Do you think that quick turn samples are the same as pre-production test samples You couldn't be more wrong. The differences are astonishing !

Quick turn samples

Pre-production samples

Purpose: 

It is mainly used in the early stage of product research and development to quickly verify the feasibility of the circuit design and the functional principle. It helps engineers to quickly identify problems in the design, so that they can modify the design scheme in a timely manner, providing a foundation for the subsequent product development.

Purpose:

This is a sample made when the product development is basically completed and is about to enter mass production. It is used for comprehensively testing and verifying the performance, reliability of the PCB under actual production conditions, as well as its compatibility with other components, etc., to ensure that the quality of products in mass production is stable and reliable.

Production cycle and cost:

The production cycle is short, usually it can be completed within a few days or even within 24 hours. Due to the emphasis on rapid delivery, relatively common materials and simplified production processes are generally adopted, so the cost is relatively low, especially when it comes to small-batch production, the cost advantage is obvious.

Production cycle and cost:

The production cycle is relatively long. It needs to be manufactured according to processes that are closer to mass production, and it may take several weeks. Due to the need for comprehensive testing and optimization, there are higher requirements for materials and processes. Moreover, it may be necessary to produce multiple rounds for repeated testing, so the cost is relatively high.

Production process and quality: The production process is relatively simple. The emphasis is on quickly achieving circuit connections and basic functions, and the requirements for some details and precision are relatively low. In terms of quality, it can meet the needs of basic functional testing, but there may be certain defects in aspects such as appearance and consistency.

Production process and quality: The production process is closer to the mass production process, requiring strict compliance with production standards and specifications. There are high demands for the stability and repeatability of the process, as well as the consistency and reliability of the products. It is necessary to meet high-quality standards in terms of appearance, dimensional accuracy, electrical performance and other aspects.

Quantity of production:

The quantity of production is usually small, ranging from 1 to 10 pieces, mainly used for rapid verification and iteration in the research and development stage.

Quantity of production: 

The quantity of production is relatively large, generally ranging from 10 to 50 pieces or even up to 100 pieces. This is to conduct sufficient testing and statistical analysis, and comprehensively evaluate the product's performance under different conditions, providing more accurate data support for mass production.

Production process: 

Simplify the process and manufacture it quickly.

Production process:

Manufacture strictly in accordance with the mass production process.

Testing scope:

Preliminary functional testing

Testing scope:

Comprehensive testing (electrical, reliability and environmental aspects)

Material selection:

Give priority to manufacturing according to the materials required by the customer. If there is insufficient material stock, in order to ensure rapid delivery, communication will be carried out with the customer to find materials with similar performance for replacement.

Material selection:

It is necessary to manufacture completely in accordance with the materials required by the customer. If there is insufficient reserved materials or the required materials are not available in stock, new procurement must be carried out even at the customer's expense. Ensure that all materials are completely consistent with the customer's expectations.

Engineering cost:

Due to the small production quantity, engineering costs (such as material cutting, programming, testing, etc.) will be allocated to each single board, resulting in a relatively high unit price.

Engineering cost: 

The pre-production samples are usually the last verification before mass production. The production quantity is likely to be larger than that of the prototypes, and the engineering costs can be spread across more pcb circuit boards.

Engineering document processing:

High flexibility of documents: 

In the stage of rapid prototypes, the design may not be fully finalized yet, allowing for a certain degree of flexibility and room for modification.

Rapid processing: 

When dealing with engineering documents, speed is given priority. Some detailed verification steps before mass production (such as DFM analysis) may be skipped.

Simplified process: 

A simplified technological process may be adopted to reduce time and cost.

Engineering document processing:

High rigor of documents: 

The engineering documents for pre-production samples are usually the final version and must undergo strict DFM (Design for Manufacturability) analysis.

Comprehensive verification:

The processing of engineering documents will include complete process verification, development of testing procedures, etc., to ensure consistency with mass production conditions.

Standardized process: 

The same process flow and equipment as those used in mass production are adopted to ensure that the results of the samples can truly reflect the performance during mass production.
