Discover how GELIN’s innovative entry and backup boards are transforming the PCB manufacturing process, ensuring precision, efficiency, and cost-effectiveness.

In the intricate world of PCB manufacturing, the unsung heroes are often the materials that support the process itself. Today, we’re shining a light on the crucial role played by GELIN’s entry and backup boards, which are indispensable in the drilling phase of PCB production.

What is an Entry Board?

At GELIN, we refer to this essential component as the “Entry Board.” Positioned strategically on the copper plate during the PCB drilling process, the entry board’s primary role is to safeguard the PCB board from damage.

Key Functions of GELIN Entry Boards:

1. Surface Protection: Shields the copper foil surface or the conductive layer of the base plate from the pressure foot during drilling.
2. Bit Stability: Locks the drill bit in place, minimizing swing and wonder, ensuring precise hole positioning and preventing bit breakage.
3. Burr Prevention: Mitigates the formation of burrs and caps on the substrate, reducing imperfections.
4. Thermal Management: Facilitates heat dissipation as the drill bit works, keeping temperatures in check.
5. Bit Maintenance: Cleans the drill bit groove, preventing greasy and dirty holes, and reducing wear and tear.

The Backup Board: A Silent Guardian

The material that lies beneath the circuit board, making direct contact with the machine surface during drilling, is what we call the “Backup Board.”

Primary Roles of GELIN Backup Boards:

1. Burr Restraint: Effectively reduces exit burrs for a cleaner finish.
2. Machine Surface Protection: Safeguards the drilling machine’s surface as it penetrates through the PCB board.
3. Thermal Regulation: Assists in heat management, lowering the temperature of the drill bit.
4. Bit Cleaning: Keeps the drill bit clean, ensuring optimal performance.
5. Precision Enhancement: Provides a stabilizing effect, improving overall drilling precision.

The Impact on PCB Drilling

The entry and backup boards are not just auxiliary materials; they are pivotal to the mechanical drilling of PCBs. They influence product quality, process feasibility, and economic viability. As PCB drilling technology advances, the importance of these boards grows, presenting a diversified and functional evolution. Yet, they also challenge the industry to control costs effectively.
