PCB Assembly FAQ
Keep Best PCBA are offering full-service PCB assemblies from consigned to full turnkey manufacturing, material procurement, assembly, test, system integration, inspection and advanced technologies.
Our staff engineers work with you, our customer, throughout the initial design and development process to ensuremanufacturability, product quality, and consistency.
The total lead time depends on component procurement and PCB assembly. To optimize efficiency, we overlap processes: once we receive your Gerber files and BOM, we begin stencil preparation and PCB fabrication in parallel with parts sourcing.
For details, see our PCBA capabilities.
Yes, we do partial assemblies. Please tell us which components you do not want to be placed by noting in your BOM “Do Not Include (DNI)” or DNP ( Do not Placed ) or NO need assembly
SMT Assembly involves the following
Application of solder paste
Placing the components
Soldering the boards with a reflow process.
Yes, a combination of both manual soldering and automated soldering can be used. Manual soldering only for prototypes if no special request (machine is a must)
SMT PCB come with a wide range of advantages, the most important ones being the fact that they are suited for printed circuit boards which offer small size and reduced weight.
Yes. This practice is called partial Turn-key. You can supply some parts, and we source the rest of the parts on your behalf. We will ask for your approval for anything that is not sure at our side. In case parts crossing or substitution is needed, we will again ask for your final approval.
Design Requirements:
Via-on-pad: Must be resin-filled for reliable soldering.
Via-near-pad: Must be tented/solder-mask-filled to prevent defects.
We ensure high-quality BGA assembly through strict process controls.
