Buyers Guides

Introduction

Investing in SMT equipment is a long-term strategic decision, not just a purchasing action.
Many SMT investment failures happen not because of poor machines—but because the wrong questions were never asked.

This guide outlines the key questions every manufacturer should ask before committing to SMT investment.

1. What Problem Are We Actually Solving?

Before selecting equipment, clarify:

• Are we improving throughput?

• Are we reducing defects or rework?

• Are we increasing flexibility or capacity?

Buying equipment without a clear problem definition often leads to underutilization.

2. What Is Our Product Mix Today and Tomorrow?

Consider:

• High-mix vs high-volume production

• PCB size variation

• Component complexity

Future product uncertainty should influence machine selection more than current volume.

3. Do We Need Inline Automation or Offline Flexibility?

Inline solutions are ideal for:

• Stable, high-volume production

Offline solutions are better for:

• Engineering validation

• High-mix production

• Bottleneck recovery

A hybrid approach often delivers better ROI.

4. What Is the True Bottleneck in Our Line?

Adding equipment does not always increase output.

Ask:

• Which process step limits throughput?

• Is inspection or transfer causing line blocking?

• Are manual steps slowing production?

Invest where it matters most.

5. How Will Inspection and Quality Be Managed?

Key considerations:

• Inspection coverage requirements

• False call management

• Recovery and rework flow

Inspection strategy should be planned together with production—not added later.

6. Is Our Factory Infrastructure Ready?

Check readiness in:

• Power and air supply

• Space and layout

• Logistics and material flow

Infrastructure gaps can delay commissioning and increase cost.

7. What Is the Total Cost of Ownership (TCO)?

Beyond purchase price, include:

• Maintenance and spare parts

• Training and support

• Downtime cost

• Upgrade potential

Lower upfront cost does not always mean lower lifetime cost.

8. How Easily Can We Scale or Upgrade Later?

Future-proof your investment by asking:

• Can the system be expanded?

• Is automation modular?

• Are software upgrades supported?

Rigid systems limit long-term growth.

9. Who Will Operate and Maintain the Equipment?

Consider:

• Skill level of operators

• Engineering support availability

• Training requirements

Advanced equipment without trained personnel increases risk.

10. Do We Have a Clear ROI and Payback Plan?

Every SMT investment should answer:

• Expected productivity gain

• Quality improvement impact

• Payback timeline

If ROI cannot be clearly explained, the investment is likely premature.

Common SMT Investment Mistakes to Avoid

• Buying the fastest machine instead of the right one

• Over-automating unstable processes

• Ignoring inspection and buffering strategy

• Underestimating changeover and maintenance effort

When to Seek External Expertise

If internal experience is limited, consider:

• Line layout consulting

• Process optimization studies

• Pilot testing before full investment

Conclusion

Successful SMT investment starts with asking the right questions, not selecting the right brand.
Clear objectives, realistic planning, and flexibility ensure long-term value and sustainable growth.
