Mubikorwa byacu bya buri munsi no kubaza abakiriya, twasanze hari ibibazo byinshi bijyanye na anti - ibipimo ngenderwaho bya "anti - static silicone foam board" mubantu. Nigute "anti - static"? Nibihe bipimo byemewe byo kwipimisha? Nibihe bisabwa bitandukanye muburyo butandukanye bwo gusaba? Uyu munsi, reka tubisobanure neza.
Ibipimo ngenderwaho: Kurwanya ni urufunguzo
Igipimo cyibanze cyo gupima anti - imikorere ihamye ni ukurwanya. Ukurikije inzira inyuramo ikigezweho, twibanze cyane kubintu bibiri:
1.Ubuso bwa Surface (Ubuso bwa Resistivite): kurwanya ibintu iyo bigendagenda hejuru yubuso bwayo. Igice: Ohm (Ω)
2. Umubyigano wa Volume (volume Resistivity): kurwanya ibintu iyo bigezweho. Igice: Ohm · cm (Ω · cm).
Kubikoresho byoroshye nka rebero ya silicone ifunze, kwihanganira ingano mubisanzwe ni ikimenyetso cyingenzi kuko gishobora kwerekana byimazeyo amashanyarazi muri rusange.
2, Ibyingenzi Byibanze hamwe na Grade Itondekanya Kugeza ubu.
Nta bipimo bihuriweho rwose byerekana amanota yo kurwanya - ibikoresho bihagaze ku rwego mpuzamahanga. Nyamara, sisitemu nyamukuru nuburyo bukurikira byavuzwe cyane kandi byemewe:
1. Ibipimo by'ishyirahamwe rya ESD (ESDA). Igipimo cyacyo ANSI / ESD S20.20 ishyira ibikoresho mubyiciro bitatu, nibyingenzi kugirango dusobanukirwe icyiciro cya anti -:
1) Ibikoresho byayobora (Imyitwarire): kurwanya ubuso: munsi ya 1 x 10⁴ Ω (ni ukuvuga,<10,000 Ω) volume resistivity: Less than 1 x 10⁴ Ω·cm. Characteristics: The charge dissipates extremely fast, which may cause rapid discharge of electrostatic sensitive components (CDM damage). It is often used in situations where grounding is required and charges need to be discharged quickly, such as anti-static floors and table MATS.
) Irashobora gusohora ibintu bihagaze hasi kubigenzurwa kandi bitinda cyane, birinda kubyara imigezi minini ako kanya, bityo bikarinda umutekano mubice byinshi bya elegitoroniki.
3) Gukingura ibikoresho: Kurwanya ubuso: birenze cyangwa bingana na 1 x 10¹² Ω (ni ukuvuga, Birenze cyangwa bingana na 1.000.000.000.000 Ω) Kurwanya ingano: birenze cyangwa bingana na 1 x 10¹² Ω · cm Ibiranga: Amashanyarazi ntashobora gutemba kandi amashanyarazi ahamye arashobora kwegeranya. Rubber isanzwe ya silicone iri muriki cyiciro.
2. Ibindi bipimo bisanzwe
ASTM D257: Sosiyete y'Abanyamerika ishinzwe ibizamini n'ibikoresho, ubwo ni bwo buryo busanzwe bwo gupima gupima ubukana bwa none cyangwa imyitwarire y'ibikoresho.
IEC 61340: Igipimo mpuzamahanga cya komisiyo ishinzwe amashanyarazi, gisa na ESDA, nacyo ni gahunda yemewe ku isi yose yo kurinda amashanyarazi.
Ibipimo bya gisirikare nka MIL - PRF - 87893: Bafite ibisabwa bikomeye kandi byihariye kugirango bakore ibikoresho birwanya static.
Kurwanya anti - static kuri anti - static ya silicone ifuro ifatika ahanini biterwa nubunini bwayo / ubuso bwayo buba buri muri "static dissipation" iri hagati ya 10⁴ na 10¹¹ Ω · cm. Nibihe byihariye - urwego wahisemo biterwa na electrostatike sensibilité yibicuruzwa ushaka kurinda hamwe ninganda zinganda.
