ACF – Anisotropic Conductive Film

• A cheap and reliable way of Bonding

• Can be done two ways

- Using ACF Tape

- Using ACP (Anisotropic Conductive Paste)

11 / Hardware Presentation11

ACF – What do you need to repair?

• Dust Free Enviroment

• ACF Tape

• ACP

- Anisotropic Conduct Paste

• Correct Equipment

- Heating equipment

- PCB Fixtures

• Complete ESD environment

12 / Hardware Presentation12

ACF – Acceptable Equipment

• ACF Hot Bar machine

• Spot Heater

• PCB Jig

• Paste

13 / Hardware Presentation13

ACF – Unacceptable Equipment

• Simple Hot Bar Machine

- No Guidelines

- Human Error

- Non ESD.

- Susceptible to Dust

- No Reliability
