SPAN-15MM Radial Lead Auto Inserter for Extended Lead THT PCB Assembly

A power-supply capacitor with a 14mm lead span looks ordinary until your standard radial inserter refuses it. Then that one component becomes a manual station, an operator, and a slow, error-prone step wedged into an otherwise automated line. The SPAN-15MM Radial Lead Auto Inserter exists for exactly this gap: components with extended lead spacing or longer lead lengths that exceed the reach of standard radial inserters, which is why power-supply, LED-driver, and industrial-control boards keep hitting the same wall.

The cost you haven't named: the extended-lead exception

Most process engineers spec a radial inserter for the common parts and quietly hand-place the rest. The exception is not free.

A manual station inside an automated cell. Every extended-lead part that the machine cannot reach becomes a human step, breaking the flow and capping throughput at that operator's pace.
Lead damage and misinsertion. Bending and pressing long leads by hand raises the risk of cracked leads, misaligned insertion, and lifted pads that surface only at test.
Ergonomic and fatigue cost. Long-lead components are awkward to handle; repetition across a shift degrades consistency and increases turnover risk on a dull task.
Mixed-model changeover drag. EMS lines running many customer boards accumulate these exceptions, and each one adds setup time and training overhead nobody budgets for.

The Four-Point Extended-Lead Fit Audit

Before committing to an inserter, qualify the problem with a repeatable audit. Call it the Four-Point Extended-Lead Fit Audit.

1. List the out-of-reach parts. Pull the bill of materials for your recurring boards and flag every radial component whose lead span or lead length exceeds your current inserter's rated range.

2. Measure the volume share. Estimate how many of those parts appear per board and across your monthly volume. This separates a rare exception from a structural bottleneck.

3. Cost the manual step. Add up the labor minutes, rework rate, and ergonomic risk of hand-inserting those parts today. The number is usually larger than it looks.

4. Define the acceptance range. Set the maximum lead span and lead length the next machine must handle, plus insertion and clinch quality you will accept at incoming inspection. That becomes your quotation spec.

The vehicle: SPAN-15MM Radial Lead Auto Inserter

The audit maps straight onto how the SPAN-15MM is specified and used.

List the out-of-reach parts → 15mm lead span. The machine is engineered for a 15mm maximum lead span, automating radial components that exceed standard inserter reach and eliminating that manual step.
Measure the volume share → suited to volume runs. It handles extended-lead radial components at speeds suited to medium- and high-volume production, reducing per-unit labor cost on power-supply and driver boards.
Cost the manual step → full automation of the cycle. Component feeding, lead presentation, insertion, and clinching are automated end to end, removing the hand-bend-and-press risk.
Define the acceptance range → mixed-cell integration. It can sit alongside standard radial inserters in a mixed-model cell, taking the XL-span components while other machines handle shorter-lead parts.

Specification note: insertion rate (CPH), component size range, clinch form, and footprint should be confirmed at quotation, because they depend on your specific lead geometries and board stack.

A note on line layout. In practice, the SPAN-15MM rarely runs alone. On a typical power-supply line, it follows the axial and standard radial inserters, taking only the XL-span components so the rest of the cell stays at full speed. Boards then move to wave or selective soldering with leads already clinched and trimmed, which removes a rework loop that manual insertion tends to introduce. For EMS shops quoting mixed customer work, that consistency is what protects margin when a new board arrives carrying a lead geometry nobody previewed in advance.

The loop: re-audit at every product change

Product mixes shift, and so does the share of extended-lead parts. Build a loop: every time a new board enters the line, run the Four-Point Extended-Lead Fit Audit again and check whether the SPAN-15MM's 15mm span still covers the worst-case part. Review insertion and clinch quality monthly from incoming inspection data, and feed exceptions back to the quotation spec. The loop keeps the machine matched to reality instead of to the assumptions you made on day one.

FAQ

What lead span does the SPAN-15MM handle?

It is engineered for a 15mm maximum lead span, covering extended-lead radial components that standard radial inserters cannot reach.

Which boards use it most?

Power-supply modules, LED-driver boards, industrial-control boards, and automotive electronics where filter capacitors, inductors, relay coils, and transformers carry longer leads.

Does it replace manual insertion entirely?

For the extended-lead radial parts within its 15mm span, yes — feeding, lead presentation, insertion, and clinching are automated.

Can it run in a mixed-model cell?

Yes. It integrates alongside standard radial inserters, handling XL-span components while other machines handle shorter-lead parts.

What should I confirm before ordering?

Lead span and length range, insertion rate, clinch form, and machine footprint are confirmed at quotation against your component samples.
