              A common fault handling of reflow soldering is analysed


Reflow soldering heat alarm prompt temperature difference is too big or too small, in the process of computer tip ‘communication failure can’t start the machine, according to the two kind of phenomena, we had a lot of test and analysis work, draw the following conclusions:

1, in the process of reflow soldering heat suddenly alarm prompt “temperature range of a certain temperature too low or a certain temperature and set temperature difference is too large”.
Aiming at this phenomenon, we can preliminary judgment fault will occur in the heating or part overheating protection, and so will all overheat protection switch sub let its failure, and start the machine, found that seems to be normal.After further analysis, under the condition of the overheating protection switch sub machine can work, but in the event of heating, the temperature rise too high a less protection of defense, will bring more serious consequences.In order to solve this problem, we must put 16 from heating unit to find out one or several thermal protection switch failure, we will each heating unit with this problem apart, examine its overheating protection switch, found problems the second heating unit overheating protection switch, with a moving contact bimetallic strip fixed weak, cause the moving contact and the static contact point contact is not good, or not at all contact (normally two contacts should be contact together and conduction).Because there is no the second heating unit of the spare parts to replace we will switch sub to ensure production run smoothly.To this can solve the problem, but as soon as possible to the broken overheating protection switch is off, so as to achieve the purpose of protecting the second heating unit.

2, if the downtime is longer, when it turns switched on again reflow computer tip ‘communication failure and can’t start the machine for a long time to let the heat.
Aiming at this phenomenon, we preliminary suspect as the communication line fault, then replaced the telecommunication lines, the question remains, so denied this conjecture.After further observed, when the communication is not successful, the lights on the status of the controller is not normal, orange lights should be flashing, and should not go out.Based on manual measuring line 1001 and line voltage between 1007 found that the voltage is not constant for the + 5 VDC, about + 2 VDC when communication is not successful, the problem is out of here, why the voltage is too low, the original control panel in the end of the machine here are two simulated load resistance, resistance ought to be ‘5’R , but actual value only two ‘2’R, but I have measured the value to change it into ‘5’ R problem is resolved.

How to gang place in LED pcb assembly

For cost-saving or technical reasons (such as improved assembly), multiple circuit boards may be combined to form one large board, a “panel”. This panel is then produced just as a single large http://bestacnedrug.com circuit board. Consult with us to design the distance of LED chips is same as the spindle distance of placement head.

Why not Nozzle exchange for LED pick and place machine

1. As we consider that many customers products don’t have so many kinds of components in a board .

2. For example ,though in a board ,there are about 20 kinds of different components,but the size of many components are nearly . Sometimes just need about 3-4 kinds of nozzles is ok.

3. Besides, our S-EF30000 have 8 spindles, can install 8 kinds of different nozzles at a time,has mostly satisfied customers’ requirements of production , but also save machine’s cost for them .

4. As per your production ,if no need to install so many kinds of nozzles at a time and  change the nozzles automatically frequency , if we add a alternate pick up nozzle tray on our machine ,won’t it add your cost of the machine?

5. We won’t suggest you to buy our most expensive and with too many functions machine to increase your cost if your production no need.

Vision System application for LED pick and place machine

1)Visual registration system 

(2) Laser detection registration system .

Both have different characteristics, so there are differences in the use.

Comparison:

Laser detection registration system:

Laser counterpoint to allow flight correction, capable of handling all shapes and sizes of components, and can accurately determine element position and direction, but, even more complex laser systems cannot measure the pin and pin spacing.

Visual registration system :

The visual system is able to judge the position and orientation of components and can  measure http://trueviagraonline.com lead and lead spacing at the same time .In addition, the visual system does not need to adjust the system will be able to adapt to the update components encapsulation, thus has better flexibility.

$50000 SMT Line for LED Products Assembling

 

 

This line is designed specially for beginning manufacturers of LED lighting systems.

Special nature of LED systems production is the necessity to have high speed equipment for various LEDs and minimal set of SMD components.

The line is based on architecture of a standard line for SMD component assembly, but the equipment is modified specially for work with LEDs.

 

The oven length allows working with long aluminum PCBs (with high heat capacity) according to temperature profile recommended by LED vendor, without decreasing of operation time for the rest of the line.

Special vacuum nozzles are used for placing LEDs on PCBs; they are designed to avoid damage of their silicone lens. These nozzles are made of non-adhesive materials to avoid sticking of lens.

The unique ability of the line is work with LEDs in bulk; that could lower the cost of purchased components as well as the final cost of the product.

Zuckerberg Responds To Critics, Explains How He’s Spending $45B

Zuckerberg Responds To Critics, Explains How He’s Spending $45B


 by Katie Roof 

On Tuesday, Facebook co-founder and CEO Mark Zuckerberg posted a powerful announcement — not only did he reveal the birth of his daughter, Max, but he shared plans to give up 99% of his personal Facebook shares over the course of his lifetime and use them to fund projects and causes through a newly formed entity called Chan Zuckerberg LLC.

The announcement generated a lot of attention, much of it due to the sheer volume of Zuckerberg’s net worth — $45 billion! While many people, including Bill Gates and Michael Bloomberg, praised him for his generosity, others expressed confusion and even questioned his motives for giving his money away.

Looking to alleviate some of those concerns, in a post Thursday,  Zuckerberg further explained how he and his wife Priscilla Chan, plan to delineate their funds.

“Our initial focus areas are personalized learning, curing disease, connecting people and building strong communities. We’ve already made many investments over the past five years in these areas — education, science, health, internet access and inclusion — and you can see a summary of our investments on the Chan Zuckerberg Initiative page timeline.”

Zuckerberg further addressed the allegations that this organization was a way to avoid taxes, and explained that by structuring the Chan Zuckerberg entity as an LLC, that their shares will still be taxed.

“By using an LLC instead of a traditional foundation, we receive no tax benefit from transferring our shares to the Chan Zuckerberg Initiative, but we gain flexibility to execute our mission more effectively. In fact, if we transferred our shares to a traditional foundation, then we would have received an immediate tax benefit, but by using an LLC we do not. And just like everyone else, we will pay capital gains taxes when our shares are sold by the LLC.”

He also says that this “for profit” structure allows them to make investments that will continue to fuel their objectives.

“This enables us to pursue our mission by funding non-profit organizations, making private investments and participating in policy debates — in each case with the goal of generating a positive impact in areas of great need. Any net profits from investments will also be used to advance this mission….For example, our education work has been funded through a non-profit organization,Startup:Education, the recently announced Breakthrough Energy Coalition will make private investments in clean energy, and we also fund public government efforts, like the CDC Ebola response and San Francisco General Hospital.”

Some of Zuckerberg’s early attempts at philanthropy were also met with controversy, particularly his $100 million gift to Newark schools.  But with $45 billion to experiment with, let’s hope that much of this money ends up doing a lot of good.

Zuckerberg previously signed The Giving Pledge, promising to give away over half his fortune, along with Richard Branson, Warren Buffett and other billionaires.

By timing the latest announcement with the birth of his baby, it seems that Zuckerberg is trying to send a message that he’s not hoarding his personal fortune for the next 100 generations of Zucks.
