PCB Assembly Services – Full Turnkey Prototype to Production | Golden Weald

Professional PCB Assembly Services: A Full Turnkey Solution from Prototype to Production

GoldenWeald is a leading PCB Assembly (PCBA) service provider, dedicated to delivering high-quality, fast, and cost-effective circuit board manufacturing and assembly solutions for global engineers, startups, and large-scale manufacturers. We specialize in both Surface Mount Technology (SMT) and Through-Hole Technology (THT), handling everything from simple double-sided boards to complex High-Density Interconnect (HDI) layouts.

Why Choose Our PCB Assembly Services?

  1. End-to-End Turnkey Solution

    • Complete Peace of Mind: Simply send us your Gerber files, BOM, and centroid data. We manage the entire process: component sourcing, PCB fabrication, precision assembly, comprehensive testing, and final delivery. Our partnerships with leading global component suppliers ensure authentic parts and reliable supply.

  2. Unmatched Speed and Flexibility

    • Rapid Prototype Assembly: Need a board urgently? We offer quick-turn prototyping in as little as 24 hours to accelerate your development cycle.

    • Low to Mid-Volume Production: Whether your need is 100 or 10,000 units, we provide competitive pricing and stable capacity to seamlessly scale your product from lab to market.

  3. Advanced Technology & Quality Assurance

    • State-of-the-Art Equipment: Featuring fully automated high-precision SMT pick-and-place machines, multi-zone reflow ovens, AOI (Automated Optical Inspection), X-Ray inspection (for BGA and QFN solder joint verification), and flying probe testers.

    • ISO 9001 Certified: We adhere to strict international quality standards. Every board undergoes multiple inspection checkpoints to ensure a zero-defect delivery.

    • Engineering Support: Our team provides DFM (Design for Manufacturability) analysis to optimize your design before production, saving you cost and improving yield.

  4. Transparent Pricing & Instant Quotes

Frequently Asked Questions (FAQ)

Q1: How is the price for PCB assembly calculated?
A: The cost is primarily determined by PCB complexity, component costs, number of solder points, order quantity, and special processes. Use our online quote tool for the most accurate and transparent pricing.

Q2: Do you offer consigned assembly if we provide the components?
A: Yes, we offer full flexibility. You can choose our Full Turnkey service (we source everything) or a Consigned/Kitted model (you provide the components).

Q3: What is your typical turnaround time?
A: For standard prototype orders, turnaround is typically 3-5 business days. The exact time depends on component availability and project complexity. We offer expedited options for faster delivery.

Q4: How do you ensure the reliability of BGA assembly?
A: We ensure BGA reliability through high-accuracy placement and mandatory X-Ray inspection. This allows us to non-destructively check for voids, bridges, and cold joints within the solder balls.
