What should be explained to the manufacturer for PCB sampling?
What should the customer explain to the PCB proofing manufacturer when submitting the PCB proofing order? Below, let Xiaobian to tell you.
1. Material: What kind of material is used for PCB proofing, the most common is FR4, and the main material is epoxy resin stripped fiber cloth board.
2. Board layer: indicate the number of layers to be made.
3, resistance welding color: there are many kinds of color, can be selected according to their own requirements, the general is green.
4. Color of screen printing: The color of the font and border of the screen printing on the PCB board is generally white.
5. Copper thickness: The thickness of copper is generally calculated scientifically according to the current of PCB circuit. Generally, the thicker the better, but the cost will be higher.
6, whether the hole is covered with resistance welding: resistance welding is the hole insulation up, otherwise it is not to let the hole insulation.
7, surface coating: spray tin and gold.
8. Quantity: The quantity of PCB sample should be clearly stated.
