What is the difference between GOB module (display) and LOB module (display)?

What is the difference between GOB module (display) and LOB module (display) process?
With the wider and wider application of LED display, more and more friends are paying attention to the LED display's The development of science and technology, process progress. Recently, there are a lot of peers and customers ask the author what LOB process is. Because our company is China's first to master the GOB gluing technology manufacturers, so our company in the see a lot of friends ask LOB process technology, spend a little time and energy to see what is LOB process, the results, so that most of our friends are disappointed, LOB technology!

Is GOB technology, is just another way of saying the same process invented by peer competitors in order to circumvent patent restrictions.

Now formally on GOB - glue on board, lamp surface filling technology, and LOB - lamination on board (peer competitors called lamination), in the end, what is the difference between the two processes?), in the end, what is the difference between the two processes, officially make an official answer.

First, GOB (glue on board)

This kind of name is our company in just research and invention of this kind of process technology When the name, meaning whether indoor or outdoor LED module In particular, mainly for outdoor LED modules, we are a technology for the surface of the lamp glue processing. The process is not allowed due to the current market conditions, our company has not been announced, but with a few engineers leave to start a new company situation leads to the loss of GOB process, our company still adhere to the standards promised to new and old customers, that is, brightness, color, waterproof, anti-collision and so on performance performance to adhere to the standards, so that customers who choose our technology of our company's service is a real evaluation.

Second, LOB (lamination on board)

This kind of name is peer competitors see our company in the new technology new technology new patent promotion In the case of the same operation, the same operation of a different argument. In fact, but where friends and the labeled LOB process factories to communicate, and ultimately will find that it is only the same process of the new call only. Are in the lamp surface for the glue treatment, in order to achieve the purpose of waterproof anti-collision a process step only.

Third, the essence of GOB and LOB
Our company in order to online this in order to avoid patents and eliminate process similarity so-called “another way” approach, our company this time to make sacrifices, this GOB technology process points to the public.

1.Lamp surface filling technology

The core premise is that the LED module itself has excellent performance.The first demand for this process arises from the need for low-brightness small-pitch LED modules need to be applied to outdoor. When the customer puts forward this demand, our company thinks that the most important method of waterproof is to fill the glue, but the lamp bead of indoor module is not waterproof, so our engineers put forward the idea of covering the lamp together with the glue. After night and day experiments, we finally found that the OPTOTECH
We finally found that the high quality glue, such as OPTEXX, after our experiments with a specific proportion of the proportion of the lamp surface including the lamp beads together with the full irrigation processing, and then after the room temperature cooling and solidification of the processing effect is more ideal. Since then, after many experiments, we found that the use of specific sizes and specifications of the module to match the mold for the glue filling process of the LED module in the glue filling process after drying the effect is better. But at the same time our company found that the glue natural drying process, on the foot, pad, PCB circuit board tens of thousands of cases, and ultimately through thousands of experiments, our company came to be able to carry out the lamp surface of the LED module, first of all, must have their own performance, which includes, PCB line must be 1.6mm thickness or more, solder paste must be high temperature solder paste (with the party or Vitol 0.4% silver-containing high-temperature solder paste above), the bead must Guoxing or Jingtai. Lamp beads must be national star or crystal Taiwan series. This series of hardware configuration to ensure that this step of the process before the filling of the hardware standard, in order to prevent the emergence of dead lights, “caterpillars”, light board deformation and other bad situations.

2. The aging of the lamp surface before filling the glue must ensure that the sufficient length of time Conventional LED module, we generally only need to age 4 hours is enough. If it is to GOB (a few peers called LOB) processing of LED modules, we generally want to ensure that the aging more than 24 hours. The reason is very simple, once the surface of the lamp filling processing, and then the occurrence of conventional modules seen dead, “caterpillar” and other phenomena, the surface of the lamp already does not have the basis for repair. After all, I have been treated after the light surface, has been waterproof and anti-collision, how to repair? Even if you spend a lot of effort to repair, the traces of repair has been declared this LED module for defective products. And our company is a pursuit of LED modules and LED display perfect product company, such defects for my company quality control can not be tolerated, so our hardware raw materials, are the industry's top level materials.

3. Edge cutting process

Must reach 0.01mm level.

After a series of operations such as fixture comparison, lamp surface filling, natural drying, etc., we need to cut the corners of the GOB module to deal with the overflow of glue. Conventional factory cutting means for milling cutter cutting or molybdenum wire

Cutting. Our company adopts high precision laser CNC cutting, the precision is 0.0001mm, the purpose is to ensure that the LED module production process, the foot of the precision is not enough, if the error is not precise enough, will be 1/4 foot cut off, a module other 99.99% of the area of the performance of the perfect, because of a foot of the problem of the scrap, it is really not worth the loss. So our cutting precision from a variety of costs after trial and error, and finally selected for the 0.0001mm error CNC cutting.

After a period of market competition and upstream and downstream suppliers to integrate the elimination, our company decided to our patented technology to the public, the purpose is to unify the market
Technical standards, in order to set the record straight.
