SPI, AOI, X-ray and component counting: which PCB inspection method catches which defects, and how inspection machines fit into SMT and THT lines.

Manual counting and weighing reels cost EMS factories hours every week and quietly corrupt inventory data. Southern Machinery's SMD Components Counter uses X-ray imaging to count tape-and-reel SMD components in seconds with better than 99.8% system accuracy (AX6000). This buyer's guide covers what the machine is used for, five real applications in receiving, kitting, and warehouse control, how it fits a complete PCB assembly line, key selection parameters, and the ROI of accurate component counting. Established in 2011 in Shenzhen, China, Southern Machinery serves 237+ global customers with SMT, THT, wave soldering, and inspection automation.

T-870A BGA Rework Station by Southern Machinery: controlled hot-air rework for BGA, QFN, and CSP packages with optical alignment and repeatable reflow profiles.

Southern Machinery S580 strain gauge and SDL series PCB strain measurement device quantify board stress to prevent solder joint cracks in SMT assembly.
The AX6000 SMD X-Ray Chip Counter helps EMS factories quickly count tape-and-reel components without manually unreeling parts. This article explains how it supports warehouse receiving, line-side return counting, barcode
The SR-430A BGA Rework Station gives PCB repair teams a controlled way to solder and desolder BGA components instead of relying on risky hand repair. This article reviews verified specs from the catalog, including closed
