3. pq Clegtrani s Desktop Reflow Oven For Your Electronic Needs User Manual n ON Thank you for purchasing the Desktop Reflow Oven When we designed our reflow ovens we had two things in mind simplicity and budget priced So we decided to take a different approach To help keep the costs down we used an ordinary toaster oven stripped the insides and designed a digital controller that monitors and directly controls the temperature by using a thermocouple temperature sensor and a solid state relay SSR By using thermocouples it allowed us to get accurate temperature readings while handling the high temperature demands of the reflow oven The solid state relay SSR is used to control the heating elements using a software based PID program Our goal is to get hobbyists entered into the world of SMD Soldering Block Diagram Here is a diagram of the different buttons and areas on the controller unit emperature Slope Start Button Selection vd amp Sq tle tranigs Desktop Reflow Oven y For Your Electronic Needs User Manual Getting Started After unpacking the reflow oven you will find two trays Choose which one you would like to use and place it inside the oven on the top rack Unpack the power adapter and plug it into the back of the controller unit Unpack the thermocouple and carefully insert the end of the thermocouple into the hole in the back of the oven Connect the thermocouple to the screw
