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 to detect LED SMD beads
Resistance voltage ordinary pointer table 1.5V in general, and some only in the high resistance file (*10K file) with 9V or 15V battery, so the pointer table to measure LeD beads to hit the highest resistance profile measurement, otherwise useless, of course, at this time the brightness is very small, can not see, can only to judge the positive and negative resistance values see.
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: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 same, stick pieces is an early product, stick pieces than patch mature, stick pieces of my lamp has almost can not see what changes for three years with only a patch of brightness, years have been feeling a lot of dark. I believe the quality will be good soon.
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: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:Patch LED manual welding, how can welding not burn lights?
Recommend to communicate with older employees, they will have a lot of welding experience
Q:Led lamp and Led what is the difference between the two patch! Ask for detailed explanations of the differences!
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:How many voltages and how many W drivers are used in series and parallel connection with 20 1W patches LED?
The voltage problem is determined by the size of your POWER SUPPLY, according to Ohm's Law: the series voltage is accumulated and the shunt voltage is the same.
