According to uncompleted statistic, there is over 800 flexible strip lighting company in Shenzhen China, we don’t have the data in the whole China. For led strip lights manufacturing company, they choose this product because this product is very each to assemble. Or we can say, it achieve automation at utmost. From the flexible PCB to SMT, from epoxy glue to aging test, the most process can be made by machine. We can say, most flexible Strip Lighting Company can be the qualified supplier, but, let’s see, I am here to open the box. PCB, most led strip lights manufacturing company choose FPC, the quality can be different, you can buy 0.03USD per meter, and you also can buy 0.6USD each meter. The secret is the copper amount. It concerns the heat dissipation. LED, you can buy 0.005USD led with alloy stent, also you can buy the 0.05USD led with EMC stent. Resistance, actually this material can be OK for quality, only a few suppliers can use the fake one. But the circuit is important. Epoxy glue or silicone, it’s OK, but the cost is also different, the importance is RoHS compliance. At this moment, as the developing of the whole industry, we are glad to see there are more creative products from the led strip lights manufacturing company, they update the process of epoxy glue or silicone tube to extrusion mold. It’s a good change, the IP grade will be better. Anyway, the quality is different, if you can get the BOM sheet from your supplier, then you can deem they will be trustable to be qualified. Business is a long-term problem, we have to face many problems with our suppliers and our customer, but solving ways will test our intelligence.
