Q:Welding method and notice of SMT LED
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:The quality of the LED patch module
Chip manufacturers, the top chip mainly from the United States, Germany, Japan and South Korea and so on. But on the mainland LED module manufacturers to use the vast majority of chip from Taiwan, of course, there are a lot of use of chip, market positioning, the main users of the product features with the manufacturers and government policies, different chip manufacturers are different its stable performance. Maybe you will ask why not CREE, OSRAM, Nichia, first of the world's top chip manufacturers have fixed target market positioning, such as defense orders, and said, specially import a little CREE chip manufacturing module, it is also not cost-effective; and if the driver is not supporting the raw materials, it can not be completely play the advantage, so is also a great waste.
Q:Patch LED market conditions
Chinese suppliers also offer mature, but less profitable two-color and trichromatic products, which are mostly used in backlighting, appliances, consumer products, consumer electronics and display. Despite low market demand, vendors continue to offer sideview SMD LED, including 335 (4008), 020 (3806) and 215 (2810)
Q:What does patch LED light mean?
The screen is divided into standard lamp and patch type, the light emitting diode lamp is inserted into the circuit board, and the patch is a patch welded on the circuit board. Two light sources are not the same. If only light, not so clear.
Q:Is the forward voltage drop of the patch LED too large or too small?
The pressure drop in the normal range is generally better. The smaller the pressure drop, the lower the power dissipation. The more you save the electricity bill.But not to say that the smaller the better, not in the normal range of low pressure drop products may be defective.In addition, the uniformity of the LED pressure drop is also important.
Q:How do led patches measure good or bad?
Use the two stage tube test of the multimeter, the red pen is connected, and the black pen is negative. If there is a bee, the sound is bad, and if the light is bright, it is good
Q:What is patch LED?
Patch element. Very small, no pins, soldered directly to the circuit board. For example, the keyboard lights in a mobile phone are used in this way.
Q:LED light SMD LED package in what form, trouble you under the guidance of...
The LED chip has bumps and is welded to the PCB board using FLIP CHIP to packaging technology.LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core role finally, the installation shell, so the seismic performance of LED lamp is good. Field of application involves mobile phones, desk lamps, household appliances and other daily household electrical appliances and machinery production.
Q:What determines the brightness of the patch LED?
Lamp brightness level itself, is also in the rated current situation, its brightness
Q:Notes on patch LED
Storage bags are sealed and stored at a temperature of <40 DEG C.
