LQRelay1

Are relays limiting your process efficiency?

As production environments evolve, selecting power relays based solely on specifications is no longer enough. Mounting compatibility is becoming a critical factor.
By adopting reflow-compatible relays, manufacturers can centralize their soldering processes—leading to improved substrate productivity and streamlined operations.

Traditionally, power relays are mounted using flow soldering, which often requires additional labor and cost. In-house setups demand expensive jigs, while outsourcing increases both time and expenses.

Panasonic’s LQ relay reflow-compatible type offers a compact design, supports high current, and fits seamlessly into reflow soldering processes.
With the same terminal layout as the standard LQ relay, it enables easy replacement—allowing you to solve mounting challenges without changing your existing process.

LQRelay_problem_1

Mounting Process Complexity

Flow soldering requires a separate process in addition to reflow, increasing workload and the risk of errors.
It also demands jigs and flow pallet design, adding to setup time and cost.
Outsourcing the process further raises expenses and lead time.

LQRelay_problem_2

Miniaturization vs. High Current

As devices become smaller, selecting high-current relays becomes more difficult.
Applications like inverters and air-conditioning control boards require high-capacity switching in limited space.
To meet current demands, relays tend to grow in size—reducing layout flexibility and conflicting with chassis design due to height and footprint constraints.

LQRelay_problem_3

Environmental Compliance Burden

Stricter global regulations (RoHS, REACH) and customer requirements have made environmental compliance a must from the design stage.
For products targeting overseas markets, even the presence of halogens can determine whether a component is accepted—making specification checks and certification handling increasingly burdensome.

Q.

What is the difference between the standard versus reflow soldering types of the LQ Relay?

A.

The external dimensions and ratings are nearly identical, however the reflow soldering type is optimized for heat resistance which can support reflow soldering.
The footprint is also compatible, allowing existing board designs to be migrated smoothly without changing the PCB layout.

Q.

Can the reflow type be mounted using flow soldering?

A.

The reflow type is designed primarily for reflow soldering, however flow (wave) soldering may be possible under certain conditions. Please contact us for specific implementation requirements.

Q.

Are there any recommended conditions or temperature profile for the reflow soldering procedure?

A.

Yes, we provide technical documentation that includes recommended reflow soldering profiles. We can offer guidance of the optimal conditions based on your temperature settings and the material of the mounting substrate.

Q.

Can I use it for overseas products?

A.

Yes, the LQ Relay complies with major international standards such as UL and VDE which makes it suitable for use in global markets. Procurement and technical support are also available locally through our overseas sales offices.

Q.

Is it possible to provide samples or obtain reliability data?

A.

Yes, we will respond individually based on the application and required data. Evaluation samples and test data will be provided promptly and can be tailored to the customer’s design stage accordingly.
