Introduction to PCB Assembly

PCB (Printed Circuit Board) assembly is the process of attaching electronic components to a printed circuit board to create a functional electronic device. It involves soldering components onto the PCB, which is designed to support and connect the components electrically.

PCB assembly is a crucial step in the manufacturing of electronic devices, as it determines the functionality, reliability, and durability of the final product. However, PCB assembly can be a costly process, especially for small businesses or hobbyists who don’t require large volumes of PCBs.

In this article, we’ll explore 11 ways to find low-cost PCB assembly services that can help you create high-quality electronic devices without breaking the bank.
