Flow soldering 与 reflow的区别
WebFlow soldering shall not be applied to the capacitor designed for reflow soldering only. Cracks due to thermal stress or dissolution of electrodes (leaching) may occur and may result in deterioration of adhesion (shear strength) or decrease in capacitance. Some large size and small size capacitors are unsuitable for flow soldering.Consult us ... Websoldering process in that the reflow of solder is accomplished using a heating element called a thermode which is heated and cooled down for each connection. Pressure is applied during the entire cycle including heating, reflow, and cooling. A pulse-heated control delivers energy to the thermode, which is mounted on the reflow soldering head.
