Music payment audition users do not want to pay

In 2013, each site launched a music payment audition

Netizens say NO about payment

Users do not want to pay for the payment

There are hundreds of thousands of independent musicians on the "Music" section of Douban.com.com. In addition, the audition segment "Watercress FM" launched in the previous two years is also very popular among netizens. Currently, the monthly payment model launched by the channel is priced at 10 yuan/month and 50 yuan/half year. The paid version has greatly improved the quality of radio music. In addition, commercial advertisements inserted in music playback are also removed, and the listening environment is more pure.

After being billed by Douban Radio, the network explained in a statement: “We have always hoped to bring you a perfect listening experience, but the costs of copyright and bandwidth have caused us to digest it through in-stream ads. , And there is no advertising, of course, is a more perfect experience, but it also means higher bandwidth costs and copyright expenses. Based on this, we launched the "Fox Doppler FM Pro".

In fact, the issue of online music payment has been discussed for a long time. At the end of last year, it was reported that Warner Music and other companies will join Baidu, Tencent, Cool I and other music sites to launch the online music payment downloading overall plan, and plans to fully implement before the third quarter of this year.

Whether it is a record company, a singer, or an online music platform company, mentioning “why music downloads cannot end the free age” will mention “not many people are willing to pay for online music”.

SINA.com is currently launching a poll on “Download music to charge. Would you like to do it?”. As of 2pm yesterday, 80% of netizens have chosen the option of “listening to free music”. The rest are 9.5. % of the candidates selected "monthly downloads, 20 yuan per month (hypothetical), 5.3% of netizens selected "downloaded by track, a song a dollar. Many netizens said: "I have already paid for the Internet, and I should not give money to listen to songs. The spirit of the Internet should have been free. "It can be seen that there is no strong mass base for future attempts to pay for downloads.

Music websites have been losing money

At present, QQ music, Baidu music, cool dog music, etc. have all closed the free download channels for high-quality music. Taking QQ Music as an example, users can download music of general sound quality for free, and music with a sound quality code rate of more than 320K will require registered members and be paid to download. QQ "Green Diamond" users can not only download music after payment, but also enjoy many other value-added services, such as discounts on tickets purchased for concerts. The shrimp net is simply to download music download fees, each for 8 cents.

In addition to the above-mentioned websites, the most recent entry into the digital music field is Star Superstar, the largest physical record distribution company in China.

In January of this year, Starstar launched an online music mall. All record companies, music labels, and even individual musicians, as long as they hold copyrighted music works, can be sold on the site, and each song The pricing is determined by the copyright owner.

Since the launch of the music sharing platform on the Internet in 2002, music has become a free lunch. According to a survey conducted by the China Audiovisual Association's Recording Working Committee (hereinafter referred to as the Singing Working Committee), there are currently 400 million online music users in the Mainland, and the total music copyright market is estimated to exceed RMB 40 billion, but it can only receive 800 million yuan. .

In the second half of last year, the record industry began to set off a "proposed wave of charges." In November last year, the Recording Industry Commission established a subordinate digital music development working group to promote the establishment of an online music charging model, and unified charging time and charging mode.

However, at present, most music websites are still in a state of losing business. There is no unified model for distribution of income between music websites, record companies, and musicians. Taking shrimp rice net as an example, its split ratio with the record company is 1:1, and the income for downloading each song is 0.8 yuan, and the websites and record companies each have half.

In fact, prior to this, Shrimp.com paid 20 million copyright fees to the record company. Only when the download service had a revenue of more than 40 million, the record company would receive half of the proceeds. According to Wang Mi, CEO of Shrimp.com, in 2012, Shrimp.com's income from music download services was several million yuan. Therefore, after the removal of the 20 million yuan guarantee fee, paid downloads are still at a loss.

PCB SMT Stencil ,the unique goal  is to move solder paste to the bare Printed Circuit Board.

PCB Stencil , SMT Stencil, SMD Stencil , Laser Stencil , What is it?

Apart from all types of Printed Circuit Boards (PCBs) such as Prototype PCB , Aluminum PCB , HDI PCB , Flexible PCB , Rigid Flex PCB , Thick Copper PCB, High TG PCB , JHYPCB also manufactures solder paste stencils to meet Surface Mount Technology (SMT) requirements.

PCB Stencils, also called SMT stencils, SMD stencil, play a key role in transferring accurate amount of solder paste to correct positions on bare circuit boards ready for assembly. In other words, stencils can fast and efficiently ensure the most accurate solder paste amount and optimal electrical connection. With solder stencils, it is possible to use metal squeegee blades to apply solder paste easily over the openings on PCBs and make stencil to be well aligned with the surface of the advanced circuit board.

All of our SMT Stencils stencils are 100% laser-cut type 304 full-hard stainless steel, ensuring the finest quality finish on the market today. We use a .001" laser beam with 98% overlap creating an extremely smooth hole that provides the best paste release. Most stencil fabricators use a .003" laser leaving mouse bites on the aperture edge. You can choose a PCB Prototype stencil, a frameless foil stencil, or a rigid permanently mounted stencil. Both the frameless and framed stencils come in various sizes to accommodate your printer and stencil requirements.

PCB Stencil Types Available:

1. Laser-cut stencils

• Advantages: high accuracy; barely influenced by objective elements; trapezoid opening beneficial for demoulding; suitable for accurate cutting; reasonable price;

• Disadvantages: relative low manufacturing speed.

2. Chemical-etch stencil

The openings are etched into the metal using acid. Usually this kind of stencil offers better protection on material temper and hardness.

• Advantages: one-time formation; relatively high manufacturing speed; low cost;

• Disadvantages: tending to form sand clock shape or large openings; numerous manufacturing stages and accumulating errors; unsuitable for fine pitch stencils; bad for environmental protection.

3. Prototype PCB Stencil (Low-volume manual printing. Ideal for prototypes)

When prototyping dictates fast action with minimal cost, our prototype stencils are the best solution. Prototype Stencils gives you a quality stencil and framework so you can handle assembly from the convenience of your own desk.

Prototype SMT Stencil Features:

• Eliminate the registration difficulty associated in hand printing with a flat piece of metal
• Eliminate printer set up for short run prototypes
• Allow quick alignment for repeatability
• Save money over full size stencils designed for automated printers<
• Squeegee included

4. NEW Prototype PCB Stencil Kit (with leaded or lead/free solderpaste)

Includes Prototype Stencil, one board holder, leaded or lead-free solder paste (must specify), temperature marker, squeegee, ESK-safe gloves and alcohol wipe. 

5. NEW Pick and Place Tool

Handy and convenient for low quantity prototype assembly using the Prototype Stencils.  Re-usable, includes vacuum bulb and vacuum clips with diameters of 3/8", 1/4", and 1/8".

6. Framed SMT Stencils (Also called "Glue-in" or Mounted Stencils)

Framed stencils are laser-cut stencils designed for high volume screen-printing. With a framed stencil, your stencil is securely mounted to either a cast or extruded aluminum stencil frame a stencil frame using a mesh border, allowing for complete control.

Framed SMT Stencil Features:

7. Frameless SMT Stencil - Foil/Plate Only (for universal frames)

Foil or Plate Only stencils are designed to work within interchangeable plate or "universal" systems. Also referred to as "reusable", these stencils do not need to be permanently glued into a frame.

Frameless SMT Stencil Features:

8. Frameless SMT Stencil - Foil/Plate Only (for hand printing)

For times when you need precise control for smaller production runs, our Foil or Plate Only stencils are ideal. These frameless stencils allow you to hand print with precision just the amount you need and can be stored conveniently.

9. Electroformed SMT Stencils

Electroformed SMT stencils are nickel-based, electroform foils permanently mounted in a stencil frame using a mesh border to tightly stretch the stencil foil taut in the frame. Electroformed stencils offer the best paste release characteristics available and are frequently used for fine pitch (20 mil to 12 mil pitch) SMT applications on printed circuit boards. They are also used for µBGA's, Flip Chip, and Wafer Bumping (12 mil to 6 mil pitch).

Electroformed SMT Stencil Features:

• The smooth trapezoidal sidewalls of an electroformed stencil allow for better paste release
• Nickel has a lower coefficient of friction compared to stainless steel
• Electroform foils are harder than full hard stainless steel of comparable thickness, providing for longer stencil life
• 24-hour turnaround standard

Analysis and Treatment of Common Problems in PCB SMT stencil

How to Determine Stencil Size?

Stencil size is composed by two parts: internal size and overall size. Internal size is the size compatible with that of PCB ready to be assembled while overall size refers to the size compatible with printer parameter limit. As long as both sizes are accurately designed, stencil will be able to make full use of its functions.

Internal size of stencil can be figured out conforming to the following rule:

• Width of Framed Stencil = width of PCB + 100mm while its Length = length of PCB + 100mm
• Width of Frameless stencil = width of PCB + 200mm while its Length = length of PCB + 200mm

For example, if one circuit board size is 50*50mm, then the size of its framed stencil should be around 150*150mm and the size of its frameless stencil should be around 250*250 mm.

It's easy to remember and operate so it worked for manual solder paste printing in SMT assembly prior to the advent of automatic printer. It can be said that different PCB sizes lead to generations of different internal sizes of stencil.

When it comes to automatic solder paste printer, however, it's relatively solid. Overall size of stencil has to be determined by parameter limit of the equipment, that is, printer, because stencil has to work within the range of printer with a frame. Different printers feature different parameter regulations. As far as PCBCart is concerned, the stencil size compatible with our printer can be either 650mm*650mm or 736mm*736mm.

PCB designers have to focus on internal size of stencil, they don't need to care about its overall size since it is generally determined by the parameters of printer in your contract assembler workshop.
