Yuav ua li cas daws qhov teeb meem ntawm PCB pawg thawj coj saib tooj liab clad laminate

Nov yog qee qhov feem ntau ntsib teeb meem PCB Circuit Board thiab yuav ua li cas kom paub meej lawv. Thaum koj ntsib teeb meem PCB laminate, koj yuav tsum xav txog ntxiv nws rau PCB laminate khoom specification. Cov hauv qab no piav qhia yuav ua li cas los daws qhov teeb meem ntawm PCB Circuit board tooj liab clad laminate?

PCB Circuit board tooj liab clad laminate teeb meem ib. Yuav tau taug qab thiab nrhiav tau

Nws yog tsis yooj yim sua los tsim ib tug xov tooj ntawm PCB Circuit Court boards yam tsis tau ntsib tej teeb meem, uas yog feem ntau ntaus nqi rau cov khoom ntawm PCB tooj liab clad laminate. Thaum cov teeb meem zoo tshwm sim hauv cov txheej txheem tsim khoom tiag tiag, nws zoo li feem ntau vim tias cov khoom siv PCB substrate dhau los ua qhov teeb meem. Txawm tias ua tib zoo sau thiab xyaum siv PCB laminate technical specification tsis qhia cov khoom kuaj uas yuav tsum tau ua los txiav txim siab tias PCB laminate yog qhov ua rau muaj teeb meem ntawm cov txheej txheem tsim khoom. Nov yog qee qhov feem ntau ntsib teeb meem PCB laminate thiab yuav ua li cas txheeb xyuas lawv.

Thaum koj ntsib teeb meem PCB laminate, koj yuav tsum xav txog ntxiv nws rau PCB laminate khoom specification. Feem ntau, yog tias qhov kev qhia tshwj xeeb no tsis ua tiav, nws yuav ua rau muaj kev hloov pauv tsis tu ncua thiab ua rau cov khoom seem. Feem ntau, cov khoom siv teeb meem tshwm sim los ntawm kev hloov pauv ntawm qhov zoo ntawm PCB laminates tshwm sim hauv cov khoom tsim los ntawm cov tuam txhab siv cov khoom sib txawv ntawm cov khoom siv raw lossis siv cov khoom sib txawv. Tsawg tus neeg siv muaj cov ntaub ntawv txaus kom paub qhov txawv ntawm cov xovxwm tshwj xeeb lossis cov khoom siv ntawm qhov chaw ua haujlwm. Raws li qhov tshwm sim, nws feem ntau tshwm sim tias PCBs tau txuas ntxiv tsim thiab txuas nrog cov khoom sib txuas, thiab cov warps txuas ntxiv tsim nyob rau hauv lub tank solder, uas ua rau cov khoom siv tsis zoo thiab cov khoom kim heev. Yog tias tus lej batch ntawm cov khoom thauj khoom tuaj yeem pom tam sim ntawd, PCB laminate chaw tsim tshuaj paus tuaj yeem txheeb xyuas cov batch tooj ntawm cov resin, batch tooj ntawm cov ntawv ci tooj liab, thiab lub voj voog kho. Hauv lwm lo lus, yog tias tus neeg siv tsis tuaj yeem muab kev txuas ntxiv nrog kev tswj hwm zoo ntawm PCB laminate chaw tsim khoom, qhov no yuav ua rau tus neeg siv nws tus kheej raug kev puas tsuaj mus ntev. Cov hauv qab no qhia txog cov teeb meem dav dav ntsig txog cov ntaub ntawv substrate hauv PCB Circuit Board tsim txheej txheem.

Cov tsos mob: tsis zoo luam tawm adhesion, tsis zoo plating adhesion, qee qhov tsis tuaj yeem etched, thiab qee qhov tsis tuaj yeem soldered.

Muaj txoj hauv kev tshuaj xyuas: feem ntau yog siv los tsim cov kab dej pom ntawm qhov chaw ntawm lub rooj tsavxwm rau kev tshuaj xyuas qhov muag:

yog vim li cas:

Vim tias qhov ntom ntom ntom ntom ntom ntom ntom thiab du tsim los ntawm cov yeeb yaj kiab tso tawm, cov xim tsis muaj tooj liab yog ci dhau lawm.

Feem ntau nyob rau sab uncoppered ntawm lub laminate, cov chaw tsim tshuaj paus laminate tsis tshem tawm tus neeg sawv cev tso tawm.

Cov pinholes nyob rau hauv cov ntawv ci tooj liab ua rau cov resin ntws tawm thiab sib sau ua ke ntawm cov ntawv ci tooj liab. Qhov no feem ntau tshwm sim ntawm cov ntawv ci tooj liab uas yog nyias dua li 3/4 ounce qhov hnyav specification.

Copper foil chaw tsim tshuaj paus coats saum npoo ntawm cov ntawv ci tooj liab nrog ntau cov tshuaj antioxidants.

Cov chaw tsim khoom laminate hloov cov txheej txheem resin, stripping nyias, los yog txhuam txoj kev.

Vim yog kev ua haujlwm tsis raug, muaj ntau cov ntiv tes lossis cov roj stains.

Dip nrog lub cav roj thaum lub sij hawm xuas nrig ntaus, blanking lossis drilling ua haujlwm.

Daws daws tau:

Ua ntej ua kev hloov pauv hauv kev tsim laminate, koom tes nrog cov chaw tsim khoom laminate thiab qhia cov neeg siv cov khoom kuaj.

Nws raug pom zoo tias cov tuam txhab laminate siv cov ntaub zoo li cov yeeb yaj kiab lossis lwm cov ntaub ntawv tso tawm.

Hu rau lub chaw tsim khoom laminate los tshuaj xyuas txhua pawg ntawm cov ntawv ci tooj liab uas tsis tsim nyog; nug txog kev pom zoo rau kev tshem tawm cov resin.

Nug lub chaw tsim khoom laminate rau txoj kev tshem tawm. Changtong pom zoo kom siv hydrochloric acid, ua raws li cov neeg kho tshuab txhuam kom tshem tawm nws.

Hu rau lub chaw tsim khoom laminate thiab siv cov txheej txheem tshem tawm cov tshuab lossis tshuaj lom neeg.

Qhia cov neeg ua haujlwm hauv txhua qhov txheej txheem kom hnav hnab looj tes los tuav tooj liab clad laminates. Tshawb xyuas seb lub laminate raug xa nrog lub ncoo haum lossis ntim rau hauv lub hnab, thiab lub ncoo muaj cov ntsiab lus tsis tshua muaj leej faj, thiab lub hnab ntim khoom tsis muaj av. Ua tib zoo xyuas kom tsis muaj leej twg kov nws thaum siv cov tshuaj ntxuav tes uas muaj silicone tooj liab.

Degrease tag nrho cov laminates ua ntej plating lossis qauv hloov txheej txheem.
