Prepreg 7628: High-Performance Glass-Epoxy Composite for Advanced PCB Manufacturing

Prepreg 7628 offers numerous advantages that make it an exceptional choice for electronic manufacturing applications. First, its pre-impregnated nature ensures consistent resin content throughout the material, eliminating the variability often encountered with traditional glass fabric materials. This uniformity translates to reliable performance and predictable manufacturing outcomes. The material's excellent dimensional stability helps maintain precise circuit patterns and prevents warping during thermal cycling, which is crucial for maintaining the integrity of complex multilayer PCB designs. The balanced weave structure of the 7628 style glass fabric provides superior handling characteristics and prevents distortion during the lamination process. Additionally, the material exhibits outstanding electrical properties, including low dielectric constant and loss tangent, which are essential for high-frequency applications. The controlled resin content ensures optimal flow during lamination, creating strong interlayer adhesion while maintaining consistent thickness across the board. From a manufacturing perspective, prepreg 7628 offers excellent machinability and can be easily processed using standard PCB fabrication equipment. The material's thermal resistance makes it suitable for lead-free soldering processes, while its flame-retardant properties meet various international safety standards. The combination of mechanical strength and electrical performance makes it an ideal choice for applications requiring both structural integrity and reliable signal transmission.
