LED燈條的製作流程是怎麼樣的?
LED生產流程是怎麼樣的
LED晶片製造製程是怎麼樣的?
其實外延片的生產流程非常複雜, 在外延片展會後, 開始LED外延片做下一個電極 (磷, 氮), 然後開始使用雷射切割LED外延片 (此前LED外延片主要採用鑽石切割刀), 製成晶片, 在晶圓的不同位置上提取九點測試參數.
- 主要測試電壓, 使晶圓的波長和亮度能夠滿足正常出貨標準參數，然後進行下一步操作. 如果九點測試不符合相關要求, 晶圓將被擱置以進行另一次處理.
2, 晶圓切割成晶片, % 視力檢查 (VI/VC), 操作者應使用放大顯微鏡 30 目視檢查次數.
3, 然後根據不同電壓使用自動分級機, 波長, 晶片亮度預測參數全自動選擇, 測試和分類. - 最後, 查看 (VC) 並給LED晶片貼上標籤. 晶片區域應位於藍膜的中心, 藍膜上最多有碎片, 但每片藍膜上的晶片數量不得少於晶片, 和晶片類型, 批號, 數量和光電測量統計數據記錄在蠟紙背面貼的標籤上. The chips on the blue film will undergo the final visual inspection according to the same standards as the first visual inspection to ensure that the chips are neatly arranged and of good quality. This makes LED chips (collectively known as squares on the market at present).
In the process of LED chip production, the chip with some defects or electrode wear, sorted out, these are the loose crystals behind, at this time in the blue film there are some do not meet the normal shipping requirements of the chip, it will naturally become a side piece or hair, etc.
Talked about in different locations on the wafer extraction parameters testing, nine points do to do not conform to the requirements of the wafer for additional processing, these cannot be directly used to make the LED wafer square piece, also won’t do any sorting, sold directly to customers, which is currently on the market the LED wafer (but also have good things in your wafer, such as the party).
LED霓虹燈
自從霓虹燈出現以來, after a hundred years of unfailing. It is a special low pressure cold cathode glow discharge electric light source, 與螢光燈等其他燈具不同, 高壓鈉燈, 金屬鹵化物燈, 汞燈, incandescent lamp and other arc lamp. Neon lights are produced by a cold cathode glow discharge under a high voltage field of inert gas filled in a glass tube. The color of the neon lamp is determined by the spectral characteristics of the inert gas. Fluorescent neon lights are filled with argon and mercury, 而霓虹燈發出藍色和黃色的光. These two types of neon lights are generated by excited radiation from the atoms of the working gas in the tube. Compared with other electric light sources, 霓虹燈具有以下特點:
第一的, 高效率
霓虹燈依賴兩端的電極發光，在高壓場中將管內的惰性氣體, 它不同於普通光源必須將鎢絲燒至高溫才能發光, 導致大量的電能以熱能的形式被消耗掉, 所以, 用同樣的電能, 霓虹燈的亮度較高.
二, 氣溫低, 使用不受氣候限制
霓虹燈因其冷陰極特性, 工作時管溫低於60℃, 因此可以放置在露天日曬雨淋或體內.
能耗低
在科技不斷創新的時代, the manufacturing technology of neon lights and the technical level of related parts are constantly improving. The application of new electrodes and electronic transformers has greatly reduced the power consumption of neon lights, 從 56 每米燈瓦數 12 每米燈瓦數.
四, 長壽
霓虹燈在持續通電的情況下連續工作, 壽命超過 10,000 小時, 這項優點是其他任何電光源難以達到的.
五, 柔性生產, 多種顏色
霓虹燈由玻璃管製成，可以燒製並彎曲成任何形狀，具有極大的靈活性. 透過選擇不同類型的管子並充入不同的惰性氣體, 霓虹燈可以產生多彩的, 多色光.
六, 動態的, 效果好, 經濟實用
霓虹燈螢幕由穩態光管和動態光掃描管組成, 可設定跳掃描, 漸進掃描, 混色變七色掃描. 掃描管由配備微電腦晶片編程掃描器控制, 掃描管按編好的程序亮或滅, 形成圖片流, 就像天空中的彩虹, 就像銀河系一樣, 更像是夢境世界, 迷人, 難忘. 所以, 霓虹燈是一種投資較少的廣告形式, 效果強、經濟實用
