Machinery Breakdown Insurance for PCB & Assembly Equipment: A Practical UK Guide

Introduction: why PCB assembly kit needs specialist cover

If you run a PCB manufacturing or electronics assembly operation, your equipment is the heartbeat of the business. A single failure on a pick-and-place line, reflow oven, wave solder machine, compressor, or test system can stop output instantly. Even when parts are available, specialist engineers, calibration, and validation can take days or weeks.

Machinery Breakdown Insurance (often called Engineering Insurance or Equipment Breakdown) is designed for sudden and unforeseen mechanical or electrical failure. It’s different from standard commercial property insurance, which usually focuses on “external” events like fire, flood, storm, theft, and impact damage.

This guide explains how machinery breakdown insurance works for PCB and assembly equipment, what to insure, what to watch for in the small print, and how to build a sensible claim-ready setup.

What is Machinery Breakdown Insurance?

Machinery breakdown insurance covers the cost of repairing or replacing insured plant and machinery following a sudden, accidental breakdown.

For PCB and assembly businesses, that typically means cover for:

• Mechanical failure (bearings, motors, conveyors, pumps, fans)
• Electrical failure (short circuits, arcing, control panel faults)
• Electronic failure (drives, PLCs, boards, sensors)
• Operator error (depending on wording)
• Failure of safety devices leading to damage

It can be arranged as:

• A standalone engineering policy
• A section within a commercial combined policy
• A package for manufacturers with optional add-ons (e.g., deterioration of stock)

Why standard property insurance often isn’t enough

Many businesses assume “we’re insured for the building and contents, so the machines are covered.” The issue is cause of loss.

Property policies commonly cover:

• Fire and smoke
• Flood and escape of water
• Storm
• Theft
• Malicious damage
• Impact

But they often exclude internal breakdown such as:

• Mechanical or electrical failure
• Gradual wear and tear
• Breakdown due to lack of maintenance

So if your reflow oven’s control board fails, or a servo drive on a placement machine burns out, you may find it’s not covered under a standard contents section.

Typical PCB & assembly equipment to include

A good starting point is to list anything that would materially stop production or create a major cost if it failed.

SMT line equipment

• Pick-and-place machines
• Stencil printers / screen printers
• Reflow ovens
• Wave solder machines
• Selective soldering systems
• Conveyors and board handling systems
• AOI (Automated Optical Inspection)
• SPI (Solder Paste Inspection)
• X-ray inspection systems

Through-hole and finishing

• Depaneling machines
• Conformal coating machines
• Curing ovens
• Ultrasonic cleaners
• Label printers and marking systems

Test and measurement

• ICT (In-Circuit Test)
• Flying probe testers
• Functional test rigs
• Environmental chambers
• Calibration benches

Support plant (often overlooked)

• Air compressors and dryers
• Nitrogen generators
• Extraction and filtration systems
• Chillers and cooling units
• UPS systems
• Power distribution boards
• ESD monitoring systems

CNC / fabrication (if applicable)

If you also do in-house PCB fabrication or mechanical work:

• CNC routers
• Drill machines
• Laser cutters
• Plating line equipment

What does a machinery breakdown policy usually pay for?

Cover varies by insurer, but common insured costs include:

1) Repair or replacement of the damaged part

This is the core of the cover: parts, labour, and the work required to put the machine back into working order.

2) Expediting expenses (optional)

If you need to pay extra to get the line running sooner, you may be able to insure:

• Overtime labour
• Express shipping
• Emergency call-out charges
• Temporary hire of certain equipment

3) Business interruption from breakdown (optional but important)

This is often the difference between a painful incident and a business-threatening one.

Business interruption (BI) linked to machinery breakdown can cover:

• Loss of gross profit due to reduced output
• Increased cost of working (e.g., outsourcing assembly)

Key points to check:

• Indemnity period (e.g., 3, 6, 12, or 24 months)
• Waiting period/excess time (e.g., first 24–72 hours not covered)
• Whether cover applies to partial loss of output

4) Deterioration of stock (optional)

If breakdown causes temperature or humidity control to fail, you may need cover for:

• Moisture-sensitive devices (MSDs) damaged by poor storage conditions
• Adhesives, resins, or coatings spoiled by temperature issues
• Components damaged in ovens or chambers

Common causes of breakdown in electronics manufacturing

Insurers like to understand your risk controls. From a practical standpoint, these are common triggers:

• Power quality issues (surges, brownouts, phase imbalance)
• Cooling failures leading to overheating
• Contamination (dust, flux residue, oil mist)
• Compressed air quality problems (water/oil in lines)
• Misfeeds and jams causing mechanical strain
• Software/firmware faults (sometimes excluded if “data/software” isn’t insured)
• Poor maintenance or missed servicing

Key exclusions and grey areas to watch

This is where policies differ. Always check the wording, but common exclusions include:

Wear and tear / gradual deterioration

Breakdown cover is typically for sudden events, not predictable degradation.

Consumables and tooling

Items like:

• Belts, nozzles, squeegees
• Filters
• Lamps/heaters (sometimes)
• Fuses may be excluded or limited.

Maintenance-related issues

If a failure is linked to lack of servicing, insurers may reduce or decline a claim.

Known defects and recalls

If a manufacturer has issued a recall or known defect notice, insurers may treat this as non-fortuitous.

Software, data, and programming

If a machine fails due to corrupted software or a cyber event, you may need:

• Specific “electronic equipment” wording
• Cyber insurance (for malicious causes)

Design or workmanship defects

Some policies exclude inherent design defects, but may still cover resulting damage. The distinction matters.

How sums insured are set (and how to avoid underinsurance)

Machinery breakdown cover usually needs a declared value for each item or for a group of items.

Common valuation approaches:

• Replacement as new (recommended for critical kit)
• Indemnity value (market value, factoring age and wear)

For PCB assembly equipment, replacement as new can be eye-watering, especially for high-end placement machines and X-ray systems. But underinsuring can lead to:

• Reduced claim payments (average clause)
• Cashflow gaps when you need speed

Practical tip: keep a simple asset register with:

• Make/model/serial
• Year
• Replacement cost estimate
• Service provider details

Excesses, waiting periods, and claim triggers

Expect:

• A monetary excess per claim
• Possibly a time excess for BI (e.g., 48 hours)

You’ll want to understand:

• Whether multiple failures from one event count as one claim
• How “sudden and unforeseen” is defined
• Whether “testing and commissioning” costs are included

Risk management: what insurers like to see

Better controls can mean better terms. For PCB and assembly operations, these are strong signals:

Preventive maintenance and service records

• Planned maintenance schedule
• OEM or approved engineer servicing
• Documented calibration and validation

Power protection

• UPS for controls and servers
• Surge protection and power conditioning
• Regular electrical inspections

Environmental controls

• Temperature/humidity monitoring
• Dust extraction and filter changes
• ESD controls and audits

Spares strategy

• Critical spares on site (drives, sensors, belts)
• Supplier lead times documented

Contingency planning

• Outsourcing options
• Alternative production routing
• Customer communication plan

Claims: what to do when a machine fails

When breakdown happens, speed and documentation matter.

1. Make safe: isolate power, stop the line, prevent further damage.
2. Notify your broker/insurer early: especially if BI may apply.
3. Document the incident: photos, error codes, operator notes.
4. Keep failed parts: insurers may want inspection.
5. Track downtime and costs: labour, overtime, outsourcing, lost output.
6. Get repair reports: engineer findings, root cause, parts replaced.

How machinery breakdown fits with other covers

Machinery breakdown is usually one piece of a sensible insurance stack:

• Commercial property: fire/flood/theft for premises and contents
• Business interruption: often tied to property damage; add breakdown BI if needed
• Cyber insurance: if a cyber event could stop production or corrupt systems
• Employers’ liability and public/products liability: for injury and third-party claims
• Professional indemnity: if you design electronics or provide advice/services
• Goods in transit: for high-value components and finished boards

Who needs it most?

Machinery breakdown insurance is particularly relevant if:

• You rely on a small number of critical machines
• Lead times for parts/engineers are long
• You have tight customer delivery SLAs
• You run high-mix, low-volume work where rework and delays are costly
• Your equipment is financed or leased (contracts may require cover)

Quick checklist before you buy

• List your critical machines and support plant
• Decide replacement as new vs indemnity value
• Add breakdown business interruption if downtime would hurt cashflow
• Confirm cover for expediting expenses
• Check exclusions: consumables, software, wear and tear, maintenance
• Confirm security and maintenance requirements
• Set realistic indemnity period and gross profit figure
