Q: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.
Q:Which is good for LED patch and LED bulb?
The LED patch is the same as the LED bulbLED (light emitting diode) patch (package)The LED patch (SMD) is made of FPC circuit board, LED and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.LED bulbWith the LED patch or LED plug-in LED (light emitting diode), series or parallel, driving power supply, making a combined shell lampshade capable of converting electrical energy into visible solid semiconductor devices, which can be directly converted into electricity to light.
Q:The quality of the LED patch module
Luminous efficiency。 The LM value per watt is called luminous efficiency. This is an important criterion for judging whether LED is energy-saving or not. The incandescent lamp is about 14.4LM/W, the fluorescent lamp is about 51LM/W, the neon lamp is 43LM/W or so, and the LED is up to 150LM/W at present, but most of the LED light effects in our country are in 60~100LM/W. It should be noted that only the white light can achieve such high luminous efficiency in LED, and that red, yellow and blue are generally relatively low (mainly related to human visual definition). But compared with neon light, there is no heavy metal pollution, easy to maintain.
Q:How to install the patch LED lamp band?
Installed indoors, you can directly tear off the stickers on the 3M double-sided adhesive surface, and then fix the light bar where it needs to be installed. Just press it with your hands.
Q: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.
Q:Patch LED market conditions
Conventional monochrome SMD LED package sizes are 1206 (3215), 1004 (2510), 0805 (2012) and 0603 (1608). Chinese manufacturers can provide a minimum size of 0603, the thickness of only 0.3 mm. A smaller LED of 0402 (1005) is still in trial manufacture
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:Patch LED beads can be bought in what place?
Many LED packaging plants do patch LED, you can find the relevant manufacturers to contact, or go to the local electronic components market according to your needs
Q:Notes on patch LED
Moisture proof, in order to avoid the products in the transport and storage of moisture, SMD LED packaging is moisture-proof aluminum packaging, and packaging bag containing a desiccant and humidity card, mainly to control the desiccant bag, humidity, humidity card is mainly to monitor the packaging bag of humidity
