F4BTM-2 Radio frequency PCB material Technical Specifications

F4BTM-2 Radio frequency PCB material is laminated by laying up of the imported varnished glass cloth with Teflon PCB resin and filler with the Nano-ceramic, according to the scientific formulation and strict technology process. This product takes advantages over F4BM series in the electrical performance improved the heat dissipation and have the small thermal expansion coefficient.

Strength

Thickness<1mm,no burrs after cutting,minimum space between two punching holes is 0.55mm,no delamination.

Thickness³1mm,no burrs after cutting,minimum space between two punching holes is 1.10mm,no delamination.

Peel strength(1oz copper)

Normal state:≥18N/cm;No bubble, delamination, peel strength≥15N/cm(in the constant humidity and temperature, and keep in the melting solder of 265 degree Celsius±2 degree Celsius for 20 seconds).

Thermal stress

After solder float,260ºC,10s,≥3 times,no delamination and blister.

Chemical Property

According to the properties of laminate,the chemical etching method for PCB can be used. The dielectric properties of laminate are not changed. The plating through hole can be done,but the sodium treatment or the plasma treatment must be used.
