Q:What does "1210" mean in patch LED?

1210 represents the size of the LED package specification (size, specification), and represents the length and width of the resistanceSpeed adoption!!!

Q:Patch LED light does not flash, why?

Hit the meter on the buzzer and measure the patch individually. If the flash is a patch, the light goes off.

Q:Patch LED market conditions

With good market expectations for the future status of SMD LED, all the major manufacturers have launched their own SMD LED development planning and prototype products, all of a sudden, SMD LED market showing a flourishing and lively atmosphere of contention of a hundred schools of thought.

Q:Indoor full color LED display module and LED what is the difference between a full color?

The classification of the LED display according to the installation environment: indoor LED display screen, semi outdoor LED display, outdoor LED display; according to color: color LED screen, dual color LED display screen, LED display screen, the color LED display screen; according to the functional area can be divided into graphic screen, screen, screen, screen, digital dot matrix digital hybrid screen.

Q:Production of a number of substrates, the use of SMD LED lights, red lights and green lights are not bad, blue lights appear mass dark, do not know why? Is the LED blue light material easy to use dark?

The pressure drop of the blue light is greater than that of the red light and the green light. If the series connection is the same as that of the green light and red light, the current limiting resistor will tend to dim

Q:Such as title, please have welding patch LED lamp experience expert guidance, do not search from the Internet to the theoretical knowledge, thank you!

Recommend to communicate with older employees, they will have a lot of welding experience

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

Pin forming, 1, LED pin molding must be completed before welding, bending angle must be more than 3mm of the gel to bend the stent. Pin over 2 times in the same place can not fold number, pin bent to 90 degrees, and then returned to the original position for 1 times; 2, pin forming must use fixture or by professional personnel to complete the first, pay attention to avoid the epoxy body caused by excessive internal wire fracture; 3, to ensure the distance between pin pin forming consistent with the circuit board; 4, when LED has good welding in the welding process or after, please don't bend light feet, to avoid damage to the lamp.

Q:What should I notice when I want to solder 1206 LED patch type luminous tube on fine copper wire?,

The peak reflow temperature: 260 degrees or below this temperature. (surface temperature) 2 temperature over 210 DEG C required time: 30 seconds or less than this time. 3 reflow times: no more than two times. 4 after reflow, LED needs to be cooled to room temperature before contact with colloid.

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:What is patch SMD-LED?

Semiconductor wafers consist of two parts, one is P type semiconductor, in which the hole dominates, and the other end is N type semiconductor, which is mainly electronic here. But when the two semiconductors are connected, they form a P-N junction between them. When the current passes through the wire acting on the chip, the electrons are pushed into the P region. In the P region, electrons combine with the hole and then emit energy in the form of photons, which is the principle of LED luminescence. The wavelength of light, that is, the color of light, is determined by the material that forms the P-N junction.
