The Inline OLB Bonding Machine is a sophisticated piece of equipment used in the manufacturing process of electronic devices, particularly in the assembly of components such as (ceramic substrates) and PCBs (Printed Circuit Boards). This machine is designed to streamline the bonding process, ensuring high precision and efficiency.
Key Features of the Inline OLB Bonding Machine
Advanced Alignment System
The machine is equipped with a robotic arm and vacuum tool collet that can accurately pick up and place components such as heat sinks, ceramic substrates, and PCBs. This ensures precise alignment during the bonding process.
Dispensing System
It includes a dispenser for applying thermal paste and adhesive paste. The thermal paste is applied to the heat sink surface aligned with the ceramic substrate, while the adhesive paste is applied to the area aligned with the PCB. This ensures proper thermal management and strong bonding.
ACF Taping Machine
The ACF (Anisotropic Conductive Film) Taping Machine is used to apply ACF to the PADs of the ceramic substrate and PCB. This is a crucial step in the bonding process, as it ensures reliable electrical connections.
COF Pre-bonder and Main Bonder
The machine features a COF (Chip on Film) Pre-bonder and Main Bonder. The pre-bonder is used to align and bond the COF to the ceramic substrate, while the main bonder applies main pressure to the ACF position, ensuring a strong and reliable bond.
UV Resin Coating and Hardening
After the bonding process, the machine applies UV resin to the edges of the COF PADs and uses a UV exposure unit to cure and harden the resin. This provides additional protection and stability to the assembled components.
Function Testing and Inspection
The machine includes a function tester and pattern vision machine for testing and inspecting the assembled components. This ensures that the final product meets the required quality standards.
