Component pin tips: select the useful height region with a thin light plane

The source pin light makes the tips stand out while reducing the bright housing/background seen in the comparison. It is a useful contrast strategy for locating leads, separate from measuring their height or proving electrical contact.

Select a useful tip signal before asking software to locate it.

The challenge

A locating algorithm can be distracted by the component body, pin shafts and fixture below the tips. The useful signal is often the tip region itself.

How it was solved

The source names LS-BRV150120-W2. This is one catalog assembly with two inward-facing light rails, not two complete units in the quote.

The proposed frame is aligned around the pin-tip plane. Frame position, part supports and illumination-plane thickness are schematic; a real setup must establish the useful height interval.

Why it works

  1. 1

    A narrow directional light field can suppress background features while retaining the pin-tip signal.

  2. 2

    A bright tip is not a calibrated height measurement. The source does not give a plane-thickness specification, height rejection threshold or pin-location uncertainty.

Evidence you can inspect

Visible in the images

The source comparison isolates the pin tips more strongly than its ring-light reference; a separate five-pin example retains visible tip regions.

What the source reports

The source reports improved pin-location contrast, without a calibrated height plane, positional accuracy or production false-call rate.

How to use this evidence

An application-lab lighting demonstration, not a customer deployment or a qualified production inspection. Proposed camera, lens, fixture and scene spacing require a fresh trial. Source observations do not establish a defect-size limit, accuracy guarantee or production false-call rate.

From image contrast to a production decision

What to validate on your part

  1. 01

    Align the actual tips

    Adjust the light and fixture using known good leads and document the useful illumination-height interval.

  2. 02

    Challenge the background

    Include component-body finish, pin tilt, housing reflections and fixture-position variation.

  3. 03

    Validate localization

    Measure repeated tip locations and test known missing/displaced leads; use a separate calibrated method if height is required.

"Tested" identifies the part named in the source. "Our pick" is a proposed alternative or supporting part. Confirm colour, optics, controllers, power supplies, cables and mounting before ordering.

Lens-to-part in proposed scene150 mm; printed working-distance pair
Mounting (proposed)LS-BT-XZ-G-6-6045 · catalog test station with two lighting holders

Mount the optics with intent

The station is an optical test bench, with its two lighting holders included in the catalog listing. The 3D column and base follow the published height and footprint. Carriages, clamps and part supports are schematic: confirm camera screw pattern, lens support, light fasteners, permissible load and actual travel before ordering.

Complete the electrical system

Select a controller against the exact light voltage, drive mode and power, then confirm camera data/power/I/O cables and a suitable PC. These are not silently added to the proposed optical kit.

The configurator opens with this study's camera, lens, light and station picked. Swap any part, check fit and price, then buy or ask for a quote.

Camera and available lens CAD are published models. Light envelopes and the station base/height use printed dimensions. Part shapes, brackets, holders, shielding and spacing are illustrative; they are not reconstructions of a source part or a complete mechanically validated assembly. Light paths explain the proposed arrangement and do not simulate optical performance. The proposed field is derived from the printed camera pixel dimensions and the stated lens magnification/working-distance pair, not measured from the source capture.
