PCBA conformal txheej txau txheej txheem ntws

Raws li cov neeg siv khoom xav tau, Cirket kuj muaj cov txheej txheem txheej txheem.PCBA conformal txheej tau zoo heev rwb thaiv tsev, ya raws-pov thawj, to-proof, shock-proof, plua plav-pov thawj, corrosion-proof, anti-aging, mildew-proof, anti-ib feem. loosening thiab rwb thaiv tsev corona tiv thaiv cov khoom, uas tuaj yeem txuas ntxiv lub sijhawm cia ntawm PCBA. Cirket yog ib txwm siv Txau uas kuj yog cov txheej txheem siv ntau tshaj plaws hauv kev lag luam.

Cirket PCBA conformal txheej txau txheej txheem ntws

1. Cov cuab yeej tsim nyog

Conformal txheej xim, pleev xim lub thawv, hnab looj tes roj hmab, daim npog qhov ncauj lossis lub npog ntsej muag, txhuam, daim nplaum nplaum, tweezers, cov khoom siv cua tshuab, ziab khaub ncaws thiab qhov cub.

2. Txau cov kauj ruam

Painting A sab → nto ziab → pleev xim B sab → kho nyob rau hauv chav tsev kub

3. Cov txheej txheem txheej txheem

(1) Ntxuav thiab qhuav lub rooj tsavxwm kom tshem tawm cov dej noo thiab dej ntawm PCBA. Cov plua plav, noo noo thiab roj nyob rau saum npoo ntawm PCBA yuav tsum tau coated yuav tsum tau muab tshem tawm ua ntej kom lub txheej muaj peev xwm ua tau tag nrho nws cov kev tiv thaiv. Kev tu kom huv tuaj yeem ua kom ntseeg tau tias cov corrosive residues raug tshem tawm tag nrho thiab cov txheej txheem conformal adheres zoo rau saum npoo ntawm lub rooj tsavxwm. Ci tej yam kev mob: 60 ° C, 10-20 feeb. Cov nyhuv zoo tshaj plaws rau txheej yog txau thaum lub rooj tsavxwm kub tom qab raug tshem tawm ntawm qhov cub.

(2) Thaum txhuam cov txheej txheem txheej, qhov txheej txheej yuav tsum loj dua qhov chaw nyob ntawm cov khoom kom ntseeg tau tias tag nrho cov khoom thiab cov ntaub qhwv npog.

(3) Thaum txhuam cov txheej txheem, lub rooj tsav xwm hauv Circuit Court yuav tsum tau muab tso rau hauv lub tiaj li sai tau. Yuav tsum tsis muaj dej ntws tom qab txhuam hniav. Cov txheej yuav tsum du thiab yuav tsum tsis txhob muaj qhov cuam tshuam. Lub thickness yuav tsum yog 0.1-0.3 hli.

(4) Ua ntej txhuam los yog txau cov txheej txheem txheej, cov neeg ua haujlwm Cirket xyuas kom cov txheej txheej txheej txheej txheej txheej yog nplawm thiab sab laug rau 2 teev ua ntej txhuam los yog txau. Siv cov txhuam hniav zoo nkauj zoo nkauj los txhuam thiab txhuam hauv chav sov. Yog tias siv lub tshuab, lub viscosity ntawm cov txheej yuav tsum tau ntsuas (siv lub viscosity tester lossis flow cup) thiab viscosity tuaj yeem hloov kho nrog diluent.

• Cov khoom siv hluav taws xob hauv Circuit Court yuav tsum muab tso rau hauv vertically hauv lub tank txheej tsawg kawg ib feeb kom txog thaum cov npuas ploj thiab maj mam tshem tawm. Thov nco ntsoov tias cov connectors yuav tsum tsis txhob muab tso rau hauv tshwj tsis yog tias lawv ua tib zoo npog. Ib zaj duab xis zoo ib yam yuav tsim rau ntawm qhov chaw ntawm lub rooj tsavxwm. Feem ntau ntawm cov xim residue yuav tsum ntws rov qab los ntawm Circuit Court board mus rau lub tshuab dipping. TFCF muaj cov txheej txheem sib txawv. Qhov ceev ntawm dipping lub rooj tsavxwm los yog cov khoom siv yuav tsum tsis txhob ceev heev kom tsis txhob muaj npuas ntau dhau.

(6) Yog tias muaj cov pob zeb nyob rau saum npoo thaum siv nws dua tom qab dipping, tshem tawm cov tawv nqaij thiab siv nws ntxiv.

(7) Tom qab txhuam hniav, muab lub rooj tsav xwm hauv Circuit Court tiaj tus ntawm lub bracket thiab npaj rau kev kho. Nws yog ib qho tsim nyog yuav tsum tau ua kom sov kom ceev cov txheej txheem kho. Yog hais tias lub txheej txheej yog tsis sib npaug los yog muaj npuas, nws yuav tsum tau muab tso rau hauv lub chav tsev kub rau lub sij hawm ntev ua ntej kho nyob rau hauv ib tug kub-kub rauv kom cov kuab tshuaj mus flash.

Cov kev ceev faj

1. Thaum lub sij hawm cov txheej txheem txau, qee yam tsis tuaj yeem txau, xws li: lub zog hluav taws xob kub dissipation nto los yog cov khoom siv hluav taws xob, lub zog hluav taws xob, lub zog diodes, cement resistors, dip keyboards, adjustable resistors, buzzers, cov tuav roj teeb, fuse tuav ( raj), IC tuav, kov keyboards, thiab lwm yam.

2. Nws yog txwv tsis pub muab cov xim peb-pov thawj ntxiv rau hauv lub thawv ntim khoom qub. Nws yuav tsum tau muab cais thiab kaw.

3. Yog tias chav ua haujlwm lossis chav cia khoom kaw rau lub sijhawm ntev (ntau tshaj 12 teev), tso pa tawm rau 15 feeb ua ntej nkag mus.

4. Yog hais tias nws tsoo lub tsom iav, thov qhib lub qhov muag sab sauv thiab sab qis tam sim ntawd thiab yaug nrog dej los yog dej ntsev, thiab tom qab ntawd nrhiav kev kho mob.
