The SMD (surface mounted device) LED is a small electroluminescent diode created by deposition. Miniaturization saves significant space and allows grouping several LEDs in the same housing.
It is a simple lamp that emits light by passing current through a compound semiconductor and combining electrons and holes. The excess energy is released in the form of light, achieving the effect of emitting light.
SMT LED is attached to the surface of circuit boards, suitable for SMT processing, and can be reflow soldered. SMT LED solves problems such as brightness, viewing angle, flatness, reliability, and consistency very well. Compared with other packaging devices, it has advantages such as strong vibration resistance, low solder joint defect rate, and good high-frequency characteristics.
It packages more LED chips on a smaller area, uses lighter PCB and reflective layer materials, and requires less epoxy resin to fill the reflective layer. By removing heavier carbon steel material pins and reducing size, the weight of the product can be easily reduced by half. The volume and weight are only about 1/10 of traditional plug-in components. After using SMT packaging, the volume of electronic products is reduced by 40% to 60%. The weight has been reduced by 60% to 80%, ultimately making the application more perfect.
The packaging of straight in LED adopts the form of encapsulation. The sealing process involves first injecting liquid epoxy resin into the LED molding cavity, then inserting the pre welded LED bracket, placing it in an oven to allow the epoxy resin to cure, and then detaching the LED from the mold cavity to form. Due to its relatively simple manufacturing process and low cost, it has a high market share.

A light emitting diode (LED) is a semiconductor device which can create a light source of various colors utilizing a compound semiconductor material such as GaAs, AlGaAs, GaN, InGaN, and AlGaInP. Generally speaking, the LED chips need to be packaged to offer mechanical support, electrical connection, optical guidance, and heat flux path to outside. Following that, the LED packages are integrated into systems as a function unit. An SMD (surface mounted devices) LED is an LED package manufactured by soldering light-emitting diode package structures onto a circuit board utilizing a surface mount technique. The SMD housings are typically fabricated from plastic and can be termed asplone of which is a Plastic Leaded Chip Carrier (PLCC) in which the square-shaped 32-pin package is provided with leads extracting in a T-shaped way from four sides of the package and has a figure dimensioned more compact compared to a DIP package, and the other of which is a Ceramic Leaded Chip Carrier (CLCC) with leads extracting in a T-shaped way from four sides of the package. The SMD LEDs package has advantages in compact design, low cost, high lumen output, low lumen depreciation, efficient heat dissipation, and more flexible in system integration. These LEDs have high reliability performance and are made to work under a broad range of environmental conditions. This high reliability feature makes them ideally fitted to be used under illumination application conditions. SMD LEDs are named by their sizes. SMD 2835, for example, the most well known SMD configuration on the market and offers the best cost / performance among the SMD packages, are called this way because the dimensions of the chips are 2.8mm x 3.5mm. Other SMD chips available on the market including 3014, 3528, 4014, 5050, 5630, 5730, etc. Typical lighting products for LED chips packaged within SMD housings include for example, but are not limited to, LED light bulbs, LED tubes, LED panels, LED linear light fixtures, LED strips, LED downlights, LED flood lights, LED high bay lights. Top SMD LED manufacturers includes FBelec, Cree, Bridgelux, Philips LumiLEDs, Osram, Epistar, Samsung, Seoul Semiconductor, LG, Honglitronic, Sanan, MLS, ETi, Everlight, Nichia, Sharp, etc.astic leaded chip carriers (PLCCs). SMD housings generally feature an LED chip connected to multiple metal leads formed from a leadframe and can optionally include a heat slug. The power is supplied to the circuit board and is delivered correspondingly to p-type electrodes and n-type electrodes of light-emitting diode chips through lead frames of the light-emitting diode package structure to have the light-emitting diode chips produce light. The surface mount package is generally categorized into two types.
