Introduction

For hardware engineers and startups, the ability to quickly fabricate printed circuit boards is imperative to accelerate prototyping and product development. Partnering with a PCB fabrication service capable of delivering boards in 3-5 days enables faster design validation and testing. This guide covers how to select the right quick turn PCB fabrication partner.

Capability Range

Evaluate if the potential partner’s capabilities meet your needs:

Layer Count

LayersComplexity
2-8 layersSuitable for simpler, low-mid complexity boards
10-20 layersNeeded for more complex designs
20+ layersExtremely high complexity boards

Choose a shop able to produce the layer counts required now and in the future.

Line Width/Space

The smaller the trace width and spacing, the higher the circuit density possible.

Line/SpaceDescription
6 milOnly useful for simple boards
4 milAllows moderately high density
2 mil or lessNeeded for advanced boards

Solder Mask Type

LPI (liquid photoimageable) solder mask offers superior durability, resolution and aesthetics compared to dry film types.

Advanced Materials

Quick turn shops should offer material options beyond standard FR-4 like Rogers, Arlon, polyimide etc.

Quality Processes

Quality must not be sacrificed for faster delivery. Look for:

  • IPC Certification – IPC-6012 and IPC-A-610 certification indicates adherence to industry standards.
  • Testing – Electrical, flying probe, and boundary scan testing to validate fabricated boards.
  • AOI Inspection – Automated optical inspection to identify defects human inspectors could miss.
  • Engineering Review – Analysis by engineers prior to fabrication to resolve any issues in the design data.
  • First Pass Yield – Percentage of boards passing testing the first time indicates consistency.
  • Test Coupons – Inclusion of test points on panelized boards enables quality measurement.

Value-Added Services

The best quick turn PCB fabrication partners offer services like:

Assembly

Component population services for printed boards including:

  • SMT Assembly – Populating PCBs with surface mount components
  • Thru-hole Assembly – Manual soldering of leaded components
  • Complete Box Build – Multi-board assemblies and cabling

DFM Analysis

Reviewing designs prior to fabrication for manufacturability and providing optimization feedback.

Testing Services

Assistance with test fixture design, test plan development, and performing functional testing on populated boards.

Supply Chain Management

Sourcing and procuring required components for SMT assembly and kitting services.

Location Proximity

For the fastest turnaround, use a PCB fabrication service located in your region:

  • North America for companies in USA and Canada
  • Europe for companies in EU region
  • Asia for companies located in APAC region

This avoids long shipping times from boards fabricated overseas.

Lead Time Capability

Look for partners offering:

  • Standard lead times of 3-5 days
  • 2-3 day expedited services
  • 24-48 hour rush services for urgently needed boards

Avoid shops with lead times exceeding 7 days.

Summary

Partnering with the right quick turn PCB fabrication service enables validating designs in less than a week. When selecting among potential partners, prioritize quality, capabilities, value-added services, and fast delivery. Investing effort to qualify suppliers will accelerate future prototyping and product development.
