F4BMX-1/2 Teflon PCBの概要
F4BMX-1/2 is a high-performance laminate crafted by layering imported varnished glass cloth with Teflon resin and Polytrtrafluoroethylene film. This product adheres to scientific formulations and stringent technological processes, offering superior electrical performance compared to the F4B series. It features a broader range of dielectric constants, lower dielectric loss tangent, increased resistance, and more stable performance. The use of imported woven glass fabric ensures consistency in the properties of the laminate.

Cutting/Punching Strength:
- For thickness <1mm, no burrs after cutting; minimum space between two punching holes is 0.55mm, 剥離はありません.
- For thickness >1mm, no burrs after cutting; minimum space between two punching holes is 1.10mm, 剥離はありません.
皮の強度 (for 1oz copper):
- Normal state: ≥18N/cm; No bubble or delamination peel strength: ≥15N/cm (in constant humidity and temperature, and kept in molten solder at 260 degree Celsius±2 degree Celsius for 20 秒).
化学物質
The chemical etching method for PCB can be used without altering the dielectric properties of the laminate. Plating through holes requires sodium treatment or plasma treatment. Hot Air Level temperature must not exceed 253 degrees Celsius and cannot be repeated.
