Txhawm rau nkag siab txog cov teeb meem coj los ntawm cov khoom siv me me rau kev luam ntawv luam tawm, peb yuav tsum xub nkag siab txog thaj tsam ntawm stencil printing (Area Ratio).
Rau cov ntaub ntawv luam tawm ntawm cov ntaub qhwv me me, qhov me me ntawm lub ncoo thiab lub stencil qhib, qhov nyuaj dua nws yog rau cov tshuaj pleev xim rau kom cais tawm ntawm cov stencil qhov phab ntsa.Yuav daws tau cov nplaum luam ntawv ntawm cov ntaub me me, muaj cov hauv qab no cov kev daws teeb meem. rau siv:
- Txoj kev daws teeb meem tshaj plaws yog txo cov thickness ntawm cov hlau mesh thiab ua kom cov cheeb tsam ntawm qhov qhib.Raws li qhia hauv daim duab hauv qab no, tom qab siv cov hlau nyias nyias, cov ntaub qhwv ntawm cov khoom me me yog qhov zoo.Yog tias cov substrate tsim tsis muaj cov khoom loj loj, ces qhov no yog qhov yooj yim tshaj plaws thiab zoo tshaj plaws.Tab sis yog tias muaj cov khoom loj ntawm lub substrate, cov khoom loj yuav ua rau tsis zoo vim yog cov tin me me.Yog li yog tias nws yog qhov sib xyaw ua ke nrog cov khoom loj, peb xav tau lwm cov kev daws teeb meem hauv qab no.
- Siv cov cuab yeej tshiab steel mesh kom txo tau qhov yuav tsum tau ua rau qhov sib piv ntawm qhov qhib hauv stencil.
1) FG (Fine Grain) steel stencil
FG steel ntawv muaj ib hom niobium caij, uas tuaj yeem ua kom zoo dua cov nplej thiab txo qhov kub thiab txias ntawm cov hlau, thiab txhim kho lub zog.Lub qhov phab ntsa ntawm laser-txiav FG steel ntawv yog huv si thiab smoother tshaj li ntawm 304 steel ntawv zoo tib yam, uas yog ntau conducive rau demolding.Qhov qhib qhov sib piv ntawm cov hlau mesh ua los ntawm FG steel ntawv tuaj yeem qis dua 0.65.Piv nrog rau 304 steel mesh nrog tib qhov qhib piv, FG steel mesh tuaj yeem ua kom tuab me ntsis dua li 304 steel mesh, yog li txo qhov kev pheej hmoo ntawm cov tin tsawg dua rau cov khoom loj.
