Raws li cov txheej txheem, PCB stencil tuaj yeem faib ua cov hauv qab no:

1. Solder Muab tshuaj txhuam stencil: raws li lub npe qhia, nws yog siv los txhuam hamer muab tshuaj txhuam. Khib qhov hauv ib daim hlau uas sib haum rau cov ntaub ntawv ntawm PCB board. Tom qab ntawd siv cov ham muab tso rau hauv ncoo rau PCB pawg thawj coj los ntawm stencil. Thaum luam tawm ham muab tshuaj txhuam, siv cov cam muab rau saum stencil, thiab tom qab ntawd siv tus txhuam hniav rau hauv lub stencil Muab tshuaj txhuam SmD Cheebtsam, thiab tiv thaiv kev sib zog tuaj yeem ua txhua tus, thiab cov ntsaws sib xyaw ua ke yog kev siv ua ke.

2. Liab yas stencil: qhib tau qhib ntawm ob lub log ntawm cov khoom raws li qhov loj me thiab hom ntawm ib feem. Siv Dispensing (Dispensing yog siv cov kua nplaum compressed kom taw rau lub taub hau liab los ntawm cov kua nplaum liab rau tus pcb board los ntawm tus kheej mesh. Tom qab ntawd Mark cov khoom siv, thiab tom qab cov khoom siv tau txuas rau PCB, ntsaws rau hauv cov ntsaws ruaj ruaj thiab dhau nthwv dej ua ke.

3. Dual-txheej txheem stencil: Thaum tus lej pcb yuav tsum tau txhuam nrog cov hlua tshuaj txhuam thiab cov kua nplaum liab stencil xav tau siv. Lub dual-txheej txheem stencil yog muaj ntawm ob lub stencils, ib qho kev ua kom zoo li stencil thiab ib tus ruam stencil. Yuav ua li cas txiav txim siab seb yuav siv cov stencil lossis cov kua nplaum liab rau kev siv cov tshuaj txhuam? Ua ntej nkag siab tias puas txhuam tes muab tshuaj txhuam lossis cov kua nplaum liab ua ntej. Yog tias cov ham muab tshuaj pleev ua ntej, tom qab ntawd cov ham muab tshuaj txhuam stencil yog tsim rau hauv cov kua nplaum ua kom zoo nkauj, thiab cov kua nplaum liab stencil yog tsim rau hauv ib tug stepned stencil. Yog tias cov kua nplaum liab tau thov ua ntej, tom qab ntawd Red kua nplaum stencil yog tsim rau hauv ib tug zoo tib yam laser stencil, thiab lub cam stre stencil yog tsim rau hauv ib tug stephed stencil.
