Frequently Asked Questions
What is considered "quick turn" for PCB assembly?
Quick turn PCB assembly typically refers to services delivering finished assemblies in 10 days or less, though the specific definition varies by provider. Many services offer multiple tiers: emergency (24-48 hours), express (3-5 days), and standard quick turn (5-10 days). The actual turnaround depends on design complexity, component availability, and order volume. Standard production usually takes 2-4 weeks or longer, so any service significantly faster than this qualifies as quick turn. It's important to clarify whether the stated turnaround begins when files are approved or when all components are available, as this significantly impacts the actual timeline.
How much more does quick turn assembly cost compared to standard turnaround?
Quick turn PCB assembly typically costs 25-150% more than standard turnaround times, depending on how expedited the service is. Emergency 24-48 hour service commands the highest premiums (100-150% over standard), while 5-10 day quick turn might add only 25-50% to the base cost. The premium covers expedited component procurement, priority placement in production queues, overtime labor, and accelerated quality testing. However, for time-critical projects, this premium often represents excellent value when considering the opportunity cost of delays. Some providers offer bundled pricing that includes the expedite fee, while others charge it separately, so comparing quotes requires careful attention to what's included.
Can quick turn services handle complex, high-layer-count boards?
Yes, many professional quick turn PCB assembly services can handle complex designs including high-layer-count boards (10+ layers), though turnaround times may be longer than for simple designs. The key factors are component availability and testing requirements rather than board complexity alone. However, not all quick turn providers offer the same capabilities—some specialize in simple prototypes while others maintain equipment and expertise for advanced designs. When evaluating providers for complex boards, verify their experience with your specific requirements (HDI, rigid-flex, controlled impedance, etc.) and ask about typical turnaround times for similar complexity projects. Complex designs may also require more extensive DFM review time before production begins.
Should I use the same provider for prototypes and production?
Using the same provider for both prototypes and production offers significant advantages: they're already familiar with your design, have established component sourcing relationships, understand your quality requirements, and can maintain consistency between prototype and production. This continuity reduces risks during scaling and simplifies communication. However, some companies specialize exclusively in quick turn prototyping and may not be cost-competitive for higher volumes, while production-focused manufacturers might not offer truly fast prototype turnarounds. The ideal approach is finding a provider offering competitive both quick turn prototype services and scalable production capabilities, or at minimum ensuring your prototype provider can easily transfer designs to your production partner.
What information do I need to provide for an accurate quick turn quote?
For an accurate quick turn PCB assembly quote, provide: complete Gerber files for your PCB design, a detailed bill of materials (BOM) with manufacturer part numbers and quantities, assembly drawings showing component placement and orientation, your desired turnaround timeline, and quantity needed. Additional helpful information includes special requirements like conformal coating or potting, testing specifications (AOI, X-ray, functional testing), shipping destination and urgency, and whether components will be customer-supplied or provider-procured. The more complete and clear your initial submission, the faster and more accurate the quote will be. Many providers offer online quoting systems that can provide instant ballpark estimates, with detailed engineering quotes following review of your specific design files.
Conclusion
Selecting the right quick turn PCB assembly service is a critical decision that impacts project timelines, costs, and ultimate product success. The ideal provider combines technical capabilities matching your requirements, robust quality systems ensuring reliability, reasonable turnaround times balancing speed with realism, transparent and fair pricing structures, excellent communication and support, and relevant industry experience.
