Q:How can I install the patch LED lamp belt on the wood chip casting board? With double-sided glue will be hot, and can not use the clip on the screw, what should I do?

With double-sided adhesive, the temperature will not be very high. So it won't fall either. That's how I got it. It took me more than half a year, and I didn't have any problems

Q:What is the difference between SMT LED packaging with silicone and epoxy resin transparent package? What is the market situation of these two types of packaging?

To package with epoxy SMD beads are used in a lot of outdoor display, because the epoxy adhesive with good adhesion to all better PPI support in outdoor use, our high quality and inexpensive epoxy epoxy call for samples

Q:What is the principle used in SMD LED lamp, should pay attention to what the problem?

LED installation method 1, don't install the LED pin in 2, under the condition of deformation in printed circuit board when installing LED, circuit board hole center distance and LED pin center spacing should be the same, if the hole spacing will make the lamp feet have residual stress and welding...

Q:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?

They differ in form and belong to the SMDLED category. Encapsulation uses liquid silicone and epoxy resins as well. The patches are basically made of epoxy resin. Relatively speaking, the amount of liquid silica should be relatively large.

Q:How does the LED placement lamp distinguish the positive and negative poles? There is no sign on the light. Thank you

The light emitting diode is fixed regardless of color. The light emitting diode 1, line: foot length is positive, the negative is short. The electrodes inside the tube can also be carefully observed, while the smaller ones are positive and the large ones, similar to the bowl, are negative. 2, SMD: overlooking the side with the color line is negative, the other side is positive.

Q:How do led patches measure good or bad?

The patch LED is also called SMD LED. Its principle of luminescence is to pass the current through the compound semiconductor. Through the combination of the electron and the hole, the excess energy will be released in the form of light to achieve the effect of luminescence.

Q:LED patches have several ways of welding. Which ones can be reflow? What can be done by eutectic welding? Is the welding of viscose and lens material is required?

Of course, the reflow soldering is generally divided into three sections of six principle of oven temperature is 150 degrees, 190 degrees, 220 degrees, with a PC lens products can not reflow soldering, PC deformation at 150 degrees, can be heated by a soldering paste on the heating plate.

Q:Led lamp and Led patch two what is the difference between ah, the feeling is a patch of long service life, whether or not? 5-10 meters pan area lighting lamp selection Everbright shaped or patch shape?

First of all, I want to say, in the same light emitting chip case, two is not what were, just a different process is a DIP plugin, a SMD patch process, the 3 floor of the right, just some high grade patch.

Q:What is patch SMD-LED?

SMD LED is the surface mount light emitting diode. It is a solid state semiconductor device that converts electricity directly into light. The heart of LED is a semiconductor wafer, one end of which is attached to a bracket, one end is negative, and the other is connected to the positive electrode of the power to encapsulate the entire wafer with epoxy resin.

Q:Patch LED features

Without heating time, lighting is faster than general light (about 3 ~ 400ns).The electro optic conversion efficiency is high, the power consumption is small, and the energy consumption is about 1/3 ~ 1/20 than that of the bulb.
