Layers
								
									
										
										
											This option is set for how many circuit layers in your design. Please try to design your board with fewer circuit layers because multi-layer board is not cheap.

								Panelization Type
								
									
										
										
											If you require panelized PCBs, you can either define it by yourself in your Gerber file or we can help you define it (for our help please select, “Custom”).

								TG Requirement
								
									
										
										
											The standard FR4 Tg is between 130 – 140°C, the median Tg is 150 °C and the high Tg is greater than 170°C. In the hot state, high Tg FR4 will have better mechanical and chemical resistance to heat and moisture than standard FR4.

								PCB Thickness
								
									
										
										
											Board thickness tolerance is +/-10%. Solder mask and copper plating will make the boards thicker.
