PCB Assembly Manufacturer in USA

Quick comparison of top PCB assembly manufacturers in the USA, highlighting key differentiators and capabilities.

What is PCB Assembly? Complete Process Explained

PCB assembly is the process of soldering electronic components onto a printed circuit board (PCB) to create a functional electronic device. Moreover, this critical manufacturing step transforms a bare PCB into a working electronic product that powers everything from smartphones to medical devices.

The PCB Assembly Process Breakdown

The PCB assembly process typically involves several key stages. First, manufacturers prepare the bare PCB through drilling, plating, and applying solder mask. Next, they apply solder paste using stencils to create precise patterns.

Following this preparation, the assembly process begins with component placement. Surface Mount Technology (SMT) allows manufacturers to place tiny components like resistors, capacitors, and integrated circuits with incredible precision. Additionally, Through-Hole Technology (THT) handles larger components that require stronger mechanical connections.

After component placement, the boards undergo reflow soldering in specialized ovens. Subsequently, quality control teams perform multiple inspection stages including Automated Optical Inspection (AOI), In-Circuit Testing (ICT), and Functional Circuit Testing (FCT).

“Modern PCB assembly can handle components as small as 01005 (0.4mm x 0.2mm), requiring precision equipment and experienced technicians to achieve consistent results.”
