Reflow resistance

Webthe daisy chain resistance are used to monitor the yield before and after reflow testing, and to qualify the endurance behavior in the 85 C /85% RH stress test. WebHot bar reflow soldering (emphasis on the “hot bar” part) enables multiple connections simultaneously by applying heat and force to pre-fluxed and pre-tinned parts using a thermode (hot bar). The electrical current required to heat the thermode is supplied by a pulsed heat power supply.
