OFweek smart home network news Recently, Cool official to the outside world to confirm the Cool school enrollment enrollment news, said that there is indeed the matter, but the cancellation does not involve the enrollment of all schools, the number of network dismissed about 300 people are inaccurate.
As for the reason for the cancellation of the contract, the official explanation given by Coolpad is that due to the adjustment of the Coolpad business, the focus of this year's business will be on overseas markets, and those who qualify for overseas market positions will be retained.
In a short period of time, it decided to change the focus of its business, and made every effort to expand overseas. Cool has nearly given up to capture the domestic market. 
Cool is currently in a poor condition
Cool's 2016 first-half results showed that its revenue for the first half of the year was HK$5,277 million, a 39.9% drop from the same period last year. During the reporting period, it recorded a profit loss of HK$2.053 billion, a decrease of 173% compared with the same period in 2015.
In the Q1 2017 Q1 report released by Coolpad, Q1 Cool's operating loss was approximately HK$460 million. It is expected that operating losses in the first half of 2017 will increase to HK$600 million to RMB100 million; this compares with the same period last year. The loss was HK$162.8 million and there was a significant decline in operating performance.
The reason that Coolpad said its performance decline comes from the fierce competition of domestic mobile phone brands. The smart phone market is undergoing a shuffle, washing away Apple, Samsung, and the once-used "China Cool". As a result, Coolpad decided to enter the overseas market and shift its business focus.
Wouldn’t it be better to go overseas for Cool?
"Do you think that what you think is what you think?" It is fitting to use this sentence to evaluate the idea that Cool is trying to fight overseas.
The domestic market has been severely divided by the four major brands and it is almost empty. Although Cool is ranked ninth, the percentage is extremely low, and it looks like it will drop out of the top ten. In this case, giving up the domestic market is also reasonable, but the days of overseas travel to Cool seem to be no better.
According to a report released by IDC, a third-party statistical agency, the total smartphone sales in 2016 exceeded 1.47 billion. The top five mobile phone manufacturers in the total sales volume are Samsung, Apple, Huawei, OPPO and vivo. Among them, Huawei, OPPO and vivo accounted for 18% of the total in the international market.
In India, which has the most potential for growth in the Internet industry, Samsung, Xiaomi, OPPO, Vivo and Lenovo ranked the top five in their smartphone market share.
Of which millet shipped nearly 4 million, accounting for 14%. Compared with these brands, Cool is only now focusing on overseas markets and is already a latecomer. Cool has still not been able to avoid competition with the four major brands, in addition, Cool also have to face such a strong opponent as Apple, Samsung.
Cool is being dragged by music
From the previous cooperation to now being fully controlled by LeTV, Coolpad did not get any resources that are conducive to its own development. The collapse of the Letv ecosystem has caused Cool to be in a dilemma.
In November last year, after the outbreak of the financial crisis, LeTV was forced by its implicated share price, which fell to a low of HK$0.66 per share. In the month, Coolpad issued a profit warning, saying that it expects to record a loss of about HK$3 billion in 2016.
This is also the reason why Liu Jiangfeng said this at the press conference in March: Coolpad and LeTV are two companies. They don’t understand the operation of LeTV. LeTV’s funding situation has no effect on Coolpad. Cool does not want to be tired of music, can only choose to make their own way.
Wang Yanhui, secretary-general of the mobile phone alliance, once said that some current poorly-performing mobile phone manufacturers need to clarify their own market positioning and gain a firm foothold. "At least it is to live first, then adjust and then attack." Wang Yanhui said.
What is PCB box build?
After Quick Turn PCB production is completed, how to assemble various Electronic Components and Electronic Connectors on the PCB into a useful PCBA?
1. Mounted installation form
The mounting form of the surface mount type is to install the Electronic Components close to the surface of the printed board, and the gap between the Electronic Components and the PCB is about 1mm. The mounting lead of the board is short, the stability is good, and the insertion is simple. But it is not conducive to heat dissipation and is not suitable for the installation of high-heating components. The double-sided soldered circuit board has wires on both sides. If the Electronic Components is a metal shell and there are printed wires under the Electronic Components, in order to avoid short circuits, the shell of the Electronic Components should be padded with insulating gaskets or sleeves.

2. Suspended installation form
Electronic Components that are afraid of heat generally use the suspended installation method. The suspended installation form is to install the Electronic Components shell at a certain distance from the printed board surface, and the installation gap is about 3~8mm. To keep the height of Electronic Components consistent. Can be sleeved on the lead wire.

3. Vertical installation
In the high-density installation area of the printed circuit board, the vertical installation mode can be used for installation. The vertical installation mode is to install the Electronic Components shell with the axial bidirectional lead vertically. Electronic Components with large mass and thin leads should not use this form. During vertical installation, a large amount of heat is transferred to the short lead pin soldering. In order to avoid high temperature damage to the Electronic Components, a gasket or the like can be used to block the conduction of heat insulation.
The embedded installation form is to embed part of the Electronic Components shell into the embedded hole of the printed circuit board. Some Electronic Components that require shock protection can use this method to enhance the shock resistance of Electronic Components and reduce the installation height.
The form of mounting and fixing bracket is to fix the Electronic Components on the custom pcb fabrication with a fixing bracket. Some electronic components with heavier weights, such as small relay transformer chokes, etc., are installed in this way, which can enhance the firmness of the components on the circuit board.
When the installation height is limited in the bending installation form, the lead of the Electronic Components can be inserted vertically into the socket of the circuit board. The shell is then bent in the horizontal direction. The installation height can be appropriately reduced. For some electronic components with larger mass, in order to prevent the components from skewed leads from being broken due to excessive force, the same measures should be used for binding and gluing after bending to enhance the stability of the electronic components.
