Lead Frame And Substrate Inspection

Inspect Before You Bond. Prevent Failure Before Assembly.

LEAD FRAME AND SUBSTRATE INSPECTION_

ENSURE THE BASE IS FLAWLESS. AVOID BONDING ERRORS AT THE ROOT.

LEAD FRAME AND SUBSTRATE INSPECTION_2

Lead frames and substrates form the physical base for semiconductor packages, any warpage, contamination, or dimensional fault at this level can cause bonding issues, electrical shorts, or total package failure. Manual inspection is inconsistent, and traditional 2D tools often miss warpage or multilayer misalignment. AI-powered Lead Frame and Substrate Inspection uses advanced 2D/3D computer vision to detect surface defects, warpage, and structural misalignment before die attach or wire bonding. With micron-level resolution and intelligent classification, the system ensures only flawless frames proceed to the next stage.

OUR HOLISTIC VIEW TO CHALLENGES & FEATURES

Challenges

Surface Defects Go Unnoticed

Surface Defects Go Unnoticed

Scratches, dents, or oxidation on the lead frame surface may go undetected in visual checks, leading to bonding failure.

Dimensional Tolerance Misses

Dimensional Tolerance Misses

Substrate thickness, paddle depth, or pad spacing variations cause die misplacement or electrical mismatch.

Warpage and Bending Detection Gaps

Warpage and Bending Detection Gaps

Mechanical warpage due to improper storage or handling can cause poor die attach, especially in multi-layer substrates.

Manual Inspection Inconsistency

Manual Inspection Inconsistency

Human error and subjective judgment reduce reliability and throughput under high-volume demands.

Features

2D & 3D Surface Inspection

2D & 3D Surface Inspection

Captures surface irregularities, corrosion, scratches, and dents using high-resolution visual and depth scanning.

Micron-Level Dimensional Analysis

Micron-Level Dimensional Analysis

Measures pad pitch, bond fingers, paddle flatness, and outline dimensions against golden specs.

Warp & Bow Detection Algorithms

Warp & Bow Detection Algorithms

Uses machine vision with 3D reconstruction to detect bending or structural warpage in substrates and frames.

Defect Classification & Sorting

Defect Classification & Sorting

Automatically classifies defects and routes defective units to rework bins or rejects them, no operator input needed.

WHO BENEFITS FROM LEAD FRAME & SUBSTRATE INSPECTION?

LEAD FRAME AND SUBSTRATE INSPECTION_3
  • Assembly Line Operators – Reduce die bonding rejections caused by substrate inconsistency.
  • Quality Assurance Teams – Eliminate inspection subjectivity and improve traceability across batches.
  • Substrate & Frame Vendors – Automate outgoing inspection with documentation for OEM compliance.
  • Packaging Engineers – Ensure long-term reliability of stacked or embedded packages by validating base structures.

BUILDING AND DEPLOYING PROCESS

Component Handling Integration

Component Handling Integration

We begin by mapping the inspection point between cleaning and die attach stages, integrating the system with your substrate loader/unloader and frame handler.

Hybrid Camera + Laser Profile Setup

Hybrid Camera + Laser Profile Setup

Combining area-scan cameras and laser triangulation sensors, we enable full-surface and height-map acquisition for each lead frame or substrate in motion.

Defect Model Training Using Historical Samples

Defect Model Training Using Historical Samples

Our AI model is trained on real-world defect libraries from your past rejects, scratches, oxide marks, pad shifts, to achieve context-specific classification.

Sorting Interface + MES Integration

Sorting Interface + MES Integration

Inspection outcomes are sent to the MES (Manufacturing Execution System) in real time, triggering robotic sorters or binning logic to separate units by defect class or reworkability.

The Technical Anatomy of a Parking Twin

Every city breathes in patterns. Cars move, pause, and disperse in a rhythm that repeats itself through hours and seasons. Beneath this rhythm lies a kind of language, the pulse of motion that defines how urban life organizes itself. Yet, for all the technology that has reshaped cities, one of the simplest and most visible […]
