Ua ntej tshaj plaws, peb yuav tsum paub tias nyob rau hauv SMT ntau lawm kab, lubtsis siv neeg solder paste tshuab luam ntawvyuav tsum tau muaj siab precision, solder paste demoulding nyhuv yog zoo, cov txheej txheem luam ntawv yog ruaj khov, haum rau cov luam ntawv ntawm densely spaced Cheebtsam.Qhov tsis zoo yog qhov kev saib xyuas tus nqi siab thiab kev paub ntawm cov neeg ua haujlwm siab.
1. Thaum lub scraper ntawm lubSMT tshuab luam ntawvtxav mus rau pem hauv ntej ntawm ib qho kev ceev thiab lub kaum sab xis, nws yuav ua rau qee qhov siab ntawm cov tshuaj txhuam hniav, uas yuav thawb cov tshuaj txhuam hniav kom yob nyob rau hauv pem hauv ntej ntawm lub scraper thiab tsim lub siab xav tau los txhaj cov tshuaj txhuam rau hauv lub mesh lossis lub qhov dej;
2. Cov nplaum sib txhuam quab yuam ntawm solder paste ua rau shear ntawm solder paste ntawm qhov sib txuas ntawm scraper thiab net phaj ntawmSMT stencil tshuab luam ntawv.Lub zog shear txo cov viscosity ntawm solder paste, uas yog qhov tsim nyog rau kev txhaj tshuaj du ntawm cov tshuaj pleev xim rau hauv qhov qhib lossis xau ntawm cov qauv.Muaj qee qhov kev txwv kev sib raug zoo ntawm cov hniav ceev, hniav siab, hniav lub kaum sab xis nrog template, thiab muab tshuaj txhuam viscosity.Yog li ntawd, kev luam ntawv zoo ntawm solder paste tuaj yeem lav tsuas yog thaum cov kev txwv no raug tswj kom raug.
3. Thaum cov hniav txav mus rau pem hauv ntej nrog ib qho kev ceev thiab lub kaum sab xis, lub pob tw muab tshuaj txhuam tsim muaj qee qhov siab, txhawb nqa cov tshuaj txhuam hniav ua ntej lub scraper cov menyuam, yuav tsim cov tshuaj txhuam rau hauv mesh qhib (template) lub siab xav tau, solder paste viscosity kev sib txhuam los ua solder muab tshuaj txhuam nyob rau hauv lub scraper thiab daim ntawv hloov chaw shear qhib (template), shear quab yuam ua rau lub solder paste viscosity poob, yog li ntse rau hauv mesh;Thaum lub scraper tawm qhov qhib ntawm lub template, lub paste viscosity sai sai rov qab mus rau lub qub xeev.
Thaum peb ua hauj lwm, tsuas yog thaum lub solder paste dov nyob rau hauv pem hauv ntej ntawm lub scraper, muaj peev xwm tsim lub siab mus txhaj tshuaj solder paste rau hauv lub qhib;Tus nqi ntawm solder paste yog txiav txim siab los ntawm qib ntawm solder paste filling qhov qhib ntawm lub template, thiab kev ncaj ncees ntawm demoulding txiav txim siab solder paste leakage thiab kev ncaj ncees ntawm solder paste qauv.
