How Long Does Manufacturing Prototype Assembly Take?

Manufacturing Prototype Assembly

The speed and accuracy with which hardware designers turn prototype designs into fully functioning devices is key to getting new products to market sooner. The right ECM partner enables fast turnarounds that allow design iterations to be fabricated quickly, while ensuring quality and seamless transition to production. Experienced electronic component manufacturers (ECMs) have robust capabilities that help startups and design houses accelerate product development schedules while avoiding costly delays that can result from a poor choice of ECM.

The typical lead time for prototyping varies widely, but there are some simple ways to get the most out of your time and budget. For example, partnering with an assembler that offers DFM analysis, BOM review, and engineering support services ensures you receive the highest quality product while minimizing costly delays.

During the prototype stage, you should also limit your board size and complexity to minimize fabrication and assembly time. You can further reduce the assembly timeline by ensuring your design is optimized for prototyping through proper PCB layout, component selection, and design-for-manufacture guidance from your assembler.

Another way to cut down on assembly times is by selecting a standard material like FR-4 that can be quickly sourced and assembled with minimal engineering work. This saves you from the wait associated with specialized or exotic materials that may require a longer lead time for procurement.

It is also important to communicate your expected delivery dates clearly with your assembler and provide detailed test requirements up front. This helps the assembler determine if there are any potential issues with the design, which could potentially delay production and/or impact yields. The assembler can also use this information to prioritize sourcing and assembly steps in order to achieve your deadline.

When choosing a rapid prototype assembly, make sure they can meet your timeline requirements through a careful evaluation of their technical capabilities, assembly equipment and capacities, and client case studies. You should also ask about their pricing models. Some charge a premium for rapid prototyping, while others include it in their base price. Additionally, look for a domestic assembler to reduce shipping costs and expedited processing times.

Finally, be sure to factor in additional processing and quality assurance time for any rework or repairs. A good rapid prototyping assembler will be flexible, responsive, and follow rigorous assembly and inspection protocols to avoid any unforeseen issues or delays. You should also be sure to ask your assembler about their adherence to PCB design, fabrication, and assembly guidelines (IPC is ideal). Finally, you should be sure that they are able to accommodate rush orders with a clear communication of cost drivers and expected turnaround.

The decision to repair a prototype also depends on the purpose of the prototype. If the prototype is being used for functional testing, ensuring that it operates correctly is paramount. In such cases, repair is often essential to continue testing without interruption. However, if the prototype is primarily for visual or ergonomic assessment, superficial repairs might suffice to restore its appearance without needing full functional capability.
