High-Reliability SMT Assembly Services
From Rapid Prototyping to Mass Production
Are you struggling with poor soldering quality, delayed lead times, or manufacturers who won’t accept low-volume orders? At Greenspcba, we bridge the gap between high-end precision and flexible manufacturing. We don’t just place components; we ensure your hardware’s heartbeat is stable.
Why Choose Our SMT Assembly for Your Mission-Critical Electronics?
In the PCBA industry, “Standard” is the bare minimum. We go beyond by offering specialized SMT solutions for industries where failure is not an option: Medical, Automotive, and Industrial IoT.
Our Technical Edge
01005 & Fine-Pitch Expertise: Precision placement for the smallest passive components and ultra-fine pitch BGAs ($0.3mm$ pitch).
Advanced Inspection (AOI + X-Ray)
We don’t guess. Every BGA solder joint is verified via X-Ray to eliminate voids and hidden bridges.
IPC Class 2 & 3 Compliance
Whether it’s consumer-grade or mission-critical industrial grade, we adhere strictly to IPC-A-610 standards.
Capabilities & Equipment: Built for Precision
We’ve invested in high-speed, high-accuracy lines to ensure your project moves from Gerber to functional PCBA in record time.

The Professional SMT Process: How We Guarantee Quality
Many small factories skip steps to save costs. We prioritize Process Integrity to protect your cash flow from costly rework.
DFM Review (Pre-Production
Before we touch the board, our engineers review your files to catch design errors that cause soldering defects.
Solder Paste Printing
Using high-precision stencils and SPI (Solder Paste Inspection) to ensure the foundation of every joint is perfect
Automated Pick & Place
High-speed mounting with vision-correction systems for flawless alignment.
Optimized Reflow Profile
We customize temperature curves for every board, preventing thermal shock to sensitive ICs.
Multi-Stage Inspection
A combination of 3D AOI and manual QC ensures 100% yield before shipping.
Frequently Asked Questions (FAQ)
To provide an accurate quote within 24 hours, we require:
- Gerber Files (RS-274X format) including RS-274X, Silkscreen, and Solder Mask layers.
- BOM (Bill of Materials) with manufacturer part numbers (MPN) and descriptions.
- Pick-and-Place file (XY Data).
- Quantity and any special testing requirements (e.g., FCT or X-Ray).
Absolutely. We specialize in supporting startups and R&D teams. We have no Minimum Order Quantity (MOQ). Whether you need 1 board for functional testing or 500 for a pilot launch, we treat both with the same level of IPC-compliant precision.
We use a 100% Automated Optical Inspection (AOI) coverage for every board. For BGA, QFN, and other leadless components, we perform X-Ray inspection to verify solder ball integrity, checking for voids, bridging, or cold solder joints that the naked eye cannot see.
We offer three flexible options:
- Turnkey: We source all components from authorized distributors (Digi-Key, Mouser, Arrow).
- Consigned: You ship all components to us.
- Partial Turnkey: You provide the “key” ICs, and we source the common resistors and capacitors.
- Prototype: 3–5 working days (after all components are in stock).
- Mass Production: Typically 2 weeks, depending on complexity and volume. We also offer Express 24-hour service for urgent R&D deadlines.
We take IP security seriously. We are happy to sign a Non-Disclosure Agreement (NDA) before you share any design files. Internally, access to client data is strictly controlled and used only for manufacturing purposes.
