Frequently Asked Questions

Everything you need to know about sub contract PCB assembly

Sub contract PCB assembly is a service where specialized manufacturers handle the assembly of printed circuit boards on behalf of other companies. This includes component sourcing, PCB fabrication, assembly, testing, and quality control, allowing businesses to focus on their core competencies while ensuring high-quality electronic manufacturing.

Sub contract PCB assembly services include Surface Mount Technology (SMT) assembly, through-hole assembly, mixed technology assembly, turnkey PCB assembly, consignment assembly, prototype assembly, low to high volume production, box build assembly, and testing services including functional, in-circuit, and flying probe testing.

PCB assembly lead times vary based on complexity and volume. Prototype assemblies can be completed in 3-5 business days, while standard production runs typically take 1-2 weeks. High-volume production may require 2-4 weeks. Rush services are available for urgent requirements with expedited turnaround times.

Professional sub contract PCB assembly follows international quality standards including IPC-A-610 for acceptability of electronic assemblies, ISO 9001 quality management, ISO 13485 for medical devices, AS9100 for aerospace applications, IATF 16949 for automotive, and RoHS compliance for environmental requirements.

Minimum order quantities vary by provider and complexity. Many sub contract PCB assembly services offer flexible MOQs starting from single prototypes to millions of units for high-volume production. Prototype services typically have no minimum order requirement, while production runs may have MOQs of 50-100 units depending on the complexity.
