PCB Fiberglass Tissue Solution for Booming CCL Industry
1.New era in electronic sector and how Union Composites plays a role:
Artificial intelligence (AI), electric vehicles (EVs) and consumer electronics are advancing rapidly, driving continuous innovation across the electronics sector. More electronic-grade woven glass cloth is being diverted to make high-end FR-4 Copper Clad Laminates (CCL) for premium Printed Circuit Board (PCB) applications. This shift is creating new opportunities for CEM-3 CCL, offering an excellent balance between performance and affordability. Union Composites is committed to supporting this evolving market with high-quality PCB fiberglass tissue designed for CEM-series laminates.
2.What do you need to know about PCB Fiberglass Tissue:
PCB Fiberglass tissue is a non-woven glass fiber reinforcement material. It is manufactured from chopped E-glass fibers using a wet-laid forming process followed by binder curing. Unlike woven fiberglass fabric, fiberglass tissue provides a uniform fiber structure with excellent resin absorption and dimensional stability. In CEM-3 laminates, it serves as the core reinforcing layer, working together with fiberglass cloth, epoxy resin, and copper foil to enhance performance while maintaining competitive manufacturing costs.
3.How does Union Composites excel in making PCB Fiberglass Tissue:
Union Composites’ PCB fiberglass tissue is developed to meet the demanding requirements of CCL, and subsequently PCB manufacturers. Our product strictly complies with IPC-4130 requirements for electronic glass reinforcement materials, and has been successfully adopted by leading listed manufacturers in mass production. Stable performance throughout the lamination process is attributed to the following key product features:
* Smooth and uniform appearance
* Excellent electrical insulation
* Outstanding heat resistance
* Superior compatibility with epoxy resin systems
* Stable basis weight and fiber distribution
