SMT chip processing muaj ib qho tseem ceeb txhawb nqa cov ntaub ntawv, yog cov muab tshuaj txhuam.
solder paste muaj pes tsawg leeg mas muaj tin hmoov alloy particles thiab flux (flux muaj rosin, active agent, hnyav, thickener, thiab lwm yam), solder paste yog zoo li cov tshuaj txhuam hniav, siv rau solder paste tshuab luam ntawv solder paste nyob rau hauv pcb ncoo qhov chaw, kom lub Kev tso kawm tshuab mount nplaum hluav taws xob cov khoom siv, thiab tom qab ntawd kom rov ua dua cov kub kub kub yaj solder paste thiab tom qab ntawd kho cov khoom siv hluav taws xob rau hauv ncoo.
Solder paste vim li cas thiaj rov qab mus rau qhov kub thiab txias?
1. Vim li cas cov tshuaj nplaum yuav tsum tau sov so?
solder paste feem ntau muab cia rau hauv lub tub yees (5-10 degrees Celsius) ib puag ncig, los ntawm lub tub yees yuav raug coj tawm ntawm SMT Rhiav ib puag ncig qhov kub thiab txias tsis sib xws, yog ncaj qha qhib rau siv, los ntawm kev sib cuag kub tsis sib xws, qhov chaw ntawm cov tshuaj txhuam hniav. yuav ua raws li cov dej vapor, yog hais tias yuav reflow soldering siab kub, tej zaum yuav tshwm sim tawg tin, ua rau tsis zoo ntawm tin hlaws dai.Yog li ntawd, cov tshuaj nplaum uas tau muab tshem tawm ntawm lub tub yees feem ntau zoo dua kom rov qab mus rau qhov kub ntawm 2-4H.
2. Vim li cas thiaj yuav tsum tau muab tshuaj txhuam?
solder paste muab tso rau hauv lub tub yees, vim hais tias ntawm cov khoom sib txawv ntawm solder paste, muab tso rau ib tug ntev lub sij hawm, ntau yam khoom ntawm solder paste yuav tshwm sim txheej txheej, yog li koj yuav tsum tau do ( stirring nyob rau hauv tib txoj kev 20-30 lem. tuaj yeem ua tau), yog tias tsis nplawm ncaj qha nrog, tom qab ntawd ntau yam khoom siv ntawm cov tshuaj txhuam hniav tsis sib xyaw, tsis tuaj yeem ua si ntawm kev siv cov tshuaj txhuam hniav nws tus kheej.
Yog vim li cas vim li cas cov tshuaj txhuam hniav yuav tsum tau khaws cia hauv lub tub yees tsis yog ncaj qha rau ntawm qhov chaw yog tias cov tshuaj txhuam hniav muaj cov kuab tshuaj thiab cov rosin, uas yuav evaporate yog muab tso ncaj qha rau hauv ib puag ncig ib puag ncig, yog li ua rau huab cua qhuav.
Muaj tsis siv neeg solder paste tswj cov khoom nyob rau hauv kev ua lag luam, nrog rau kev cia, tempering thiab tsis siv neeg nplawm, thiab lwm yam. Yog tias lub tuam txhab loj thiab siv ntau cov tshuaj pleev xim rau, koj tuaj yeem yuav cov khoom siv los tswj thiab siv cov tshuaj txhuam hniav.

Standard Configuration
1. Qhov tseeb Optical Positioning System
Plaub txoj kev teeb pom kev zoo yog kho tau, lub teeb siv lub teeb yog adjustable, lub teeb yog ib yam, thiab cov duab nrhiav tau zoo dua.
2. High efficiency thiab siab adaptability stencil tu system
Mos hnav-resistant roj hmab so phaj, ntxuav txoj kev qhuav, ntub thiab nqus
kev tu kom huv, yooj yim disassembly.
3. Ntse squeegee system
Kev txawj ntse programmable teeb tsa, ob lub zog ncaj qha ncaj qha tsav squeegee, built-in precision siab tswj qhov system.
4. Tshwj xeeb PCB thickness adaptive system
Lub platform qhov siab tau txais kev ntsuas raws li PCB thickness teeb tsa, uas yog ntse, ceev, yooj yim thiab txhim khu kev qha hauv cov qauv.
5. Solder Paste Printing Kev soj ntsuam zoo
2D muaj nuj nqi tuaj yeem tshawb xyuas qhov teeb meem luam ntawv sai sai, cov ntsiab lus tshawb pom tuaj yeem nce ntxiv arbitrarily.
6. Printing Axis Servo Tsav
Txhim kho qib raug, muab kev tswj hwm kev luam ntawv zoo, kev ua haujlwm ruaj khov, txuas lub neej kev pab cuam.
