Rogers 2929 Bondply Series Data Sheet

Rogers prepreg 2929 has a hydrocarbon base material without glass fiber reinforcement inside and is a thermoset material. Rogers 2929 Bond Sheet has a coefficient of thermal expansion of 50ppm/oC in the 0-150 degree range. Under D24/23 conditions, its moisture absorption rate is 0.1%.


Rogers 2929 bondply is a non-reinforced, hydrocarbon-based thin-film adhesive system for high-performance, high-reliability multilayer structures. Low dielectric constant (2.9) and loss tangent (<0.003) at microwave frequencies make it ideal for bonding multi-layer boards (MLBs) made with PTFE composites such as RT/duroid6000 and RO3000 series laminates, filled water carbon resin composites such as RO4000 core and special thin core laminates. A proprietary cross-linked resin system makes this thin-film adhesive system compatible with sequential bonding processes, while the controlled flow characteristics provide excellent blind-through fill capability and potential for designs requiring blind vias and/or buried cavities. Predictable reduction rate. 2929 bondply is compatible with traditional flat press and autoclave bonding.


The film is currently available in 0.0015 inch, 0.002 inch, and 0.003 inch thick sheets. Individual sheets can be stacked to create a thicker bond layer. The unreinforced film can be bonded to the inner layer to facilitate simultaneous processing of cuts through the core and adhesive layers and to facilitate the use of the conductive paste to form vias. The easy-to-release carrier film protects the adhesive layer from contamination during processing, conductive paste screening, and MLB booking.

What is the difference between Rogers 2929 membrane and 4450T?

RO4450T prepreg is also a ceramic-filled, low-loss bonding material of special fiber-opened glass cloth. Its dielectric constant is 3.2-3.3, which better enriches RO4835T and the existing RO4000 laminate material product series, with 3 mils, 4 Three thicknesses, mil, and 5 mils, are available. RO4450T prepreg material has very good dielectric constant tolerance control to provide consistent circuit performance; has a low z-axis thermal expansion coefficient to ensure the reliability of plated vias, and is compatible with standard epoxy/glass (FR-4 ) is compatible with the processing flow. For multi-layer designs that require multiple consecutive laminations, these materials are ideal as the fully cured RO4000 product can withstand multiple lamination cycles. Likewise, the RO4450T prepreg has a flame retardant rating of UL 94 V-0 and is compatible with lead-free processes. 2929 Bond Sheet is a non-reinforced thermoset resin-based film (1.5, 2, and 3 mil thickness) bonding system for high-performance, high-reliability multilayer construction. The patented cross-linking resin system enables the film bonding system to be compatible with multiple lamination processes, while the controlled flow of glue can fill blind holes. Key Benefits Low dielectric constant (2.9) and tangent loss angle (.003) Ideal for multi-layer bonding Compatible with conventional processing methods Can be used with a variety of material types including PTFE Reliable multiple laminations.


2929 Prepreg is a thin, non-glass reinforced hydrocarbon bond sheet designed for high-performance, high-reliability multilayer construction. The product features a low dielectric constant (2.9) and low dielectric loss (<0.003) at microwave frequencies, making it ideal for making multi-layer boards with RT/duroidlSl6000, RO4000, and RO3000 series materials. This unique cross-linked resin system enables the thin adhesive sheet to be used in multiple continuous lamination processes. At the same time, its controllable fluidity has excellent blind hole filling ability, and the design requirements of blind grooves can be met by controlling the back-cut ratio.

The 2929 adhesive sheet can be laminated using conventional flatbed and vacuum chamber presses. It is currently available in thicknesses of 0.0015, 0.002, and 0.003 inches (0.038, 0.051, and 0.076mm) and can be added to the required thickness. This thin adhesive sheet without glass cloth reinforcement can be pre-pressed to the inner core board so that the core board and the adhesive layer can be grooved at the same time, and the carrier film can protect the adhesive sheet during machining and multi-layer boards. No contamination when boarding.
