Functions:

This is an international high-speed in-lineAOI, featuring high-speed intelligent cameras and a new-gen light sourcesystem. It offers more delicate images and a 40% faster detection speed thanprevious models, effectively meeting the needs of international high-speedproduction lines. To address the issue of irregularly shaped boards failing toreach the loading position accurately, it can be applied in multiple spots likeafter printing, before and after the furnace, achieving multi-functionality.

Main Detection Contents:

• Solder Paste Printing:

• Absence or presence,misplacement, too little or too much solder, open circuit, bridging,contamination, etc.

• Component Defects:

• Missing parts,misaligned parts, skewed parts, tombstoning, side-standing parts, flippedparts, wrong parts (OCV), damaged parts, reverse installation, etc.

• Soldering Point Defects:

• Excessive solder,insufficient solder, cold solder joints, bridging, copper foil contamination,etc.   

Dingchang has introduced 10 sets of VCTA-A410 AOI detectors.

Dingchang has introduced 10 sets ofVCTA-A410 AOI detectors. AOI inspects PCBs and other electronic componentsvisually to ensure proper placement and soldering of PCBA components.

Typically, there's manual visual inspectionbefore and after the SMT reflow oven. Some manufacturers skip the pre-reflowAOI.

AOI offers intelligent visual inspectionfor printed circuit board production. Sensors can automatically scan for allcatastrophic failures (like component breakage) and quality issues, effectivelyenhancing the durability of PCBs and PCBA.

Main Detection Contents:

• Solder Paste Printing:

• presence or absence,skew, insufficient or excessive solder, open circuit, contamination;

• Component Defects:

• missing component,displacement, skew, tombstoning, side standing, component flipping, wrongpolarity, wrong component, damage;

• Soldering Point Defects:

• excessive solder,insufficient solder, solder bridging;

• Wave Soldering Detection:

• insufficientsolder, excessive solder, soldering point bridging or short circuit, coldsolder joint, void.

Dingchang has introduced 2 sets ofEfficiency E680 intelligent first article inspectors.

For the PCBA undergoing first article inspection, the machine automatically generates an inspection program byintegrating the BOM list, coordinates, and high-definition scanned images. Itcan quickly and accurately detect components, auto-judge the results, andgenerate a first article report, boosting production efficiency and accuracywhile strengthening quality control.

Actual Effects:

Since using the intelligent first article inspectorslast year, the production line has submitted first articles for inspection over 4,000 times. The inspectors detected around 30 first article errors with a 100% detection rate, effectively preventing large-scale quality issues caused byfirst article errors.   

Dingchang has introduced 2 sets of X-RAYnon-destructive fluoroscopy detectors.

These detectors are used for qualityinspection of BGA (Ball Grid Array), CSP (Chip Scale Package), flip chip, theinterior of semiconductors, and multi-layer circuit boards, as well asinspection after rework. ELT's unique image detection technology enablesaccurate judgment of cold soldering.

Main Detection Contents:

• The soldering condition of the PCB board.

• Detection of short circuits, open circuits,voids, and cold soldering.

• Inspection of IC (Integrated Circuit)packaging.

• Detection of components such as capacitorsand resistors.

• Internal flaw detection of electric heatingtubes, lithium batteries, pearls, precision devices, etc.

• Internal flaw detection of metal devices.

Manual Visual Inspection

Conduct manual visual inspection on thedetection area of the PCB (Printed Circuit Board), which relies entirely on theworkers' experience.

Actual Measurement Results:

After the first PCBA (Printed Circuit BoardAssembly) is mounted, inspect the position of the components to check whetherthey are correctly placed.

It can detect issues such as missingcomponents, incorrect polarity, soldering bridging, and some cold solderingsituations.
