PCB Assembly Process

NextPCB provides efficient and high-quality turnkey PCB assembly service to its customers. In order to achieve the fastest possible turnaround of the highest quality product, we continuously strive to improve our services and to make each step as efficient as possible. One of the most important factors in the overall efficiency of each PCB assembly project is the client’s understanding of PCB assembly process.

This page provides an overview of some standard but important turnkey PCB assembly process. This is a brief overview only. If you are interested, you're more than welcome to visit our factory.

Incoming Material Inspection

An incoming inspection, also known as a receiving inspection or material inspection, validates the quality of purchased raw materials based on set acceptance criteria. It is performed by quality assurance personnel in the manufacturing facility to resolve quality issues during pre-production. Incoming inspection results follow an identification tagging system to determine required actions when an item is tagged as accepted, conditionally accepted, or rejected.

NextPCB team will do full check on incoming material inspection to control the assembly quality. Components counting, package confirm, quantity confirm are in this process.

SMT Solder Paste Printing

Solder paste (or solder cream) is a material used in the manufacture of printed circuit boards to connect surface mount components to pads on the board. Before soldering, all PCB boards should print solder paste so that the components can be soldered by pick & place machine.

Pick & Place Assembly

Once bare PCBs printed solder paste, they are moved to NextPCB’s automated Pick & Place machines for the actual mounting of components on their associated pads. Part placement is 100% machine automated for maximum accuracy and efficiency, and uses the project’s Centroid file for component coordinates and rotation data.

The boards are again inspected after components have been mounted to ensure all placements are accurate before the soldering process begins.

This stage might need to be performed multiple times, depending upon the specifics of a given project. Double-sided SMT boards require one round of placement for the top and one for the bottom, and projects requiring wave soldering due to a high number of through-hole parts will normally have their components machine-placed as well.
