Quick-Turn PCB Prototyping Service

Hi friends, I hope you are enjoying yourself a lot and having a great deal of fun. Our mission is to help you by providing quality content that meets your expectations so now today we will discuss all quick turn PCB prototyping services. We will discuss what is quick-turn PCB? What is a PCB prototype? What is a quick-turn PCB prototyping service? Quick turn PCB general Capabilities provided by companies. Benefits, applications and importance of quick turn prototyping service. Online Quick-turn PCB service providers and time measurements. So, let's get started:

Overview

• First of all, before starting the discussion we have to know about the meanings of the words used in our topic heading.
• We have to make grip on the meanings of quick turn, PCB, prototype, and service. After understanding the heading of the topic we will be able to understand core concepts.
• Quick turn: quick turn means something or someone that does things with great speed. Day traders use the quick turn technique to make a great deal of profit.
• PCB: PCB stands for the printed circuit board. It is a combination of conductive and insulating layers to perform specific functions that meet the demands of customers.

• The prototype is defined as an original model on which something is patterned. It is an early sample product built to test a process or concept.
• Now prototyping is a fundamental process for designing a new product on which electrical components will be patterned.

• Service: service is a system that is used to provide utilities like providing PCBs to the provided/desired location.

What is a quick turn PCB?

• Now after understanding the meaning of each term used in the heading we have to understand what is quick turn PCB? What is PCB prototyping and then we will discuss what is quick turn PCB prototyping service?

• A quick turn PCB means that a customer has their PCB faster than ever before.
• A quick turn ensures that a customer doesn’t have to wait for their product so it reduces delays.
• A quick turn also ensures that the manufacturing time for the PCB is reduced.

What is PCB prototyping?

• A PCB prototyping is to help designers to determine if there are any faults in the original PCB.

• It helps to improve performance and enhance efficiency.
• As prototypes are crucial so it is very difficult to make changes in the PCB which is manufactured.
• Quick turn PCB prototyping service means that providing PCB prototypes to the customers at a very fast speed, without delay.

Online Quick turn PCB prototyping service providers:

There are some online quick turn PCB prototyping service providers available. The one I am going to recommend is JLCPCB Fabrication House. JLCPCB provides this service of Quick-Turn PCB Prototyping for researchers so that they could test their projects in no time. Here are a few of the key points of this service provided by JLCPCB:

Quick turn PCB service types:

PCB manufacturing service providers provide PCB quick turn services as

• 1-day quick turn PCB prototype
• 2 days quick turn PCB prototype
• 3 days quick turn PCB prototype
• 5 days quick turn PCB prototype
• 10 days PCB standard PCB prototype
• > 10 days PCB prototype.

Benefits of quick turn PCB prototyping service:

• Why do designers rely on prototypes instead of making a standard product? The answer to this question is that the prototype allows designers to test the functionality of the product in the design process at several stages and allow them to make adjustments according to their needs.
• Prototyping creates several advantages for customers and manufacturers as

1. Reduced timeline:

PCB prototypes help designers to complete their final product in these ways by saving their time.

• PCB prototypes complete the testing process at a fast rate. Without prototypes, flaws will waste a lot of time, lost revenue, and make a customer unhappy.
• PCB prototypes also save time by providing visual assistance to clients during the production process.
• At several stages, Prototypes help in testing before a full production run and save not only time but also minimized rework.

2. Reduced costs:

Prototypes help in reducing cost by avoiding the following issues:

• Catching design flaws
• Pinpointing cost-saving adjustments.
• Determining product adjustments.

3. Test components individually:

Designers use PCB prototypes for testing purposes. Most beneficial testing is achieved by testing simple PCBs. This type of testing is used to achieve the purposes listed below

• Testing design theories
• Breaking down complex designs.

4. Accurate reliable prototype:

Accurately designed reliable prototypes help throughout the designing and manufacturing process. Quality PCB prototypes allow designers to test the following aspects:

• PCB design
• Functional testing
• Conditional testing
• Final product design

5. Manufacturing review and assistance:

Using third party PCB prototyping services companies gain benefits but several things can go wrong in the design process that results in mistakes listed below:

• Excessive input
• Design blind spots
• Design rule check

Applications of quick turn PCB prototype:

Quick turn PCB has several applications in different industries. The applications in different scenarios are listed below:

1. Electronic designers who require high-quality boards use quick-turn PCB prototypes.

2. PCB assembly manufacturers designs products for the mass market use quick turn PCB prototypes to fulfil the needs of the market. 3. Designers also need to work on new ideas so they use quick turn PCB prototypes. 4. To provide the investors and clients the samples of their products designers need to show quick turn PCB prototypes.

Importance of quick turn PCB prototyping service:

• The role of PCBs in the best performance of electronic devices can not be denied.
• Electronic devises based companies heavily depend upon PCB prototyping firms and their efficiency of fabrication.
• However, to meet challenging deadlines, pressing schedules, and excellent quality PCB manufacturing, quick turn PCB prototyping service plays a crucial role.
• Let’s know-how companies benefit from their quick services and attain their business goals.

1. By providing quick turn services, companies increase their number of customers.
2. For the projects that need to be completed in a very short time, companies charge extra amounts. To attain the goals of extra profit, and everything related to PCB manufacturing should be perfect.
3. By providing reference prototyping services, companies built a trust relationship with their customers.

• Listed above are the benefits/ importance for companies providing quick turn PCB prototyping service. Quick turn PCB prototyping service is not only beneficial for companies but also for clients. Here is the importance of quick turn PCB service for customers.

1. By obtaining their prototype according to their demands, customers can complete their projects on time.
2. Customers do not have to waste their time in transportation and searching for PCB, they just have to order PCB and mention their requirements. Their desired PCB will be at their door.
3. There are also some cost benefits to customers in this service.

Quick turn PCB prototyping service time measurement:

• When an order is placed in the morning like at 9:00 am then at next business day noon, 1 day is completed and from noon after 24 hours, 2nd day is completed from your order.
• If an order is placed at 12:00 am then after 24 hours, 1 day will be completed. And next days will be counted similarly.
• For orders placed after 4:00 pm lost much of their time so placing late time orders is not suitable.

Conclusion:

When we think about PCB prototyping, it seems an additional step that will enhance the PCB cost and we consider it one that never is overlooked. But the reality is that it is best to weed out errors, flaws, and faults before proceeding to the final product. Prototyping helps in reducing cost, provides us with quicker turnaround time, and provides you with more efficient design. Now designers always prefer prototypes before developing new innovative ideas as well. They know about the value of time, cost and quality so suggest to students, engineers, and innovators to use prototypes. In the end, we can say that the value of PCB prototypes can not be neglected, they are as fruitful and helpful as standard PCBs.
