Hauv cov ntoo cog ntoo, yas feem ntau ua rau nws yog xim hlau ntawm qhov tso nyiaj. Qhov qauv no tsis muaj nyob hauv tsev. Qhov xav tau kom tau cov hlau tsis yog hlau qee zaus tshwm sim, tshwj xeeb tshaj yog rau cov neeg uas nyiam ntawm cov xov tooj cua hluav taws xob. Muaj ob txoj hauv kev pheej yig ntawm kev siv tshuaj hlau.
Thermal txoj kev nrog kua nplaum thiab ntawv ci
Yog tias koj xav ua tus PCB lossis metallize lwm qhov chaw tiaj tus hauv tsev, koj tuaj yeem khi cov yas rau cov ntawv ci thaum cua sov. Lub qhov cub tsis tu ncua yuav pab. Ua li no, koj yuav tsum:
- ib daim yas;
- tooj liab ntawv ci;
- kua nplaum BF-2 lossis BF-4;
- hnyav;
- clamps;
- tooj liab lossis ntoo paib;
- qhov cub lossis hlau.
Siv daim ntawv yas thiab so nws nrog cov kuab tshuaj. Kuj degrease cov ntawv ci ntawm ib sab koj yuav ua gluing. Ntub cov nplaim yas thiab ntawv ci nrog BF-2 lossis BF-4 kua nplaum thiab tuav kom ntev li ntev tau qhia hauv cov lus qhia. Muab ib daim ntawv ntawm ntawv ci ntawm daim yas. Nias nias kom tsis muaj cua npuas nruab nrab ntawm qhov chaw. Clamp lub workpiece nruab nrab ntawm cov ntoo lossis hlau siv clamps.
Tso tus qauv rau hauv qhov cub kom txog li 100 ° C thiab tawm mus li 20 feeb. Tig lub qhov cub, tshem tawm cov haujlwm tawm thiab tawm nws mus txias rau ib hnub. Tom qab ntawd, koj tuaj yeem ua tshuaj lom rau pawg thawj coj. Thaum tsis muaj lub qhov cub, koj tuaj yeem siv cov hlau los nias lub qhov khoob los ntawm ntawv ci sab rau nws nrog kev pab ntawm clamps.
Koj kuj tseem tuaj yeem siv dej xau lossis zawv plaub hau kom degrease.
Kev xaiv nrog tooj liab sulfate - da dej galvanic
Txhawm rau metallize nto nyob rau hauv txoj kev no, koj yuav tsum:
- Cov kua nplaum BF lossis nitrocellulose;
- aluminium hmoov;
- tsau dej cawv;
- sulfuric acid;
- tooj dag seem;
- roj teeb tsheb;
- tooj liab hlau;
- yas los yog enameled phiab;
- ntawv txiav.
Sib tov kua nplaum nrog txhuas hmoov kom txog thaum lub sib xws ntawm kua qaub cream. Thov ib txheej ntawm cov txiaj ntsig kom tshwm sim rau saum npoo ntawm cov yas thiab cia kom qhuav.
Yog tias cov kua nplaum lo tuab heev, los muab nws nrog cawv cuaj caum me ntsis.
Dilute tooj liab sulfate nrog dej nag lossis dej teeb roj teeb (koj tuaj yeem yuav nws hauv lub khw muag khoom hauv khw muag khoom). Ncuav cov tshuaj rau hauv dielectric iav lossis cov thawv yas, koj tuaj yeem siv lub tais yas tsis tu ncua. Txuas cov hlau mus rau ib qho ntug ntawm qhov khij khuam nrog ntawv sau los yog ntsia hlau thiab xaim txiv ntoo. Txuas lwm qhov kawg ntawm cov xov hlau mus rau roj teeb qhov xaus nrog tus cim "-".
Khi cov tooj liab ua ke tooj liab ua ke. Txuas cov xov hlau rau lub roj teeb zaum ob. Tag nrho cov ntsuas phom yuav tsum yog siab dua theem ntawm tsev ceem. Tig mus rau tam sim no thiab tos kom koj cov phaj yas los ua nrog ib txheej txawm ntawm liab tooj liab. Txoj kev no yog siv los ua metallize cov chaw nyuaj nrog cov cauj ntswj. Piv txwv, daim iav kav hlau txais xov rau lub xov tooj ntawm tes sib txuas lus tuaj yeem tsim nyob rau hauv txoj kev no.
