Common SMEMA & Automation Problems in SMT Lines

SMEMA-related issues are one of the most common causes of line instability and unexpected downtime in SMT factories.

Typical problems include:

• PCB not transferring between machines

• SMEMA signal mismatch between different brands

• Frequent board blocking or false stop signals

• Manual intervention required between processes

• New equipment not compatible with existing line

• Inconsistent automation level across the line

These issues often appear during line expansion, equipment replacement, or factory upgrades.

Our SMEMA & Automation Engineering Approach

We do not treat SMEMA as just a cable connection.
We treat it as a complete PCB transfer and automation logic system.

Our engineering approach includes:

• Analysis of upstream and downstream machine behavior

• Verification of SMEMA signal logic and timing

• Matching conveyor speed, sensors, and board stops

• Design of buffer and accumulation strategies

• Integration of manual, semi-automatic, and automatic stations

• Troubleshooting of existing SMEMA communication problems

Every solution is designed to be stable, predictable, and production-ready.

SMEMA & Automation Solution Modules

Our solutions are built using modular automation components, allowing flexible integration into existing SMT lines.

Typical solution modules include:

• SMT Conveyor Systems (link, inspection, cooling, drop door)

• SMT Buffer / NG Buffer

• PCB Loader & Unloader

• SMEMA Interface Cables & Accessories

• Sensors, board stops, and actuators

• Offline inspection and manual stations integration

👉 Modules are selected based on actual line behavior, not theoretical diagrams.

Typical Automation Application Scenarios

Our SMEMA and automation solutions are widely used in:

• Mixed-brand SMT production lines

• Manual lines upgrading to semi-automation

• Line expansion with limited factory space

• Replacement of old or incompatible equipment

• Integration of offline AOI / SPI stations

• Low-volume, high-mix SMT production

We focus on making different machines work together reliably.

Frequently Asked Questions (FAQ)

What is SMEMA in SMT production?
SMEMA is a standard interface used for PCB transfer communication between SMT machines. It controls board ready and board available signals to ensure safe and coordinated transfer.

Can you solve SMEMA problems without replacing machines?
In many cases, yes. Issues can often be solved by adjusting conveyors, sensors, buffers, or signal logic without replacing main machines.

Do you supply SMEMA accessories and hardware?
Yes. We supply SMEMA cables, interface accessories, conveyors, buffers, and related automation components.

Can you support overseas SMT factories?
Yes. We support global SMT automation projects with remote engineering assistance and documentation.
