. If the peak temperature of Lyra Reflow Oven is too low, it is easy to produce cold junctions and insufficient wetting; if Lyra Reflow Oven is too high, the epoxy resin substrate and the plastic part will be coking and delamination prone to occur, and excessive eutectic metal compounds will form and cause brittleness

. Generally, the highest temperature is about 235?. If temperature is too high, epoxy base-panels and plastic parts may be coked and delaminated easily

leave the soldering pad and some of them may hide under the chip components. When reflow soldering, these solder paste will melt and then be forced out from under the sheet-type resistor-capacitor units, thus forming the tin sweats. It can be seen from
