HASL Lead Free LED PCB Board Assembly Multilayer Circuit Board
OEM PCB Assembly PCB Manufacturer Multilayer Circuit Board PCBA
Aluminum printed circuit boards (PCBs) are metal-based, copper-clad laminates with a good heat dissipation function. Generally, a single
Aluminum PCB is composed of a three-layer structure: a circuit layer (copper foil), an insulating layer, and a metal base layer. Aluminum PCBs are commonly found in light-emitting diode (LED) lighting products. There are two sides—the white side is for soldering the LED pins, and the other side is the natural color of aluminum.
Generally, the thermal conductive paste will be applied to come into contact the thermal conductive part. Very few applications are multi-layer aluminum PCB boards, which can mix-press ordinary multi-layer boards like FR-4 (glass-reinforced epoxy) with insulating layers and aluminum core.
