HauvSMT solder paste tshuab luam ntawvluam ntawv PCB pawg thawj coj saib, ib qho ntawm cov txheej txheem yog siv cov squeegee los nyem cov tshuaj txhuam hniav, thiaj li hloov cov tshuaj txhuam los ntawm cov stencil mus rau PCB board. Squeegee system yog qhov nyuaj tshaj plaws txav mechanism ntawm lub tshuab luam ntawv, suav nrog squeegee kho mechanism, squeegee hloov chaw tswj thiab lwm yam.
I. Muaj nuj nqi ua los ntawm lub tshuab squeegee
Ua kom cov nplaum nplaum nthuav dav rau hauv ib txheej txheej thoob plaws tag nrho cheeb tsam stencil, lub squeegee nias lub stencil kom sib cuag ntawm stencil thiab PCB.
Lub squeegee thawb lub solder muab tshuaj txhuam rau ntawm stencil kom yob rau pem hauv ntej, thiab tib lub sijhawm ua rau cov tshuaj txhuam hniav ua rau lub stencil qhib.
Thaum lub template tawm ntawm PCB, nyob rau hauv lub PCB coj mus rau lub template graphics ntawm qhov tsim nyog thickness ntawm lub solder paste sab laug.
II. Scraper muaj hlau scraper thiab roj hmab scraper, thiab lwm yam, raws li, rau kev siv sib txawv.
Nws yuav tsum muaj kev sib txhuam siab thiab hnyav hnyav, thiab nws qhov hardness yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm solder paste printing. Sub riam ua los ntawm roj hmab, thaum lub squeegee lub taub hau siab loj heev los yog cov khoom yog mos, yooj yim rau embed lub hlau template qhov (tshwj xeeb tshaj yog cov qhov rais loj), thiab lub qhov nyob rau hauv lub solder paste extrusion, uas ua rau luam tawm cov duab. kev nyuaj siab, cov nyhuv luam ntawv tsis zoo. Vim li no, tib neeg siv hlau scraper es tsis txhob siv roj hmab riam. Hlau vice riam roob siab hardness alloy ua los ntawm heev qaug zog-resistant, hnav-resistant, khoov-resistant, thiab coated nrog ib tug lubricating zaj duab xis ntawm riam ntug. Thaum lub ntug ntawm cov hniav khiav ntawm lub template, lub solder muab tshuaj txhuam tau yooj yim thawb rau hauv lub qhov rais, tshem tawm cov solder kev nyuaj siab thiab siab thiab tsis tshua muaj undulation tshwm sim.
III. Nyob rau hauv xyoo tas los no tshiab kaw scraper tshuab tau tshwm sim.
Nws muaj cov txiaj ntsig hauv qab no tshaj qhov qhib squeegee tau piav qhia ua ntej.
1. Kev luam ntawv tseem ua tau nrog me me ntawm solder paste.
2. Nws yog qhov zoo rau solder paste thiab tiv thaiv oxidation ntawm solder paste.
3. Kev siv tau zoo ntawm cov tshuaj txhuam hniav.
4. Sab hauv siab tsub kom cov nyhuv filling ntawm solder paste thiab tiv thaiv qhov tshwm sim ntawm luam ntawv tsis xws luag.
5. Cov txheej txheem yooj yim dua thiab nrawm dua luam ntawv.
