PCB Pressing Carrier Plate is an essential key auxiliary material in the printed circuit board (PCB) manufacturing process. As a professional manufacturer of pressing buffer pads, we fully understand the importance of this component in the multi-layer board pressing process. The PCB pressing carrier plate, also known as a pressing buffer pad or pressing plate, is mainly used in the PCB lamination process to evenly distribute pressure, buffer shocks, and protect the circuit board surface from damage.
In modern PCB manufacturing, especially in the production of high-precision multi-layer boards, the pressing carrier plate plays multiple key roles:
Even pressure distribution: Ensure uniform force application across all areas of the multilayer board
Temperature buffering: Balance temperature gradients during the thermal pressing process
Surface protection: Prevent damage to copper foil and insulation layers under high pressure
Dimensional stability: Maintain the dimensional accuracy of the PCB board under high temperature and pressure

Application techniques for PCB lamination carrier plates
Correct Usage Method
To fully utilize the performance of PCB lamination carrier plates, the following usage guidelines should be followed:
Preprocessing: Before first use, the carrier should undergo 2-3 times of empty lamination to stabilize performance
Cleaning and Maintenance: Residual substances on the surface should be removed after each use
Placement Positioning: Ensure correct positioning in the press machine
Complementary use: Better results can be achieved when used with suitable release film
Periodic Inspection: Check the surface condition after every 50 lamination cycles
Common Issues and Solutions
Based on our experience as a press buffer pad manufacturer, the following are common problems and their solutions:
Problem 1: The PCB becomes uneven after pressing
Cause: Uneven thickness of the carrier plate or it has aged
Solution: Replace with a new carrier plate and check the flatness of the press platform
Problem 2: Poor bonding along the board edge
Cause: Mismatched carrier plate size or inaccurate positioning
Solution: Use the correct size carrier tray and adjust the locating pins
Problem 3: Marks appear on the surface
Cause: Contamination or damage on the carrier tray surface
Solution: Clean or replace the carrier tray, and check the quality of the release film
