All existing elements have an idea that is considered as fundamental, and that allows the development and growth of these based on it.
Each science was created under a premise that surrounds a fundamental idea, and from there more and more functions and content related to it were developed, sharing the origin of everything. It also happens with the functions of certain machines, they are created under a basic principle and then specialize in certain things.
Visual inspection machines also have their fundamental principle: visualize one element and compare it with another.
A visual inspection machine is not exempt from this principle, so we can say that it has a fundamental idea, which is related (more than with observation), with the comparison of two elements to generate a response or result.
The vision inspection system manufacturers know that making the comparison work exactly, is what will make the visual inspection machine work and be reliable, that is why they put special attention in making the machine could observe every detail.
This is necessary since information is needed to classify all the elements present in the inspection.
In order for the visual inspection machine to determine which elements will pass the comparison and which not, it must have a kind of guidance, a focal point at which the vision inspection system manufacturers tell you what could be right and what should be discarded. For this, they have created a program that clearly shows the cases in which the object that is being studied should be discarded.
The system must include images of those previous tests that have been considered successful.
In order to be able to show the visual inspection machine the cases of ideal elements, it must be included in the system, visually and also through information of another class, which would be the elements to be classified and those that will pass the tests satisfactorily. Those elements that are included through images will serve as a guide to be able to compare all the others, as stated earlier this is the visual comparison.
A visual comparison takes place when placing an element next to another, observing them from different angles and being able to generate a kind of relationship between them. The characteristics to be compared must be viewed from different angles, first to make them coincide in their position and to be able to make the comparison in a better way, or it can also be achieved through the recreation of the images in a 3D format , superimposing one with the other and detailing the differences (considerable or not).
This is one of the reasons why vision inspection system manufacturers include a considerable amount of sensors and cameras in visual inspection machines, since they need to have a complete visual of the objects that leave the production lines, since some may be in a position and have a different meaning to the image included and classified as ideal. Being able to place at the correct angle, the visual comparison will start quickly.

What you need to know about 2D and 3D AOI systems (Automated Optical Inspection Systems)

Sipotek is a professional china automated optical inspection machine manufacturers located in shenzhen city,major products including visual inspection machine and automated optical inspection (AOI) machine.
As technological changes remain constant in the industry, it is important to understand the future capabilities of the AOI system and the flexibility of inspection tools. Will the system always be post-reflow? Are you going to seek to put the system in a new position on the line? What technologies are you building today and what is your future manufacturing road map?
Some AOI systems focus on a single task, i.e. Paste, Pre-reflow, Post-reflow or Post-wave. AOI’s most experienced suppliers will provide solutions covering all aspects of the manufacturing line in the same system, provide integrated 2D / 3D technologies and, at the same time, provide resources for the inspection of semiconductors and microelectronics.
AOI machine price is $120,000 for a good in-line unit and about $60,000 for a good bench-top unit.
The use of AOI is justifiable if you spend a lot of time to visually inspect your tables. The AOI machine is faster and more reliable than human element for the job. In addition, visual inspectors do not add quality to a product and are not generating revenue for the company. If the inspection is necessary (due to defects) and more than one person is dedicated to this operation, then the AOI is obvious. Then, you use only one person to inspect and give others something productive to do.
Correcting manufacturing problems should be based on concrete data. But difficult data is difficult to obtain from human beings. They pretend to see (and repair) what they, and. better understood or what is easy to justify. This effect can be eliminated with an AOI. If it is programmed correctly, you will be informed about the SPC and advise what to do. Most bench systems have their difficulties with the inspection of welding joints. But weld joints provide information about the printing process. This is considered to be a basic and necessary function.
After reflux, the AOI makes sense because it has the highest coverage of the defects. Problems such as raised pins, gravestone, open welding joints, some short and insufficient welding will not find before the oven. I would also not agree with the claim that AOI cannot do anything to prevent defects from occurring. The AOI can notify you in time to prevent the problem from occurring on the large number of plates – for example, warn in case of repeated defects found, so that you can correct the problem before it affects a large number of plates. Incorrect component, for example. You can also identify specific problems of fide or head P & P, if the connection to the P & P line is available. Using the SPC you can easily see your main problems and improve the agreement process. You can evaluate the capacity of your line for a certain process and so on.
Do not make the common mistake of focusing your evaluation on only one aspect of an AOI system. Megapixels alone are not important, programming times in a demonstration can deceive and not lose focus on your real need for AOI.
The coverage of defects, flexibility of the manufacturing strategy, use of measurement data, productivity, stability of the company, reliability of the system, programming and support times of ongoing programs, all need to be judged equally, in addition to the acquisition cost of a system.
The defects cover must always be the first reason to use any inspection platform. If you understand your manufacturing process and focus on the defects generated in your process, the AOI system will always provide maximum value and ROI, while increasing its overall quality.
To learn how a aoi system can automate the production process, one can visit the website https://www.sipotek.net/ .

Lithium Ion Battery Pack Technologies – Li-Ion and LiFePO4 Battery Pack Systems From China Manufacturers

Huizhou JB Battery Technology Limited is one of the leading custom lithium ion battery pack manufacturers from China, which is capable of designing and supplying portable power solutions to be used in electronic devices and other applications.
Today we will talking about lithium ion battery pack technologies – Li-Ion and LiFePO4 battery pack systems from china manufacturers.

A lithium-ion battery or Li-ion battery is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.
Lithium-ion batteries today are omnipresent today that they are invisible to us. Running in electronic devices, military equipment, military devices, emergency lighting systems, digital cameras, drones, bulbs, mechanical tools, inverters, ships, trains, airplanes, windmills and even in satellites. The basic science behind the battery is chemical energy converting to electrical energy containing three main components: Anode, Cathode, and Electrolyte. The revolution in the battery over the years are through several stages of chemical combinations and implementations. Starting from Voltaic Pile to Daniell Cell, then from Lead-Acid to Nickel Cadmium battery, further evolving to Alkaline Battery, Nickel-Metal Hydride (NiMH) and then finally to Lithium-ion battery. These are available in all shapes and sizes as per the need along with its possibly packed power capacity.
Working: The Lithium-ion battery pack consist of graphite, oxygen, metal, and of course lithium, which runs in a cycle of discharging and charging. While producing energy, the lithium moves back to the positive cathode across the electrolyte, and while charging, the ions move to the positive anode. This cycle repeats over the course of time and degrades the potency of the ions in providing the electric charge. The lithium-ion has 250Wh/kg (Watt-hours per kilogram) of energy while NiMH has mere 90Wh/kg. This is a vast difference for a small, portable and noiseless rechargeable battery.
Concern Parameters: The 10 parameters that a Lithium-ion battery pack’s development covers are high specific energy, specific power, affordable cost, longer life, better safety, wide temperature operating range, non-toxic, fast charging, lower self-discharge and longer shelf life. In the early stages, the cost of a Li-ion battery was $3000 per kWh, while Lead-acid battery cost $150 per kWh. But over the years, due to multiple benefits of Li-ion battery pack, being 150Wh/kg more than the NiMH, the cost is dramatically falling costing now $150 to $240 per kWh. Tesla’s goal is to reach $100 per kWh on lithium-ion battery packs for the cars.
NEW ERA: In 2005, there was a total of around $4900mil in the sales of lithium-ion batteries while in 2015 it is spiked to $15200mil wherein $4800mil is in automotive alone. It is expected to reach 10% on the total number of cars on the road to be battery EVs by 2020 from 0.3% today and to 35% by 2035. There is an even higher growth rate in China, Europe, and Japan when compared to the US. Statistically consuming 1900TWh for Li-ion battery pack by 2035, which is equivalent to power the whole of US for 160days.
FUTURE: There is still a lot to develop the battery technology as over the years we haven’t come up with anything further than lithium-ion battery packs configured in parallel or series to deliver the desired voltage, power density, and capacity. We sure have changed the contents and the proportion of the combination of raw materials to enhance the capabilities, but there is still a lot of work that has to be put into the battery technology. The targets are to reach over 700Wh/kg to that of 400Wh/kg we are on today. By 2020, 75% of batteries are expected to contain cobalt, in some capacity at least along with better anodes and enhancing electrolytes.
In the long run, custom lithium ion battery pack is to be cheaper and more efficient over to the existing ones. Moreover, Lithium Air technology is in cultivation, which shall have 10times the energy density than Li-ion. The world for lithium ion battery pack isn’t going to end for the next half century at least, making it the highest developing area in technology.

Advantages And Disadvantages Of The Lithium-Ion Battery From Custom Lithium Ion Battery Packs Suppliers Or Factory

Huizhou JB Battery Technology Limited is one of the leading custom lithium ion battery pack manufacturers from China, which is capable of designing and supplying portable power solutions to be used in electronic devices and other applications.
Today we will talking about advantages and disadvantages of the lithium-ion battery from custom lithium ion battery packs suppliers or factory.
The lithium-ion battery is one of the most popular choices for consumer and portable electronics. The high performance and fast recharge cycle also makes is a great choice for automobile, aerospace and military applications. Here are a few of the basic advantages of using the lithium-ion battery:
Compact size
The lithium-ion battery is smaller and lighter than most other types of rechargeable batteries in the market. The compact size makes is a popular choice for a wide range of electronic gadgets.
High-energy density
The high energy density of this type of battery makes it a very favorable choice compared to the alternatives. This means the battery has the ability to provide a lot of power without being large in size. The high energy is great for power-hungry gadgets like tablets, smartphones and laptops.
Low self-discharge
The lithium-ion battery has low self-discharge rate, which is estimated at about 1.5% per month. The slow rate of discharge means the battery has a long shelf life and the potential to be recharged and used a lot more often than other options. For instance, the metal-nickel hydride battery has a much faster self-discharge rate of about 20% per month.
Fast charge cycle
The fast charge cycle is a further reason for its great popularity in day-to-day electronics like phones and tables. The charge time is latterly a fraction of the alternative choices.
Long lifespan
The lithium-ion battery has the ability to complete hundreds of charge and discharge cycles. Over the battery’s lifespan, it is likely to see a reduction in capacity. For instance, after a total of 1000 cycles there is the risk of losing up to 30% of its capacity. However, the loss of capacity varies with the type and quality of the battery. The most advanced lithium-ion battery is more likely to hold full capacity until about  5000 charge-discharge cycles are complete.
Are there any disadvantages
In addition to the wide-ranging advantages of the lithium-ion battery, there are also a few disadvantages to note. A common issue is likely to relate to the cost. This type of battery is nearly 40% more expensive than its closest alternatives. A reason for the higher cost is the need to combine the battery with on-board computer circuitry to help control issues with current and voltage. Also, heat can be an issue. Any battery left or used in a high temperature environment will find the performance and quality of battery degrades faster.

An Overview Of Automated Optical Inspection(AOI) Machine From China Manufacturer Sipotek

Sipotek is a professional china automated optical inspection machine manufacturers located in shenzhen city,major products including visual inspection machine and automated optical inspection (AOI) machine.
Automation is defined as the process by which machines, equipment, systems or processes are steadily detected, judged, processed, analyzed, and controlled to accomplish a desired objective without direct involvement one or more persons , according to the needs of the man.
Automatic Optical Inspection (AOI) is an automated visual inspection of the manufacture of printed circuit boards (or transistors, LCDs) in which a camera independently scans the device being tested for catastrophic failures (for example, missing components) and quality defects (i.e. shape, inclined component, etc.). It is used commonly in the production process as it is a contactless test method. At several stages, it is implemented throughout the production process, including bare-edge inspection, welding glue inspection (SPI), post-reflow and pre-reflow phases, and other stages as well
Historically, the main place of AOI systems was after soldering or remolding “post-production”. Especially because AOI systems – post-reflow, can inspect most types of defects (component placement, missing solder, solder shorts, etc.) at a single point in the chain with a single system. In this way, the defective cards are reprocessed and the other cards are sent to the next step of the process.
Automated or automatic optical inspection (AOI) is a vital technique used in the manufacturing and testing of electronic printed circuit boards. Automatic optical inspections, AOI enables accurate and fast assessment of electronic components, especially printed circuit boards, to make sure that the quality of the product coming out of the production line is high and that the items are properly built and without any manufacturing defects.
The Need for automatic optical inspection, AOI
In spite of the significant improvements, modern circuits are much more complicated than those of a few years ago. The innovation of surface mount technology and subsequent size reductions make the panels particularly compact. Even relatively average circuit boards have thousands of welded joints, and that’s where most of the problems lie.
This increased complexity of circuit boards also implies that manual inspection is not a potent option nowadays. Even when this approach was accepted, it was understood that it was not particularly effective, the inspectors easily become tired and the bad construction not easily detected. Now that the market demands that high-volume, high-quality products come on the market very quickly, very reliable and timely methods are needed to ensure that product quality remains high. AOI, the Automatic Optical Inspection is a major tool in an integrated electronic testing strategy which ensures costs are kept at their lowest by detecting defects early in the production chain.
One solution is to use automatic or automated optical control systems. Automated optical inspection systems can be inserted into the production line immediately after the welding process. This way, they can be used to identify problems early in the production process. This has many advantages. With failures that cost more to adjust further in the production process, these are obviously the ideal place to look for defects.
In addition, process problems in the welding and assembly area can be detected from the early stages of the production process and the information used to quickly send feedback to previous phases. This way, a quick response can make sure that problems are quickly recognized and corrected before too many circuit boards are built with the same problem.
