PCB Prototype Manufacturing Solutions
PCB prototypes are the first samples of a product that are built to test the functionality of the design ideas. Designers and engineers test various aspects of a chosen design using various types of PCB prototypes. The primary goal of creating a PCB prototype is to ensure that the circuit works as intended and to identify and resolve any issues before mass-producing the final PCB design.

Testing Procedures
A PCB prototype is a pre-production version of a printed circuit board that is used to test and verify a circuit’s design before it is mass-produced. Prototyping is an important step in the PCB design process because it allows designers to identify and correct any issues with the circuit’s layout or functionality before it is finalized.
There are several different ways to create a PCB prototype, including:
- Using a prototyping board: A prototyping board, also known as a breadboard, is a type of PCB with a grid of holes that allows you to easily connect electronic components using jumper wires. This is a quick and simple way to test a circuit, but it is not suitable for permanent use as the connections are prone to coming loose.
- Using a PCB fabrication service: Another option is to use a PCB fabrication service to create a small batch of PCB prototypes. This typically involves uploading the PCB design to the service, selecting the desired materials and features, and then waiting for the prototypes to be delivered.
- Creating a PCB prototype by hand: For more experienced designers, it is also possible to create a PCB prototype by hand using a combination of etching and soldering techniques. This method allows you to create a fully functional PCB prototype, but it is more time consuming and requires more specialized equipment and skills.

Can I create a PCB prototype myself?
The assembled PCBs that were delivered worked flawlessly. The component placement is excellent. Mis wang, the WINOW engineer in charge of our project, and I hit it off right away. She asked pertinent questions to ensure that the project was completed correctly. We had a nice, short, and to-the-point conversation.
This platform is required to charge my robotic platform's lipo batteries (rover). Excellent communication throughout the ordering process, manufacturing progress, and delivery tracking for a first-time order. Very reasonable price, particularly for the first order with a credit for a discount.
The boards arrived yesterday, and assembly has begun. Outstanding solder wetting, crisp line definition, and drill holes precisely centered on via lands.
