Hi, i want to buy this unit to replace bad LED's on TV backlight LED strips. Do you still have the unit? If so, is it still working good? Are you still satisfied with it? Hope to hear from you soon. Many thanks in advance
When you reflow a PCB, there are temperature profiles to follow to not overheat components, On a plate, you do this manually - reflow ovens have profiles built in that they follow.
On a PCB assembly line, each small part receives a small dab of glue to hold it in place before it goes through the reflow oven. The glue holds the parts in place during the reflow process. Most prototype designers will try to keep all surface mount parts on one side of the board so they don't have to worry about this issue.
@@picklerix6162 No we don't use glue for reflow. Solder has surface tension and unless there is a big ass heavy part with tiny pads (a transformer for example) the tension keeps them in place while upside down. Glue is used for wave soldering smt parts.
@@Chevroletcelebrity you'd love having the potentially toxic fumes released from the heated pcb, heated plastics and solder in the eyes and airways. but also, they could be doing other experiments there, such as resin fumes (or microplastics) released from 3d printing. we dont know how well ventilated their space is and that stuff is bad for your lungs so you need a mask minimum..
