高溫老(lǎo)化房的老化原理(lǐ)有哪(nǎ)些?

發布時間:2018-12-19人氣(qì):290

高溫老化房的老化原理:高溫老化房是實行高(gāo)溫功(gōng)率應力(lì)試驗的一種設備,通過高溫老化房試驗來加速產品存(cún)在的缺陷的提早暴露。也就是給電子產(chǎn)品施加熱的、電的(de)、機械的或多(duō)種綜合的外部應力,模擬嚴(yán)酷工作(zuò)環(huán)境,消除加工應力和殘餘溶劑等物質,使潛伏故障提前出現,盡快使產品通過無效浴盆特性初(chū)期階段,進入恒(héng)定(dìng)期。
The aging principle of high temperature aging room: high temperature aging room is a kind of equipment to carry out high temperature power stress test, through high temperature aging room test to accelerate the early exposure of product defects. That is to say, applying thermal, electrical, mechanical or a variety of comprehensive external stresses to electronic products, simulating harsh working environment, eliminating processing stress and residual solvents and other substances, so that latent faults occur ahead of time, so that products can enter a constant period through the initial stage of invalid bathtub characteristics as soon as possible. 高溫老化房老化(huà)後實行電氣參數測量,篩選剔除無效或變值的元(yuán)器件,盡可能把產品的早(zǎo)期無效消(xiāo)滅在正常使用之前。這種為提高電(diàn)子產(chǎn)品可靠度和延長產品使(shǐ)用使用周期,對(duì)恒定性實行必要的考(kǎo)核,以便剔除那些有“ 早逝 ” 缺陷的(de)潛在 “ 個體 ” (元器件),確保整機優秀品質和期望使用周期(qī)的工藝就(jiù)是(shì)高(gāo)溫(wēn)老化房的原理。
After aging in high temperature aging room, electrical parameters are measured, invalid or variable components are screened out, and early invalidity of products is eliminated as far as possible before normal use. In order to improve the reliability of electronic products and prolong the service life of products, it is necessary to check the invariability so as to eliminate the potential "individuals" (components) with "premature death" defects and ensure the excellent quality of the whole machine and the expected service life of the process is the principle of high temperature aging room.

高溫老化房(fáng)內溫度升高(gāo)所需的熱量(liàng) 加熱器提供,加熱器采用不(bú)鏽鋼鎧裝結構,加熱器之間采用銅排連接,固定牢,外麵用鍍鋅(xīn)鐵網實行防護。
The heat heater needed for temperature rise in high temperature aging room is provided. The heater is made of stainless steel armoured structure. Copper bars are used to connect the heaters, which are fixed firmly, and galvanized iron mesh is used to protect the outside.
