Do you know what documents PCB needs from the manufacturer?
printed circuit boards, also known as printed circuit boards, are providers of electrICal connections for electronIC components.
printed circuit board is usually represented by "PCB", not "PCB".
PCB design is mainly layout design; The main advantage of using circuit board is to greatly reduce wiring and assembly errors, and improve the automation level and production labor rate.
printed circuit board can be divided into single panel, double panel, four layer board, Six layer board and other multi-layer circuit boards according to the number of circuit board layers.
As PCB is not a general terminal product, the definition of its name is slightly confused. For example, the motherboard for personal computers is calLED the motherboard, but not the circuit board. Although there are circuit boards in the motherboard, they are not the same. Therefore, when evaluating the industry, they cannot be said to be the same. Another example: because there are integrated circuit parts loaded on the circuit board, the news media call it IC board, but in fact it is not the same as printed circuit board. The printed circuit board we usually refer to the bare board - that is, the circuit board without upper element devices.
What documents pcb sends to the manufacturer
It is better to use GERBER file and PCB source file.
Most PCB design engineers are used to sending PCB files directly to PCB factories for processing after they have been designed. However, the most popular practice in the world is to convert PCB files into GERBER files and drill data and then submit them to PCB factories. Why should we "do more than this"?
Because PCB production engineers and PCB design engineers have different understandings of PCB, the GERBER file converted from the Pcb factory may not be what you want. For example, when you define the parameters of components in the PCB file during design, you do not want these parameters to be displayed on the finished PCB. Without your explanation, the PCB factory follows the lead and leaves these parameters on the finished PCB. This is just an example. If you convert PCB files to GERBER files yourself, you can avoid such events.
GERBER file is an international standard photo format file, which includes RS-274-D and RS-274-X formats. RS-274-D is called the basic GERBER format, and a D code file must be attached at the same time to fully describe a drawing; RS-274-X is called extended GERBER format, which contains D-code information. Common CAD software can generate these two formats.
How to check the correctness of the generated GERBER? You only need to import these GERBER files and D code files in the free software Viewmate V6.3 to see them on the screen or print them out through the printer.
Drilling data can also be generated by various CAD software, generally in Excel format, and can also be displayed in Viewmate. No PCB can be made without drilling data.
PCB manufacturers, PCB designers, and PCBA processors will explain to you what documents pcb sends to the manufacturer for.
