Ua ntej sivDuab tau xaiv thiab muab tshuabkoj yuav tsum nkag siab cov haujlwm no:
1. Feem ntau hais lus, qhov kub tsis tu ncua ntawm SMT Rhiav yog 25 ± 3 ℃;
2. Cov khoom siv thiab cov khoom uas yuav tsum muaj rau cov ntawv luam ham ua lag luam: solder paste, steel phaj, scraper, ntawv so, cov ntawv plua plav, tus neeg tu lub cev, rab riam sib xyaw;
3.Qhov feem ntau siv cov tshuaj txhuam cov ntsiab lus sib xyaw ua ke yog Sn / Pb alloy, thiab cov alloy sib piv yog 63/37;
4.Cov khoom xyaw tseem ceeb hauv cov nplaum muab tshuaj tau muab faib ua ob qhov loj: tin hmoov thiab flux;
5. Lub luag haujlwm tseem ceeb ntawm flux hauv cov hlau txuas yog tshem tawm cov oxides, ua kom lub ntsej muag nro ntawm melting tin, thiab zam kom tsis txhob rov ua haujlwm;
6. Qhov ntim piv ntawm tin hmoov hais thiab Flux (Flux) nyob rau hauv ham muab tshuaj yog kwv yees li 1: 1, thiab feem tivthaiv yog li 9: 1;
7. cov ntsiab cai ntawm ham muab tshuaj yog thawj zaug, ua ntej tawm;
8.Thaum cov tshuaj txhuam cov cam yog siv rau hauv kev qhib, nws yuav tsum mus los ntawm ob qho txheej txheem tseem ceeb: kev ntsuas kub rov qab thiab sib tov;
9.Thaum txoj kev ua ntau lawm ntawm phaj steel yog: etching, laser, electroforming;
10.MOUNTING (LOSSIS TSO) TXUJ CI: SMT' s lub npe tag nrho yog Surface mount (lossis mounting) thev naus laus zis;
11.ESD sawv rau Electro zoo li qub paug, uas txhais tau tias electrostatic tawm hauv Suav;
12.Thaum ua qhov SMT ntaus ntawv khoom, qhov kev pab cuam suav nrog tsib ntu, uas yog PCB Cov Ntaub Ntawv; Khij cov ntaub ntawv; Cov ntaub ntawv pub rau noj; Cov Ntaub Ntawv Nozzle; Cov ntaub ntawv ib feem.
13.Qhov dawb ham Sn / Ag / Cu 96.5 / 3.0 / 0.5 melting taw tes yog 217 ℃.
14.The qhov kub thiab txias ntawm txheeb ze ntawm qhov chaw kom qhuav cub yog<>
15.Qhov feem ntau siv Cov Khoom Siv Passive muaj xws li: resistor, capacitor, inductor (lossis diode), thiab lwm yam. Cov Khoom Txuas Siv muaj xws li: transistors, ICs, thiab lwm yam.
16.Qhov feem ntau cov khoom siv ntawm SMT steel phaj yog stainless hlau rooj mount tshuab;
17.Qhov qhov tuab ntawm feem ntau siv SMT steel phaj yog 0.15mm (lossis 0.12mm);
18.Electrostatic them nres tawm tsam ntau yam kev tsis sib haum xeeb, ntsig txog, induction, electrostatic conduction, thiab lwm yam.;
Qhov cuam tshuam ntawm electrostatic them rau kev lag luam hluav taws xob yog: ESD tsis ua hauj lwm thiab electrostatic muaj kuab paug; Peb lub hauv paus ntawm kev tshem tawm cov electrostatic yog electrostatic neutralization, tiv thaiv av thiab thaiv.
