What does it mean to have a mature design?
Mature design is a product engineering approach. It is a systematic approach to optimizing the product development process to achieve goals. For PCBAs, it guarantees that quality products are manufactured in a cost-effective manner and delivered to meet deadlines.
What are the aspects of mature design? According to the summary of the project, we can summarize the following points, including: Design for Manufacturing (DFM), Design for Assembly (DFA). Today, let's take a look at what they mean.
OneDesign for manufacturing
Because the entire PCBA assembly process needs to be carried out by a professional SMT chip processing factory, but in general, the manufacturer is not involved in the front-end design of the product
1. Analyze the circuit, design and layout of the printed circuit board and give references.
2. Make sure the package conforms to the reference mark in your bill of materials (BOM).
3. Close analysis of materials, tools, environments, tests and tolerances to give data.
The goal of this process is to standardize the manufacturing process to create a high-quality product that optimizes manufacturing costs and reduces the risk of failure or inefficiencies in the assembly phase. Other benefits include increased PCB yield, better performance and cost, and improved production stability and availability.
Second, assembly design
Design for Assembly (DFA) shares the same goal as the design for manufacturing process, but focuses on optimizing the ease of assembly of a product. It ensures smooth assembly of double-sided mount machining and meets its physical layout rules before building the first piece of PCBA, optimizing plastic enclosures and enclosures, sheet metal or CNC machined parts during the production assembly phase.
Despite increasing automation, your products (or their parts) can still be assembled by humans. Invest in assembly design:
1. Optimize assembly time.
2. Reduce the error rate.
3. Improve assembly yield.
4. Reduce the content of labor
