Four Major Challenges in PCB Panel Inspection

1. Dense array points: PCB panels feature dense measuring points. Manual point‑by‑point measurement involves repetitive work with extremely low efficiency, which can hardly meet mass‑production requirements.
2. Difficult measurement of micro‑dimensions: PCB traces and apertures are micron‑scale features. Manual measurement brings large errors, which may lead to misjudgment of qualified products and outflow of defective goods.
3. Incapable height‑difference inspection: Traditional inspection devices can only perform plane measurement and fail to test PCB height and step difference. Contact measurement may scratch copper foil and damage thin‑walled boards.
4. Poor data retention: Manual records on paper or spreadsheets are prone to disorder and errors. Without traceable test data, factories will face obstacles in internal quality control and customer factory audits.

Practical Application of Wanwei Automatic Video Measuring Machine

One‑time programming for automatic batch panel inspection For automatic mass PCB measurement, one‑time programming enables cyclic automatic measurement for the whole‑board array. Repeated manual alignment is no longer required, which cuts labor costs and improves overall inspection efficiency for PCB panels.

Non‑contact inspection: board‑friendly with height‑difference measurement capability Adopting optical non‑contact measurement technology, the equipment avoids scratches on copper foil and deformation of thin boards. It can measure PCB height difference and flatness, making up for the shortcomings of traditional 2‑D measuring equipment, and well‑suited for dimension inspection of ultra‑thin PCB circuit boards.

Multi‑light source & sub‑pixel grabbing to solve PCB green‑oil reflection issues Equipped with an adjustable multi‑light‑source system to mitigate green‑oil reflection and blurred edges on PCBs. Combined with sub‑pixel high‑precision grabbing algorithm, it reduces human‑induced measurement deviation and delivers stable and reliable results.

Automatic data storage & one‑click report export Inspection data are automatically archived. Test reports can be generated and exported with one click. Complete and traceable measurement data satisfy the data requirements of in‑house quality management and customer factory audits.

Diverse Optional Modules for Various PCB Inspection Scenarios
