LED SMD vs LED DIP


LED SMD (Surface Mount  Device)

This is newer technology. SMDs can be made much smaller and a lot thinner because the part is only soldered to the “surface” of one side of the circuit board.

LED DIP (Dual Inline Package)

This method of manufacturing is attaching a part to a circuit board is known as “through the hole”.

LED SMD Vs LED DIP

 

Most DIP screens have a separate LED (R, G, B) for each of the three main colours: Red, Green, and Blue. Some have an extra red LED, forming one square pixel from 4 lights. SMD LED screens are usually use 3-in-1’s, which are smaller, thinner, and brighter. There are DIP 3-in-1 bulbs, but they cost more and are naturally bigger than their SMD equivalents. SMD LED light source is a very small with light chips enveloped in epoxy resin. Generally speaking, the voltage per SMD LED is 2-3.6V, current 0.02A-0.03A, with very low voltage, current, and power consumption. Equivalent to 1/8 of incandescent light, 1/4 of traditional light. Under proper current and voltage conditions, the life span of SMD LED can reach 100,000 hrs. Compared to other LED tubes like Dip LED, the optical decay is reduced from 10% to 5% in 1000hrs. The life span of SMD LED is longer due to Automatic Equipment’s heat emitting process. Mainly adopted 3528 and 5050/5060 SMD high brightness chip, single SMD LED over 5.5lm/1800MCD 3-in-1 SMD screens look better. They are a lot brighter, the colors are more vivid and true, and the picture is crisp and sharp. DIP displays are still cheaper to make, and because SMD is a newer technology, DIP on average has a longer lifespan or shelf life. Quality control in the factory makes all the difference, especially with SMD being so much smaller. Machines that are decades old, or even can assemble DIP circuit boards by hand. SMD with no pin anchored through a hole, requires newer more-precise assembly methods.
