Abbildung 1. SMD-LED-Gehäusegrößen für die Leiterplattenfertigung. SMD-LED-Gehäusegrößen wie 2835, 5050 und 3528 geben mehr als nur die Grundfläche an: Sie lassen Rückschlüsse auf Lichtstrom, Wärmeleitfähigkeit, Bestückungsdichte und die benötigte Leiterplatte zu.
Figure 1. LED PCB example where placement and polarity orientation must be clear. An LED is a polarized component, so it only works when its positive (anode) and negative (cathode) terminals are placed the correct way around. Indicating that orientation clearly on the...
Figure 1. Concert LED glow stick PCB for controllable stage light sticksQuick answer: The glow sticks an audience waves at a modern concert usually aren't chemical sticks — they're small electronic devices with RGB LEDs, a wireless receiver, and a tiny circuit board...
Figure 1. Aluminum LED PCB DesignLED junction temperature is the single variable that determines lumen depreciation rate, color shift, and time to failure. Everything in aluminum LED PCB design either contributes to or reduces junction temperature. A designer who...
Figure 1. Custom Aluminum LED PCBA custom aluminum LED PCB designed for an automotive tail lamp and one designed for a horticulture grow light share the same basic structure — copper circuit on dielectric on aluminum base — and almost nothing else. Power density,...
Figure 1. Aluminum LED PCB ChinaChina produces more than 70% of the world's aluminum LED PCBs. That concentration exists for reasons beyond low labor cost — raw material proximity, process specialization, and a component ecosystem that no other geography has...
Figure 1. Aluminum LED PCB OEMOEM customers for aluminum LED PCBs are a distinct category from prototype buyers and spot-order purchasers. An OEM relationship means the PCB manufacturer produces boards that carry your brand, integrate into your product line, and need...
Figure 1. Aluminum LED PCB QuoteAluminum LED PCB quotes from different suppliers often show a 2× price difference for apparently identical specifications. Some of that difference is margin. Most of it is specification ambiguity — suppliers quoting against different...
Figure 1. Aluminum LED PCB CustomThe term "custom aluminum LED PCB" covers a wide range of requests — from a non-standard board outline to a 3.0 W/m·K dielectric running on 3 oz copper. Not all of these requests are equally straightforward, and some advertised...
Figure 1. Aluminum LED PCB FactoryMost engineers receive an aluminum LED PCB as a finished panel and never see what happened to it between Gerber file submission and delivery. That gap matters, because decisions made during production — dielectric pressing...
