Frequently Asked Questions
Get clear answers about our PCB assembly capabilities, production process, lead times, and project requirements.
What is PCB assembly?
PCB assembly is the process of mounting and soldering electronic components onto a printed circuit board. The assembled board is then inspected and tested to verify its electrical and functional performance.
What types of PCB assembly do you provide?
We support surface mount technology (SMT), through-hole technology (THT/DIP), and mixed-technology assembly. Services are available for prototypes, low-volume orders, and volume production.
Do you provide turnkey PCB assembly services?
Yes. Our turnkey service can include PCB fabrication, component sourcing, SMT/DIP assembly, inspection, testing, programming, conformal coating, and finished-product assembly according to your project requirements.
What is the typical lead time for PCB assembly?
Lead time depends on board complexity, component availability, order quantity, and testing requirements. After reviewing your Gerber files, BOM, and specifications, our team will provide a project-specific production schedule.
Can you support prototype and low-volume PCB assembly?
Yes. We support prototype builds and low-volume production to help customers verify designs before mass production. Engineering review and DFM feedback can also be provided before manufacturing begins.
What files are required for a PCB assembly quotation?
Please provide your Gerber files, BOM, pick-and-place file, assembly drawings, testing requirements, and expected order quantity. Providing complete project information helps us prepare a faster and more accurate quotation.
