兆福公司除了中國大陸工廠具專業製造頻率控制相關產品已有30年經驗外，同時也是英國Sarantel公司在台灣／中國大陸及香港專利的Geohelix GPS 天線產品總代理，同時銷售SEIKO EPSON ／ EPSON TOYOCOM 產品。因為與EPSON產品範圍及規格不盡相同，正好補足產品線的缺口，兆福在代理與製造業務間取得極佳的平衡，因此無論尺寸及頻率範圍從最普遍到最精密、最小尺寸都非常齊全，如石英振盪器、Oscillator , TCXO, VCXO, VCO, OCXO,，還有陶瓷振盪器（濾波器）、SAW FILTER／ RESONATOR等。兆福成為擁有全系列完整產品的最佳供應平台。舉凡頻率控制零件、無線通訊、衛星定位、藍芽、資訊家電等都是兆福產品線主要的應用範圍
