High Speed Circuit - Interposer Board

What is Interposer Board? PCB Interposer Board is an adapter product used for connection testing, applied to various types of testing or changing existing structures or improving the safety and stability of circuit boards.

In the application of ATE, The signal from the Probe card is converted through the intermediary layer of the Interposer, allowing the probe head to receive the signal and smoothly transmit it to the testing machine for interpretation.

Types and functions of Interposer Board

1. Interface Interposer Board: The main function of this Interposer Board is to convert one port into a different type of port, commonly used in computers, audio and video equipment, electronic instruments, and network devices;

2. Expansion Board: This Interposer Board can be used to expand the number of interfaces on the circuit board to support more device connections;

3. Protection board: When the voltage of the input and output signals is different or unstable, the Interposer Board can act as a protective circuit to protect the equipment from damage;

4. Signal converter: This Interposer Board can convert analog signals into digital signals, or convert digital signals into analog signals, commonly used in battery management, peripheral control, and communication devices;

5. Power Converter: This Interposer Board is used to convert input power into other stable power outputs. Common application scenarios include televisions, speakers, and TV set-top boxes;

6. Logic conversion board: This Interposer Board can be used to convert a certain logic level into another logic level. Common application scenarios include electronic switches, temperature control, and computer interiors.

Interposer Board has a wide range of application scenarios, including computers, network communication, industrial automation, automotive electronics, IC test board, and medical equipment. Attention should be paid when using Interposer Board.

1. Select the appropriate Interposer Board model: Choose the appropriate Interposer Board model according to actual needs to avoid phase issues or incompatibility;

2. Pay attention to the matching between the Interposer Board and the device: correctly match the interface between the Interposer Board and the device to avoid problems such as interface mismatch, plug detachment, or poor contact;

3. Ensure the stability of the power supply: When using a power converter, a stable power supply should be used to avoid damage to the equipment caused by unstable power supply;

4. Take appropriate protective measures: When using the protective board, appropriate protective measures should be taken between the Interposer Board and the equipment to avoid damage to the circuit board.

Interposer Board is a very practical circuit board that brings great convenience to our lives and work by expanding the number of interfaces, converting interface types, and protecting circuit boards. When using Interposer Board, attention should be paid to factors such as appropriate model, correct interface matching, and stable power supply to ensure the stability and safety of the device.
