Industry highlights

Major semiconductor manufacturers announced that the price increase track continued to be high (Financial Associated Press)

According to media reports, semiconductor manufacturer Semtech recently issued a price increase letter, which will increase the price of all TVs (transient voltage suppression diode) new orders after March 14.

TVs, namely transient voltage suppressor, is a new type of high-efficiency circuit protection device widely used. It has extremely fast response time (sub nanosecond level) and quite high surge absorption capacity. It can be used to protect equipment or circuit from transient voltage generated during static and inductive load switching, as well as overvoltage generated by induced lightning. Ordinary TVs diodes are formed by a single PN node structure, with single structure and simple process. ESD protection devices have higher requirements for structural design and process, and the structure is more complex. They are generally designed as multi-channel PN junction integrated structure, which adopts multiple epitaxy, double-sided expansion junction or groove design. ESD protection devices can ensure the effective protection of miniaturized integrated circuit chips, which represents the technical level and development direction of TVs. TVs / ESD protection devices are widely used. Driven by 5g infrastructure and 5g mobile phones, electric vehicle charging piles, personal computers, industrial electronics and other markets, insiders expect TVs / ESD protection devices to increase significantly.

China’s decline in construction machinery narrowed in February, and there was a time lag in boosting demand for infrastructure (Financial Associated Press)

Cailian News Agency (Changsha, reporter Huang Lu) – the sales express data of “king of construction machinery” excavator came out in February this year. The sales volume of excavator in China continued to decline year-on-year. Although China’s monthly sales volume had negative growth for 11 consecutive months, the export sales volume maintained a high growth rate.

Industry machinery related people told the financial associated press that from the short-term monthly data, because the growth rate of Q1 last year was too good, the sales volume of this year must decline year-on-year and last year, but from the data of the past two months, it will be better than what was expected at the end of last year. The construction machinery industry has a certain periodicity, but the cycle is weakened. The judgment of the industry is low before this year and high after this year.

Risk tips

Macroeconomic fluctuation risk; Increased risk of trade conflict; Risks of raw material price rise exceeding expectations, etc.
