Harwin Archer .5 and Archer .8 are suitable for compact electronics applications requiring high-speed board-to-board signal connections, including:

• Embedded computing
• Building automation
• Smart metering
• IoT modules

These applications often require compact interconnect solutions that can support data transfer between stacked PCBs or removable modules while maintaining efficient use of PCB space.

Engineering Background:

Mezzanine connectors are commonly used when two PCBs need to be connected in a stacked board configuration. This helps designers route signals between a motherboard and a daughterboard while keeping the overall assembly compact.

For high-speed electronics, connector selection should consider more than pitch alone. Engineers may need to review data rate, board-to-board height, contact count, temperature range, mechanical durability, and assembly requirements.

According to the Archer datasheet, Archer .5 offers a smaller 0.5 mm pitch with 8 mm board-to-board height, while Archer .8 offers 0.8 mm pitch with 5 mm board-to-board height. Archer .8 also supports the higher listed data rate of up to 12 GHz / 24 Gb/s and a wider upper operating temperature of +125°C.

Why Are There Different FPC Locking Mechanisms?

Designed to Support Different PCB Layout and Assembly Requirements.

Flexible Printed Circuit connectors provide a compact method of connecting flexible circuits to printed circuit boards where available space, connector orientation, and cable routing must be carefully considered.

Selecting an FPC connector is not only about choosing the correct pitch. The locking mechanism, contact orientation, connector height, cable thickness, and insertion direction can all influence how easily the connector fits into the PCB layout and assembly process.

The Harwin Solutions FPC Connector Range includes multiple locking mechanisms, contact configurations, and fine-pitch options, allowing engineers to compare connector styles according to their specific mechanical and PCB design requirements.

 

Key Features: 

✔ Available in 0.30 mm and 0.50 mm pitch options
✔ Front Flip Lock, Back Flip Lock, and Slide Lock actuator types
✔ Bottom Contact, Upper Contact, and Dual Contact configurations
✔ Low-profile SMT designs for compact PCB assemblies
✔ Multiple connector heights and compatible cable thickness options
✔ Rated up to 50 V and 0.5 A, depending on model
✔ Individual technical drawings available for each part number

Application and Market

Harwin Solutions FPC Connectors are suitable for electronic designs that require compact board-to-flex connections, including:

✔ Display and interface modules
✔ Embedded electronic devices
✔ Control boards
✔ Portable electronic equipment
✔ Compact PCB assemblies
✔ Electronic modules using flexible printed circuits

The suitability of each connector depends on the selected part number, cable orientation, PCB layout, and overall system requirements.

Engineering Background:

Different PCB layouts do not always provide the same level of access around the connector. In some designs, the flexible cable may need to be inserted from the front, while other layouts may require access from the opposite side or a sliding actuator due to surrounding components and limited mechanical space.

• Front Flip Lock connectors use an actuator that opens from the front, providing direct access for FPC insertion.
• Back Flip Lock connectors open from the opposite side, offering an alternative assembly direction where rear access is preferred.
• Slide Lock connectors use a sliding actuator to secure the flexible circuit after insertion, providing another option for designs where a flip-style actuator may not suit the available layout.

Understanding these differences helps engineers evaluate which locking mechanism, contact position, and connector orientation best fits the intended PCB design.

 

Harwin Solution

The Harwin Solutions FPC Connector Range provides multiple connector configurations for compact PCB and flexible circuit designs.

With Front Flip Lock, Back Flip Lock, and Slide Lock options, together with Bottom, Upper, and Dual Contact configurations, engineers can compare different connector styles according to their required cable direction, assembly access, and board layout.

The range also includes 0.30 mm and 0.50 mm pitch options, multiple product heights, and different cable thickness requirements. Individual technical drawings are available for each part number to support connector evaluation and mechanical design review.

The case study application involved a UAV platform operating up to 4,500 meters with temperature and humidity certification. The system required continuous 60A current from the battery to a high-current payload through a cable-to-board connection. The cable connector also required solder cups to support secure cable termination.

For engineers, this means the connector must do more than simply complete the circuit. It must provide a stable power path, reduce the risk of intermittent power loss and support reliable operation in a compact UAV design.

Harwin Solution

Harwin Kona provides the required high-current connection for this UAV battery power application.

The solution uses a Kona 2-contact female cable connector mated to a male PCB connector, delivering the high-reliability connection and 60A current-carrying capacity required by the payload system.
