The International Semiconductor Industry Association (SEMI) recently announced the mid-year overall equipment forecast report (annual equipment forecast), and it is estimated that the global original equipment supplier (OEM) semiconductor manufacturing equipment sales will decrease by 18.4% to US$52.7 billion in 2019. , lower than the historical high of $64.5 billion last year.

According to the SEMI report, Taiwan will seize the world's largest equipment market from South Korea, with the growth rate of 21.1% growth rate ranking first in the world, and North America growth of 8.4%; China will maintain second place for the second consecutive year. South Korea will fall to third place due to reduced capital expenditures.
Except for Taiwan and North America, overall spending in all regions this year will show a shrinking trend.
The report, published at SEMICON West 2019, predicts that equipment sales will resume growth in 2020, when it will jump 11.6% to $58.8 billion. The latest forecast also reflects that capital expenditures have been in a downward trend in recent days, and due to geopolitical tensions and other factors, market uncertainty continues to rise.
SEMI's mid-year overall equipment forecast report shows that sales of wafer processing equipment is expected to decline by 19.1% to $42.2 billion in 2019. Other front-end equipment, including fab equipment, wafer fabrication, and reticle/lens reticle equipment, is expected to decline 4.2% to $2.6 billion this year. Part of the packaging equipment in 2019 is expected to decrease by 22.6%. To $3.1 billion, semiconductor test equipment is also expected to decline 16.4% to $4.7 billion this year.
SEMI predicts that by 2020, the equipment market is expected to recover due to strong memory-related spending and new plants in mainland China. By then, Japan's equipment sales will surge 46.4% to reach 9 billion US dollars, and it is expected that China, South Korea and Taiwan will remain the top three markets next year, and mainland China will be the world's first champion. It is estimated that South Korea will become the second largest market with US$11.7 billion, and Taiwan is expected to reach US$11.5 billion in equipment sales. If the overall economic situation improves in 2020 and trade tensions subsidize, there is room for improvement in the above data.
The mid-year overall equipment forecast report is based on SEMI's industry-recognized World Fab Forecast database and information provided by equipment manufacturers. The overall equipment includes wafer processing, other front-end equipment, overall testing, and assembly and packaging equipment.
The following market size data is in US$1 billion:

Quartz  is the second most abundant mineral in the Earth's continental crust, after feldspar. It is made up of a continuous framework of SiO4 silicon–oxygen tetrahedra , with each oxygen being shared between two tetrahedra , giving an overall formula SiO2.

There are many different varieties of quartz, several of which are semi-precious gemstones. Especially in Europe and the Middle East, varieties of quartz have been since antiquity the most commonly used minerals in the making of jewelry and hardstone carvings.

Quartz can use in this luxury goods ,but also use in electrical products. If you can not believe , please visit our website . You will find our Quartz Crystal is very popular in the market right now!

Multilayer Ceramic Capacitor(MLCC) is an electronic part that temporarily stores an electrinical charge and the most prevalent type of capacitor today.New technologies have enabled the MLCC manufacturers to follow the trend dictated by smaller and smaller electronic devices such as Cellular telephone,Computers,DSC,DVC,GPS.

Besides chip mlcc capacitor, Kingtronics radial mlcc capacitor (mono capacitor) is unbeatable in the market - Good price, High quality and Short lead time.

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval.
