5730 lamp bead
One.
5630 bracket is restricted by foreign patents and widely used in foreign LED market, while 5730 bracket is widely used in China because there is no patent restriction. In fact, these two functions are the same in light effect.
The base of the 5730 patch is also based on the stamping die of the 5630 bracket, so the appearance is the same.
Two.
The difference between the 5630 patch and the 5730 patch is the size specification. 5630 has four welding legs, the length between two welding legs is 56 mm, 5730 has two welding legs, and the length between two welding legs is 57 mm.
Three.
The four solder feet of 5630 chip are all short and thin, and sometimes it is easy to solder because of insufficient solder paste adhesion during the soldering process with mounter, and the defect rate is relatively high; Both sides of the 5730 pin are lengthened by 0.5 mm respectively.
(the luminous surface remains unchanged), the relative proportion of false welding in SMT welding process will be reduced.
Summary:
Difference:
A, domestic name 5730, foreign name 5630;
B, the stitches are different. 5730 has two feet and 5630 has four feet.
Reason:
One,
5630 was first produced abroad, which is the Samsung brand. Later, the same product appeared in China, which is 5730. In order to form a gap without infringement, only 0. 1MM is added to the width, and the pin is designed as two feet, named 5730.
b，
All welded aluminum substrates are used for * * *. The two pins on one side of 5630 are bonded to the pad and welded together, which is no different from that of 5730 with one foot bonded to the pad. Designing four feet into two feet is also cost-saving.
The products of different manufacturers are very different, and the price and performance are very different. But at present, most of the 5630(5730) lamp beads on the market have reached more than 45LM, many have reached more than 50LM, and a few high-end products have reached more than 60LM. In the past, 5630 was actually used in the backlight field, but due to the lack of demand in the backlight field, Korean manufacturers applied it to the lighting field, and the price dropped from 0.2 US dollars to 0.07 US dollars and 0.08 US dollars.
