Surface mount assembly components of any size, from 0201 passive parts to large Quad Flat Packs (QFPs) and Ball Grid Arrays (BGAs).  Our surface mount assembly processes are tightly controlled and monitored from solder paste stenciling, to pick and place, and through reflow. Utilizing multiple surface mount assembly lines with a number of machines, we can build a simple, single-sided board with just a few components or large double sided boards with over 1,000 components.

We are experienced in surface mount assembly onto traditional FR4 printed circuit boards (PCBs), flex boards, and metal core boards. Our process validation includes Automated Optical Inspection (AOI) and x-ray inspection for BGA and leadless parts.

We have many years of surface mount assembly experience in the following manufacturing processes:

  • Surface Mount LED’s on various PCB materials.
  • No clean soldering
  • RoHS compliant soldering


Surface Mount Assembly  – You are in Complete Control

The surface mount assembly soldering process used is carefully matched to your design and your constraints. The surface mount assembly PCB assembly design you submit is reviewed and any Design for Manufacturability (DFM) suggestions are made, but you are in complete control. Working together as a team alongside our trained engineers to facilitate the surface mount assembly, and the reflow surface mount soldering requirements of the individual SMD components. Circuit Works has a very high yield rate for implementing precise control of the reflow process.

X-ray inspection is used, in order, to detect the joint soldering surface mount assembly quality. For leadless parts such as QFN, DFN, and BGA packages, there is no way to perform a direct visual inspection. Therefore, by using 3D X-ray inspection, many of the issues with surface mount assembly soldering can be detected – this is very important for BGA Assemblies.

Regardless of which design stage you are at, Circuit Works is happy to work on your project and offer whatever help possible. DFM advice is offered from the earliest stages of your design. The main priority is aiding clients throughout all stages, until completion. Once your project advances, you are given a quick turnaround time for prototypes and maximum flexibility for your production runs.
