FR-4 Dielectric Constants | 4.5 (2-Layer PCB) | 7628 Prepreg 4.4 3313 Perpreg 4.1 2116 Perpreg 4.16 | |
Maximum Dimensions | FR4 PCB: 670 × 600 mm Rogers / PTFE Teflon PCB: 590 × 438 mm Aluminum PCB: 602 × 506 mm Copper PCB: 480 × 286 mm | These limits apply to PCBs with thickness ≥ 0.8 mm. The thinner FR4 PCBs are 500 × 600 mm maximum. 2-layer FR4 PCBs can reach a maximum size of 1020 × 600 mm. | |
Minimum Dimensions | Regular: 3 × 3 mm. Castellated / Plated Edges: 10 × 10 mm. | These limits apply to PCBs with thickness ≥ 0.6 mm. Manual review required for thinner PCBs. Panelization is recommended for small-sized boards. | |
Dimension Tolerance | ±0.1mm | ±0.1mm(Precision) and ±0.2mm(Regular) for CNC routing, and ±0.4mm for V-scoring | |
Thickness | 0.4 - 4.5 mm | Thickness for FR4 are: 0.4/0.6/0.8/1.0/1.2/1.6/2.0 mm (2.5 mm and above are for 12+ layer PCBs only) | |
Thickness Tolerance (Thickness≥1.0mm) | ± 10% | e.g. For the 1.6mm board thickness, the finished board thickness ranges from 1.44mm(T-1.6×10%) to 1.76mm(T+1.6×10%) | |
Thickness Tolerance (Thickness<1.0mm) | ± 0.1mm | e.g. For the 0.8mm board thickness, the finished board thickness ranges from 0.7mm(T-0.1) to 0.9mm(T+0.1). | |
Finished Outer Layer Copper | 1 oz / 2 oz (35um / 70um) | Finished copper weight of outer layer is 1oz or 2oz. | |
Finished Inner Layer Copper | 0.5 oz / 1 oz / 2 oz (17.5um / 35um / 70um) | Finished copper weight of inner layer is 0.5oz by default. | |
Soldermask | Green, Purple, Red, Yellow, Blue, White, and Black. | We use LPI (Liquid Photo Imageable) solder mask. This is the most common type of mask used today. Heat-cured ink soldermask is usually found on low-cost, single-sided PCBs. | |
Surface Finish | HASL (leaded / lead-free), ENIG, OSP (copper core boards only) | FR4 has all three finishes available, 6+ layers and RF boards only have ENIG. Aluminium core boards only have HASL. Copper core boards only have OSP. |
