What is a Quick Turn PCB Assembly?

Printed Circuit Boards have vast applications in consumer electronics, telecommunications, and automotive sectors. There are thousands of PCB manufacturers in China greatly driven by the emergence of information technology, automotive electronics, and the Internet of Things.

PCB assembly is the process of mounting electronic components into the PCB circuit boards. With the surge in demand for PCBs, more and more customers are seeking manufacturers with fast turnaround times. This type of assembly processing, also known as “Quick Turn PCB Assembly”, can shorten the lead time from weeks to just 24 hours, depending on the agreed design.

Quick turn PCB assembly means printed circuit boards are assembled in a relatively short time. The average processing time of a standard PCB can take up to a week or more which heavily relies on the complexity of the design. As for quick turn PCB assembly, China quick turn PCB assembly manufacturers take the leading position in both quantity and quality.

Below are the factors that can substantially affect the processing durations: number of layers, PCB thickness, design complexity, number of components and order quantity. Quick turn PCB assembly is often adopted in prototyping or mid-volume quick-turn PCB assembly wherein a tight deadline for the project is required.

PCB assembly that meets the customer’s fast delivery requirements is called quick-turn PCB assembly, or fast turn PCB assembly.

    What are the Benefits of Quick Turn PCB Assembly?​

    Let’s next examine the benefits of quick turn PCB assembly services. The reasons why most customers would opt for quick turn PCB assembly are the following:

    • Time-Saving: As the famous Benjamin Franklin’s quote goes, “‘Time is money.”, which implies that with time, money can be indirectly generated. In the context of quick turn PCB assembly services, the shorter the time is, the earlier the product can be used which translates to higher customer satisfaction, and more units that can be produced within a particular time span.
    •  Cost Avoidance: Since production times are shortened, spending is also lessened. 
    • Customization: Since the goal is to shorten the production time, materials, components and processes can be optimized without sacrificing the quality and overall functionality of the boards.

    What are the Common Challenges in Quick Turn PCB Assembly?

    Challenges are unavoidable in any business decision. As we are trying to squeeze the turnaround times, we must be aware of the challenges that may come along the way. In this manner, mitigation actions and careful planning must be done to overcome the challenges:

    Component Availability

    With the rising number of China quick turn PCB assembly manufacturers, components may not be easily available for purchase. Remember that the Bill of Materials (BOM) for PCBA is composed of several components, both active and passive components, so it is necessary to make sure that everything is available to avoid unwanted surprises during project execution. 

    There are several approaches to solving this problem. The first is to build and maintain relationships with suppliers. This will help to ease sourcing of the needed parts as you have a list of alternative options for suppliers and have accessible means to communicate with them. Another solution is to establish a stock system to ensure the availability of component inventory. For the parts that have high demand, especially the passive components, it is best to have buffer stock to eliminate shortages and project delays due to material sourcing and lead time. An important method is also to find an alternative part that has the same fit, form and function for flexible options. In case the designated part is not available, you can still purchase the alternative component and meet your timeline. 

    Time Constraint

    Since the primary goal for China quick turn PCB assembly is to be able to manufacture the boards in a short time frame, every detail and activity should be laid out. The timeline is often plotted in a "Gantt Chart" which shows the breakdown of activities and the planned timing of completion. Part of the timing is also the expedited delivery as the printed circuit board needs to arrive to the customer on time. 

    Cost Control

    Knowing the allocation of budget in your printed circuit board project is one of the main challenges of quick turn PCB assembly. Making several design iterations and redoing PCB prototypes can bulk up the cost. Other factors affecting mid-volume quick turn PCB assembly services are the cost of materials, complexity of the processes and testing.

    Quality Error and Defects

    Getting to the final product within a prescribed time can sometimes push aside other critical metrics like quality and good parts yield. This is where thorough Design for Manufacturing analysis and assessment plays a vital role. During the design development of the printed circuit board, the schematics and layout must be evaluated for tolerances, robustness, and functionality. The design team should have constant coordination with the manufacturing team for any potential concerns during manufacturing.

    What are the Factors to Consider in Choosing a Quick Turn PCB Assembly Manufacturer?

    Many companies are also offering quick turn PCB assembly services with highly automated processes and expert engineering support. Quick turn PCB assembly makes these companies more competitive due to an added advantage in terms of time to deliver the products. Do not trust easily in choosing a China quick turn PCB assembly supplier. With the primary intent to speed up production, keep in mind that a suitable supplier is very critical in ensuring that your main and secondary objectives are met.

    Delivery Time

    Delivery time should be as short as possible which can be achieved by having a short manufacturing cycle and expedited shipment to be able to complete a printed circuit board delivery. The committed delivery time must also have a detailed cycle time for each process to be able to plan correctly. Quick turn PCB assembly does not end when the finished goods are produced. The success rate will depend on how fast the part has been delivered to the customer. Design to manufacturing can be done in as short as seven days. Company websites often publish their quick-turn PCB assembly delivery time based on the number of layers. 


    Even with the fast turnaround times, quality must be given high importance and priority. To determine if the China quick turn PCB supplier can be qualified, there are several international standards that should be complied too. A common standard that is known to almost all industries is ISO certification which has sets of requirements related to quality management systems. Even with quick turn PCB assembly, the components, and materials to be used must still conform to IPC and UL standards which are both international organizations which cater to the electronics manufacturing industry.

    Technical Capabilities

    Quick turn PCB assembly cannot be realized if the machines to be used are slow, manual, and difficult to set up. A quick turn PCB assembly manufacturer should have state-of-the-art, highly automated machines that can cater to complex printed circuit board designs with varying component types. Technical capability in terms of design and manufacturing engineering support is also essential. A good and capable quick turn PCB assembly supplier can offer a prototype quick turn facility and a high-volume production factory with low-cost labor. In this type of business model, processes are optimized and a smooth transition to high-volume manufacturing is possible since communications are more streamlined from design to production. Advanced Surface Mount Technology (SMT) line must be available with capabilities that match your technical requirements. 

    Customer Service

    Come to think of it, poor customer service usually impedes smooth communication and further delays decision-making during product development and manufacturing. If there are requirements that are misunderstood, the cycle time can be severely affected. The customer, design team, fabrication and engineering support team must all work closely together to discuss issues and project status. Excellent customer service means being able to address concerns in a timely manner, being proactive to potential concerns and being transparent with the gaps and issues to correct and prevent problems. Technical and administrative support must be provided by the supplier to strike a balance between meeting the shipment requirements and having a quality and fully functional PCB. 

    PCB Assembly Cost

    Cost, almost needless to say, is a common metric in choosing a suitable partner for quick turn PCB assembly services. Better select a China quick turn PCB assembly supplier that can meet your desired project deadline and still offer competitive pricing. Suppliers can be dealt with in terms of how cost can be reduced by choosing an alternative, cheaper material or eliminating unnecessary or non-value-adding processes. A detailed quotation must be requested with the breakdown of each cost factory for easier assessment of how to make the project more cost-effective.

    What are the Steps in Quick Turn PCB Assembly?

    To ensure high quality and quick delivery, we alway follow the steps in quick turn PCB assembly, from DFM to prototyping, pre-production, full production,  testing and inspections. Please refer to the detailed steps as below.

    Step 1: Design for Manufacturability (DFM) Check

    The PCB design must first be submitted to the quick turn PCB assembly manufacturer and will undergo a Design for Manufacturability (DFM) check. The design is in Gerber file format which is the industry-known standard used for manufacturing. Gerber files are often one of the main references of quick turn PCB suppliers for pricing. 

    The DFM review is a process of technical verification if the materials and design conform to IPC standards and capabilities of the manufacturing or assembly line. In DFM, brainstorming is being done by the design and assembly team to assess risks and ensure that the quick turnaround is met by eliminating potential errors. 

    Step 2: Prototyping

    Prototyping is first performed to have some initial builds to evaluate the functionality of the printed circuit boards. A series of collaborative discussions between the manufacturer and project leader are being conducted to know the gaps and potential improvements in the design. For high volume quick turn PCB assembly services, this often happens in a very short period. Prototyping is an important stage where correction and revisions can be done to have a robust quick turn production.

    Step 3: Pre-production

    The next stage is pre-production wherein a few quantities are again produced to test in a relatively bigger volume and check the readiness of fabrication and assembly line. 

    Step 4: Full Production

    The next phase is full production PCBs wherein the design and assembly technologies are already frozen and satisfy the requirements for mass production.  

    Step 5: Inspection and Testing 

    Finally, inspection and testing should be done as part of the quality checks of the product. Even if it is a quick turn PCB assembly, these quality checks are significant to filter out only good units that are then to be shipped to customers. Inspection includes rapid Automatic Optical Inspection (AOI) machines which check for the solder joints and completeness of components on the printed circuit boards. Testing is also being done through In-Circuit Testing or Flying Probe Testing which are both test probe methods that check for electrical connection issues. The main difference is that in-circuit testing utilizes a fixture while a Flying Probe Test has movable probes that can access test pads.


    High volume quick turn PCB assembly has gained popularity due to the rising demand for electronic products. Options are available left and right for PCB assembly providers that can cater to your needs and time requirements.
