Frequently Asked Questions

What is PCB circuit board assembly?

PCB circuit board assembly is the comprehensive process of soldering and mounting electronic components onto a printed circuit board to create a functional electronic device. This includes surface mount technology (SMT) for miniature components, through-hole assembly for larger parts, and complete turnkey manufacturing services that encompass component procurement, assembly, testing, and delivery.

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

SMT (Surface Mount Technology) involves placing components directly on the surface of the PCB without drilling holes, allowing for smaller, more compact designs with higher component density. Through-hole assembly involves inserting component leads through drilled holes in the PCB and soldering them on the opposite side, providing stronger mechanical bonds ideal for components that experience physical stress or require heat dissipation.

What is the typical lead time for PCB assembly?

Lead times vary based on complexity, component availability, and order quantity. Prototype assemblies typically take 3-7 business days, while standard production runs require 2-4 weeks. Rush services are available for urgent requirements with expedited processing that can deliver prototypes in 24-48 hours for an additional fee.

What file formats are needed for PCB assembly?

Standard requirements include Gerber files (RS-274X format) for copper layers and silkscreen, drill files (Excellon format), Bill of Materials (BOM) in Excel or CSV format with manufacturer part numbers, and centroid/pick-and-place files for component locations. Additional documentation like assembly drawings, schematics, and special instructions are helpful for ensuring accurate assembly.

What quality standards do PCB assemblers follow?

Professional PCB assembly services follow IPC-A-610 workmanship standards (Class 2 for commercial products, Class 3 for high-reliability applications), ISO 9001 quality management certification, and industry-specific certifications such as ISO 13485 for medical devices, IATF 16949 for automotive electronics, and AS9100 for aerospace applications.

Can you assemble prototypes and production quantities?

Yes, reputable PCB assembly services handle both low-volume prototype runs starting from a single unit and high-volume production runs of thousands or millions of boards. Flexible processes and equipment configurations allow seamless scaling from prototyping through production without requiring design changes or re-qualification.

What is turnkey PCB assembly?

Turnkey PCB assembly is a complete service where the assembly provider handles everything from component procurement through final assembly, testing, and packaging. This eliminates the need for customers to source components separately, manage inventory, or coordinate multiple suppliers, simplifying the manufacturing process and reducing time to market.

How do you ensure component authenticity?

Components are sourced exclusively from authorized distributors and franchised suppliers with full traceability documentation. Multiple verification checks include visual inspection for packaging consistency, date code verification, manufacturer confirmation, and sample testing when necessary. Counterfeit mitigation procedures follow industry best practices to ensure only genuine components are used in assemblies.
