Etching thev naus laus zis rau kev lim dej stainless

Firstly, Mesh loj ntawm lub lim txawv, thiab cov tuab ntawm cov khoom txiav txim siab ua kev tsim qauv thiab ua qhov yog ntawm cov roj stainless hlau. SenLoong muaj ntau cov khoom siv lim dej stainless hlau, nrog lim cov khoom siv thicknesses xws li {}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}

Etching txheej txheem Flow ntawm Stainless Hlau Lim:

 

1. Nto Nto Pretreatment

Kev ntxuav tu: Siv acetone thiab cawv rau ultrasonically huv stainless hlau ntawv ci thiab tshem roj.

Lub cev qhuav dej ziab: qhuav hauv 100 degree qhov cub rau 10 feeb kom tsis txhob muaj noo noo cuam tshuam rau tus photoresist.

2. Siv photoresist

Cov txheej txheej tsis zoo: tso cov photoresist mus rau saum npoo hlau, thiab tig lub tshuab txheej txheej ntawm {}} rpm los ua ib zaj duab xis unating.

PreLing ua ntej: ci ntawm 90-100 degree rau 1-2 feeb (kom tshem cov kuab tshuaj thiab txhim kho adhesion).

3. Raug thiab Kev Loj Hlob

Daim npog ntsej muag ua ntu zus: Tso cov qauv tsim qauv cov ntsej muag txawv lub ntsej muag kom nruj nreem tawm tsam saum npoo ntawm cov photoresist.

Tsim qauv: lub aperture thiab txuas yuav tsum xav txog qhov tom qab corrosion los ntawm etching, thiab lub aperture yog tsim tau feem ntau yog 10% loj dua lub hom phiaj.

Raug: Raug rau UV lub teeb rau 5-60} vib nas this, nyob ntawm qhov tuab ntawm cov nplaum thiab kev siv ntawm lub teeb ci.

Kev Loj Hlob: Soak hauv cov kev daws teeb meem, yaj cov ntu tsis muaj kev txwv, thiab ua rau cov hlau substrate.

4. Etching

Etching daws tej immerge: tso cov hlau tsim mus rau hauv cov tshuaj etching, xws li 40 degree 10-50 μ m / feeb.

Neutralization thiab kev tu: Tom qab etching, neutralize cov ntawv seem nrog naoh tov lossis dej huv.

5. De gluing thiab position-ua

Tshem tawm cov photoresist: Siv acetone lossis tshwj xeeb photoresist remover los tev tawm ntawm cov neeg photoresist.

POLISHING: Yog tias tsim nyog, electrolytic polishing yog siv los txo cov burrs ntawm lub qhov.

 

Raws li muaj nyob hauv daim duab hauv qab no, lub taub lim dej steel ua los ntawm cov txheej txheem etching tau tuab thiab hnav tsoos qhov zoo. Nyob rau tib lub sijhawm, nws tsis muaj kev cuam tshuam rau cov khoom ntawm cov khoom. Tsis muaj cua sov yog tsim thaum ua, thiab nws yuav tsis ua rau muaj kev tawm tsam lossis distortion ntawm lub lim screen. Lub aperture qhov raug tuaj yeem ncav cuag cov kev sib txawv nyob ntawm cov tuab ntawm cov khoom, thiab tam sim no tuaj yeem ua tiav tau ib qho yuam kev ntawm kev sib xws los yog {}}. 02mm.
