關於真空鍍膜設備各人都相識幾多呢?本日小編著重就真空鍍膜設備的利用步調、合用範疇以及維護和調養要領等做以下先容,但願對小同伴們有用!
 
看點一
 
什麽是真空鍍膜設備?
 
 
真空鍍膜設備主要指一類需要在較高真空度下舉辦的鍍膜,詳細包羅許多種類,包羅真空離子蒸發,磁控濺射,MBE分子束外延,PLD激光濺射沉積等許多種。主要思路是分成蒸發和濺射兩種。
 
 
需要鍍膜的被成為基片,鍍的質料被成為靶材。 基片與靶材同在真空腔中。
 
 
蒸發鍍膜一般是加熱靶材使外貌組分以原子團或離子形式被蒸發出來,而且沉降在基片外貌,通過成膜進程(散點-島狀布局-迷走布局-層狀發展)形成薄膜。 對付濺射類鍍膜,可以簡樸領略為操作電子或高能激光轟擊靶材,並使外貌組分以原子團或離子形式被濺射出來,而且最終沉積在基片外貌,經驗成膜過蒸發鍍膜設備+所鍍產物圖蒸發鍍膜設備+所鍍產物圖程,最終形成薄膜。
真空鍍膜設備利用步調
 
 
1電控櫃的操縱
 
 
1)開水泵、氣源
 
 
2)開總電源
 
 
3)開維持泵、真空計電源,真空計檔位置V1位置,期待其值小於10後,再進入下一步操縱。約需5分鍾。
 
 
4)開機器泵、予抽,開渦輪分子泵電源、啟動,真空計開關換到V2位置,抽到小於2為止,約需20分鍾。
 
 
5)調查渦輪分子泵讀數達到250今後,關予抽,開前機和高閥繼承抽真空,抽真空達到必然水平後才氣開右邊的高真空表頭,調查真空度。真空達到2×10-3今後才氣開電子槍電源。
 
 
2DEF-6B電子槍電源櫃的操縱
 
 
1)打開總電源
 
 
2)同時開電子槍節製Ⅰ和電子槍節製Ⅱ電源:按電子槍節製Ⅰ電源、延時開關,延時、電源及掩護燈亮,三分鍾後延時及掩護燈滅,若後門未關好或水流繼電器有妨礙,掩護燈會常亮。
 
 
3)開高壓,高壓會到達10KV以上,調理束流可到200mA閣下,簾柵為20V/100mA,燈絲電流1.2A,偏轉電流在1~1.7之間擺動。
 
 
3關機順序

維護和調養要領
 
 
1、真空鍍膜設備每完成200個鍍膜措施以上,應潔淨事情室一次。
 
 
要領是:用燒堿(NaOH)飽和溶液重複擦洗真空室內壁,( 留意人體皮膚不行以直接打仗燒堿溶液,以免灼傷)目標是使鍍上去的膜料鋁(AL)與NaOH產生回響,回響後膜層脫落,並釋放出氫氣。再用清水清洗真空室和用布沾汽油清洗精抽閥內的汙垢。
 
 
2、當粗抽泵(滑閥泵,旋片泵)持續事情一個月(雨季減半),需改換新油。
 
 
要領是:擰開放油螺栓,放掉舊油,再將泵啟動數秒,使泵內的舊油完全排放出來。擰回放油螺栓,插手新油至額定量(油視鏡調查)。持續利用半年以上,換油時應將油蓋打開,用布擦清潔箱內汙垢。
 
 
3、擴散泵持續利用6個月以上,抽速明明變慢,或操縱失當,充入大氣,拆去聯絡水管,卸下電爐盤,將一級噴嘴擰出,AG亚游集团官方网站,先用汽油將泵腔及泵膽清洗一遍,再用洗衣粉兌水清洗一遍,然後用清水徹底清洗清潔,待水份揮發幹今後,裝好泵膽,插手新擴散泵油,並裝回機體,接好水管,裝好電爐盤,便可以從頭開機。在從頭開機前,要留意檢漏事情。要領是:啟動維持泵,關好大門,數分鍾後,調查擴散泵部門真空度是否到達6X10帕,不然要舉辦檢漏。查抄聯接處是否裝密封膠圈,或壓壞密封圈。解除漏氣隱患後方可加熱,不然擴散泵油會燒環,無法進入事情狀態。
How much do you know about vacuum coating equipment? Today xiaobian focuses on the use of vacuum coating equipment steps, scope of application and maintenance and maintenance methods to do the following introduction, I hope to partners useful!
 
 
 
What to watch for a
 
 
 
What is vacuum coating equipment?
 
 
 
 
 
Vacuum coating equipment mainly refers to a kind of coating equipment that needs to be prepared under a higher vacuum degree, including many kinds, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition, etc. The main idea is divided into evaporation and sputtering two.
 
 
 
 
 
Those that need coating are called substrates and those that need plating are called targets. The substrate is in a vacuum chamber with the target.
 
 
 
 
 
Evaporation coating is generally used to heat the target material so that the surface components are evaporated in the form of atomic groups or ions, and settle on the surface of the substrate to form a thin film through the film-forming process (scatter - island structure - vagal structure - lamellar growth). For sputtering coating, it can be simply understood that the target material is bombarded with electrons or high-energy laser, and the surface components are sputtered out in the form of atomic groups or ions. Finally, the surface is deposited on the substrate surface, which goes through the process of film-forming over-evaporation coating equipment + product diagram + product diagram, and finally forms a thin film.
 
Use steps of vacuum coating equipment
 
 
 
 
 
Operation of electric control cabinet
 
 
 
 
 
1) open water pump and air source
 
 
 
 
 
2) open the main power supply
 
 
 
 
 
3) start and maintain the pump, vacuum gauge power supply, and vacuum gauge file position V1. Wait for the value less than 10 before entering the next operation. It takes about five minutes.
 
 
 
 
 
4) turn on the mechanical pump and pump, turn on the power supply of the turbo molecular pump and start it. Switch the vacuum meter to the position of V2 and pump until it is less than 2, which takes about 20 minutes.
 
 
 
 
 
5) observe that after the reading of turbo molecular pump reaches 250, close the pump, open the front engine and the high valve to continue to vacuum, and only after the vacuum reaches a certain level can the high vacuum gauge on the right be opened to observe the vacuum degree. Only after the vacuum reaches 2×10-3 can the power of the electron gun be turned on.
 
 
 
 
 
Operation of 2def-6b electron gun power cabinet

2) at the same time open Ⅰ gun control and gun control Ⅱ power: according to the electron gun control Ⅰ power supply, delay switch, delay, power and to protect the light, three minutes after the time delay and protect the lights went out, if the back door is not closed or malfunction with the current relay, protect will normally on.
 
 
 
 
 
3) open the high voltage, the high voltage will reach over 10KV, adjust the beam flow to about 200mA, the curtain grid is 20V/100mA, the filament current is 1.2a, and the deflection current swings between 1 and 1.7.
 
 
 
 
 
3 shutdown sequence
