Globalization and contract manufacturing are two important trends that shaping modern manufacturing. Companies are using contract manufacturers (CM) for different purposes – design, component supply, assembly, fabrication, etc. In some industries such as electronic, contract manufacturing is an absolutely vital part of your product success. My attention caught by EE Times article: 5 Don’ts and Do’s for Working with a Contract Manufacturer. It is short and sweet – I certainly recommend you to have a read.

Here are my favorite two recommendations – prepare detailed documentation and design for manufacturing.

Prepare Detailed Documentation — I don’t think it’s possible to under-communicate when it comes to providing instructions to a CEM. The more CAD files, schematics and specs you deliver with your design the better, from our perspective. And don’t forget to provide a comprehensive bill of materials with alternate part numbers – or have your CEM do this for you.

Design for Manufacture — DFM essentially means considering how easy and cost-effective it is to manufacture an assembly, and designing to reduce those costs. You need a manufacturing mindset to do this well, so leave room for a DFM review and adjustments in your plans.

Thinking about contract manufacturing processes took me back to my 3 modern BOM management challenges. Bill of Material is an important key element in both – documentation and design for manufacture. Very often contract manufacturing work is focused on processes management by ERP system. However, you need to have solid PLM foundation to start thinking about CM work earlier in the process.

So, what are critical elements of PLM system to support your CM processes:

1- Access to component libraries. To have information about components, availability, cost and other parameters such as regulation is critical. To replicate this information into your PLM system is possible, but not reliable and not scalable. Check how PLM system can access this information online or federate it with ERP system you have.

2- Flexible and granular BOM management. You need to organize bill of materials in the way engineering and CM will be able to access it. By doing that you will allow early access to all parties involved into design and manufacturing to access product information.

3- Change management. Everything is changing. It will happen to your design and manufacturing plan too. Find a tool that allows you to manage traceability of changes alongside to bill of material and manufacturing plans.

4- Security. You need to have right technology in place to isolate information that belonging to different CM and subcontractors. It is important to maintain your business relationships and not to disclose sensitive information.

What is my conclusion? Globalization and cost competition leads companies to find somebody else to produce components and outsource specialized work. In many domains, CM is a way to structure industry (think about fabrication and electronic manufacturing as best examples). It leads to outsourcing, offshore and many other options to make the same work in a different places. Bill of materials (BOM) is a critical element in supporting of contract manufacturing. You need to have an ability to organize BOM in a way that allows to all involved organizations to access and make changes in the controlled way. Just my thoughts…

3D printing is changing the way we can manufacturing products. Which potentially means changes in how companies are going to manage product development processes. While it is still unclear how it may happen, I wonder if 3D printing can also change the way we manage data about product.

Forget about 3D printing as a way to make plastic covers for mobile devices and furniture for dolls. Medium article – 3D Printed Electronics Have Arrived speaks about very interesting innovation in 3D printing – Voxel8 printer capable to produce a complete electronic device as a single piece. Here is a high level explanation about printing process:

The printer uses a modular design to print both circuitry and plastic parts. One printer head extrudes PLA plastic, building the bulk of the object, while another head prints out circuitry using a very conductive ink. As the printing process goes along, the printer automatically pauses (thanks to some nifty software from Autodesk) to allow the designer to insert electrical components like motors and resistors into the print. Once the component is placed, the printer automagically resumes printing where it left off. 

What future scenario you can think about? The following passage is proposing “printing phones in store” as an option:

This printer is important because this is your future. Eventually the price for circuit-printing printers will come down, and we will see electronics shops that print phones in the store, rather than buying them from a 3rd world sweat shop. I expect that within a decade average users may even be able to customize the shape and color of their phone to their liking.

The story made me think about how a new 3D printing approach can influence the way we are managing data about products. Currently, the design is done separately for electronics and mechanical parts. Think about PCB design, electrical components and plastic body. You have data managed separate in these systems. Then you have to bring all elements of product together to create an engineering and manufacturing bill of materials. The new approach can change some fundamental principles companies are managing data today. It is hard to say how it will work, but my hunch that composed bill of material should be available at much earlier stage. It might influence the integration of design and assembly tools.

What is my conclusion? Changing paradigms. This is probably the easiest way to describe a potential change that devices like Voxel8 can bring. It can change product data management fundamentals by requiring to manage product structure differently. It can potentially change processes between engineering and manufacturing as well. Just my thoughts…

PLM and Entire System Common Data Model

by Oleg on January 5, 2015 · 0 comments

complex-system-bom

Products are getting more complex these days. There are multiple reasons for that. Adding of connectivity and software is one of the most visible reasons why it happens. Think about any simple gadget these days, which cost less than 99$ in US. It includes mechanical components, electrical parts and software. In additional to that, products are often functioning together with cloud-based or bluetoooth enabled software. The situation is even more complex when it comes to industrial equipment, transportation and other products.

Last year, I was blogging about the need to combine engineering and software BOM. My hunch, the problem is not solved yet. My attention caught by TEC Technology Evaluation writeup – 9 Innovation and Product Development Software Market Trends and Predictions made by Predrag Jakovljevic. One part of it speaks about the need to develop a holistic system common data model to manage an entire system. Here is passage, which speaks about that:

There is a need for a common data model for managing an entire system, i.e., both hardware and software data from ideation to end of life (EOL). Common repositories and software architectures must enable the reuse of design and components (and intellectual property, if you will). Thus the “innovation platform” has become a big concept for PLM-CAD-MOM players—Dassault Systèmes has the 3DEXPERIENCE Platform, Siemens PLM Software has its Smart Innovation Platform, and Autodesk’s A360, PLM 360, and Fusion 360 products all run on the same data model. Other vendors such as SAP and Oracle are not far behind. I question how many companies will be able to support an all-inclusive PLM to CAD to MES solution. My feeling is that “cloud rings or layers” with improved interoperability will emerge around PLM to reduce upgrade and total cost of ownership (TCO) costs.

The fact vendors are working on new platform can hint future modeling capabilities will help to manage more complex data structures. To create a “composite BOM model” with elements of mechanical, electrical and software parts can be an interesting PLM challenge. PLM vendors have been working on variety of BOM solutions for the last two decades. Product structure is a complex piece of data, which is representing a critical element of PLM data management foundation. Earlier days PLM complexity was related to product configurations and options. Today electronic and software is a new challenge for PLM data management.

What is conclusion? What was  a challenge for aerospace and automotive industry 20 years, now comes in electronic gadget and IoT connected devices. The ability to manage software, electronic and mechanical parts becomes a pre-requisite for any PLM system deployment. Just my thoughts…

When BOM is not BOM

December 17, 2014

Bill of Materials (BOM) is a central part of everything in product development. Sometimes, people call it product structure. Manufacturers are using BOM to define list of raw materials, parts and sub-assemblies with corresponded quantities need to manufacture a product. This is over simplistic definition. As usual, devil is details and BOM story is getting […]
