Ultimate Guide to FFC Selection Criteria
When you select an FFC for your LCD, you need to understand the main criteria that affect compatibility, reliability, and performance. This ultimate guide helps you make informed decisions for your display project. You will learn how to match pitch size, contact count, actuator type, and other key features to your application. INEED provides customized solutions and strict quality control, so you can trust your connector selection.
Pitch Size and Number of Contacts
Pitch size and the number of contacts are the foundation of any FFC flexible cable choice. Pitch size means the distance from the center of one contact to the center of the next. You must match the pitch specifications of your LCD connector to the FFC. If you choose the wrong pitch, the cable will not fit, and you risk poor signal transmission or even damage.
The number of contacts determines how many signals or power lines you can connect. More contacts allow for more complex data transmission, but you need to ensure your LCD and FFC match exactly. Always check the datasheet for both your display and the FFC flexible cable.
Tip: Use a table to compare your LCD connector and FFC options. This makes it easier to spot mismatches before you order.
| Criteria | Description |
|---|---|
| Pitch Size | Match the LCD connector’s pitch to the FFC for proper fit and signal requirements. |
| Number of Contacts | Ensure the FFC has the exact number of contacts needed for your display’s data transmission. |
You can find FFCs with pitch sizes from 0.4mm to 1.25mm and up to 96 contacts. This flexibility helps you meet the needs of high-density or simple LCD applications.
Actuator Type: ZIF and LIF
The actuator type affects how you insert and secure the FFC into the connector. You will see two main types: ZIF (Zero Insertion Force) and LIF (Low Insertion Force).
ZIF connectors use a locking mechanism. You insert the FFC flexible cable with almost no force, then lock it in place. This design reduces wear on the contacts and improves reliability for static applications. LIF connectors do not have a lock. You push the cable into place, which is faster but may not hold as firmly in high-vibration environments.
Here is a quick comparison:
| Feature | ZIF Connectors | LIF Connectors |
|---|---|---|
| Reliability | Good for static use, limited cycles (25-30) | More durable for frequent connections |
| Ease of Use | Locking mechanism, larger footprint | Simple design, easy handling |
| Cost | Higher due to complexity | More economical for low-pin-count uses |
| Application | Not for frequent unplugging or vibration | Good for simple, stable connections |
You should choose the actuator type based on how often you will connect and disconnect the cable, and the environment where your LCD will operate.
Contact Location and Structure
Contact location and structure play a big role in connector selection. You need to decide if you want contacts on the same side or on opposite sides of the FFC. This choice depends on your LCD’s connector design. If you mismatch the contact location, the cable will not make a proper connection.
The structure of the contact also matters. Some FFCs have reinforced ends for better insertion tolerance. Others use gold plating for improved signal quality and reliability. Always check your LCD’s requirements and match the FFC structure for the best performance.
Note: Proper contact alignment ensures stable signal transmission and reduces the risk of connection failure.
Current, Temperature, and Durability
You must consider the current rating, temperature range, and durability of your FFC flexible cable. These factors affect long-term reliability and safety.
- Current rating: Most FFCs for LCDs handle between 0.5A and 1.0A per contact. For backlight power, a conservative estimate is 250mA per pin. Always check your display’s power needs and choose an FFC that meets or exceeds them.
