Q:What is patch LED?
LED is usually the lead pins form, need to be drilled on the printed circuit board, the LED pin is inserted in the hole, welded with wave soldering machine; and the patch type LED is used in welding surface, flat welded on the circuit board.
Q:SMD LED lamp working voltage?
Single chip of 1 watts, more than a lot, different colors, the voltage will be different. White is usually 3.0-3.6V.* in addition to their working voltage, working current is more important parameters, once the flow, it will burn out.The LED lamp. With chips is variety, many tricks, they can be connected in series and parallel. The voltage is divided into high voltage, low voltage and medium voltage
Q:Is the forward voltage drop of the patch LED too large or too small?
If you have to be good or bad, then I can say "small" to you,Some clients have strict requirements for this
Q:How to install the patch LED lamp band?
More attention is paid to the lamp with waterproof and the installation of a solid in the outdoor installation, outdoor installation often adopts the mode of fixed card slot, need to cut and connected place, and indoor installation, just need another with waterproof glue, waterproof effect to consolidate the connection point.
Q:SMD LED specification
SMD LED specification:(1) metal stent type: 0402, 0603, 0805, 1206, 3mm, 5mm, 6mm, 8mm, 10mm and so on.(2) metal support (commonly known as small butterfly) type: 2mm, 3mm and so on.(3) TOP LED (white shell) type: 1208 (30*20), 1311 (35*28), 1312 (35*32), 2220 (55*50) and so on(4) side light LED:0905 (22*12), 1105 (28*12) 1605 (40*14) and so on.
Q:What are the storage requirements of SMT patch LED (LED)?
Keep in storage- the original sealing bag packing in the condition of the <40 C and <90% RH degrees for 12 months, more than the storage period will bake.Please check the leak before opening the packing bagIn opening the sealed bag, should be placed in SMD LED and C 60%RH. < < 30 degrees under the conditions in the above conditions, SMD LED must be in the open package using reflow within 24 hours. If placed more than 24 hours, you need to bake- baked, SMD LED in C + 80 degrees 5 degrees C and <=10%RH relative humidity in the oven for 24 hours• remove the pouch before baking, and do not open the oven door frequently
Q:How to detect LED SMD beads
Now the LED lamp, drop it in general about 3V, so the general multimeter is not measuring it.
Q:The quality of the LED patch module
Quality of circuit board. In the same quality of LED, the quality of PCB will have an important impact on the life of LED. The circuit board is divided into aluminum plate, glass fiber board, semi glass fiber board and paperboard. The quality of aluminum is the best, the best cooling effect, but the cost is too high, the domestic manufacturers generally only in high-power LED products use, LED module manufacturers generally use cardboard, semi glass fiber and glass fiber board. Module, piranha, straw hat module monochrome is generally used in cardboard or semi glass, commonly used glass fiber or semi SMD glass fiber board. Colorful and full color module series generally at least half of glass fiber, so as to match.
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:What is the difference in performance between the LED plug-in and the LED patch?
The cooling of the plug-in is not good, because the plug-in's lamp foot, in order to save costs, generally use iron plus coating, heat conduction is not very good.The strength of aluminium alloy is not enough, it is easy to break, and copper is expensive.Relatively speaking, the patch is good, because the heat is welded on the PCB, copper or direct aluminum substrate cooling, patches near.Otherwise, why do high-power patch it?!SMT direct placement machine, a high degree of automation, low rate of bad.
