Product process description:

Process flow: smt+ packaging

IQc over-furnace experiment: all self-purchased plastic molded patch materials must be reflow soldered

Solder paste requirements: Ag3.0/Cu0.5/20-38uM

A/B surface: first paste the P8 surface, the heavier material bottom non-pad position point on the appropriate amount of red plastic, to prevent the second side when the piece is lost

Reflow soldering temperature setting: Preheating and constant temperature zone operation are based on "Reflow Heater Temperature Management Specification". The maximum temperature of reflow soldering is between 245-247 degrees, and the welding time of over 230 °C is controlled by 40-60S (the temperature of the LED lamp is appropriately reduced (243-245 degrees) when the LED lamp is on one side of the high temperature sensitive oven LED lamp.

No dip process
