特点：
ST450是模拟、闭环温度控制的400W红外预热台。
ST450可以单独使用，也可以和带有PCB夹具的ST300、ST325、ST350组合使用。
The ST 450 is an analog, closed loop, temperature controlled convective 1500 W preheater. The heating area is 140mm x 140mm (5.5" x 5.5"). This preheater is ideal for applicati*** where focused hot air is desirable or where cooling air is required after the application of heat such as area array applicati***.
