Dear All I have a question for the reflow machine. I'm using Vitronics(Mr933+)reflow. The peak temperature of the (Chip, LED, SOT) component higher than (QFP,LGA) about 4 degree when i measured proflie. All of them on the same board . I don't know w

Temperature vs time is what soldering is all about. The faster you run your conveyor, the more heat will have to come from the pot for a given assembly. Example: You heat the board to 200F top side through the preheaters. Eutectic 63/37 melts at 361.

I have a board, 4 spacers needed to be soldered on the board first with the normal 62Sn37Pb alloy. Then, capacitors are manually soldered on the boards. The density of the board is quite high. If we wave soldered capacitors first, there will be no p
