Improve strategy: Strengthen the degreasing and decontamination treatment. If it is ultrasonic cleaning, the degreasing function should be focused on and the effectiveness of the degreasing solution should be ensured; if it is hand wiped, consider first wiping with calcium carbonate powder and then wiping. Strengthen the baking before plating. If conditions permit, it is better that the substrate temperature can reach 300℃ or more, and the constant temperature should be more than 20 minutes to ... read more
There are two kinds of film color differences (not including stains). One is that the upper, middle, and lower film colors of the entire mask are inconsistent, that is, the spectroscopic test curves are different; the second is that the color of the single film is inconsistent. 1. The inconsistency of the upper, middle and lower film colors is called poor uniformity of the entire umbrella (cover), also called umbrella difference. The main reason is that there is a problem with the uniformity co... read more
Everyone knows that vacuum coating must be carried out in a vacuum environment. Therefore, if the vacuum coating machine has dust, it will affect the effect and quality of the vacuum coating. However, there is no way to ensure that the surface of the coating material is completely dust-free. Therefore, in order to minimize the surface of the material Under the premise of dust, the following points must be paid attention to when the vacuum coating machine is coating. (1) After the vacuum coating... read more
Vacuum coating machine mainly refers to a type of coating that needs to be carried out under a higher vacuum, including many types, including vacuum resistance heating evaporation, electron gun heating evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition, ion There are many kinds of beam sputtering. The main idea is divided into two kinds of evaporation and sputtering. Electric control cabinet operation1. Turn on the water pump and air source.2. Turn on ... read more
1. Vacuum chamber coating equipment mainly has two forms: continuous coating production line and single-chamber coating machine, stainless steel material manufacturing, argon arc welding, surface chemical polishing treatment, and various specifications of flange interfaces are welded on the vacuum chamber components. 2, vacuum acquisition part In vacuum technology, the vacuum acquisition part is an important part. The acquisition of vacuum cannot be achieved by a single vacuum equipment ... read more
