPC.

DST (Ob-Sided Daim Kab Xev), tseem hu ua Pressure-Sensitive Adhesive (PSA), yog ob-sided nplaum nplaum siv rau FPC.

Siab Sensitive Adhesive tuaj yeem muab faib ua cov nplaum zoo tib yam, kub-kub resistant nplaum, conductive nplaum thiab thermal conductive nplaum.

Ordinary adhesives muaj xws li 3M467,3M468, conductive adhesives muaj xws li 3M9703,3M9713

Thermal conductive adhesives muaj xws li 3M8805,3M9882

High-temperature resistant nplaum yog hais txog cov nplaum uas tuaj yeem tiv taus SMT qhov kub thiab txias rau lub sijhawm luv luv, siv rau cov laug cam uas xav tau SMT mounting. Feem ntau siv cov nplaum muaj xws li 3M9460, 3M9077, 3M9079, TESA8853, thiab lwm yam.

Muaj ntau ntau hom stiffeners raws li hauv qab no:

Stainless Hlau (SS): Qee cov neeg siv khoom qhia SUS ntawm lawv cov duab kos, tab sis qhov tseeb, qhov no yog steel stiffener. SUS yog ib hom kev siv cov ntawv hlau.

AL: Aluminium

FR4

Polyimide

Polyester

Electro-Magnetic Interference (EMI) yog ib qho tshwm sim, tshwj xeeb tshaj yog nyob rau hauv high-frequency circuits, los xyuas kom meej lub meej mom ntawm lub teeb liab tsis distortion, electromagnetic shielding yog tsim nyog.Cov ntaub ntawv siv rau electromagnetic shielding ntawm FPC mas muaj xws li nyiaj number case thiab nyiaj number case zaj duab xis.

Silver number case yog ib yam khoom zoo li paste nrog cov xim hlau nyiaj thiab cov resin. Nws tuaj yeem luam tawm ntawm FPC zoo li cov ntawv lo lo ntxhuav hauv lub rooj tsavxwm nruj, thiab tom qab ntawd ci thiab khov kho. Txhawm rau tiv thaiv oxidation ntawm cov nyiaj hauv huab cua, ib txheej ntawm tus cwj mem los yog cov yeeb yaj kiab tiv thaiv feem ntau yog luam tawm ntawm tus lej nyiaj rau kev tiv thaiv.

Cov pwm siv feem ntau muab faib ua riam pwm thiab steel pwm. Qhov tseeb ntawm riam pwm yog qhov tsawg, nrog rau kev ua siab ntev txog +/- 0.3mm. Qhov tseeb ntawm steel pwm yog siab, nrog cov pwm zoo tib yam steel pwm txog +/-0.1mm thiab precision steel pwm mus txog +/-0.05mm. Qhov ua rau tus nqi ntawm steel pwm yog ob peb lossis txawm kaum lub sij hawm ntawm riam pwm.

Riam pwm kuj hu ua cov cuab yeej mos, thiab cov pwm hlau kuj hu ua cov cuab yeej nyuaj.

Siv cov cuab yeej tshuaj xyuas hluav taws xob kom muaj zog tag nrho ntawm cov khoom los xyuas qhov tsis xws luag xws li qhib, luv luv, thiab lwm yam hauv cov khoom circuits. Nyob rau hauv lub sij hawm sampling, qhov kom muaj nuj nqis yog me me, thiaj li yuav txuag tau tus nqi ntawm qhib ib tug xeem ncej, ya soj ntsuam yog siv rau kev sim. Txawm li cas los xij, kev sojntsuam ya davhlau yog qhov nyuaj thiab siv sijhawm ntev uas ua rau muaj kev ua haujlwm tsawg. Yog li ntawd, kev ntsuam xyuas yog ua los ntawm kev sim thav duab (fixture, jig) thaum lub sij hawm ntau lawm.

Qhov tsis xws luag tuaj yeem pom thaum kuaj hluav taws xob muaj xws li: yam khoom; qhib; luv.

Kev ceev faj yuav tsum tau them rau qhov tshwm sim ntawm qhov tsis xws luag thaum kuaj hluav taws xob: khawb ntawm qhov chaw tiav qhov tshwm sim los ntawm kev soj ntsuam hluav taws xob

Ua ib qho kev tshuaj ntsuam xyuas ntawm tus kheej cov khoom tiav raws li cov qauv tshuaj ntsuam xyuas

Muaj ntau txoj kev tshuaj xyuas raws li qhov sib txawv ntawm cov khoom raws li hauv qab no:

① Kev tshuaj xyuas qhov muag

② kev tshuaj xyuas microscopic (tsawg kawg 10X)

Feem ntau tshuaj xyuas cov tsos, suav nrog khawb, dents, wrinkles, oxidation, blistering, solder mask misalignment, drilling misalignment, circuit gaps, residual tooj liab, txawv teb chaws khoom, thiab lwm yam.
