Hence, it is advisable for a designer to know about the information to be included in this file. In this article, we are going to have a look at the following details:Ī fab drawing specifies all the important information such as board outline, layer stack-up, drill chart, and many more required to manufacture a PCB. Whenever a designer wants a circuit board to be fabricated there are a number of ways to communicate all the requirements to the manufacturer. If only a Gerber is provided, the manufacturer may miss out on the additional details concerned with the board.įab drawing along with the assembly drawing are the reference documents required to build and assemble a circuit board. These not only serve as an outline for both processes but also helps in the inspection of the PCB quality. How is a PCB fab drawing different from an assembly drawing?Īs explained above, fabrication drawing is meant for providing details about the manufacturing requirements of a circuit board. On the other hand, the assembly drawing mentions the details about how each and every component will be attached to a board. What all should a board fabrication drawing include? Fabrication drawing in KiCad Factors that impact the cost of the PCB assembly, including.Thus, assembly drawing becomes the basis for the mounting of components and programming the automated component placement machinery. The details that a fab drawing should include are not exclusive. But there are some important ones in this list that should not be missed. ![]() ![]() Let us have a look at these specific details. Board outlineĪny fabrication drawing is incomplete without a pictorial representation of the circuit board. This includes all the cut-outs, holes, different radii, and specific distances that are supposed to be in the actual board. All the dimensions are measured from an origin (0,0) point. This origin point on the fab drawing must be the same as that of the (0,0) point on the NC drill data file. The drilled holes are also pointed out in this drawing with proper symbols that link them to the drill chart. Drill chart Drill chart for fabrication drawing in Altium DesignerĪ drill chart demonstrates all the particular symbols assigned to the drilled holes in the board outline. This chart contains the information related to the drilled hole requirements of the circuit board to be manufactured. Drill symbols may be shapes or textual characters used to represent a hole’s position. These symbols are generated by the PCB layout software.Ī drill chart features specific symbols with respect to the hole size. This chart also displays details about the number of holes of a particular size, whether they are plated or not, what their hole tolerances are, and so on. Just like any other mechanical/electrical drawing, the title block of a fab drawing will consist of the customer name, part number, revisions, any fabrication number specified, and the measurement units. ![]()
