PCBA ishlov berishda ishlab chiqarish jarayonida ishlatiladigan antistatik uskunalarni inson elektrostatik himoyasi tizimi, statik polga qarshi-, anti-statik operatsion tizim va maxsus jihozlar sifatida tasniflash mumkin.
Insonning elektrostatik elektr taʼsiridan himoya qilish tizimiga antistatik bilaguzuklar, ish kiyimi poyabzallari, bosh kiyimlar, qoʻlqoplar va boshqalar kiradi. Bu umumiy himoya tizimi ham elektrostatik oqish, ham himoya qilish funksiyalariga ega va barcha statik elektr taʼminotini-odatda xarid qilish kerak. professional fabrikalar yoki do'konlar.
Direct contact with electrostatic sensitive devices should wear anti-static wristbands, wristbands should have good contact with human skin, wristbands must be no irritation to the human body, no allergic effects, wristband system to ground resistance value should be in the range of 106 108Ω.
Antistatik stol tagida kamida ikkita bilaguzuk ulagichi bo'lishi kerak, biri operator uchun, ikkinchisi texnik xodimlarni tekshirish yoki boshqa xodimlar uchun.
Antistatik ish joyiga-kiring yoki SSD xodimlari bilan aloqada-statik ish kiyimi kiyish kerak, antistatik ish kiyimlari mato GB12014- qoidalariga mos kelishi kerak- 2009 yil. Nisbiy namlik 50 foizdan yuqori bo'lgan muhitda antistatik ish kiyimlarini paxta mahsulotlarini tanlashga ruxsat beriladi.
Anti-static flooring is to effectively discharge human electrostatic through the ground to the earth as soon as possible, especially because of mobile operations and should not use wristbands of human electrostatic. At the same time, it can also discharge the static electricity on the equipment and work equipment. Ground anti-static performance parameters to determine both to ensure that in a relatively short period of time the electrostatic voltage down to below 100V, but also to ensure the safety of personnel, the system resistance should be controlled between 105 108Ω.
Antistatik pol qoplamalarida keng qo'llaniladigan materiallar-quyidagilar:
Anti{0}}statik kauchuk pol: oddiy konstruksiya, mukammal antistatik-ko‘rsatkich, lekin kiyinish oson.
PVX antistatik{0}}plastmassa pol: anti-statik ta'sir yaxshi, yuqori chidamlilik, keng qo'llaniladi.
Anti-statik gilam: antistatik ta'sir-yaxshi, ishlatish uchun qulay, lekin narxi yuqori.
Anti{0}}statik harakatlanuvchi pol: Yaxshi antistatik effekt-, chiroyli va juda yuqori narx.
Terrazzo zaminidan maxsus ishlov berish yo'li bilan foydalanishga ruxsat bering, masalan, tuproqli sim tarmog'ini oldindan yotqizish, karbürleme yoki antistatik vositani erga purkash va hokazo. yangi o'simliklar uchun.
Anti{0}}statik operatsion tizim ish yuzasi, ishlab chiqarish liniyasi korpusi, asboblar, qadoqlash qoplari, saqlash aravalari va tozalash suyuqliklari va hokazolarni anglatadi, bunda har bir jarayon ko'pincha komponentlar va tayyor komponentlar bilan aloqa qilish, ajratish yoki ishqalanish effektlariga ega bo'ladi. Yuqoridagi operatsion tizimlarda ishlatiladigan materiallar yuqori darajada izolyatsiya qiluvchi kauchuk, plastmassa, mato va yog'och bo'lganligi sababli, ular ishlab chiqarish jarayonida statik elektr energiyasini ishlab chiqarish juda oson, shuning uchun ularga anti-statik, ya'ni operatsion tizim bilan ishlov berish kerak. tizim anti-statik funktsiyaga ega bo'lishi kerak.
Antistatik operatsion tizimlar-o'z ichiga oladi:
Anti-static table mat. The operating table are equipped with anti-static mats, surface resistance between 105 109Ω, and through the 1MΩ resistance and ground connection, turnover boxes, boxes and all other containers should be made of anti-static materials, and labeled with signs.
Anti-static packaging bags. All plastic bags for packaging circuit boards or devices should be anti-static bags. Surface resistance of 105 109Ω, in the circuit board into or out of the bag, the hands should wear anti-static wristbands.
Anti-static logistics car. Used to transport devices, components of special logistics vehicles, should have anti-static function, especially the logistics vehicle rubber wheels, should use anti-static rubber wheels, the surface resistance of 105 109Ω.
Anti{0}}statik vositalar. Xususan, elektr lehimli temir, lehim tabancasi va hokazolar anti-statik funktsiyaga ega bo'lishi kerak, odatda elektr lehim dazmollari past kuchlanishda (24/36V) ishlashi kerak, lehimlash temir boshi yaxshi tuproqli bo'lishi kerak.
Muxtasar qilib aytganda, elektron plata yoki qurilma bilan aloqada bo'lgan barcha ob'ektlar, shu jumladan, bo'sh joyning yuqori-tezlikda harakatlanishi, antistatik-bo'lishi kerak. Ayniqsa, SMT yuqori{2}}tezlikda joylashtirish jarayoni, qurilmaning yuqori{3}}tezligi statik elektrning ko'tarilishiga olib keladi, elektrostatik sezgir qurilmalar ta'sir qiladi.
