six key strategies to make pcb work smarter
In order to maintain a leading position in the competition, the demand for development has increased significantly.
The mentor\'s \"technical Leadership Award\" program is obvious.
Every year, many companies around the world are invited to submit their most advanced designs to a group of independent industry experts for identification.
The shortlisted design after 2012 is more complicated, and the design methods and tools used in the process are much more advanced than before.
This paper introduces that the use of technology promotion function in the future will no longer be a luxury, but a necessity for development.
In a survey by the Aberdeen Group, many leading electronics companies have confirmed that they can meet the six practical designs that actively achieve their business goals.
With the slow recovery of the economic situation, these basic technology practices will become an important part of the development of companies in 2012.
The electronics industry is trying to recover from the economic crisis, and the pressure to provide full support from design to manufacturing processes has also increased significantly.
Electronics companies around the world must bring differentiated products to market faster at lower costs, and this trend will continue due to weak economy.
Even in China, the latest technology needs to be applied to system design and manufacturing support tools to increase productivity.
Here is an overview of six key strategies that can make work smarter, and we believe these six can be key to future development.
Often, collaboration refers to the ability to convert a serial operation into a parallel operation, which has two modes.
The first model is for multiple designers to work on the same design process at the same time.
It\'s not new in the market, but it\'s a big difference in efficacy compared to before.
Designers are always able to operate databases and splits, and each designer works during the design process.
But the database must be re-
It\'s time, though.
It is easy to generate consumption and errors and can eventually shorten the design cycle!
Currently, we can have multiple designers working in the same database at the same time without having to split the database.
It can be used for many design processes such as schematic input, constraint input, management, and physical layout.
In addition, let the designer see the real
The result of other people\'s time.
It not only greatly shortens the design cycle, but also improves the work efficiency and product quality of designers.
Reports from some users show that the technology saves 30 to 70% of the design time.
The company should get similar improvements in order to remain competitive.
The second model is the ability to run several different processes. It is a parallel pattern and a sequence of different forms.
Schematic, constraint, and layout analysis can be parallelized to better improve the productivity of designers and shorten the design cycle.
However, this pattern requires complex design data management with version management, sync, calibration, permissions, which will be explained later in this article.
Typically, companies build and test multiple prototypes to validate their products.
In lab testing, design the PCB, build a physical prototype to determine what changes need to be made and then re-
Design and then repeat the relevant process.
But there are some problems in this regard.
First of all, it\'s very expensive and time-consuming.
If the time listed is very tight, it will miss the best time.
Second, we cannot find all the potential problems.
For example, if you want this product to be used in severe vibration and other harsh environments for many years, however, the \"vibration and heat treatment\" Laboratory may not be able to run long enough to detect long term periodic problems.
There is the same problem with signal integrity.
There may not be very critical conditions in the laboratory.
In future software, such as virtual prototypes, solutions can be simulated.
This can be operated during PCB design and will be applied to more and more fields such as IC, packaging, PCB and system-
Extensive simulation of thermal management, PCB manufacturing and assembly practices, 3D mechanical interfaces, etc. .
Throughout the process, it ensures that the design continues without backup and correction.
More importantly, the software can detect extremely dangerous situations and can simulate possible problems in the lab for several hours, lasting weeks or even months.
Although designers prefer to get real products, and a wide range
A virtual prototype that is executed may be delayed, but it can help shorten the cycle and reduce costs, and improve the productivity of the designer, the quality and reliability of the product.
Cost and time to market are key to many industries.
Even military, aerospace, automobile and other industries are faced with long development time and high cost constraints, and still need to be improved.
Also, PCB designers should keep in mind that their responsibility continues even when the data is in the manufacturing process.
In addition, from the perspective of EDA suppliers, support is more important than the end of the design phase, standing with manufacturers to optimize their production lines and achieve the lowest delivery cost, it\'s more important than making it easy for designers to perform their duties.
Processes have been evolving to help support manufacturers to define rules and practices from the start, with a positive impact on output and reliability.
These DFM rules will be used for the design process.
DFM software can identify problems in the design environment and be corrected by the designer.
Coincidentally, most vendors use the same rules and design software to check the data received.
This ensures that once the design enters the manufacturing process, it can be carried out without design rework.
Once the design passes through an intelligent interface such as the ODB, the manufacturer can use the software for production when entering the manufacturing process
Line modeling and optimization.
When running the production line, the software will continue to monitor on-
Problems such as part delivery time, machine downtime, and product traceability.
Even if a quality defect occurs, it can ensure that the device or process is tracked and highlighted with a low failure rate.
For differentiated products that can beat competitors, enterprises must use the latest and most advanced technologies to compress more functions into smaller spaces while meeting positive market opportunities, this will be more important in the future.
Integrated circuit technology will be continuously improved in high density and high speed.
Printed circuit board manufacturing techniques such as HDI/small holes can improve the density, but the design is also more complicated.
In the face of the increasingly complex design environment, how do we maintain and improve the efficiency of designers?
Not long ago, for example, a typical design might include some high
A speed network that meets the length and adjacent rules.
Designers can manage these networks easily.
Now, the large reading design is over 50% high.
Network speed, even some up to 90%.
Another example is the increase in the number and density of the BGA pins.
It\'s a challenge. out PCB.
This situation raises a complex problem where productivity will decline without advanced design tools and time to market will be significantly extended.
Multi-disciplinary cooperation is required for product development and delivery.
In the field of electronics.
We have experts in integrated circuits, packaging, FPGA, RF, simulation and digitalization.
In addition, we have shell design and CAE analysis engineers in the mechanical field.
In addition, we have procurement, supply chain and manufacturing personnel as well as embedded software developers.
These require effective cooperation in the R & D process.
This is a cooperation between paper and e-commerce.
Previously Mail, now mostly via e-media, but it\'s still a problem for team members to save a lot of data.
In fact, most of the interaction is a kind of consultation.
For example, if a mechanical engineer finds a component on a PCB that interferes with the physical product housing, then he can change the position of the component.
It will take a gradual form (
Only when replaced)
Advise the PCB designer.
The PCB designer must then check and confirm the proposal in sequence.
Mentor Graphics and users have developed step-by-step changes in performance as standard EDMD with approval from ProSTEP.
The proposal will be shown in the figure, which will take, reject or make better suggestions based on the actual situation of the PCB in question.
This will continue until an agreement is reached and the mechanical and electrical database will be updated.
This is just an example of full electronic cooperation in actual operation. Top-
An electronics company believes that managing their workflows and databases is key to future success.
For design team members, both locally and scattered around the world, a valid license needs to be created and the company\'s most important assets are strictly managed.
The database administrator puts qualified information components into the approved management infrastructure and can be evaluated by the designer. Pre-
Designed PCBs can be added to the database and used in the future as the PCB design progresses, schematic diagrams, constraints, and data are created.
Data management is very complex and requires the creation of a special infrastructure system for IP management.
Dates edited by different team members will face version management and sync issues.
Companies can hire agents to design part of the product and share only part of the IP, which will rule out complexity by using a standard PLM system.
This means that mature product development, the final design data must be uploaded to the company\'s PLM, ERP system for lifecycle management.
