Rapid PCB prototyping facilitates bringing products to market faster. However, balancing expedited delivery against budget constraints when selecting your quick turn manufacturer is vital.

This guide examines quick turn PCB capabilities, the merits of fast prototyping, key manufacturer selection criteria, how to keep costs low, and the must-have services to enable accelerated board builds.

What are Quick Turn PCB Capabilities

Quick turn PCB manufacturers offer expedited fabrication of custom designed bare printed circuit boards on extremely short notice.

Typical lead times for quick turn services are:

Lead Time	Description
24 Hours	Simple, 2-layer boards
3-5 Days	Moderate complexity
5-10 Days	High complexity boards

Capabilities span simple single-sided boards to advanced multilayer boards supporting the latest high density interconnect (HDI) and substrate technologies.

However, managing costs with quick turn services can prove challenging. We cover techniques for keeping expenses lower later in this guide.

First, let’s examine why fast prototyping is so valuable.

The Value of Fast PCB Prototyping

For hardware developers, lengthy traditional PCB fabrication cycles slowing product development momentum. Rapid prototyping solves this.

Benefits of fast PCB prototyping include:

Balancing Low Cost with Quick Turn PCBs

With rapid prototyping’s inherent compressed schedules, controlling expenses can prove tricky. Here are tips to lower costs:

Leverage Standard Offerings

Opt for their templated design rules, materials, processes, and testing which maximize manufacturing efficiency over customized services.

Scale Economically

When migrating from prototyping to pilot build volumes, leverage bulk order discounts available at higher monthly quantities.

Consolidate Orders

Where feasible, consolidate multiple board designs into the same quick turn production batch to maximize panel utilization rates given fixed setup costs.

Reuse Earlier Test Fixtures

For downstream design iterations, repurpose prior test fixtures again instead of paying to develop new ones.

Negotiate for Discounts

If working with an emerging provider lacking brand recognition, negotiate for preferential pricing in exchange for public testimonials on their services.

Consider Production Offshore

Transitioning later stage production offshore could yield cost savings on labor, facilities, regulatory costs, and volume material pricing. Weigh total landed costs.
