Anti-static kab xev hauv cov txheej txheem ntawm SMT tau txais
Antistatic kab xev yog tam sim no siv hauv SMT cov khoom siv thev naus laus zis. Nrog txoj kev loj hlob sai ntawm hluav taws xob tivthaiv kev tsim thev naus laus zis, tshwj xeeb tshaj yog kev lag luam me me ntawm cov khoom sib txuas thiab kev sib koom ua ke ntawm kev sib koom ua ke, CMOS cov cuab yeej siv 0.15-0.25mm cov txheej txheem tsim tau siv dav. siv. Nws cov hluav taws xob tawg feem ntau yog nruab nrab ntawm 50V thiab 100V, thiab nws muaj qhov sib koom ua ke ntau ntawm ultra-siab-ceev, high-zaus IC cov cuab yeej, uas yog rhiab ntau rau hluav taws xob zoo li qub. Qee cov khoom siv VMOS muaj qhov ntsuas hluav taws xob ntawm tsuas yog 30V, uas ua rau nruj stricter ESD kev tiv thaiv kev xav tau rau kev tsim cov txheej txheem ntawm cov khoom siv hluav taws xob saum toj no raug xaiv.
Hauv kev tsim cov khoom siv hluav taws xob, cov hluav taws xob hluav taws xob muaj peev xwm hloov tau cov yam ntxwv ntawm cov khoom siv hluav taws xob, ua rau muaj kev puas tsuaj lossis ua haujlwm tsis ruaj khov, ua rau muaj kev puas tsuaj rau cov khoom kawg lossis kev siv tsis raug. Cov kws tshaj lij tau ua cov txheeb cais, qhov khoom nruab nrab poob ntawm qhov hluav taws xob zoo li qub yog li 8-33%. Kev phom sij ntawm anti-static yog qhov zoo heev, yuav ua li cas tiv thaiv cov khoom siv hluav taws xob hauv cov txheej txheem ntau lawm? Cov kws tshaj lij ntseeg tias kev ua raws li hauv qab no yuav tsum tau ua:
1. Ntsuas av los tiv thaiv-qub;
2. Los tiv thaiv kev tiv thaiv zoo li qub ntawm chaw nres tsheb;
3. Qhov grounding tsis kam yog tsawg dua 4 ohms;
4, kub thiab av noo tswj: 20-30 ° C, tus txheeb ze cov av noo 30-70%;
5, ionizer, zoo thiab tsis zoo ion cua;
6, lub cev tiv thaiv zoo li qub;
7, lub pob ntim siv lub hnab ntim khoom los tiv thaiv zoo li qub, cov thawv ntim khoom zoo nkauj, lub thawv ntim khoom pov thawj thiab zoo li ntawd.
