Light Bar PCBA For LED Products


What are the common defects in PCBA processing?
1. The short circuit
That means after soldering there form some solder joints phenomenon between two separate adjacent solder spots, there are some reason are the welding spot is too close and parts arrangement is improper, the solder direction is not correct, solder speed is too fast, solder flux or coating is insufficient, solder paste coating is not good, and the amount of the solder paste is too much.

2. Empty soldering
There is no tin on the tin graben, the parts and base plate are not welded together. The reason for this situation is that the welding graben is not clean, and the parts have poor solderability when the feet are high and the parts are not well welded,point glue operation is not appropriate, so that the excessive glue in the welding cut class, will cause empty welding.The PAD with empty welding is usually in a glossy, round shape.

3. The false welding
There is tin between part pin and the weld groove, but it is not completely caught by the tin.The cause is probably rosin in the solder joint.

Shenzhen Aibixing Industrial now has 4 full-automatic, high-precision, multi-functional SMT machines, which are capable of attaching and mounting QFP, QFN, BGA and other special-shaped elements, At the same time, the SMT elements including 0201,0402 special specifications can be attached, and the chip in the form of 0.3mm high-precision QFP, BGA, QFN and other braid, pallet and tube. 
Equipped with imported full hot air reflow furnace in eight temperature zones to ensure welding accuracy and quality. Our main products of SMT processing include: GPS antenna board, LED internal/ external drive power source, LED outdoor light drive power source, 1.5m LED light bar, LED backlight source, air conditioning controller, LED fluorescent lamp/panel lamp/bulb lamp/spotlight lamp, etc.
