Lead Frame And Substrate Inspection
Inspect Before You Bond. Prevent Failure Before Assembly.
Inspect Before You Bond. Prevent Failure Before Assembly.
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.
Scratches, dents, or oxidation on the lead frame surface may go undetected in visual checks, leading to bonding failure.
Substrate thickness, paddle depth, or pad spacing variations cause die misplacement or electrical mismatch.
Mechanical warpage due to improper storage or handling can cause poor die attach, especially in multi-layer substrates.
Human error and subjective judgment reduce reliability and throughput under high-volume demands.
Captures surface irregularities, corrosion, scratches, and dents using high-resolution visual and depth scanning.
Measures pad pitch, bond fingers, paddle flatness, and outline dimensions against golden specs.
Uses machine vision with 3D reconstruction to detect bending or structural warpage in substrates and frames.
Automatically classifies defects and routes defective units to rework bins or rejects them, no operator input needed.
We begin by mapping the inspection point between cleaning and die attach stages, integrating the system with your substrate loader/unloader and frame handler.
Combining area-scan cameras and laser triangulation sensors, we enable full-surface and height-map acquisition for each lead frame or substrate in motion.
Our AI model is trained on real-world defect libraries from your past rejects, scratches, oxide marks, pad shifts, to achieve context-specific classification.
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.

What Vision AI Can Actually See Let’s talk about the logistics industry’s strange addiction to buying new hardware. When confronted with a blind spot in the yard, our collective reflex is almost always to purchase another piece of plastic, attach a battery to it, and bolt it onto a steel box. We love sensors. We […]

It usually arrives on a Tuesday morning. The subject line is aggressively vague, but the attachment tells you everything you need to know: a blurry photograph of a violently dented shipping container, accompanied by an invoice for the repair. Your terminal is officially being blamed for the damage. What follows is the most frustrating, time-consuming […]

Let’s talk about the most terrifying event in terminal management: the retirement party. Every container yard has one. That veteran dispatcher or yard manager, let’s call him Frank. Frank operates with a battered clipboard, a radio held together by duct tape, and an encyclopedic mental map of five thousand identically rusted steel boxes. When a […]
