Importance of Design for Manufacturability (DFM)

It is an old saying that “Design for Manufacturability” is a design philosophy aimed at making your PCB easy and cheap for manufacturing. Applying DFM principles would mean keeping different parts to a minimum, not using those types of components that can give rise to difficulties in soldering, and keeping an adequate zone around each component for assembly equipment.

DFM can reduce assembly time significantly. As a result, it is ideal for applications that require a quick turnaround.

Recommendations for Component Selection and Placement

  • Selection of Components: Use only basic, common components to avoid procurement/lead-time issues; also, consider using components which automatic placement machines can easily handle.
  • Position Strategy: The components should be placed so that they do not require a lot of repetitive manual soldering. Never place through-hole components too close to the surface-mounted components to allow easy access for the machine.

Preparing Comprehensive and Clear Documentation

The first and most important step toward the success of the quick-turn PCB assembly process is clear documentation. This shall assure you that your assembly partner understands your project requirements properly, and hence, there shall be a reduction in any unnecessary correspondence and possible errors.

  • Essentials of the Bill of Materials (BOM): Your bill of materials (BOM) has to be complete and fully descriptive, including manufacturer part numbers, descriptions, and quantities, even indicated for acceptable substitutes. This will enable quick procurement and availability of the components for your design.
  • Assembly Drawings and Instructions: Provide clear assembly drawings that illustrate the location and orientation of each part. Include any special instructions or considerations in your project, such as applying heat sinks manually or placing wiring by hand.

Applying these practices will make your PCB designs much more assembly-friendly and, in the end, greatly improve the efficiency of the quick turn PCB assembly process.

Such a complete preparation not only speeds up the assembly process but also contributes to the quality and reliability of the finished product.

Remember that your goal is to smooth out every aspect of the assembly, from design to documentation, so that your project smoothly transitions efficiently and quickly from concept to completion.
