1. Capacitor
Chip capacitors and other components in the package of 1206 and above should be used with cautions, there is a practical risk in the welding process.
Ceramic capacitors use NPO (C0G) and X7R two types which temperature coefficient control is better. Tantalum capacitors which rated voltage is lower than 25V are preferred. The forming voltage of the Aluminum Electrolytic capacitors should be 1.2 to 1.4 times of the rated voltage.

In general, the comparison of ESR values of various capacitor: aluminum capacitor > tantalum capacitor > ceramic capacitor;
The ripple current should not exceed the specifications under the high temperature, otherwise it will affect the service life; the limit value of each package is not recommended.

1.电容
慎用1206及以上封装的贴片电容等器件,焊接过程中有实效风险.
陶瓷电容选用NPO(C0G)和X7R这两类,温度系数控制较好。钽电解电容一般建议使用额定电压不超过25V产品。铝电解电容一般选取形成电压是额定电压的1.2到1.4倍。
一般情况下,各种电容ESR比较:铝电容>钽电容>陶瓷电容;注意高温下时的纹波电流不要超出使用规格,否则会影响使用寿命;每种封装的极限值不建议使用.


2. Diode & triode
When selecting the diode & triodes, pay attention to whether the following parameters are sufficient in the circuit to prevent the risk of damage.
Reverse breakdown voltage Vbr, reverse repeated operating voltage Vrwm, maximum average forward average current If, Instantaneous forward voltage Vf, reverse recovery time Trr, thermal resistance Rjc, maximum junction temperature Tjm.

2.二三极管
二三极管选型时注意以下参数在电路中是否够用,防止损坏风险。
反向击穿电压Vbr,反向重复工作电压Vrwm,最大平均正向平均电流If,正向压降Vf,反向恢复时间Trr,热阻Rjc,最高节温Tjm。

3. Crystals and crystal oscillators
Try to use the chip package. The largest shipment in the industry is 3.2mmx2.5mm (3225) package;
the AT cut fundamental frequency is selected, the preferred range is 12MHz~15MHz; a crystal oscillator generally only drives one device.

3.晶体和晶振
尽量选用贴片封装,行业内目前出货量最大的是3.2mmx2.5mm(3225) 封装;
选择AT切基频,优选范围12MHz~15MHz;一个晶振一般只驱动一个器件。

The year 2019 is the 37th anniversary of the CCTV Spring Festival Gala. Produced by China Central Television and broadcast on the eve of Chinese New Year, the gala is viewed nationally by extremely large audiences, which makes it one of the premier television events on China’s entertainment calendar.
2019年是央视春晚37周年纪念。春晚由中国中央电视台制作,在除夕夜播出,自然有非常多的观众收看,这使得它成为中国娱乐节目日程表上最重要的电视活动之一。

Each year, the directors of the gala try to adopt fresh ideas and introduce new faces. Some of them have become overnight stars, while some left with regrets.Let's find out more stories from behind the scenes.
每年,春晚的导演都在尝试采用新鲜的想法,引入新面孔。他们中的一些人一夜成名,而一些人则带着遗憾离开。让我们一起寻找更多的幕后故事。

With his handsome face and beautiful voice, Fei Xiang, a half Chinese, became the first Taiwan pop singer to cross the Strait and perform in the Spring Festival Gala.
有着帅气的脸蛋和漂亮的嗓音,有一半中国血统的费翔成为第一位跨过海峡,在春晚表演的台湾流行歌手。

With two songs that he performed at the Gala, “The Clouds of My Hometown” and “A Fire in Winter,” Fei Xiang became the most popular singer in the Chinese mainland over night. Most of us may not know that his success is owed to Deng Zaijun, the first female director of CCTV’s Spring Festival Gala.
由于在晚会上演唱了《故乡的云》和《冬天里的一把火》这两首歌,费翔一夜之间成为中国内地最受欢迎的歌手。我们中的大多数人可能不知道他的成功应该感谢邓在军,央视春晚的第一位女导演。

Deng Zaijun, director of 1987 Spring Festival Gala said, "I chose his song "A Fire in Winter" because the rhythm of the song was different. It was fashionable. But I was not sure if his dancing could be accepted."
1987年央视春晚导演邓在军表示:“我选择他这首《冬天里的一把火》是因为这首歌的节奏很不一样。它很时尚。但是我不敢肯定他的舞蹈能否被接受。”

But the response from the audiences proved that Deng made the right decision.
但是,观众的反应证明邓在军的决定是正确的。

In 1993, at its 10th anniversary, the Gala faced a lot of doubts including if it was necessary to hold the event every year. At that time, Zhang Ziyang rose to the challenge. The 37-year-old director produced many firsts, including the first usage of a big screen backdrop and the first adoption of second floor auditorium.
1993年,在春晚10周年的时候,晚会面临很多质疑,包括每年是否有必要举办这项活动。在那时,张子扬奋起接受挑战。这位37岁的导演创造了很多个“第一”,其中包括第一次使用大屏幕背景,第一次采用二楼观众席。

Zhang Ziyang said, "We made a three-sided stage. And some audiences were invited to the second floor. It was decorated like a tea house."
张子扬表示:“我们制作了一个三面舞台。一些观众被邀请到二楼。它被装饰得像个茶馆。”

Moreover, the 1993 Gala was noted for having live cross over between Hong Kong, Taiwan, and Macao.
此外,1993年春晚以港澳台的现场融合而闻名。

Zhang Ziyang said, "At that time, we had an idea, that is to hold a big gathering for Chinese everywhere. So we invited anchors in Taiwan, Hong Kong and Singapore. "
张子扬称:“那时候,我们有一个想法,那就是举办一次各地中国人的大聚会。所以我们邀请了台湾、香港和新加坡的主持人。”

Entering into the new century, the gala tended to be set on larger stages each time. The evolution of the Spring Festival Gala is, in many ways, representative of China’s technological growth, and social development.
进入新世纪,春晚每次都在更大舞台上举行。春晚的发展在许多方面代表了中国科技的发展和社会的发展。

Looking back at each year’s gala is just like looking at the past of Chinese people’s lives, and the trace of development of China. It involves hard work and exploration year after year. No matter how the gala evolves, for Chinese people, watching it has already become an indispensable ceremony on the eve of the New Year.
回顾每年的春晚就像是在看中国人过去的生活以及中国社会的发展轨迹。每年都需要辛苦工作和探索。无论春晚如何发展,对中国人而言,看春晚已经成为除夕一种必不可少的仪式。

A. Because the capacity of electrolytic capacitors is much larger than that of general fixed capacitors, the appropriate range should be selected for different capacities when measuring. In general, the capacitance between 1 ~ 47μF can be measured by R × 1k, and larger than 47μF can be measured by R × 100.
A、因為電解電容的容量較一般固定電容大得多,所以,測量時,應針對不同容量選用合適的量程。一般情況下,1~47μF間的電容,可用R×1k擋測量,大於47μF的電容可用R×100擋測量。

B. Connect the red meter to the negative pole and the black meter to the positive pole. At the moment of contacting, the pointer deflects to the right largely (for the same resistance, the larger the capacity, the larger the swing), and then gradually turn left until it stops at a certain point, which is  the forward leakage resistance that is slightly larger than the reverse leakage resistance. The leakage resistance should generally be above hundreds kΩ, otherwise, it will not work properly. In the test, if there is no charging phenomenon in the forward direction and the reverse direction, that is the needle does not move, which means that the capacity disappears or the internal circuit is broken. If the resistance measured is small or zero, it indicates that the capacitor is large leakage resistance or has been broken and damaged, cannot be use any more.
B、將萬用表紅表筆接負極,黑表筆接正極,在剛接觸的瞬間,萬用表指針即向右偏轉較大偏度(對於同一電阻擋,容量越大,擺幅越大),接着逐漸向左迴轉,直到停在某一位置。此時的阻值便是電解電容的正向漏電阻,此值略大於反向漏電阻。電解電容的漏電阻一般應在幾百kΩ以上,否則,將不能正常工作。在測試中,若正向、反向均無充電的現象,即錶針不動,則說明容量消失或內部斷路;如果所測阻值很小或為零,說明電容漏電大或已擊穿損壞,不能再使用。

C. For the electrolytic capacitor whose signs are unknown, it can be discriminated by using the above method. Frist, measure the leakage resistance at randomly and remember its swing. Then, exchange the test leads to measure a resistance. In two measurements, the large resistance is the forward connection, that is the black meter is connected to the positive pole and the red one is connected to the negative pole.
C、對於正、負極標誌不明的電解電容器,可利用上述測量漏電阻的方法加以判別。即先任意測一下漏電阻,記住其大小,然後交換表筆再測出一個阻值。兩次測量中阻值大的那一次便是正向接法,即黑表筆接的是正極,紅表筆接的是負極。

D. Via the multimeter to charge the electrolytic capacitor from the positive and the reverse side, the capacity can be estimated according to the magnitude of the swinging.
D、使用萬用表電阻擋,採用給電解電容進行正、反向充電的方法,根據指針向右擺動幅度的大小,可估測出電解電容的容量。
