DF12 smt type board to board connector DF12NC (3.0)-14DS are engineered to meet the specific requirements and challenges presented by the automotive environment, which can include exposure to vibrations, temperature variations, moisture, and other harsh conditions.

Introduction of  DF12 smt type 0.5mm pitch board to board connector DF12NC (3.0)-14DS ：

 1. DF12 smt type board to board connector DF12NC (3.0)-14DS is high-density design and it can achieve more pin configurations in limited space. It also meet the needs of signal transmission and power distribution. Some products have a floating structure that can automatically absorb assembly errors between substrates, reduce precision alignment requirements, and increase guide column design to ensure smooth insertion and removal.

 2.Connection method: There are usually two connection methods, parallel and vertical, which can meet different circuit board layout requirements. Some products support two configurations: vertical stacking and right angle connection. There are multiple options for vertical stacking height, such as 8-30mm.

 3. Connection method: There are usually two connection methods, parallel and vertical, which can meet different circuit board layout requirements. Some products support two configurations: vertical stacking and right angle connection. There are multiple options for vertical stacking height, such as 8-30mm.

 4.Performance parameters: The working temperature range is generally around -40 ℃ to+85 ℃. The rated current varies depending on the product. Some products can support 0.5A current with a single signal pin, and some connectors can also integrate high current channels, such as 3A/pin x 4 wires. The contact resistance is generally within a few tens of milliohms, and the insulation resistance is usually not less than 100 megaohms.

5.Application areas: Widely used in industries such as power systems, communication networks, industrial automation, medical equipment, office equipment, home appliances, military manufacturing, etc., especially suitable for equipment with high signal transmission requirements such as 5G base stations, servers, AI acceleration cards, robot control boards, etc.

Function of  DF12 smt type board to board connector DF12NC (3.0)-14DS ：

 1. High density integration: With a narrow spacing of 0.5mm, more pins can be arranged in a limited space, supporting various combinations of signal pins and power pins such as 20/40/60, achieving signal transmission and power distribution, meeting the requirements of miniaturization and high performance of electronic devices.

 2.High speed signal transmission: Some products support high-speed protocols such as PCIe Gen4, which can achieve a data transmission rate of 16Gbps. By optimizing differential signal layout and using low loss materials, signal crosstalk is reduced to ensure the integrity of data transmission at high frequencies.

 3. Adapt to multiple layouts: with configurations such as vertical stacking and right angle connections, the vertical stacking height can be selected between 8-30mm, which can adapt to different internal space layouts of devices and provide flexibility for modular design.

 4.High assembly tolerance: Some products have a floating compensation of ± 0.6mm (X/Y direction), which can automatically absorb assembly errors between substrates, reduce precision alignment requirements, and are suitable for large-scale assembly on automated production lines. At the same time, the large guide column design ensures smooth insertion and removal, improving connection reliability

 5.Easy installation and maintenance: Usually packaged with tape, compatible with automated surface mounting machine technology, can improve production efficiency and consistency. The end of the substrate mounting part can be visually inspected or confirmed by an automatic optical inspection device for easy mounting inspection

 6.Strong environmental adaptability: Some products can adapt to a temperature range of -40 ℃ to+125 ℃, and the contact terminals have self-cleaning function, which can eliminate dust and other foreign objects, and can reliably work in harsh environments such as in vehicles.

 7. Stable electrical performance: It has low contact resistance, generally within a few tens of milliohms, and insulation resistance is usually not less than 100 megaohms, which can ensure stable current transmission, reduce signal attenuation and leakage problems.

Here are some recommendations of  DF12 smt type board to board connector DF12NC (3.0)-14DS ：

  1.Recommended Manual Soldering Condition (SMT) ：Soldering iron temperature : 350ç, Soldering time : Within 3 seconds

  2. Recommended Screen Thickness and Open Area Ratio(Pattern Area Ratio)：0.12mm        Open area ratio : 70%

  3. Board Warp(SMT) ：Maxmum 0.02mm in the connector center area, based on both connector edge

  4. Cleaning Condition ：Refer to “Nylon Connector Use Handbook”

Cautions ：

   1.The receptacle is designed with the contacts exposed. Touching the contacts with bare hands may cause contact failure or damage to the device due to static electricity.
  2. Insertion/extraction when not mounted to the board may result in damage or contact deformation.
  3.Avoid securing the board only with the connector. Please use other methods to secure the board.
  4.Excessive prying during insertion and extraction may result in damage.
  5.Do not apply flux that will result in flux rise during manual soldering.
  6.The color of the mold may differ slightly depending on the production lot however this does not affect the performance.
