DFM Tips
Our top Design For Manufacturing tips for engineers and technologists.
- Designing to Reduce Inventory Costs
Inventory control represents one of the highest cost areas in the manufacturing supply chain. Whether you are outsourcing the complete supply chain and manufacturing of your product in a turnkey model or using a consignment model, a number of design considerations can help to reduce the hard costs, overhead, and risk of inventory.
This DFM tip provides some best-design-practices for reducing inventory risk and cost.
- Planning Your Test Strategy
While testing is one of the last steps in the manufacturing process, it must be planned for early – as part of the design process – in order to ensure that necessary tests can be carried out and that they can be done so cost-effectively.
This DFM tip provides best practices for planning the test strategy for your electronics device.
- Best Practices for Preparing Documentation
As a contract electronics manufacturer, OCM Manufacturing relies on documentation provided by our clients to understand the services we need to perform. Documentation includes files such as design schematics, assembly drawings, test procedures, bills of materials and more. Problems or omissions in this documentation result in delays and, in extreme cases, may lead to product deficiencies and quality issues. The following best practices will help to ensure that the documentation you send to your contract manufacturer is in good order.
- Best Practices for Surface Mount Technology (SMT) Design
Increasingly fine-pitch devices and increasing levels of automation are resulting in greater density in board design than ever before.
This tip provides best practices that will help ensure that an SMT device is manufacturable.
- Best Practices for Double-Sided Mixed-Technology Board Design
Although Pin Through Hole (PTH) designs are being phased out in favor of Surface Mount Technology (SMT, many designs still mix PTH and SMT. PTH also remains in use for some heavy power connectors, transformers, and other devices where strong mechanical bonds are required.
This tip outlines some key best practices for double-sided, mixed-technology design.
- Optimizing Board Design for Adequate Clamping Space
Two common oversights related to board design affect whether the manufacturing equipment can effectively process a board. Whether your board is manufactured using pin through hole (PTH) or surface mount technology (SMT), the manufacturing equipment requires certain space on the board for clamping, transport, and/or supporting its weight. This tip provides rules of thumb for meeting these requirements while still optimizing board space.
