Thank you to Huanwei Electronics (Shanghai) Co., Ltd. for choosing the Shanghai Solon waterdrop angle measuring instrument

Thank you to Huanwei Electronics (Shanghai) Co., Ltd. for choosing the Shanghai Solon waterdrop angle measuring instrument.

Huanwei Electronics is an upgraded high-tech ODM company created by Sun Moon Group, a major packaging and testing company, two years ago (Huanwei Electronics' parent company is Huanxu Electronics, listed on the A-share market in Shanghai), mainly engaged in the research and production of wearable intelligent electronic products. Huanxu Electronics is located in Zhangjiang High tech Park, Shanghai, and Huanwei Electronics is located in Jinqiao Export Processing Zone, Shanghai, with more than 8000 employees. With Shanghai headquarters as the core business, it has formed five production bases in Shanghai, Shenzhen, Taiwan, China, Kunshan, Mexico, etc; As well as research and development bases in Shanghai, Taiwan, China, China, and procurement and outlets in Hong Kong, Japan, North America, etc. In 2005, 2006, and 2007, it was continuously awarded the title of "Shanghai Foreign Investment Double Excellent Enterprise"; In 2007 and 2008, it was continuously awarded the title of "Shanghai City"; In 2009, it was classified as an A * enterprise by the customs in Pudong New Area; In 2010, the output value of the parent company in Shanghai exceeded 8 billion yuan; The annual sales revenue of the company's merger exceeds 13 billion RMB; In 2012, the merged revenue of Huanxu Electronics was RMB 13.335 billion.

In the process of expanding the production line of Huanwei Electronics, Shanghai Solon has been used as its core partner for nearly 10 times, and the droplet angle measuring instrument has been applied to evaluate the surface cleanliness and plasma cleaning effect of circuit boards and chips, establishing a complete set of testing standards for the application of droplet angle measuring instruments.

As a provider of water droplet angle measuring instruments, Shanghai Solon also provides docking services to major plasma cleaning machine companies to achieve a win-win situation for all parties. We firmly oppose the use of ordinary and outdated digital protractors that fit circles and ellipses as evaluation criteria. We continuously improve our testing process and application methods to achieve standardization in testing and evaluating water droplet angle conditions. At the same time, it is also a service provided by end users and plasma cleaning machine manufacturers to achieve a repeatable and simplified water droplet angle measurement process.

The water droplet angle measuring instrument has been used for evaluating the plasma cleaning effect of chips, semiconductors, PCB boards, and LCD screens for many years. However, for many years, water droplet angle measuring instruments have used simple algorithms such as circle fitting and ellipse fitting to measure values, which clearly have significant shortcomings, including:

1. It is very difficult to confirm the volume accuracy of test droplets.

2. Is there a scientific basis for confirming the initial volume of the test droplet, such as 2uL?

3. Usually multiple droplets are needed to evaluate the effect, which is inefficient.

4. Unable to evaluate the situation of non axisymmetric droplets. How to solve the problem of material changes (resin, copper, gold plating) that may occur in the same drop of water, especially for various measuring points on PCB boards, semiconductors, or chips.

Therefore, in the past three years, the waterdrop angle measuring instrument has actually completed the stage of simple and low-cost digital protractors. In order to enhance the development of chips and wafers, as well as LCD and OLED screens in China, Shanghai Solon invented the Asha algorithm. Based on the fundamental principles of interface chemistry, gravity, surface tension, and contact angle are comprehensively analyzed to obtain the final water droplet angle value. This has made it possible for water droplet angle measuring instruments to achieve the improvement from pseudo contact angle measuring instruments to real water droplet angle measuring instruments, and ultimately solved the problems that have existed in water droplet angle measuring instruments

1. Automatic correction of gravity effect: As a result, the size of the droplet size will no longer affect the measurement results. This is an effect that cannot be achieved by circle fitting or ellipse fitting algorithms.

2. Automatically analyze the left and right angle changes in the same droplet, which can quickly determine whether there may be multiple materials present at the sample measurement point (if so, low droplet volume may need to be adjusted) and whether there is poor cleaning effect (a deviation of 5 degrees in angle value can be considered as poor material cleaning effect)

3. By spraying droplets with a diameter of 15um, the measurement of droplet angles at small positions can be achieved to improve analysis efficiency.

4. The micrometer level control accuracy of the real sample stage and lens ensures the rejection of errors in water droplet angle measurement.

5. The micrometer level ruby ball 3D contact angle calibration tool has achieved an adjustable contact angle measuring instrument.

Shanghai Solon will continue to cooperate with China's chip and semiconductor industries to enhance the measurement and analysis capabilities of our waterdrop angle measuring instruments, providing the strength we are capable of for the development of China's chip industry.
