摘要
在易燃易爆的场所使用掌上电脑时,要求其具有防爆性能。介绍了一款掌上电脑,综合应用厚膜电子技术和本安防爆技术,研制了具有大功率、小体积的专用厚膜电阻,解决了掌上电脑的防爆难题,确保其在特殊场所的使用安全,极大地提高了工作效率。
PDA is required to be explosion-proof when it is used in easy exploding workplace. This paper introduces a type of PDA, which has comprehensively adopted thick application of electronic technology and explosion-proof technology. Specific thick film resistor with high-power and small size has been developed, and explosion-proof problem of PDA has been solved to ensure the safe use in special places.
