What is an FPC/PCB Pumice Line?

An FPC/PCB Pumice Line is a specialized production line designed for cleaning and surface preparation of flexible printed circuits and printed circuit boards. The line utilizes pumice, a volcanic ash material, to effectively remove contaminants such as dust, oils, and residues from surfaces. This cleaning procedure is vital for ensuring optimal adhesion during subsequent processes like lamination or soldering.

Key Applications of the FPC/PCB Pumice Line

The FPC/PCB Pumice Line serves numerous applications that are crucial in the electronics manufacturing sector. Some of these include:

  • Surface Preparation: Before any surface treatment, the pumice line ensures that the PCB or FPC surface is clean and ready for bonding.
  • Enhanced Adhesion: By removing residues, the pumice line enhances the adhesive properties of various coatings applied to FPCs and PCBs.
  • Decreased Defects: A clean surface minimizes the risk of defects that can arise from dirt or oil interference during manufacturing.
  • Improved Durability: The approach used in the pumice line contributes to the overall longevity and performance of the electronic products.
