What is a Quick-Turn PCB?

A quick-turn PCB is a circuit board designed, fabricated, assembled, and tested in hastened processes that take short periods. Depending on the design complexities, this production time can vary from 24 hours to seven days.

Production Stages for Quick Turn PCBs

Quick-turn boards undergo three production stages.

Prototype Stage

Manufacturing a prototype PCB incorporates all the vague requirements and details required to reduce the delivery time and manufacturing costs. Additionally, the PCB prototype allows users to test how the finished product will work. It enables clients to make the required changes while manufacturers can check for faults to enhance performance and efficiency.

So, this stage captures the corrections, omissions, rectifications, additions, and subtractions to ensure the production PCB has zero technical or mechanical shortcomings.

Beta Run/Pre-Production

A beta run involves building quick-turn boards in batches of hundreds to several thousand pieces. It is one of the most vital phases in the process because these PCB templates usually translate to the final product. So the manufacturer must eliminate all mistakes in this stage.

The process entails conducting electrical tests, optimizing the board layout, checking tooling arrangements, avoiding pitfalls, etc.

Full Production

The final production stage is quick-turn PCB manufacturing for market applications. Orders in this phase are higher and better than in the other steps but can take longer.

Quick-turn PCB fabrication can only reach this stage once the design and engineering team has gone through the previous phases to fine-tune everything and build high-quality boards.

Key Features of Quick-Turn PCB Prototypes

The primary feature of quick-turn PCB prototypes is their speedy production. These boards are meant for projects requiring quick development, especially if you want to beat the competition.

These PCB prototypes are also highly flexible because you can reconfigure them quickly if they need adjustments.

Although ideal for designing small quantities of circuit boards, this prototyping method reduces production time significantly and provides a broader window for making adjustments and fine-tuning the board before mass production.

The fine-tuning also ensures there are zero manufacturing delays by minimizing production changes.

As a result, you’ll enjoy a longer period of getting your ROI before having to adjust or upgrade the board because it will end up being almost perfect when customers buy your product.

Quick-Turn PCB Prototyping Process

This prototyping process begins immediately after the design and begins with the design files.

Design File and Specification Review

The designer sends the centroid and Gerber files, the bill of materials and other prototyping documents to the manufacturer to commence production.

DFM Check

On receiving the required design documents, the manufacturer performs a design for manufacturability test before material selection. This process ensures the fab house can effectively manufacture the board and eliminates any production issues that can cause setbacks or delays.

Material Selection and Inventory Check

The manufacturer then checks if all the materials are available in the inventory, including the substrates and the electronic components required for assembly.

Prototype Fabrication and Assembly

Production begins once everything is in place and proceeds rapidly, followed by component assembly.

Quality Control

The complete quick-turn prototype circuit board undergoes inspection and testing for quality control to ensure the customer gets a high-quality working product.

Fast Turn PCB Assembly

This assembly process involves producing complete boards rapidly in as little as 24 hours but can go up to five days if you want a batch of circuit boards. Fast-turn assembly enables tech companies to build proof of concept under short deadlines to hasten product development and time to market.

The assembled batch is usually small, 10-100 orders, and includes double-layer or multilayer boards with surface mount or through-hole components.

Factors Affecting the Turnaround Time of a PCB

The time to market for quick-turn PCBs depends on several factors, such as the following.

Design and Test Procedures

Adhering to the DFM and DFT guidelines enables faster completion times, plus high-quality boards. Also, check the availability of components before including them in your design and determine the best layout strategies for compact designs. Lastly, establish clear test protocols and requirements in advance for a quick turnaround time.

Lamination Cycles

A High-Density Interconnect (HDI) board with multiple via structures requires sequential lamination cycles, a task resembling fabricating multi-layer boards. This board type increases manufacturing time, cost, and complexity.

The time required for each lamination cycle depends on the board layer count in the stack-up and the material used. Each separate layer adds an average of 4-5 days to the production process, which includes the drilling, filling, and plating time. And board manufacturers require at least one extra day for outer layer processing.

Via-in-Pad Plated Over

Via-in-pads have become typical in most PCBs because they can keep heat from the component's lower section or save space. However, incorporating them can add at least one extra day to the cycle time.

Fabrication Drawing Specifications

A fabrication drawing indicates vital manufacturing data, such as the following.

  • IPC class
  • Mechanical dimensions
  • Via drill chart
  • Layer stack up
  • Plating thickness

So, you need to know the PCB manufacturer's capabilities to close the gap between the design document and the DFM to reduce or avoid rework time delays. And always mention if the prototype follows IPC class 2 or 3 manufacturing standards.

Similarly, carry out multi-layer PCB stack-ups while considering material cost and availability. Rare materials will require more time to source, increasing the turnaround time. While at it, verify the drawing's controlled-impedance table to ensure it identifies the trace width and target impedances that require controlling to avoid delays caused by mismatched information.

Surface Finish

Surface finishing is also time-consuming because each coating requires a specific completion time. For instance, ENIG takes 1.5-2 hours to complete, while HASL only requires 15-20 minutes at most.

So, it will take more time to complete a high-quality PCB with two finishes, such as ENIG for the surface-mount connectors and hard gold for the edge connectors. Each finish gets applied separately, and the time will add up.

Assembly Drawings and Fabrication Notes

Fabrication notes and assembly drawings assist in circuit board inspection because they contain the parts list, bottom and top views, shapes, etc. Consider the following points to prevent delays during the board assembly process.

  • Adhere to the DFA guidelines while confirming zero component footprint mismatches.
  • Follow kitting guidelines if supplying parts
  • Ensure silkscreen feature markings remain visible
  • Send a complete BOM that includes the manufacturer part numbers and product descriptions.

Benefits of Quick Turn PCB Manufacturing

Quick-turn PCBs are better than traditional PCBs because of the following advantages.

Time Savings

Customers can leverage the time savings in the manufacturing process of these boards to gain a competitive advantage in the market by launching products faster. Additionally, quick-turn PCB fabrication encourages innovation and quick execution, enabling you to translate new ideas to the market in a short time.

Cost Savings

The process assists the DFM, resulting in a significant reduction in production costs. The fabrication stages also utilize cost-effective materials and components, reducing costs.

Board Variety

Manufacturers usually provide multiple PCBs in their selection to meet the requirements of different users.
