The global semiconductor industry continues to deliver solid results, growing at more than 20 per cent a year for 13 consecutive months, despite double-digit annual growth in non-memory products in April due in part to strong growth in the memory market.

According to the semiconductor industry association (SIA), global semiconductor sales in April 2018 totaled $37.6 billion. April sales were up 1.4 per cent from the previous month. Sales are up 20.2% from a year ago.

So far this year, the global semiconductor industry has continued to deliver impressive results, with annual growth of more than 20 percent for 13 consecutive months, according to SIA President and CEO John Neuffer. Despite strong growth in the storage market, non-memory products posted double-digit annual growth in April, and all major regional markets saw double-digit annual growth. Semiconductor growth will be substantial this year and slow next year.

In April, sales in the Americas rose 34.1 percent, China 22.1 percent, Europe 21.4 percent, Japan 14.6 percent and Asia Pacific/other regions 10.2 percent, compared with the same period last year. China grew 3.2 per cent, Japan 2.7 per cent, Europe 1.4 per cent and the Americas 0.8 per cent. In Asia/elsewhere, however, the monthly decline was 0.8 per cent.

SIA endorses the global semiconductor sales outlook published by the world semiconductor trade statistics association (WSTS). The global semiconductor market is forecast to grow 12.4 percent to $463.4 billion this year, an all-time high, the WSTS said. But growth will fall to 4.4% next year.

Hope this greeting find you well. ~!~

Are you making a resolution for 2018? Warning: More than half of all resolutions fail, but this year, they don’t have to be yours. Here’s how to identify the right resolution to improve your life, create a plan on how to reach it, and become part of the small group of people that successfully achieve their goal.

Pick the Right Resolution

You’ll give yourself your best shot at success if you set a goal that’s doable — and meaningful too.

According to the time management firm FranklinCovey, one third of resolutioners don’t make it past the end of January.

A lot of these resolutions fail because they’re not the right resolutions. And a resolution may be wrong for one of three main reasons:

It’s a resolution created based on what someone else (or society) is telling you to change. 
It’s too vague.
You don’t have a realistic plan for achieving your resolution.

Your goals should be smart — and SMART. That’s an acronym coined in the journal Management Review in 1981 for specific, measurable, achievable, relevant and time-bound. It may work for management, but it can also work in setting your resolutions, too.

Specific. Your resolution should be absolutely clear. “Making a concrete goal is really important rather than just vaguely saying ‘I want to lose weight.’ You want to have a goal: How much weight do you want to lose and at what time interval?”. “Five pounds in the next two months — that’s going to be more effective.”

Measurable. This may seem obvious if your goal is a fitness or weight loss related one, but it’s also important if you’re trying to cut back on something, too. If, for example, you want to stop biting your nails, take pictures of your nails over time so you can track your progress in how those nails grow back out. Logging progress into a journal or making notes on your phone or in an app designed to help you track behaviors can reinforce the progress, no matter what your resolution may be.

Achievable. This doesn’t mean that you can’t have big stretch goals. But trying to take too big a step too fast can leave you frustrated, or affect other areas of your life to the point that your resolution takes over your life — and both you and your friends and family flail. So, for example, resolving to save enough money to retire in five years when you’re 30 years old is probably not realistic, but saving an extra $100 a month may be. (And if that’s easy, you can slide that number up to an extra $200, $300 or $400 a month).

Relevant. Is this a goal that really matters to you, and are you making it for the right reasons? “If you do it out of the sense of self-hate or remorse or a strong passion in that moment, it doesn’t usually last long.” “But if you build up a process where you’re thinking harder about what’s good for you, you’re changing the structure of your life, you’re bringing people into your life who will reinforce that resolution, then I think you have a fighting chance.” 

Time-bound. Like “achievable,” the timeline toward reaching your goal should be realistic, too. That means giving yourself enough time to do it with lots of smaller intermediate goals set up along the way. “Focus on these small wins so you can make gradual progress.” “If you’re building a habit, you’re planning for the next decade, not the next couple of months.”

The whole Kingtronics members feel much grateful for all customers' long-term support. Wish lasting prosperity and success.


Hereby we bring some news of adjustments on the production line, some parts will be discontinued since the raw marterial is hard to be purchased in the market, anyway repeat order can be negotiated case by case, we try best to continue supply.

Crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency. The most common type of piezoelectric resonator used is the quartz crystal, so oscillator circuits incorporating them became known as crystal oscillators.

Quartz crystals most are used for consumer devices, inside test and measurement equipment, such as wristwatches, clocks, radios, computers, cellphones, counters, signal generators, and oscilloscopes.
