Design for manufacturing and assembly (DFMA)
Design for manufacturing and assembly - short version
A simultaneous engineering process designed to optimize the association between the design function, manufacturability, and ease of assembly.
Design for manufacturing and assembly - long version
Design for manufacturing (DFM) is the art of general engineering of product design, so that they are easy to manufacture. The basic idea that exists in almost all engineering disciplines, but, of course, the details are very different depending on the manufacturing technology. Here are some examples:
· Design for manufacturing ICs.
· Design for manufacturing PCBs.
· Design for manufacturing CNC machinery parts.
As described above that DFM is a technical term and the design abbreviation for manufacturing, which means that a given design (PCB) is verified for all aspects and verify that the data provided has no problems.
DFM aims to avoid:
-Product designs that simplify assembly operations, but require the most complex and expensive components
Designs simplify the manufacture of components while complicating the manufacturing process
AND designs that are simple and cheap, but they are difficult or expensive service and support.
There are several controls that are performed to find the problems where appropriate, these controls are called DFM controls analysis. Below are the main brakes that run before PCB manufacturing.
· Signal of check layers.
· Power / control.
· Welding mask controls.
