Micro-Perforated Strip
This guide separates the real material or manufacturing requirement from standard servo-feeder functions, then identifies the data and validation needed for a reliable line.
What the Evidence Supports
This page separates the real material or manufacturing topic from capabilities that have not been demonstrated for a HENLI servo feeder.
- This guide covers coil-strip feeding, not SMD tape transport or pick-and-place component handling.
- No vacuum micro-hole feeder plate, ionized airflow or 1200 mm/s system was evidenced.
- The distinct retained intent is very thin, highly perforated metal strip where stiffness and contact area are limited.
Evidence Required for Special Claims
The application name alone does not prove a special machine capability. Treat each claim as project-specific and record the evidence used for quotation and acceptance.
- Machine specification: identify the exact model, component ratings, environmental limits and approved material envelope.
- Performance: state the test material, feed pitch, cycle rate, sample size, measurement method and acceptance tolerance.
- Certification or compatibility: identify the applicable standard, scope, configuration and supporting report instead of relying on a general label.
What the Servo Feeder Controls—and What It Does Not
| Engineering area | Feeder or line action | Boundary |
|---|---|---|
| Carrier motion | Servo rolls index the continuous strip. | They do not place loose electronic components. |
| Contact pressure | Pressure can be reduced and concentrated on solid lands. | Too little pressure can cause slip; too much can emboss or collapse holes. |
| Support | Tables, guides and loop design can prevent sag and flutter. | The required support depends on perforation density and strip stiffness. |
| Registration | Pilots or measured features can establish final position. | Servo encoder position alone cannot correct stretched or variable hole pitch. |
Application Data to Verify Before Quotation
Use measured production data and material documentation. A feeder model should not be selected from the application name alone.
- Provide a high-resolution strip drawing and identify solid carrier lands.
- State material, thickness, width, temper and perforated open area.
- Define allowable flattening, burr contact, scratches and pitch change.
- Check roll and guide geometry against the weakest region.
- Control payoff tension and support the loop.
- Measure registration before and after production-speed feeding.
Recommended Engineering Workflow
1. Quantify stiffness
Treat perforation density and pattern as structural inputs.
2. Place contact safely
Keep rolls and guides on stable lands wherever possible.
3. Isolate tension
Use loop support so the feeder does not pull against the payoff.
4. Verify the datum
Use pilots or an agreed feature to measure downstream registration.
Frequently Asked Questions
Is this an SMD tape feeder?
No. It is a metal-strip feeding guide for stamping or forming lines.
Can 50 μm holes be fed?
Hole size alone is insufficient. Strip thickness, pattern density, lands, tension and downstream process determine feasibility.
Why keep this separate from laser-drilled strip?
This page focuses on highly perforated thin strip with limited stiffness; the laser-drilled page covers broader pre-processed patterns and cumulative pitch.

Define the Application Before Selecting a Feeder
Send the material standard and condition, width and thickness range, feed pitch, target strokes per minute, press and die details, surface requirements, line layout and the acceptance method. HENLI can review the standard feeder scope and identify any special engineering that still requires validation.
