3D SPI: Measures solder paste height, volume, and alignment (e.g., Koh Young KY8030).  

AOI (Automated Optical Inspection):  

Post-reflow defect detection (e.g., Omron VT-S730, ViTrox V810).  

X-Ray Inspection:  

For hidden solder joints (e.g., Nordson DAGE XD7600).  

2.2 Auxiliary Equipment

3. Equipment Selection Strategy  

3.1 Match Machines to Product Requirements  

High-Density Interconnect (HDI) PCBs:  

Prioritize high-accuracy printers (e.g., DEK Horizon iX) and precision mounters (ASM SIPLACE TX).  

Flexible Production (Prototyping):  

Opt for modular systems like Yamaha YSM10 (supports quick feeder swaps).  

Automotive/Aerospace:  

Invest in nitrogen reflow ovens and X-ray inspection.  

3.2 Budget Allocation Tips  

Core Equipment First: Allocate 60% to printers, mounters, and ovens.  

Phased Procurement: Start with SPI and basic AOI; upgrade later.  

Used Equipment: Consider refurbished machines from authorized dealers (e.g., Fuji NXT III modules).  

3.3 Software and Integration  

Machine Software:  

Ensure compatibility with CAD/CAM formats (Gerber, ODB++).  

Use unified platforms (e.g., ASM Line Monitor for SIPLACE machines).  

MES (Manufacturing Execution System):  

Implement real-time monitoring (e.g., Siemens Camstar, Aegis FactoryLogix).  

4. Top Brands by Equipment Type  

5. Implementation Steps
