"The SD-160 type ion sputtering apparatus is designed by means of the two stage (DC) DC sputtering principle. DC (DC) sputtering is the simplest, reliable and economical coating technology, and is the foundation of many manufacturers.
In addition to its usual basic structure, SD-160 is characterized by the configuration of a sample splash, a vacuum display table, a sputtering current indicator, a sputtering current adjustment controller, a miniature vacuum valve, and a timer. It is easy to control the vacuum chamber pressure, ionization current and choose the required ionization gas when working in conjunction with the internal automatic control circuit, so as to achieve the best coating effect. Specially designed bell ring rubber seal ring,
It is guaranteed that the long term use of glass clocks, which will not affect the vacuum of the sample sputter room, is "disintegrating"; the ceramic sealing high pressure head is more durable than the usual rubber seal. According to the ionization characteristics of the gas in the electric field, the large volume sample sputtering chamber and the corresponding area sputtering target are used to make the sputtering coating more uniform and clean.
In addition, SD-160 uses high stability, high sensitivity solenoid valve and dual gas automatic control system. It is easier to protect the sample and guarantee the quality of film forming. It is especially suitable for SEM sample preparation in electron microscope laboratory and electrode preparation for new material research.

需要鍍膜的樣品
| 電子束敏感的樣品 | 非導(dǎo)電的樣品 | 新材料 |
| 主要包括生物樣品，塑料樣品等。S EM中的電子束具有較高能量，在與樣品的相互作用過程中，它以熱的形式將部分能量傳遞給樣品。如果樣品是對(duì)電子束敏感的材料，那這種相互作用會(huì)破壞部分甚至整個(gè)樣品結(jié)構(gòu)。這種情況下，用一種非電子束敏感材料制備的表面鍍層就可以起到保護(hù)層的作用，防止此類損傷； | 由于樣品不導(dǎo)電，其表面帶有“電子陷阱”，這種表面上的電子積累被稱為“充電”。為了消除荷電效應(yīng)，可在樣品表面鍍一層金屬導(dǎo)電層，鍍層作為一個(gè)導(dǎo)電通道，將充電電子從材料表面轉(zhuǎn)移走，消除荷電效應(yīng)。在掃描電鏡成像時(shí)，濺射材料增加信噪比，從而獲得更好的成像質(zhì)量。 | 非導(dǎo)電材料實(shí)驗(yàn)電極制作觀察導(dǎo)電特性 |
