Relational FAQs

What is PCB assembly?

PCB assembly is the process of placing and soldering electronic components onto a printed circuit board (PCB) to create a functional electronic device. This process uses techniques such as through-hole, surface-mount technology (SMT), or a combination of both (mixed technology).

What is the difference between SMT and through-hole PCB assembly?

Surface-Mount Technology (SMT): A fast, automated process where components are soldered directly onto the PCB’s surface. It is efficient and suitable for high-volume production.
Through-Hole Technology: Involves inserting component leads through pre-drilled holes in the PCB and soldering them on the reverse side. This method is slower but offers stronger mechanical bonds, making it ideal for heavy-duty applications.

What is the difference between SMT and SMD?

SMT (Surface-Mount Technology) involves mounting components directly onto a PCB, while SMD (Surface-Mount Device) refers to the components themselves. SMT enables efficient mass production, while SMDs allow for smaller, high-density circuit designs with enhanced performance.

How does PCB design relate to PCB assembly?

PCB design is the blueprint for the assembly process, providing a schematic layout that specifies component placement, electrical pathways, and design rules. Assembly brings the design to life by placing and soldering components onto the board based on the design specifications.

What quality control measures do you use during PCB assembly?

We ensure top-quality PCB assembly with ISO9001, ISO14001, IATF16949, ISO13485, and ISO17025 compliance. Our process includes AOI for defect detection, X-ray for BGA solder verification, conformal coating for protection, and ICT to ensure flawless functionality.

Do you offer full turnkey PCB assembly services?

Yes, we provide full turnkey services, managing the entire production process from component sourcing and procurement to assembly and quality testing. This allows clients to focus on their designs while we handle manufacturing and logistics. Learn how our turnkey services integrate with Kingbrother’s printed circuit board solutions for end-to-end manufacturing.

Can you provide quick-turn or express PCB assembly services?

Yes, we offer rapid PCB assembly services for urgent projects. For instance, a 4-layer PCB that usually takes 6 days to produce can be completed in less than 72 hours with our quick-turn service.

Can I supply my own components for the assembly process?

Yes, we offer consigned assembly services where you can provide your components. Please ensure all parts are labeled and accompanied by a detailed Bill of Materials (BOM).

What types of PCBs can you assemble?

We assemble a wide range of PCBs, including single-sided, double-sided, multilayer, flexible, and rigid-flex PCBs, to meet the demands of diverse applications, from consumer electronics to industrial equipment.
