FAQ:
What range of pin specifications can you customize?
- We support customization for various pin diameters (e.g., 0.45mm, 0.5mm) and any length. Pin materials can be selected from Kovar, Iron-Nickel, or copper-core composites depending on your soldering or bonding needs, with gold plating options for maximum reliability.
Can Yolanda customize specific pinouts or lengths if my project requires it
- Certainly. With our in-house tooling center, we support customized non-standard pin configurations (3-pin, 4-pin, or more)and any pin length. We maintain flexible MOQs to assist you in rapid prototyping and verification during the R&D stage.
Do Yolanda’s header products comply with environmental reliability standards?
- Our designs meet international standards. Every batch undergoes rigorous thermal shock (-65°C to +175°C) and damp heat testing, ensuring long-term stability in outdoor or aerospace equipment.
How do you ensure signal purity for high-frequency sensing applications?
- We use high-purity, low-dielectric-loss glass preforms and precisely control sealing gaps. This design effectively minimizes parasitic capacitance and signal interference between pins, ensuring accurate high-frequency data transmission.
Do your pin coatings support Gold Wire Bonding?
- Yes. We offer Electrolytic or Electroless Gold plating compliant with MIL-G-45204. Plating thickness is customizable (up to 3μm) based on your process requirements. Our high-purity gold layer ensures excellent wettability, significantly improving your wire bonding success rate.
Can Yolanda provide TO-CAN integrated with lenses for optical applications?
- Yes. We provide headers integrated with flat windows, ball lenses, or aspherical lenses. Our precision sealing ensures lens coaxiality and hermeticity, reducing your assembly complexity and improving overall system coupling efficiency.
