High-TG PCB
| Number of layers | 4 –14 layers standard, 18 layers advanced |
| Technology highlights | Multi-layer boards with a higher connection pad density than standard boards, with finer lines/spaces, smaller via Holes and capture pads allowing microchip to only penetrate select layers and also be placed in surface pads. |
| HDI builds | 1+n+1, 2+N+2, 3+N+3 |
| Materials | FR-4 high performance, Halogen-free FR-4, Rogers 4350B |
| Copper weights (finished) | 18um – 70um |
| PCB thickness | 0.40 mm – 3.20 mm |
| Maximum dimensions | 600 mm x 450 mm; dependent upon laser drilling machine |
| Surface finishes available | OSP, ENIG, EESPIG, HAL, LFH ASL Immersion Tin, Immersion Silver, Electroplate gold, Gold Fingers |
| Minimum mechanical drill | 0.15 mm |
| Minimum laser drill | 0.10 mm standard, 0.075 mm advanced |
| size | 10-20 |
Aluminum PCB are metal-based, copper-clad laminates with a good heat dissipation function. Generally, a single Aluminium PCB is composed of a three-layer structure: a circuit layer (copper foil), an insulating layer, and a metal base layer. Aluminum PCB 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.
