What documents are required for PCB sampling to the board factory

Time:2023-08-01Views:


Firstly, a PCB or GERBER file needs to be provided, which should include plate making instructions - including specific requirements such as board layers, materials, solder pad process, ink color, etc. Below, we will provide a detailed explanation of some of the main parameters.

 

 


Material: It is necessary to explain what kind of material is required for PCB production. Currently, the most common method is to use FR4, which is mainly made of epoxy resin peeled fiber cloth board.

 

Board layer: It is necessary to specify the number of layers for making PCB boards. (The production layers of PCB boards vary, and the price will also vary. The sampling process for PCB circuit boards is very similar.)

 

Solder resistance color: There are many colors available, which can also be selected according to requirements, usually green.

 

Screen printing color: The font and border color for screen printing on a PCB are generally selected as white.

 

Copper thickness: Generally, the scientific calculation of copper thickness is based on the current of PCB circuits. Generally, the thicker the copper, the better, but the cost will be higher, so a reasonable balance is needed.

 

Is the through-hole covered with solder mask: solder mask is used to insulate the through-hole, otherwise it will cause the through-hole to become uninsulated.

 

Surface coating: with tin spray and gold plating.
