Compared with thin 1080/106 fiberglass for mobile HDI boards, 7628 (210g/㎡, 0.173mm) features higher rigidity and better dimensional stability, making it irreplaceable for:
Server power thick multilayer boards
EV charging & energy storage BMS circuit boards
Industrial frequency converter & PLC control boards
Poor-quality 7628 cloth easily leads to PCB warping, poor resin penetration and high reject rate.
At KF, we adopt precision loom weaving & surface desizing process for our 7628 fiberglass cloth, to guarantee consistent flatness between batches, helping PCB factories reduce production loss.
We supply 7628 glass cloth + carbon fiber fabric + aramid prepreg all together. If your factory needs reliable electronic reinforcement materials, feel free to connect.
