FAQ

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
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?
SMD patch products basically can be used in reflow soldering, especially a little note here that the eutectic welding is the connection between the chip and the substrate support or specifically, is the bottom of the chip after completion of production of coating material and a layer of Sikkim alloy, and then set up a heating zone in solid crystal machine package in time and a temperature of about 300 degrees, the realization process of the chip at the bottom of the Sikkim alloy melt and silver plated layer connection bracket, and a clear distinction between reflow.
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.
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.
LED light SMD LED package in what form, trouble you under the guidance of...
Draw your own line, mm is replaced by mil on the line, with vernier caliper measurement, or know the model, count the number of mil. For example, 5050 is a close square with a width of 5.0mm*5.0mmInline LED (such as straw hat lights, 5mm), piranha LED, surface mount LEDSinglechip collection from hardware to software chm
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.
How many volts is a single LED on the LED patch band?
The single LED on the LED patch band is around 3.3V.LED light emitting diode, which is a nonlinear component, its operating voltage (tube pressure drop) is also different: ordinary red LED about 1.5 V; ordinary green LED about 1.8 V; bright white LED up to 3.3 V or so.
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
