Leading one-stop solution for PCB and assembly under one roof, specializing in small and medium runs with fast lead-time.
Why Work with Us for SMT Assembly?
PCB Assembly
Bester Tech offers one-stop, full and partial turnkey PCB assembly services to meet all customer’s requirements and save time. Our quality-driven PCB assembly process ensures that your finished project is of the highest quality.
In full turnkey PCBA, we handle everything, including making circuit boards, ordering components, online order tracking, quality inspection and final assembly.
In partial turnkey PCBA, customers are responsible for supplying us the certain components, a partial list of parts, and the remaining parts. You can order the PCBs and partial components. We will fix the remaining parts, and manufacturing and assembly will be handled by us.

At MOKO, we perform both manual and automated through hole PCB assembly according to different project requirements. Generally speaking, we do hand component insertion and hand soldering for highly complicated assembly projects and use automated through-hole PCBs techniques for small-volume production.
PCB Assembly Process
One of the most important factors in the overall efficiency of each PCB assembly project is the client’s understanding of our process. The number of steps involved in the PCB assembly process depends upon the specific nature of the project in question, as illustrated below, and each of these steps is explained briefly in the following sections.
For simplicity’s sake, some intermediary stages are not shown; for example, each stage includes individual inspection upon completion. Being familiar with this process in advance, a savvy engineer can design their PCB specifically for a fast and efficient assembly process by minimizing the overall number of steps required.
DFM Check
DFM checks our client’s PCB design and looks for issues that may influence the final product negatively, such including missing, redundant or potentially problematic features. And the consistency across different design documents like BoM and Gerbers.
IQC
Inspect all incoming materials and handle quality problems before the SMT assembly process. Bester IQC and procurement team will check for model numbers, shape, sample test, etc to ensure all parts used are of the highest quality.
Solder Paste Printing
Solder paste printing is the actual first step in PCB assembly manufacturing process that can apply solder paste to the appropriate, necessary areas on the PCB using stencil and squeegees.
SMD Components assembly
Pick and Place SMD components to the programmed location at high speed using automated Pick&Place machines after solder paste is correctly applied to bare PCBs.
Reflow Soldering
After SMD components are placed on the boards, they are sent through reflow machines to have the solder paste to reflow, attach components and create permanent solder joints.
THT Components Assembly
Pick and Place THT components to the programmed location at high speed using automated Pick&Place machines for the wave soldering process.
wave soldering
Wave soldering is a method of PCB Assembly that involves sending boards on a conveyor through a wave of molten solder that is used to attach through-hole components to the boards.
AOI & X-ray
Inspect and verify that no mistakes have been made and that all parts have been correctly placed using automated optical inspection(AOI) and X-Ray technology and machines.
Final inspection & repairing
The final inspections include visual inspection by our quality assurance team and post AOI inspection for flaws and functions. It’s also known as functional test.
QC / packaging
All assembled boards are packaged per clients’ request in anti-static packaging and be prepared for shipping under our QC team.
