The market explosion of TWS

What is the TWS Coin Battery?
The TWS headset is a true wireless Bluetooth headset. The main feature is that it has no physical wires and is easy to carry. The cordlessness has prompted TWS headsets to require rechargeable batteries, including a pair of headset batteries and a charging compartment battery, accounting for about 10% -20% of the total cost. It is a key component that affects various performances such as battery life.

After replacing the

1. Independently developed patented technology
2. High performance
3. Good security
4. Small size, durable and safe for TWS

The Advantages of Rechargeable Button Batteries
When a button battery such as Airpod Pro is rated at 93 milliwatts, we believe that it has reached its maximum capacity. However, with the development of new Bluetooth technology, TWS can certainly use longer-lasting batteries.

To keep prices low, button batteries will not be used in semi-wireless earbuds because lithium polymer batteries are cheaper and fit the dimensions of these earbuds.

Before reducing the receiving coil to a diameter equal to or less than 12mm, it can be installed in a coin cell. Moreover, the button battery has been wirelessly charged during the day, and it is not far away that the charging box becomes a wireless charger.

Maintenance Method of Constant Temperature and Humidity Electronic Test Chamber

Maintenance method of constant temperature and humidity electronic test chamber:
1.Before the test, be sure to check that the water level in the water tank is not too high or too low. If the water overflows the water tank or is too low, the wet ball test cloth will not absorb water properly, and the accuracy of the wet ball will be affected. The water level can be kept about six minutes full. The water level of the water tank can be adjusted to adjust the height of the water tank. You need to check and add water almost every two or three tests. You can see the water pipe in front to replenish the water. The machine will alarm and stop working when there is no water.
2.If the machine is operated below 0 ℃, avoid opening the door of the box as much as possible, because at low temperature, if the door is opened, frosting of the internal evaporator and other parts is likely to occur, especially the lower the temperature, the worse Must be opened, the door opening time should be minimized.
3.When the temperature test box has completed low-temperature operation, be sure to set the temperature to 60 ° C and perform the drying process for about half an hour, so as not to affect the measurement time or freezing phenomenon of the next working condition.
4.The radiator (condenser) of the freezer should be regularly maintained and kept clean.
5.The humidifier barrel's water inlet pipe must completely exhaust the remaining air to prevent water from entering. After the machine finishes running at low temperature, it is necessary to set the normal temperature condition (30 ± 5 ℃) so that the temperature in the box will be normal temperature when the machine is stopped, so as not to affect the freezing phenomenon caused by the low temperature in the box and the fogging of the window glass .
6.During operation, unless absolutely necessary, please do not open the door of the box, otherwise it may cause the following adverse consequences:
－High temperature and humidity rushing out of the box is very dangerous for the operator.
－The inside of the door is still hot, which is easy to cause injury.
- Hot air may trigger a fire alarm and cause incorrect action.
7.Please note that the automobile rain testing chamber must be grounded safely and securely to avoid static induction.
8.Avoid turning off and on the freezing unit within three minutes.
9.If a hot sample is placed in the box, please use an external power supply for the sample power control. Do not use the power supply of the machine directly.
10.Circuit breakers and temperature over-temperature protectors provide safety protection for the test products of this machine and the operator, so please check regularly.
11.The correct installation of wet ball gauze can only ensure the correct measurement of relative humidity.
12.Testing of explosive, flammable and highly corrosive substances is absolutely forbidden.
13.Please read the controller manual and related manuals before operating the constant temperature and humidity machine.

The basis of washing air separation magnetic separation machine

Cleanliness is sometimes a neglected part of the material handling industry. Although the "satisfactory" cleaning effect is good, the most common hydraulic method for washing is not perfect. Use sub-standard washing methods as much as possible, but usually the "permissible percentage of harmful substances" is still acceptable in the material.

The purpose of cleaning building aggregate is to make it meet specifications, whether this is the quality standard for that particular aggregate, or to make it useful in other applications. In addition to cleaning, aggregate manufacturers can also use cleaning equipment to handle:
sizing
Classify or separate
Remove clay and silt
Remove soft rock, shale, coal, roots, branches and other debris

The function of the washing air separation magnetic separation machine is not only used for washing, but many people have not effectively used the versatility of the equipment.

Problems with washing equipment are more related to source deposits
If part of the quality control involves getting the aggregate to the desired grade, then you will rely more on other processes such as screening, crushing and mixing. Even if you use any of these methods to achieve your target level, you still need to clean the materials to meet the cleanliness specifications.

The easiest way to determine the economic applicability of aggregates is to test the source. This is done before production begins, so you can grasp the equipment needed and how much time it will take to bring the material to specification. Certain materials may require more work than the same polymerization in other fields, but only testing in advance will tell you whether this is the case.

Specifications are getting stricter
Operations performed in mines or quarries in particular require more effective cleaning and sorting methods. The farther these operations enter their reserves, the easier they see to extract less material, which means that more sludge and clay need to be removed from the aggregate. Although washing may be sufficient to rinse some materials, other materials are needed to remove the clay. In particular, sand and gravel benefit from proper equipment, as household gravel and sand are usually treated before use.

It is recommended to conduct daily exercises to ensure that the equipment and the entire system are operating normally. When you only look at each device, it may be difficult to troubleshoot the problem. If you cannot do this every day, then at least once a week the cleaning of factory equipment is enough to let you understand the status and efficiency of the system.

Automatic Optical Inspection (AOI) System For PCB Manufacturing

The automated optical inspection (AOI) system performs a visual inspection of the printed circuit board during the manufacturing process, and uses a camera to perform a very fine scan of the printed circuit board to check for any defects or malfunctions. AOI is the integration of optical, mechanical, electronic control and software, which can replace the human eye.

In the real world, PCBs are getting smaller and more complex. Even relatively simple boards can be composed of thousands of welded components. Using AOI to monitor the quality of PCBs and correct them in the process flow is the key to success in today's competitive PCB production environment.

Parts information is automatically created after importing files.

System Requirements
AOI systems are commonly used in the production of various products, but are particularly important for monitoring defects on printed circuit boards and accurate measurement beyond the ability of manual inspectors. They are capable of detecting various surface characteristic defects such as nodules, scratches, stains, open circuits and thinning of welded joints. However, the development of the AOI system for PCB is different from the AOI general system. In order to provide more real co-planar inspection functions and volume inspection data, the AOI system needs to use different types of cards to connect to devices such as robots and CCD cameras.

Why choose Insun
Investing in AOI systems means less waste, lower production costs and the highest output. Insun server motherboard can not only provide the necessary power for AOI system, but also work in the temperature range of 0 ~ 40 ° C.

How to choose LED light power supply

Whether you are building your own LED luminaire or refurbishing existing luminaires, you need to find the right power supply for the LED. You will need a constant current LED driver or a constant voltage power supply to make your LED work properly. There are many different factors to consider when choosing a power supply for LED lighting.

Ensure control of LED current
Most LEDs require current limiting devices to prevent the LEDs from being overdriven. The constant-current driver or current-limiting resistor is used to regulate the current flowing to the LEDs, so that they can operate safely and maximize their service life. The electrical characteristics of the LED will change with increasing temperature. If the current is not adjusted, the LED will absorb too much current, which will eventually cause the LED lamp to malfunction. If you want to build your own LED luminaire or work with any of our component star LEDs, a constant current device is required in the system.

Constant voltage power supply
The constant voltage power supply can be used to power LED lights that already have resistors or constant current drivers in the system. These types of products usually require a constant DC voltage. Unless you are using battery power or happen to have a constant DC voltage sufficient to meet your lighting needs, you will need a power supply to convert the power supply to a safe DC voltage for lighting.

How to choose the right power supply?
Power
First, confirm the lamp power. If you want to use one power supply to turn off more than one lighting, you must add up the total power to find the total wattage used. By providing a 20% buffer for the total LED power calculated by yourself, ensure that there is a sufficiently large power supply.

Voltage and current
When constructing LED lamps or replacing bad power supplies, it is important to first confirm that the output voltage is compatible with the LED voltage. LED products with built-in current regulators usually specify the input voltage that should be used. Another common application is the use of high-power LEDs with constant current drivers, which require DC voltage input. In addition, please make sure that the selected power supply can handle the input power you have. The line voltage will vary according to your geographic location.

Dimmable LED power supply
If your LED is dimmable and you want to adjust its brightness, make sure to use a power supply with dimming function. The power supply specification should list whether the power supply is dimmable and the type of dimmer control used.

Temperature and weather
The important factor that cannot be ignored when choosing a power supply is the area and environment to be used. If the power supply is used within its temperature parameter range, the operating efficiency of the power supply is the highest. The power supply specifications should include a safe operating temperature range. Placing the power supply in a small enclosure without a ventilation system is usually a bad choice. In this way, even with the passage of time, even the minimum heat generated by the source will accumulate and eventually the power source will be cooked.
led-light-power-supply
Each LED light power supply will also have an IP rating. The IP rating consists of a two-digit code that indicates the solid size and liquid pressure that the power supply can resist. The first number refers to the amount of solids that the device can withstand, while the second number refers to the amount of liquid that the device can tolerate. As each number increases, the level of protection also increases. As the first number increases, the product will be protected by smaller and smaller objects, making it less susceptible to any entry and damage. With the increase of the second number, the product will be protected from only being protected from light rain to full immersion.

Size
When choosing a power supply for your LED project, it is important to know where to install or install it. If it is to be placed in the product to be manufactured, it must be small enough to fit the space provided. If it is outside the application, there should be a way to mount it. There are various power supplies with different sizes and shapes to meet your needs.

I hope this article will help you find the right power supply for your LED light. Please take some time and then choose the one that best suits your situation and has safety requirements from the surrounding area in order to set it for long-term use.
