PCB proofing which files need

PCB pre-proofing step is mass-produced, the only accurate proofing to high-volume production, then, to provide accurate proofing documents is particularly important that we all know what documents need to provide it? As well as the documentation provided should pay attention to what issues?
First, the need to provide a PCB or GERBER file, the file to be included DESCRIPTION plate - including the specific requirements of board layers, the material, the pad process, ink color, etc., the following is specifically look at some of the major parameters will be described.
Material: PCB to be described is the production of what kind of materials, the most common is to use FR4, mainly fiber cloth material is epoxy release plate.
Plies: making the number of layers to be described PCB board. (Made by different layers of the PCB, the price will be different, PCB board proofing process is similar to)
Solder Mask Color: There are a variety of colors, can be selected according to requirements, generally is green.
Screen Color: The color of the silk screen fonts and borders the PCB, is generally chosen to be white.
Copper thickness: General PCB circuit current according to the thickness of the copper scientific computing, typically the thicker the better, but the cost will be higher, so that a reasonable balance needs.
Whether through hole solder coverage: through solder vias is to insulate otherwise is to let the vias are not insulated.
Finish: HAL and have gold plated.
Quantity: the number of PCB production to explain clearly.
Summarize the above points, we hope to help everyone PCB proofing. More on PCB-related knowledge, all in the Czech Republic with the official website www.jiepei.com/g602, welcome to log in to learn together!
